I've use the Dell PERC 4DC and had VERY good performance from it. IT's
the late model U320 LSI MegaRAID and runs great. I do remember that the
2650 and few other Dells had the serverworks chipset in them that caused
a lot of context switches in heavy parallel load in a discussion on the
performance list. We weren't running heavy parallel, just a report
server with a dozen or so users, so it wasn't an issue for us.
Whatever the ultimate cause, I can't say. But I can say that I'm not planning to buy any more Dell servers for my database needs. Both my 2450 and 2650 basically suck at I/O load with any kind of concurrent access. I might as well be running IDE :-(
