CRHPC has an almost four-year-old Dell EqualLogic storage array in its headquarters data center that's connected to its servers via iSCSI. But when it tried to set up VDI using just the array for storage, application response times were much longer than the 3 milliseconds that CRHPC was aiming for, Rolla said.
Tests with 10 virtual desktops showed that using the cache with PernixData will cut down on response time by about three-quarters, and CRHPC now plans to implement the software in its full VDI rollout, Rolla said.
PernixData should be useful for databases and big data analytics, as well as VDI, said Gartner analyst Chris Wolf. Virtualized storage products from some other vendors, including VMware, have been hard to sell because they were too expensive for what they did, he said.
"As long as the product holds up to what it appears to do on paper, Pernix is going to put a lot of price pressure on some of the more industry heavyweights here," Wolf said.
