Open Stack

Time once again to dredge this topic up and see what the wider operators
community thinks this time :) There were a fair amount of summit
submissions for Barcelona talking about converged and hyper-converged
infrastructure, it seems to be the topic de jour from vendors at the minute
despite feeling like we've been round this before with Nebula, Piston Cloud
etc.

Like a lot of others we run Ceph, and we absolutely don't converge our
storage and compute nodes for a variety of performance and management
related reasons. In our experience, the hardware and tuning characteristics
of both types of nodes are pretty different, in any kind of recovery
scenarios Ceph eats memory, and it feels like creating a SPOF.

Having said that, with pure SSD clusters becoming more common, some of
those issues may well be mitigated, so is anyone doing this in production
now ? If so, what does your hardware platform look like, and are there
issues with these kinds of architectures ?
