not if one disk and its mirror dies. Of course, out of the 8 disks, the probability of two disks which are mirrors of each other dying is lower than the probability of death of two disks which are not mirror of each other. But Robinet seems to be right.

Got the card, put it in after the fingernail polish and kept getting a reboot. 4 hours later I found out the solution. May apply to MANY others in same boot loop.

Boot with the BBU unplugged then plug it in once it posts.

Works like a charm now.

And you have to do this every time you reboot, right?

ouch, what a hassle...

if there isnt a solution, maybe cut the red wire in the battery, and hook it up to a dipole switch?

At some point "buy a compatible motherboard" becomes a better solution.

couple snips and some electricians tape costs a lot less than a new mobo

for a system drive, getting a couple of low latency drives like 4 WD Raptors, 36GB and RAID0ing them is a good plan for a system drive. Then you still have 4 slots left for a RAID5 volume, something like 4 WDC 640's or even 4x1TB caviar blacks, or spinpoint F1's, or 7200.12's. That way youve got 3TB of storage.

You would lose some speed but still gain quite a bit of performance over a single drive by getting 2x 150GB VR's or 2x 74GB raptors or even 4 of these, it all depends on your budget.

You can expect most of these solutions for RAID0 as your system drive to double, triple, or even quadruple your throughput over a single drive (to an extent).

Just a reminder to all... the PERC 6/i does not support SATA 1.5Gb/s. This means the Raptors are not supported.
Once again...
