What does it take for a successful VDI implementation?
Let’s think about a few integral steps in getting your VDI project from the whiteboard into production (we don’t have enough space to cover all aspects such as project management, change management, Thin Client selection, etc.)
VDI aka Virtual Desktop Infrastructure relies on your disk subsystem being a stable foundation
in which you can build and grow your VDI environment.
Yet it needs to be flexible enough that it can meet the demands of this environment moving forward too.
Properly sized: How did you size your subsystem prior to rollout?
How many I/O’s did you allocate for each thin client?
How many more I/O’s did you allocate for each application?
How will you handle the ‘exception application’ which is not supported by VDI today?
Do not overlook some applications which require higher uptime than others.
What type of disk drive did you select to achieve this performance metric?
How large are the disk pools you are going to utilize to keep your performance consistent (Proof of Concept, Pilot, Initial rollout, full rollout)?
Did your sizing meet your performance expectorations in your lab?
Protocol selection: What protocol did you select for the backend connectivity (Fibre Channel, FCoE, iSCSI, NFS)?
What protocol does it use to the desktop (I.E. PCoIP or RDP)?
How agile is the protocol you selected? Was it designed for WAN use?
What are the cost implications if other network gear must be ordered?
Are you working w/ the Network team to ensure all aspects of the project are getting the proper attention?
For instance, How did VDI impact your LAN traffic (if applicable)?
How did VDI impact your WAN traffic (if applicable)?
Management: How are you going to keep control over your VDI environment (Roles/Responsibilities)?
Can you quickly integrate management into a directory structure and push out policies to manage all these new devices?
How flexible is your storage offering in assisting with desktop provisioning / creation?
How many golden images will you create & maintain (these might be worlds apart by the time you complete your pilot)?
How will you maintain these images? How much time has been allocated to maintain these images?
Security: Sure, you have locked down the selected OS but what about security at the physical layer have you disabled the USB ports too?
How are your existing security practices today going to be impacted? Will your VDI selection work across a VPN tunnel?
These questions might help get you on your way to VDI success!
