Good VM sizing post (originally for MSSQL, but a lot of it applies to everything you virtualize) I find that the single most telling memory usage stat is page faults (what MS calls hard faults now). Once you get rid of (most of) those, watching application/service latency while you vary vRAM will give you a better idea of what works best. Always start small.

Misogynist posted:The IBM stuff that we were having problems with was the Midrange Storage series (DS4800, DS5100) which is rebranded LSI with some IBM tweaks and parts fulfillment. On another subject: I'm trying to put together some hosts, and hitting an information wall: can I run a 8GB and a 4GB DIMM per channel (for 96GB totalon a 2socket box), or a 8GB and a 16GB DIMM per channel (for 192GB total) and still run them at 1.6ghz? Dell website says yes, but my rep checked with an Intel presales guy and he said 1.3ghz max? This is annoying because I'd rather not run all my hosts at 128GB (gently caress you VMware licensing).

Start low and watch application performance is the general rule of thumb. One question is why it needed to be P2V'ed instead of re-implemented as a VM. Rhymenoserous posted:It's not P2V'd, started fresh. evil_bunnY fucked around with this message at 17:33 on Mar 13, 2012 |

Beelzebubba9 posted:So my question is how would this be effected by vMotion in case of a host failure? I assume ram states are persisted in case of the failover, and the worst case is there might be a brief loss of synchronicity between all of the parts of the database. Is there anything I should be worried about other than that? Beelzebubba9 posted:Obviously you'd be compensated.

Also if your users are crazy scientists who need 128GB VMs it helps to imbalance the RAM across hosts.

Kachunkachunk posted:Slight corrections, I had to go read up on it since it's fuzzy. ESXi host swapping happens on the configured scratch partition, if needed. I think it should pick one by default now, but you can configure it. This is also the only way you will have some persistent logging past reboots. It'll be to a datastore, basically. That way when you start replicating, you can specify a non-stupid schedule for the swap data instead of keeping it near-synchro like the data you actually give a poo poo aobut.

I've said this before, but the first time your virtual environment saves your bacon/allows you to fix/upgrade hardware during business hours instead of when you could be boozing you'll stop thinking about the license costs.
