There are several flash storage vendors, but their biggest limitation is that, because the flash is plugged into a server, it is not available to other servers, PernixData's Kumar said.
"As soon as you plug flash into a local server, you lose the benefits of virtualization like Vmotion," he said. "It's like stepping back several years. Adding flash to a server is not a transparent operation, and it's still a single-host solution."
PernixData FVP, on the other hand, leverages the existing flash storage in customers' servers to decouple capacity and performance, Kumar said. It provides seamless operation and fully supports clustered hypervisors. And it supports both read and write operations. "It includes fault tolerance, with writes replicated so that if a server crashes, the hypervisor moves the data to another server," he said.
Flisher said the software drops right into existing server and storage environments, with no rip-and-replace of existing hardware needed. This provides the functionality of all-flash arrays without the need to purchase new hardware, he said.
eGroup, which also partners with EMC, has found the software to be a great way to add performance to existing customer storage, eGroup's Flisher said.
"EMC Isilon provides scale-out storage capacity, but is not meant for tier-one storage use," he said. "But when we put PernixData in front of Isilon, we saw real high-end read and write performance. We ran all sorts of high-end workloads on Isilon that normally you can't do with Isilon."
PernixData FVP has been in beta testing for about 9 months, with over 20 solution providers and 100 customers participating, Kumar said. The company plans to us a 100-percent channel model for its software, he said.
The software is currently available only for VMware virtualized environments, but next year is slated to be given KVM and Microsoft Hyper-V support, Kumar said.
It is now available in an enterprise version with a list price of $7,500 per VMware ESX host server, and it can be used with an unlimited number of hosts and virtual machines. Pricing for an SMB version with limited host and virtual machine support, as well as a service provider version with per-use pricing, will be unveiled later, he said.
