Don’t be held hostage by the IT expert

What happens when IT changes direction or reorganizes and an expert suddenly feels threatened? If an organization has relied heavily on a particular individual, can he hold it hostage?
Every IT department has its technical experts--whether their specialty is data base, communications, or a particular application or system that is unique.

Over time, these individuals hone their skills to make them "one of a kind" problem solvers and also consummate advisers on new IT projects.

These individuals often develop their technical skills because early in their IT careers, they recognize that they don't have a taste for management--so they must find some other way to advance themselves and their earning potential.

The best of these experts is a six-figure/year employee--who can even out-earn his manager.

What happens, though, when IT changes direction or reorganizes and an expert suddenly feels threatened? If an organization has relied heavily on a particular individual, can he hold it hostage? And if he does, what do you do?

First, the best antidote to any situation like this is to have an open, supportive and communicative culture in your organization. When an organization is in the midst of layoffs and constant closed-door meetings, no one, even the most experienced technical people, feels secure. If they are far away from management, they are also likely to feel that their knowledge is all that they have to protect themselves from being pushed out the door. Consequently, even if you are an IT manager who is faced with having to reduce staff, do it as openly as you can and also provide career placement (or even in-company transfer) support to those affected.

Second, management and staff succession planning should be part of your disaster recovery plan's risk management for critical employees who become unavailable. A system of cross training and "understudy" education to ensure that you have backups for all IT positions—including the CIO—facilitates this. If cross-training and understudy activities are integrally part of your everyday practices and they are uniformly applied to the CIO on down, there is likely to be less staff anxiety.

Third, learn how to "bite the bullet" when a key IT contributor becomes uncooperative and protective of his knowledge base. This lack of cooperation can affect department work. NO ONE, including the CIO, should obstruct getting the work out that IT is responsible for.

Some years ago, I was managing a mission-critical project that entailed the development of an online stock trading system. I needed the services of a transaction processing expert for the system software we were running applications on. The individual I wanted for the project was absolutely brilliant in her field—but she proved to be uncooperative and unwilling to work on the project. I didn't wait around. Instead, I brought in a much more junior person for the project. We got the work done that was needed, although it took longer. Nevertheless, the project was successful, the junior person learned valuable skills that would be used again--and we had avoided being "held hostage" by an uncooperative employee.

When I talk with CIOs, it always surprises me how few include contingency planning for critical technical personnel in their DR plans. Instead, personnel contingency plans focus on replacements for management people in the event they become unavailable in a disaster. The reality is that key technical contributors are just as important as managers--and sometimes more so--when it comes down to the IT work that must be done.

"We changed our IT culture significantly to one of service, and we realigned departments within our organization several years ago," said one financial services CIO. "The process was necessary, but in reorganizing, I also knew that I was risking losing key technical contributors who didn't want to be part of a cross-disciplinary service culture, but who instead preferred to operate in their traditional technical expertise silos."

The CIO's worst fears came true when several of his top six-figure experts opted to leave for other companies that had organizations that they were more comfortable with.

What was the CIO's saving grace?

"I had anticipated and included the loss of key technical contributors in my risk management strategy, had discussed it with my management and had obtained their buyoff. I was ready to move in with a temporary staff of outside IT consultants until we could rehire for the positions," he said.

Today, the organization is back on its feet with a strong in-house IT staff, and a new service orientation that is taking it to new heights

VMware NSX Network Virtualization Design Guide

IT organizations have gained significant benefits as a direct result of server virtualization. Server consolidation reduced physical complexity, increased operational efficiency, and the ability to dynamically re-purpose underlying resources to quickly and optimally meet the needs of increasingly dynamic business applications are just a handful of the gains that have already been realized.

Now, VMware's Software Defined Data Center (SDDC) architecture is extending virtualization technologies across the entire physical data center infrastructure. VMware NSX, the network virtualization platform is a key product in the SDDC architecture. With NSX, virtualization now delivers for networking what it has already delivered for compute and storage.

In much the same way that server virtualization programmatically creates, snapshots, deletes and restores software-based virtual machines (VMs), NSX network virtualization programmatically creates, snapshots, deletes, and restores software-based virtual networks. The result is a completely transformative approach to networking that not only enables data center managers to achieve orders of magnitude better agility and economics, but also allows for a vastly simplified operational model for the underlying physical network.

