a The KGPSA-BC/CA PCI-to-Fibre Channel adapters are only supported on the DWLPB PCIA option;
they are not supported on the DWLPA.
The following requirements and restrictions apply to the use of Fibre
Channel with the TruCluster Server:
• The HSG80 requires Array Control Software (ACS) Version 8.5.
• A maximum of four member systems is supported.
• The only supported Fibre Channel adapters are the KGPSA-BC and
KGPSA-CA PCI-to-Fibre Channel host bus adapters.
• The only Fibre Channel switches supported are the 8/16 Port DSGGA or
DSGGB Fibre Channel switches.
• The Fibre Channel switches support both shortwave (GBIC-SW) and
longwave (GBIC-LW) Giga Bit Interface Converter (GBIC) modules.
The GBIC-SW module supports 50-micron, multimode fibre cables with
the standard subscriber connector (SC connector) in lengths up to 500
meters. The GBIC-LW supports 9-micron, single-mode fibre cables with
the SC connector in lengths up to 10 kilometers.
The KGPSA-BC/CA PCI-to-Fibre Channel host bus adapters and the
HSG80 RAID controller support the 50-micron Gigabit Link Module
(GLM) for fibre connections. Therefore, only the 50-micron multimode
fibre optical cable is supported between the KGPSA and switch and the
switch and HSG80 for cluster configurations. You must install GBIC-SW
GBICs in the Fibre Channel switches for communication between the
switches and KGPSA or HSG80.
• A maximum of three cascaded switches is supported, with a maximum of
two hops between switches. The maximum hop length is 10 km longwave
single-mode or 500 meters via shortwave multimode Fibre Channel cable.
