I have a 320-2x card I wanted to use with the X4100, except it doesn't fit the low-profile slot that it has. So I tried it in a Dell 1425SC server... it reports random failures at different times on different disks on two different Dell powervault arrays which otherwise work flawlessly with an Adaptec 2230SLP card. If I run the 320-2X in Ultra 160 mode it has no complaints but that is stupid.... Of course everyone points the finger at everyone else... and I'm stuck in the middle with a bunch of expensive crap that won't work together. Anyhow.... I just (literally 15 minutes ago) got an IBM e326m evaluation unit. Watch for results shortly on that... I hope the 320-2x works fine with this box. > Doesn't the Sun use a Tyan board? It is based on a Tyan design, but significantly modified. The X4100 (and other X series) has no internal cables. Everything is plugged together more or less directly. There is one small flat 4" long ribbon cable hooking up something, but that's it. It is absolutely amazingly engineered. They also seem to have better QC than the OEM boards. However, the BIOS comes configured stupidly -- you have to turn on some options to make it bypass the BIOS 4GB hole, etc. Why not just do that by default?!?!?!!?!?!?!?!?!?
