As we all know, the largest cost component of virtualization is typically shared storage. Be it Fibre Channel, NAS or iSCSI, it’s all expensive! Let alone a flash based array like Tinri or Whiptail.

One of the use cases of our OCP (Open Compute Platform) Container (above) gear is to test VMware’s new vSAN product. With vSAN, VMware not only removes the expensive disk cost out of the picture, but they also lock you in to using their Hypervisor exclusively. More »

VMware’s recent announcement of Horizon Suite, Horizon Workspace, Horizon View and Horizon Mirage seems to be lacking mention of ThinApp! So where did it go?

As we both know, VMware Horizon Mirage (formally Wanova) and Horizon View are the same products that they have always been. Horizon Workspace and Horizon Suite are the new kids on the block. With Horizon Suite being just a bundle of View, Mirage and Workspace. More »

After being tasked with creating a “product” SKU around Virtual Desktop, I came up with a VDI Questionnaire for potential VDI customers starting with 200 users. Understanding that its difficult to get all of the customer details clearly defined from a list of questions, I think we cover the majority of the key components.

I would love to hear your feedback

Preliminary List

  1. Is this going to be a hosted or on premise solution?
  2. What services are we expected to provide as part of this quote?
  • Design
  • Hosting
  • Infrastructure Implementation
  • Desktop Image Creation
  • Monitoring and Patching
  • Thin Client deployment
  1. Are we expected to provide VDI aware antivirus or with it come from your current vendor?
  2. Should Xendesktop Training for your staff be included in the quote
  3. Assuming success with the first 200 desktops, are there plans to grow the environment larger?
  4. Is adequate storage for shares in place for user files and user profile storage, or do you need NAS space quoted as well?
  5. What applications are you expecting to see on the desktops?

 Infrastructure

  1. Is this going to be a hosted or on premise solution?
  2. Is Microsoft Active Directory present in the environment? What is the domain functional level?
  3. Does the customer have an ELA which covers VDA pricing?
  4. Are we going to be deploying XenApp along with the VDI deployment?
  5. Is there a preferred storage vendor? Protocol?

Desktop Image

  1. Is there any profile redirection or profile management in place?
  2. Is Windows 7×32 or x64 going to be the desktop image?
  3. As the virtual desktop is very different than traditional desktops, are you aware of specific security requirements that could affect the project timeline?
  4. Are we expected to provide VDI aware antivirus or with it come from your current vendor?
  5. Do you have a list of applications that the environment is expected to support?
  6. Are you currently doing any application virtualization? If so, what vendor?
  7. How many desktop images do you anticipate?
  8. Is adequate storage for shares in place for user files and user profile storage, or do you need NAS space quoted as well?

Networking/Security

  1. Is the customer looking to hand off at layer 2 or 3?
  2. Is there a pair of 10GB uplinks that we will be able to connect the pod to?
  3. Is two-factor authentication (RSA) a requirement?
  4. Is there a local WAN? If so, can we see a Visio of the environment?
  5. Is DHCP currently being used in the environment?
  6. Can multiple dedicated subnets be allocated for the VDI environment, some of which have address capacity requirements?

Clients

  1. Are iDevices and Android devices in scope for external user access?
  2. Is any desktop equipment being reused?
  3. Are we doing physical deployments, are there restrictions that could affect the deployment (ie. No work on user desks between 8 and 5)?
  4. Are there any existing Thin-Clients in place? What models?

Operations/Growth

  1. What type and level of training would you like for your staff?
  2. Assuming success with the first 200 desktops, are there plans to grow the environment larger?
  3. What services are we expected to provide as part of this quote?
  • Design
  • Hosting
  • Infrastructure Implementation
  • Desktop Image Creation
  • Monitoring and Patching
  • Thin Client deployment

Scott’s post on multiple hypervisor’s got me thinking…

Regardless of workload (server, VDI, DR, Test/Dev) I myself only really see one hypervisor out there… VMware. I think so many companies have built their operational policies, processes and procedures around ESX that it is going to be an incredibly difficult migration to something else. I know of one of my customers that is running Citrix XenServer in a XenDesktop environment. Unfortunately, they are unhappy with the solution and there is talk of plans to move to an ESX based XenDesktop solution. I also know of a single customer running Microsoft Hyper-V Server. However, it is not in production or Test/Dev; it’s more of a tinkering environment and an excuse to play with Hyper-V.

Why are customers slow to move to other hypervisors? I think there are a couple other compelling reasons for customers to stick with VMware.

  1. Almost all of my customers are well past 80% virtualized, making it much more difficult to back out and change direction given the investment that they already have.
  2. Almost all of my customers are using other VMware products like Site Recovery Manager and vCloud Director, which utilize VMware’s ESX hypervisor at their core.
  3. VMware has become “comfort food” for IT Professionals, stable, comfortable to use and familiar.

I think these three reasons alone are pretty compelling in terms of the effort (equals money) required to either introduce or replace a VMware Hypervisor environment.

With other customers that I’ve spoken to, another problem for competing hypervisors like XenServer, KVM and Hyper-V, is the price. The free, or near free price seems to subliminally  highlight the difference in feature set when compared to VMware; whether rational or not. Take into account the various State and Local EDucation (SLED) discounts, it’s almost impractical for SLED customers to not deploy VMware and the various VMware applications with the gargantuan feature set.. This, I believe, is the key component for VMware.

As for desktop virtualization aka end-user virtualization; VMware seems to keep holding ground as well. Hypervisors like XenServer and KVM are not widely supported by mainstream monitoring and management platforms (SolarWinds, EM7, etc.). Hyper-V is just recently supported by XenDesktop and is definitely not supported by VMware View. Not to mention, when purchasing View, it’s pretty advantageous to purchase View Premier as your entitled to ESX Enterprise Plus. Not only is that a great deal, but pretty much seals the Hypervisor market share for VMware View.

So that being said, what are you seeing in the general public?
