Do you have any benchmark numbers? What benchmark do we care about here? We've tested various configurations and the I/O rate scales linearly with the number of blades involved. On Linux with dual 2GHz processors, two GbE interfaces, and one shelf per interface -- to get the load balanced properly across CPUs -- we see 80-90 MB/s sustained read/write throughput. I'm vying for this (our only workhorse) box to do freebsd tests on the same hardware. Give me a benchmark to try and I'll spit out some numbers when I get the box (later this afternoon). Sam
