Greybeards talk server DRAM IO caching with Peter Smith, Director, Product Management at Infinio

Welcome to our sixth episode. We once again dive into the technical end of the pool with  an in-depth discussion of DRAM based server side caching with Peter Smith, Director of Product Management at Infinio. Unlike PernixData (checkout Episode 2, with Satyam Vaghani, CTO PernixData) and others in the server side caching business, Infinio supplies VMware server side storage caching using DRAM for NFS VMDKs. It got a bit technical fairly fast in the podcast, sorry about that.

This months podcast comes in at a little over 40 minutes and was recorded on 20 February 2014. The overall sound quality is much better than Episode 5 but we are still working out some of the kinks, so bear with us.  

Peter comes from a number of different IT infrastructure and co-location services and brings a wealth of knowledge on IO caching within a VMware server environment. With all the DRAM supplied in ESX servers these days and the increasing compute power that’s now available, the time seems ripe to implement a deduplicated, DRAM cache for VMware IO.

Infinio clusters together segments of ESX DRAM, across nodes in a VMware cluster to supply an IO cache. The software installs across the VMware cluster non-disruptively (~ = Vmotion) and Infinio clusters can be expanded without operational impact.

There was some discussion on the odds of a (random) SHA-1 hash collisions happening in our lifetimes (as Greybeards our lifetimes may be shorter than yours). I tried to get Peter or Howard to give me commensurate odds on this happening but alas, no takers.
