hi all. thanks for the great feedback provided in the recent past. in the past i've based hardware purchases for small customers on the illumos HCL. i've mostly met with success, but have had issues with firmware and such even on supermicro motherboards.so for this latest small kvm project i started at: https://wiki.smartos.org/display/DOC/Hardware+Requirements which led me here: http://www.listbox.com/member/archive/184463/2013/02/sort/time_rev/page/1/entry/5:161/20130218134633:82C0ABBC-79FB-11E2-B214-A90A0365DAE4/ at first this seemed like exactly what i needed. but i'm finding that the hardware in question is getting tough to find, and is of course a bit dated. so i did the best i could and moved on to find what joyent uses in their own datacenter: http://eng.joyent.com/manufacturing/bom.html these machines are of course way overkill (and overpriced) for small deployments, though the documentation is great. so my questions are: 1) is there an updated version of the post found on listbox suitable for small installations?
It really depends what you call a "small installation". For example, I have compute nodes dedicated to zones with a small (single mirror) SSD pool and dedicated to KVMs with a spinning rust+SSD logs pool. Both could be considered small or overkill!
2) which of the joyent top level systems found on their engineering docs page would be the smartest to start from, to scale down to my needs/budget?
My approach here was to use single CPU Supermico X9 (the newer X10 boards should also work) boards with 10GE on board. If you need more drives than there are SATA ports, bung in an LSI2008 card. If your "small installation" doesn't need a redundant PSU, use an off the shelf mini-tower case.
3) i keep seeing "don't use SATA!" but see STEC SATA MLC SSD drives listed in the joyent builds. what do i really need, as far as SSD SLOG, for a small kvm system? i fully expect to see Samsung listed there in the near future. :)
SATA is fine as long as you aren't using SAS expanders. I use Intel 3700 or the newer 3710 drives for logs, power fail protection is important.
