Compaq DL 580 - Peak PCI Bus Transfer Rate


From looking at the quickspecs for the DL580, it has 3 64-bit/100 MHz PCI-X buses.

I'm trying to determine if this server has sufficient IO capability to supply my needs (+300 MB/s continuous).

If I have one Fibre Channel HBA in each PCI-bus, (2 Gb FC), then is there a rule of thumb for practical usable IO bandwidth?

Each FC card can support 200 MB/s, but I doubt that this server can actually drive that.

Links that describe the architecture and practical limits beyond the quick specs are also appreciated.