With the ability to be deployed on any IP network, including both existing traditional networking models and next generation fabric architectures from any vendor, NSX is a completely non-disruptive solution. In fact, with NSX, the physical network infrastructure you already have is all you need to deploy a software defined data center. 

Download the VMware NSX Network Virtualization Design Guide.

This document is targeted toward virtualization and network architects interested in deploying VMware network virtualization solutions.

vCAP5-DCD: FAIL– Here is what I learnt today

All I have to say is “Wow, that's not even close to what I was expecting!

First off, time is a real factor:

As I was reading other peoples blogs, they kept mentioning that they finished with only 2 minutes left I just kept thinking to myself I write fast (I do most exams in sub 30 minutes) so this won’t be a problem for me.

I clicked finish with 6 minutes left, and I watched the clock like a hawk once I only had 2 hours remaining and was less than 1/3 done (not a great feeling).

There are 3 Types of Questions:

I knew about the regular pick one / two type of questions and the design style questions but I was quite surprised when I got my first of 17 scenario type questions.  These are drag and drop style where there is a list on the left you have to match up with things on the right based on a scenario / diagram given to you, sounds simple right… wrong!

I found some of these to be harder than the design questions.

What makes these so tough was some times it a 1 to 1 match, some time its a 1 to many match and sometimes you don't have to match everything.  The harder of these seemed to be asking 6 – 8 separate questions all related to the same scenario.

Design questions take a long time:

I spent well over 20 minutes on most of the design questions, and get ready to re-do some of them more than once. 

After spending about 15 minutes on my second design question, I got an adobe error message on my screen and the design engine froze.  I clicked “no” to stopping the script then finally had to call the admin in to reboot my PC.  This ate up about 4 minutes of my time, but when the PC came back up, I had to start the question over again.

On another question, after spending a good 20 minutes on it, I noticed one line that changed the design.  I started trying to drag things to the garbage can, but some of the items “stuck” together so I had to hit start again and spent another 10 minutes re-creating the design.

Some VERY technical questions:

I didn't expect to see anything uber technical on this exam, but there were a few questions that dealt with advanced options / configuration settings.

So what now:

I have to wait 14 days to re-take this exam, so for the next 14 days I will be focusing on the Forbes & Scott’s Design Guide and the Clustering Deepdive by Duncan and Frank along with reading some of the more technical readings outlined on the exam Blueprint.

I won’t be spending anymore time with the “Official” Certification Guide, which should be called Guideline instead.  I put too much faith into this guide and I paid the price for it.  It does cover all of the topics on the exam, but doesn't have enough of the technical details to help you answer most of the exam questions.

vCAP5-DCD Study Review

As I site here on the eve of my vCAP5-DCD exam, I am looking back over all the notes and ideas I had scribbled down at the beginning of my studies and realize that it has been quite a journey to get me to where I (hopefully) am prepared to write a design exam.

One thing I would like to note is the incredible job people in the community have done mapping topics and information to the objectives on the blue print. As I review some of these study guides and blogs I am astounded that people were able to pull such abstract concepts from the readings and place them, some what neatly, under each of the objectives.  Without the community, I’m not sure I would of been able to align all the qualities, factors, design thoughts and considerations into the knowledge that will be tested tomorrow on the exam.

My main source of study has been the following:

Big thanks to everyone mentioned above, and everyone who has ever blogged or shared their experience with the vCAP-DCD exam, if I pass I owe it all to you.

Wish me luck,

F5 and VMware Integration Streamlines the App Provisioning Process

Many organizations have taken advantage of the operational efficiencies that come from server virtualization. These efficiencies have reduced the time to deploy new applications from weeks to days. Until now, however, the process for provisioning the necessary infrastructure services to run those enterprise applications has remained a mostly manual and time-consuming process.

This can diminish the gains initially achieved by server virtualization and can hinder the adoption of cloud computing. The integration of F5 and VMware products helps solve these challenges. VMware NSX transforms network operations and economics in the data center by enabling neverbefore-possible service delivery speed, increasing agility, and dramatically reducing both the capital and operational costs associated with networking and security improvements.

With F5® BIG-IQ™ Cloud, IT administrators can provide the full suite of services offered by BIG-IP® products—such as BIG-IP® Local Traffic Manager™ (LTM), BIG-IP Global Traffic Manager™, BIG-IP Access Policy Manager®, and others—directly from within NSX Manager as part of the normal virtual machine deployment sequence. This shortens the all-inclusive application provisioning process from days to just minutes.

