I checked Xsan Admin for fiber traffic from my backup server. topped
out at 120MB/s for fiber backup through Qlogic to Scalar 24 lto3.

I'm trying to get a hold on where the bottleknecks in terms of
bandwidth. If your basic layout is going from RAID, through
cabling, to a switch, through more cabling, and then to the
machine, where is the bottlekneck? I'm not concerned with the Read/
Write speed of the RAID at the moment.
Someone correct me if I'm wrong. The actual throughput on the FC
controller on the XServe RAID is somewhere around 80MB/s? The
throughput on the FC cabling is theoretically 200MB/s? What about a
switch, say a QLogic SANbox 5200? What is the realistic throughput
for that (or a similar switch, or any switch)? How about the
throughput through the Apple FC card? PCI, PCI-X, PCIe versions of
their card? Are these throughput numbers even important?
Sorry for the basic questions. I've got some books about this stuff
on the way, but I figured I'd ask while I'm waiting.
Regards,
Aaron
