I will defer to other vendors to comment on their own solutions, but the unique advantages of PernixData FVP software are:
· Clustered platform compatible with all VMware operations: PernixData FVP uses patent-pending Flash Cluster™ technology to enable any host to remotely access the flash device(s) on any other host in the cluster. This technology enables PernixData FVP to seamlessly support all VMware operations and products, such as vMotion, DRS, HA, Snapshot, VDP, Site Recovery Manager™, Horizon View™ and vCloud Director®. Live migrations and distributed resource management functions continue to operate transparently with PernixData FVP, with no changes to workflows and no hits to application, network or storage performance.
· Full read and write acceleration with fault tolerance: PernixData FVP supports full read and write (write through / write back) acceleration for maximum performance across all virtual applications. Writes are replicated across clustered hosts to ensure complete fault tolerance.
· Seamless deployment: FVP is installed inside the hypervisor kernel, not as a VM. This increases performance and fault tolerance, and ensures seamless integration - i.e no changes (or reboots) are required to VMs, servers or primary storage.
