For the Qlogic 2200F I am able to push 100 MB/s for
reads and writes using multiple threads to a filesystem
that is striped across mutliple host ports on the SAN. Backend RAID is a
Data Direct Networks SAN. For a single thread to a ext3 filesystem
and 2.4.18, I get about 70 MB/s for reads and writes.
I have no Iops/sec numbers.