Setting Frame Rates and Resolution for Real-Time Audio-Video on Horizon View Clients (2053644)

The following information was taken from VMware KB2053644

 

Details

Real-Time Audio-Video (RTAV), introduced in VMware Horizon View 5.2 Feature Pack 2, allows 
webcam and audio-in devices to be redirected from a local client system to a remote desktop. 
With RTAV, Horizon View users can run Skype, Webex, Google Hangouts, and other conferencing 
applications on their virtual desktops.

After you install RTAV, the feature works on your desktops without any further configuration. On client 
systems, the default webcam frame rate is 15 frames per second. The default webcam image resolution 
is 320x240 pixels. The default settings are recommended for most webcam and audio applications. 

You can modify these settings to change the user experience in the conferencing application.

You can configure group policy settings that control the maximum frame rate and image resolution on 
your Horizon View desktops. For details, see the VMware Horizon View 5.2 Feature Pack Installation and

Administration document at 
https://www.vmware.com/pdf/horizon-view/horizon-view-52-feature-pack-document.pdf.

 

In addition, you can configure the frame rate and resolution on your client systems. This article describes how to 
configure these settings on client systems and offers guidelines to help you determine how best to set these values 
in your environment.

NOTE: Audio configuration settings are not available for RTAV.

Solution

On View Client systems, you can configure the webcam frame rate and image resolution up to the maximum values 
specified in the group policy settings on the desktops. If you specify a value on a client that exceeds the maximum 
value set on the desktop, the value is capped at the maximum desktop value. 

You can adjust frame rates from 1 fps up to a maximum of 25 fps and resolution up to a maximum of 1920x1080. 
However, RTAV cannot guarantee that a high resolution at a fast frame rate can be supported on all devices 
or in all environments. 

Configure RTAV Settings on View Client Systems   

1. Start the Windows Registry Editor (regedit.exe).

2. Navigate to the following registry key: 

Windows Operating System

Registry key

64-bit

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\VMware, Inc.\VMware VDM\RTAV

32-bit

HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\RTAV 


3. Set registry values. 

Registry Value

Default Value

Description

IsDisabled  

0

Determines whether RTAV is enabled or disabled.
RTAV is enabled by default. (This value is not in effect.)  To disable RTAV on this client, set this value to 1.

srcWCamFrameWidth

Not set

Determines the image width. The value defaults to a hardcoded value of 320 pixels.
You can change the image width to any pixel value.

srcWCamFrameHeight

Not set

Determines the image height. The value defaults a hardcoded value of 240 pixels.
You can change the image height to any pixel value.

srcWCamFrameRate

Not set

Determines the frame rate. The value defaults to 15 fps.
You can change the frame rate to any value.

srcAudioInId** 

Not set

Determines the preferred microphone (audio-in device). When this value is not set, RTAV uses the default recording device set in the Windows operating system Sound control. 
You can specify any microphone connected to (or built into) the client system.

srcWCamId**

Not set

Determines the preferred webcam. When this value is not set, the webcam is selected automatically by system enumeration. 
You can specify any webcam connected to (or built into) the client system.


4. Save your changes and exit the registry.

5. Start a new call in your 3rd-party application.

**The 
srcAudioInId and srcWCamId values let you set a preferred audio device and a preferred webcam,

if more than one device is connected to the client system.  RTAV uses the preferred device in conferencing

or other 3rd-party application sessions. If a preferred device is not available, RTAV uses the next

available webcam, as determined by system enumeration, or the default audio recording device set in the

Windows Sound control.  

In most environments, there is no need to set a preferred audio device. You can simply select a default

audio recording device in the Windows Sound control. For information about selecting a preferred webcam

and a default microphone, see the VMware Horizon View 5.2 Feature Pack Installation and

Administration document at 
https://www.vmware.com/pdf/horizon-view/horizon-view-52-feature-pack-document.pdf.

Guidelines for Setting Frame Rate and Resolution  

If your users are on a high-latency network with limited bandwidth, you might want to reduce the default values

to maintain a working video image or to manage the available bandwidth for each user.  

Raising the resolution and frame rate increases the demand on network bandwidth. Depending on your

environment, you might want to run scaling tests to determine the performance impact of raising these limits.  

