Hmmm. We use an MSA 1000 with Fibre Channel interconnects. No real complaints, although I was a little bit disappointed by the RAID controller's battery-backed write cache performance; tiny random writes are only about 3 times as fast with write caching enabled as with it disabled, I had (perhaps naively) hoped for more. Sequential scans from our main DB (on a 5-pair RAID 10 set with 15k RPM drives) get roughly 80MB/sec. Getting the redundant RAID controllers to fail over correctly on Linux was a big headache and required working the tech support phone all day until we finally got to the deep guru who knew the proper undocumented incantations. -- Mark Lewis On Thu, 2006-04-20 at 20:00 +0200, Mikael Carneholm wrote: > We're going to get one for evaluation next week (equipped with dual > 2Gbit HBA:s and 2x14 disks, iirc).
