aThe 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.
