<div dir="ltr">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. <div><br>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.</div><div><br></div><div>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 ? </div><div><br></div><div>Matt</div></div>
