The arbitrated loop topology requires the KGPSA-CA adapter with V3.03 (or later) firmware and Version 5.8 or later
of the SRM console.
b
The KGPSA-BC/CA PCI-to-Fibre Channel adapters are only supported on the DWLPB PCIA option; they are not
supported on the DWLPA.
c
The 8200, 8400, GS60, GS60E, and GS140 AlphaServers support up to 63 KGPSAs in a standalone configuration.
d
The 8200, 8400, GS60, GS60E, and GS140 AlphaServers support up to 32 KGPSAs in a cluster configuration.
e
The GS80, GS160, and GS320 systems support only the KGPSA-CA Fibre Channel host bus adapter.
The following requirements and restrictions apply to the use of Fibre
Channel with TruCluster Server Version 5.1A:
• The HSG60 and HSG80 require Array Control Software (ACS) Version
8.5 or later.
• Eight member systems may be connected to common storage over Fibre
Channel in a fabric (switch) configuration. A maximum of two member
systems is supported in arbitrated loop configurations.
• The Fibre Channel RAID Array 8000 (RA8000) midrange departmental
storage subsystem and Fibre Channel Enterprise Storage Array 12000
(ESA12000) house two HSG80 dual-channel controllers. There are
provisions for six UltraSCSI channels. A maximum of 72 disks is
supported.
• TheStorageWorks Modular Array 6000 (MA6000) supports
dual-redundant HSG60 controllers and 1-inch universal drives.
• The StorageWorks Modular Array 8000 (MA8000) and Enterprise
Modular Array 12000 (EMA12000) support dual redundant HSG80
controllers and 1-inch universal drives.
• The HSG60 or HSG80 Fibre Channel array controller support only disk
devices.
• The only supported Fibre Channel adapters are the KGPSA-BC and
KGPSA-CA PCI-to-Fibre Channel host bus adapters. The KGPSA-BC
adapter is supported in fabric configurations only; the KGPSA-CA
adapter is supported in either fabric or arbitrated loop configurations.
• 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 only supported Fibre Channel hub is the 7-port DS-SWXHB-07. The
DS-SWXHB-07 has clock and data recovery on each port. It also features
