Fibre-Host RAID Connections
The Fibre Channel standard allows for both copper and optical connections. Copper
cable is cheaper but limited to lengths of less than 30m (33 yards). Optical cables
can be used over longer distances and have been shown to be more reliable. Due to
the demands of high transfer rates, optical cables are preferred for 8/4Gbps fiber
connectivity. Optical cables are also less susceptible to EMI.
The following transceiver and cables have been tested and proven to be compatible
with your systems.
Infortrend’s part numbers for cables of different lengths are:

The Fibre host ports connect to Fibre Channel host adapters (HBA) that feature a
8Gbps transfer rate, SFP interface, and support for full-duplex transfer, best come
with a 64-bit/133MHz PCI-X or PCI-E interface. Please contact your vendor for a list
of the latest certified items.
WARNING
All Fibre cables are sensitive and must be handled with care. To avoid interference,
the cable routing path must be carefully planned and the cables must not be bent.