If you find that after changing these values, video does not display well with your 3rd-party application,

you might revert to the default values.

For example, Skype displays video well at 320x240 resolution at 15 fps. With sufficient bandwidth, Skype

also works at 640x480 resolution, but certain Skype versions do not perform as well with this resolution. 

If you change the resolution on a client, you must stop and restart the Skype application before making

another call.  If you change the resolution while Skype is running and make another call, the video

image might be distorted or incorrect. 

In general, devices support a specific set of resolutions. Not all devices support all resolutions. If you

configure a resolution that a webcam does not support, RTAV samples the resolutions that are closest to

the one that was requested until a supported resolution is found.  RTAV implements client-side scaling up

to the resolution supported by the device. 

Depending on client-side scaling, the CPU cycles needed to encode and decode the video data, and

network bandwidth limitations, you might not be able to achieve a required frame rate for the requested

resolution. RTAV cannot guarantee a desired frame rate for any specified resolution on any device.

At the end of a call, you can determine frame rates by examining the debug logs on View Agent, which

show the resultant frame rate achieved. The View Client logs show the transmitted frame rate. 

For some 3rd-party applications, not all resolutions will be supported.

Although RTAV has been tested with--and supports--several 3rd-party applications, and will work with

many other standard applications, it is possible that some 3rd-party applications are not supported by

RTAV.

VCAP5-DCD–Exam Prep Materials and Upcoming Videos

So I have spent the past 2 weeks going through the VMware Exam Blue Print for the VCAP5-DCD exam and have come up with the following materials / strategy to start in my preparations for writing this exam.

The Blue Print itself has links to many (many) other resources, I have been reading most of them, but am having a hard time digging out the nuggets of information that can be found on other study guides (see below), or al least that information that I feel may be on the exam.  So for my own exam preparation, I have decided to create video presentations that will be guided by the Blue Print itself.  This will not be a replacements for the vBrownBag series (again see below) but a different way of looking at the info presented on the Blue Print which will in turn help me digest and understand the pieces that have been pulled from the additional readings.

I am still planning on using the “VCAP5-DCD Official Cert Guide” for the majority of my study, but it has been delayed for shipping yet again (should of just bought the Kindle edition) so I will be waiting a few more weeks until I get my hands on it.

To supplement the above, I also plan to utilize the following resources:

As for the upcoming videos, once I figure out how to properly record them, I will start to create the presentations and delivering them as I have time, so stay tuned.

What I hope to see at VMware 2013

This year it looks like I will be lucky enough to attend my first VMworld Smile

As I have been searching the blogs for session information and the who’s who of the presentations, I started to put together a list of what I hope to see at this years event.

The following are areas that I hope VMware makes major announcements / changes to:

The Horizon Mash Up

With Horizon View (include ThinApp in there), Mirage and Horizon Workspace, VMware has 3 great but only sort of tied together products.

I am really hoping to see Horizon 6.0 announced which will allow for Mirage to deploy and manage ThinApp’s to View Desktops and through the Horizon Workspace along with AppBlast finally being GA and tied into the suite to run apps through a browser.

vCloud Director for EUC

Wouldn't it be cool if end users (with approval of course) could provision their own desktops and / or application suites?  If VMware does announce some sort of Horizon 6.0, I hope it also includes the ability to self provision desktops similar to what is possible with vCloud Director.

Self Tuning Resource Pools (aka DRS on Steroids)

With vCOPS, we now know what is “normal” for our VM Guests and we can also run reports to figure out which ones are Over Provisioned against that normal baseline.  If VMware can take this normal range and automatically decrease or increase the resources that are assigned to a given VM, think of the consolidation ratios we would be able to achieve.

Servers & Desktops in the Same Pool

This one still bugs me.  For VMware to state that it is “best practice” to separate your Server and Desktop workloads onto separate physical hardware controlled by separate vCenter Servers, to me it doesn't make sense since it breaks the whole model of true consolidation.  Today, even with resource reservations and limits, it is a requirement for any large scale VDI deployment to be separated, but if VMware can produce something like the DRS on Steroids, I truly believe that Desktops and Servers should be able to play nicely on the same resources, controlled by the same vCenter server,

I’m not sure if any of this will be addressed at this years VMworld, but i cant wait to be there to find out.

