I have a 1u (6013p-8) Supermicro and a 2u (6023p-8), both with Adaptec Zero Channel U320 Raid cards. They hang solid and reliably under heavy loads (3 simultaneous "iozone -a" in different directorys. You can kill it under Linux or FreeBSD 4/5 this way. I've swapped discs, firmware for discs, and now taken the ZCR out and put a Megaraid 320/1 in there. Much slower and same lockup problem. If I had to guess, I'd point the finger at Supermicro (Latest BIOS on both, dropping to 40Mb/sec from U320 on the ZCR's makes no difference to stability). Apart from that, I really like them!
