Re: Tyan Thunder MB for postgres server

I've used LSI/MegaRAID controllers with the 2600 series servers with no
problems whatsoever in terms of performance.  With battery backed cache
the machine never went above 0.05 load factor in production, and could
handle pgbench with 300 to 600 tps under various settings.  Loading a 10
gig data set with fks and indexes took about 5 or 6 minutes.