VCAP5-DCD Exam Preparation

One of my goals for this year was to get one of the VCAP5 certifications. My company has just given me the green light to go ahead and start preparing for the Data Center Design (DCD) exam and I must admit, I am a bit scared and over whelmed at the idea if writing this exam.

The reason that this exam frightens me is that it is based on “design solutions” which, unlike the VCP exam, doesn't necessarily have defined information you must know to pass, its really based on ones ability to digest customer requirements and deliver “the best” solution for that scenario.

The over whelming part is the massive amount of readings that are listed on the exams blueprint and the incredible length of the exam itself. I know there were 10,000+ pages of suggested readings for the VCP exam, but with a good amount of hands on knowledge (which I was lucky to have already) most of the questions could be answered without having read all the materials. I do take comfort that 92 to 94 of the questions will be multiple choice / drag and drop and the other 8 to 6 will be the Design scenarios.

Over the next couple of weeks I will post up my notes that I am studying from as well as links to other blogs / study sheets that I come across and find useful.

I have pre-ordered a copy of Paul McSharry’s book “VCAP5-DCD Official Cert Guide” and am really looking forward to getting my hands on it and checking it against my study notes to ensure I am on the right path with my studies.

Wish me luck and check back often for my study note updates, hopefully they will help in your studies for the VCAP5-DCD exam.

Available now: VMware Technical Journal, Summer 2013

For those like me who love reading research papers by developers you might want to head over to labs.vmware.com as today a new version of the VMware Technical Journal was released, the summer 2013 edition. You can download it as a PDF on the website, or you can read the individual articles straight in your web browser. Below you can find the Table of Content, and the titles convinced me that these are worth reading. Personally I found the "Redefining ESXi IO Multipathing in the Flash ERA" very interesting… but I suggest you read all of them as it typically gives a good hint of what VMware engineering is working on now / or in the future!

Introduction Memory Overcommitment in the ESX Server Redefining ESXi IO Multipathing in the Flash Era Methodology for Performance Analysis of VMware vSphere under Tier-1 Applications vATM: VMware vSphere Adaptive Task Management An Anomaly Event Correlation Engine: Identifying Root Causes, Bottlenecks, and Black Swans in IT Environments Simplifying Virtualization Management with Graph Databases Autonomous Resource Sharing for Multi-Threaded Workloads in Virtualized Servers

Upgrading vSphere 5.1 → 5.1U1a

Upgrading vSphere 5.1 → 5.1U1a
http://feedly.com/k/11hkKoa

BACKGROUND

Upon arriving at my new organization the end of February of this year, a co-worker had already migrated most of our virtual infrastructure to vSphere 5.1, utilizing  SQL 2012 as the vCenter Server database. In doing so, they noticed some "bugginess" with the infrastructure – unable to log in using the 'thick' Client, the Performance tab → Overview button performance statistics wouldn't display, as well as the Web Client not working in Internet Explorer (would work with Firefox).

After a couple calls to VMware support, multiple Google queries, and a few twitter comments, I never did get a definite answer as to the cause of our issues. I assumed it was due to the fact we were using SQL 2012 for our DB as it was not listed in VMware's Compatibility Matrix, but I couldn't find/get a definite answer, not even from VMware's support (I'd give my thoughts on my discussions with them, but don't won't to digress too much).

Anyway, I really wanted to get all these issues rectified. When VMware released U1 in April, I heard bits & pieces in the "community" on twitter that this Release would rectify the issues I was having. But, I began hearing grumblings about the stability of the U1 patch (vSphere login issues), which was confirmed by VMware as noted by this KB. Then last week. VMware released U1a, and after reading over the Release Notes, it looked like this patch was indeed the answer to my problems….err….well….my vSphere problems. After upgrading my environment, to this point it seems all the issues we were experiencing are now rectified. As such, I'd like to provide the steps I took for a successful upgrade which, overall, was pretty seamless and painless……and surprisingly quick!

