A dozen or more. Zero fan failures. 1 bad card, it came bad. > Can you say a bit more about the likely problems with the CLI ? The MegaCLI interface is the single most difficult user interface I've ever used. Non-obvious and difficult syntax, google it.

Older ones had a bad rep for performance but apparently their newer ones can be pretty darned good. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
