GIW Industries, a manufacturer of heavy duty centrifugal slurry equipment, has used PernixData to improve the performance of XenDesktop desktop virtualisation, avoiding the need for a SAN upgrade.

The company has used PernixData FVP to overcome storage performance issues, which can occur when users try to access storage from their virtual desktops.
Lucas McCuistian, the company’s IT, systems and network administrator, said: "Most problems with virtual desktop infrastructure (VDI) come from slow reads and writes to storage. Given that, I was willing to spend money at the beginning of the project to avoid any storage performance problems."
Rather than spend money to boost its existing SAN, GIW Industries deployed Dell SSDs and PernixData FVP software.
PernixData provides a write-back cache, where data is acknowledged to the host before it is written to permanent storage. PernixData FVP allows users to specify that data is written to more than one cache to mitigate against host failure.

"PernixData puts storage reads and writes into high-speed server media for optimal VDI performance and cost effective scale-out,” said McCuistian.
"In addition, we could keep our NetApp array and accompanying data services, avoiding rip and replace headaches. With a new decoupled storage architecture, we cost-effectively rolled out VDI without our end users noticing a difference in performance."
The company plans to triple the size of its VDI environment in the coming years, with PernixData FVP software playing a key role in these plans.
"When you have software like FVP that you can install and then walk away from, it easily becomes a strategic part of your IT infrastructure," said McCuistian.
"Now that we have decoupled our storage, I cannot imagine going to any other type of storage architecture."