PREREQUISITES

Before proceeding with upgrading your infrastructure, I highly recommend reviewing VMware's Upgrade Guide which provides greater detail of all upgrade procedures as your environment may not be the same as mine. In my envirnment, I have 13 Hosts separated into 4 Clusters & Datacenters but all within the same vCenter Server. We do not use a multi-site, Linked Clone environment, nor do we segregate vCenter Components on separate servers (i.e SSO, Inventory Service, etc. is all on the same server). Before upgrading, I recommend performing the following tasks:

1. Open your DB managment tool (i.e. SQL Management Studio) and take a backup of the vCenter database
2. Log onto your vCenter Server and take a backup of all your Component services SSL certs (look in the Upgrade Guide that's linked above for the path location to each Component SSL folder)
3. Attain the credentials used for the vCenter Server database
3. Attain your SSO admin credentials (the username is admin@System-Domain; upon initial install of SSO you had to provide this account a password. Hopefully you securely documented it for retrieval)
4. Take a snapshot of your vCenter Server, assuming it's a VM

UPGRADE – VCENTER SERVER & COMPONENTS

1. If not already done so, download both vCenter Server and vSphere ESXi 5.1 U1a (I recommend the offline bundle for ESXi, but download the package that you're familiar with in doing vSphere upgrades)
2.  Double-click the autorun.exe file from the vCenter Server download (if you downloaded the .iso, it will first need to be extracted)

3. As noted in the Upgrade Guide, the following components need to be upgraded IN ORDER:
a. Select vCenter Single Sign On (NOT the Simple Install), then click the Install button; follow the wizard then click Install (reference on pg. 64, Upgrade Guide). Provide the SSO account credentials when prompted. A reboot of vCenter may be needed upon completion of the SSO upgrade
b. After completing the SSO upgrade, select VMware vSphere Web Client then click the Install button; again, follow the wizard then click Install (reference on pg. 78, Upgrade Guide)
c. At this point, it is recommended to open a web browser & attempt to log into the Web Client. First, log in using the SSO account (admin@System-Domain) and verify domain connectivity; then attempt to login using a domain account. If all is successful, continue to 'd.'; else, review troubleshooting steps in the Upgrade Guide
d. Select VMware vCenter Inventory Service, then click the Install button (reference on pg. 80, Upgrade Guide)
e. Select VMware vCenter Server, then click the Install button (reference on pg. 83, Upgrade Guide); provide the vCenter Server database credentials when prompted
4. After upgrading all Components, log into vCenter and verify functionality; if all looks ok, I suggest backing up your SSO configuration as noted on pg. 100 of the Upgrade Guide

UPGRADE – ESXi HOSTS

There are several ways to upgrade your Hosts. Since I personally like doing so using the Offline Bundle with CLI, I will cover that procedure below. You can also upgrade via Update Manage or extracting the vSphere .iso file to a CD and using the Host CD Drive, or by using an installable USB.

1. Upload the Offline Bundle zip file to a Datastore shared by all Hosts. If you have multiple Clusters and those Clusters utilize separate storage arrays (as I do), make sure to upload the .zip to each Cluster's array.
2. Open a Putty (SSH) session to a Host (enable SSH in Configuration tab > Security Profile link if the SSH service is stopped)
3. Within vSphere (thick or Web Client), place the Host in Maintenance Mode (migrate VMs to other Hosts if they don't automatically do so)
4. Once in Maintenance Mode, run the following esxcli command:
esxcli software profile update -d /vmfs/volumes/datastore/vsphere-5.1_update1a.zip -p ESXi-5.1.0-20130402001-standard

(NOTE: to verify which bundle you want to install, you can run the following command:
esxcli software sources profile list -d /vmfs/volumes/datastore/vsphere-5.1_update1a.zip ; I chose to run the "standard" bundle )
5. When the install has successfully completed, you will need to reboot your Host

NOTE: I stole the above screenshot from Christian Mohn's (@h0bbel) post on installing an Offline Bundle here. I referenced his post from Hersey Cartwright's post here (@herseyc)

6. Once the Host is rebooted, you then need to repeat the procedure for each Host. After all Hosts are upgraded, VMware Tools will need to be upgraded on all VMs. Oh, and don't forget to remove the snapshot on your vCenter Server VM.

You have now fully upgraded your vSphere environment! Happy virtualizing!

Does IT eat its young?

This is a great article on how we as IT throw our newbies to the wolves,  or at least put them in charge or backups (because no one else wants to do it)

Does IT eat its young?
By Patrick Gray

In nature, several species routinely eat their young for various reasons, ranging from scarcity of food resources to eliminating future competition for mates. While this behavior has been recorded in humans in various cultures, it's currently manifested metaphorically in several fields where senior personnel obstruct, sabotage, or make life generally difficult for new entrants to the field. In response to one of my recent articles about IT's "woman problem," several readers emailed that whether they agreed or not with IT having a problem with the fairer sex, there was obstructionist behavior toward new entrants.

