Hi people,

I was wondering if anyone had any I/O benchmark results for striped disk sets on
SGI boxes, either for just the striped disks, or relative to single disk
partitions. I'm looking for something that'll give me an idea of maximum and
expected real-world throughput, and a relative measure of increase/decrease in
performance with respect to individual disks.

Also, I know that the maximum partition size is 8GB, but what happens if I want
two partitions: one consisting of 5 1.6GB striped disks, and the other consisting
of 4 of the same. Is there any problem with this? What performance penalties, if
any, are there?

Thanks in anticipation,

Shawn
