Flash caching package supplier PernixData has upgraded its FVP product to incorporate RAM compression and therefore the ability to dump workloads mismated to solid state acceleration to SAN or NAS shared storage.
The upgrade – that takes FVP to version two.5 – can offer customers up to a 4x capability boost once victimization RAM as a cache, same PernixData selling vice-president Jeff Aaron, and may be used for all kinds of work.
PernixData FVP is one in every of variety of flash caching package merchandise. It runs on the VMware hypervisor, intercepts info writes and routes them to native host-based flash storage or RAM. That hot information is then out there to applications, with very fast access, whereas information is additionally written to the storage array.

The new feature on PernixData FVP – referred to as DFTM-Z – provides compression to RAM. It permits customers a lot of scope to use on-board memory as cache wherever antecedently they’ll have shied far from it, as a result of there wasn’t spare capability on host RAM to carry necessary datasets. It offers customers the choice to use RAM rather than flash, that additionally provides low latency however not as fast access as motherboard-mounted RAM.
PernixData has additionally side Intelligent I/O identification. This identifies workloads and sends those mismated to caching on to shared storage SAN or NAS arrays. this permits PernixData caching to be directed solely at the datasets that may get pleasure from I/O acceleration.
FVP creates a kind of write-back cache, wherever information is acknowledged to the host before it’s written to permanent storage. this may risk information loss in cases wherever a server fails however, with PernixData FVP, customers will specify that information is written to quite one cache to mitigate against host failure