The not-so-beautiful arts and IT
The field in which I've witnessed this behavior at its worst is in the arts. While my artistic abilities are generally limited to a stick figure or two, I come from a family of artists who have worked in fine art, film, and crafts. When my sister was in film, she'd recount tales of maniacal directors and bosses with inane demands, short tempers, and little more than strings of expletives directed at junior staff.

My own experience with publishing was similar, where literary agents made petty demands and snide remarks until my book was commercially published, when suddenly my calls would be returned and I was no longer treated as a life form slightly lower than pond scum.

When confronted on this behavior, I'm usually given some variation of a "survival of the fittest" explanation-that senior staff in the field exhibit unreasonable behavior to "weed out" those who can't make it in the field, and that engendering "eating of the young" makes the field as a whole stronger.

While less prevalent than in the arts, I've seen similar behavior in IT. A rock star developer or technician is given a pass on poor behavior, and managers and junior staff shrink back in awe when this person enters a room. In other cases, there might be a grizzled veteran who possesses specific knowledge of a complex legacy system and avoids sharing any knowledge or specifications in order to protect his turf and build job security.

In cases where these types of behavior are tolerated, "eating of the young" routinely occurs as those with superior longevity, and hence superior knowledge, use this knowledge as a means to bully new staff. Management is generally complicit in this activity and is willing to destroy its future in order to maintain its current all-stars.

An alternative approach
I've spent most of my working years as a consultant within IT organizations and have always been intrigued by how consultant organizations treat their new staff. Like fields that eat their young, the big consulting companies will identify high-potential talent, even if their experience lies outside the content area in which they'll be consulting. When I started at a large consulting firm, more of my peers had history or marketing degrees rather than degrees in information systems or computer science.

Almost to a fault, these organizations invest heavily in training and early staff development, and then throw the new folks onto a consulting project in a menial role. During the first six months of my career I did everything from mind-numbing massaging of spreadsheets to running errands for office supplies.

While similar to the role of a new staffer on a film, I was never insulted or belittled, and was explicitly told that the goal of this role was to get used to the consulting environment and essentially be "tested" before being given more responsibility. When I was assigned to my next project, "trial period" over, I was expected to perform alongside more senior developers, and soon after was leading my own teams of developers and business analysts.

While the "trial by fire" aspect was similar to the arts, I learned in a supportive environment, and insults, poor behavior, and bullying by more senior staff were simply not tolerated. Those who couldn't do the work were naturally weeded out, and senior staff actively encouraged development and advancement for those who were capable.

There's no harm in breaking in new staff through more menial tasks, and coddling staff doesn't do anyone any favors, especially as terms like "bullying" have become overused to the point that they lack any meaning.

However, there's a difference between "testing" staff through challenging work and subjecting new staff to rudeness, poor behavior, and active harassment in some misguided attempt to toughen them up. Either of the above approaches results in competent senior staff; however, the fine arts-style approach generates cynical, mean-spirited staff that actively eats the young of their industry. Which would you rather have in your organization?

Now available as Rough Cut - Virtualizing Microsoft Business Critical Applications on VMware vSphere 5

The Rough Cuts service from VMware Press gives you exclusive access to an evolving manuscript that you can read online or download as a PDF and print. A Rough Cuts book is not fully edited or completely formatted, but you'll get access to new versions as they are created.

Many organizations are discovering the immense ROI available by virtualizing business critical applications. Microsoft has recently released new versions of many of its most popular and widely used enterprise applications, including Exchange, SQL Server, and Windows Server itself. Meanwhile, VMware has released a powerful new version of its enterprise virtualization platform, vSphere 5.1. Together, these technologies offer powerful new opportunities for cost-effective virtualization, and for migration towards cost-effective private cloud architectures. But successfully integrating them requires deep knowledge. Bridging the gap between Microsoft and VMware worlds, this guide brings together all the knowledge, best practices, and techniques you'll need.

