Thread: Multi RAID with SSD config for build server


we have new g7 2 x5680 3.3ghz i7's , 48 gb ram. question is, how config storage max benefit ubuntu build server.

came 2 raid cards:

p410i max of 8 devices - not fastest controller
p812 max of 8 devices - fast controller

have 14 disks , 2 ssd populate way want.

what's best config build server?

i'm puzzled how configure raid controllers maximum benefit.

i'm thinking should put 1 ssh on each controller, configure raid 7 disks on each controller linux sees 2 raid vols, , 2 ssd.
let me use flashcache create 2 ssd cached volumes.

eg:
flashcache_load cachedev /dev/sdc /dev/sdb
load existing cache on /dev/sdc, calling flashcache volume cachedev.

sdc ssd , sdb raid vol.

then, use lvm aggregate these 1 vg.

or, use 2 ssds in raid os , aggregate other 2 raids build storage?

or?

there lot of options on how set up. i'd appreciate suggestions.
