If you're running linux and thus stuck with the command line on the LSI, I'd recommend anything else. MegaRAID is the hardest RAID control software to use I've ever seen. If you can spring for the money, get the Areca 1680: http://www.newegg.com/Product/Product.aspx?Item=N82E16816151023 Be sure and get the battery unit for it. You can configure it from an external ethernet connector very easily, and the performance is outstandingly good.
Thanks. I took a look at Areca. The fan on the controller board is a big warning signal for me (those fans are in my experience the single most unreliable component ever used in computers). Can you say a bit more about the likely problems with the CLI ? I'm thinking that I configure the card once, and copy the config to all the other boxes, so even if it's as obscure as Cisco IOS, how bad can it be ? Is the concern more with things like a rebuild; monitoring for drive failures -- that kind of constant management task ? How about Adaptec on Linux ? The supercapacitor and NAND flash idea looks like a good one, provided the firmware doesn't have bugs (true with any write back controller though). -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