Two leading experts in virtualizing Microsoft business-critical applications on VMware demonstrate how to optimize performance and availability, and what you must do to ensure full support by both Microsoft and VMware. From sizing to architecture to monitoring metrics, they present start-to-finish coverage of virtualizing:

Windows Server 2012 Active Directory Domain Controllers Windows Server 2012 Failover Clusters Exchange Server 2013 SQL Server 2012 SharePoint 2013

For each, example configurations are provided, along with explanations and descriptions of new application features and their relationship to virtualization, as well as tips, tricks, and insights from the authors' own experience. Throughout, diagrams and figures illustrate key points and compare feature sets, and many references to relevant white papers and Knowledge Base articles are also provided.

VXLAN Series – How VTEP Learns and Creates Forwarding Table – Part 5

VXLAN Series – How VTEP Learns and Creates Forwarding Table – Part 5
http://feedly.com/k/11j4O6q

In this post I am going to describe how VTEPs learn about the virtual machines connected to the logical Layer 2 networks. The learning process is quite similar to a transparent bridge function. As transparent bridges learn based on the packets received on the bridge ports, the VTEP also learn based on the inner and outer header of the packets received.

Let's take an example to illustrate the VTEP learning process.

Example Deployment with Two Hosts

As shown in the diagram above there are two Hosts (Host1, Host 2) on which VTEPs are configured, and each host has one virtual machine connected to logical layer 2 network, identified as VXLAN 5001. Both the virtual machines are powered on and both VTEPs have joined the multicast group 239.1.1.100. Each VTEP has its own forwarding table, which is initially empty as shown in the diagram below.

Initial State of the Forwarding Table

How do the forwarding tables get populated?

We will take an example of virtual machine on Host 1 trying to communicate with the virtual machine on the Host 2. First, an ARP request is sent from the virtual machine MAC1 to find the MAC address of the virtual machine on Host 2. The ARP request is a broadcast packet.

Host 2 VTEP – Forwarding table entry

The diagram above shows the packet flow:

Virtual machine on Host1 sends ARP packet with Destination MAC as "FFFFFFFFFFF" VTEP on Host 1 encapsulates the Ethernet broadcast packet into a UDP header with Multicast address "239.1.1.100" as the destination IP address and VTEP address "10.20.10.10" as the Source IP address. The physical network delivers the multicast packet to the hosts that joined the multicast group address "239.1.1.10". The VTEP on Host 2 receives the encapsulated packet. Based on the outer and inner header, it makes an entry in the forwarding table that shows the mapping of the virtual machine MAC address and the VTEP. In this example, the virtual machine MAC1 running on Host 1 is associated with VTEP IP "10.20.10.10". VTEP also checks the segment ID or VXLAN logical network ID (5001) in the external header to decide if the packet has to be delivered on the host or not. The packet is de-encapsulated and delivered to the virtual machine connected on that logical network VXLAN 5001.

The entry in the forwarding table of Host 2 VTEP is used during lookup process. The packet flow shown in the diagram below explains the forwarding table lookup for a unicast packet sent from a virtual machine on Host2.

Host 2 VTEP – Forwarding table Lookup

Virtual Machine MAC2 on Host 2 responds to the ARP request by sending a unicast packet with Destination Ethernet MAC address as MAC1. After receiving the unicast packet, the VTEP on Host 2 performs a lookup in the forwarding table and gets a match for the destination MAC address "MAC1". The VTEP now knows that to deliver the packet to virtual machine MAC1 it has to send it to VTEP with IP address "10.20.10.10". The VTEP creates unicast packet with destination IP address as "10.20.10.10" and sends it out.

The Host1 VTEP receives the unicast packet and it also learns about the location of the virtual machine MAC2 as shown in the diagram below.

Host 1 VTEP – Forwarding table entry

The packet is delivered to Host1 The VTEP on Host 2 receives the encapsulated packet. Based on the outer and inner header, it makes an entry in the forwarding table that shows the mapping of the virtual machine MAC address and the VTEP. In this example, the virtual machine MAC2 running on Host 2 is associated with VTEP IP "10.20.10.11". VTEP also checks the segment ID or VXLAN logical network ID (5001) in the external header to decide if the packet has to be delivered on the host or not. The packet is de-encapsulated and delivered to the virtual machine connected on that logical network VXLAN 5001.

As you can see the forwarding table entries are populated based on the inner and outer header fields of the encapsulated packet. Similar to the transparent bridge the forwarding table entries are removed after aging timer expires. One of the common questions I get is what happens after a virtual machine is vMotioned.

In the next few posts I will cover how the forwarding table entries get modified after vMotion of a virtual machine from one host to another.
