the R100 is an 880 with a black faceplate. so, depending on how you create the raid groups and volumes, you should be able to get unclustered 880-ish performance.
for my R100, that means around 40 Mbyte/sec sustained writes; writes are limited by the speed of writing blocks to, and destaging from, the NVRAM card.
and around 125 Mbyte/sec on sustained reads, which seems to be limited to the CPU's ability to deal with the GigE cards.
YMMV. -skottie

What was the speed you were expecting? And what did you get? When writing to all (9) R100 volumes concurrently, I got to a max of 30Mbytes/Sec. That got the R100 to 100% cpu constant. (The source filers weren't that busy).

I'm working with a customer who just got an R-100 and the performance is much less than we expected.
I'm wondering what type of performance other people are experiencing with their R-100, or for that matter with other similar low-cost drive storage options.
If anyone has actually had time to run a benchmark that would be great.
