RE: Opteron HOWTO - #mysql Freenode
Over the last week I added in lots of comments pasted in from various places. I'd appreciate those running with Opteron and MySQL to have a close look at the WIKI and make any amendments/suggestions. http://hashmysql.org/index.php?title=Opteron_HOWTO My Opteron server will be here shortly and I'll do some performance testing on RAID5 (8 disks) versus RAID 10 (8 disks, 2 channels). I'll also do some performance tests with 128MB cache and 512MB cache on the SCSI card to let you know if that makes a difference. Best regards, Richard Dale.

Thats great news... I reconfigured one of our slaves from RAID5 to RAID1 and setup the controller as writeback and caching the stripes. I'm getting about 75% additional performance. I wanted to put the controller on additional channels but it turns out that I need a stupid proprietary cable from Dell to accomplish this. I'm not sure what benchmark I could see from using two channels then. My gut though in our config says that we won't see any performance increase since I'm not maxing out the IO on each channel (but I might be wrong). I'd love to see your numbers here. -- Use Rojo (RSS/Atom aggregator)! - visit http://rojo.com. See irc.freenode.net #rojo if you want to chat.
