Datrium 3.0 – Surviving all Host SSD failures!

0

I recently wrote about the new Datrium 3.0 release with blogs here and here, including the support for Red Hat Virtualization and mind-boggling performance numbers. However, during my writing, I forgot to include a new and critical feature that adds enhanced resiliency to the platform and protect the applications even is the last local flash device fails.

Peer Cache Mode

In DVX, we hold all data in use on flash on the host. Moreover, we guide customers to size host flash to hold all data for the VMDKs. With always-on dedupe/compression for host flash as well, this is feasible – with just 2TB flash on each host and 3X-5X data reduction you can have 6-10TB of effective flash. (DVX supports up to 16TB of raw flash on each host). Experience proves this is in fact what our customers do: by and large, our customers configure sufficient flash on the host and get close to 100% hit rate on the host flash.
