The maximum number of drives behind an HSG80 (single or
dual-redundant pair) using three dual-bus Model 4254 disk
enclosures is 42.
The Model 4214R and Model 4254 disk enclosures support
only the new Compaq hot-pluggable wide-UltraSCSI low
voltage differential (LVD) disk drives.
For more information on configuring the MA8000/EMA12000, see the
Compaq StorageWorks Modular Array Configuration Guide.
• Only disk devices attached to the HSG60 or HSG80 Fibre Channel array
controller are supported with the TruCluster Server product.
• No tape devices are supported behind an HSG60 or HSG80 RAID array
controller.
• The only supported Fibre Channel adapters are the KGPSA-BC and
KGPSA-CA PCI-to-Fibre Channel host bus adapters.
• The KGPSA-BC/CA PCI-to-Fibre Channel adapters are only supported
on the DWLPB PCIA option; they are not supported on the DWLPA.
• A host is only allowed to have one KGPSA connected to each switch
or switch zone.
• The only Fibre Channel switches supported are the DS-DSGGA-AA/AB
8/16 port, DS-DSGGB-AA/AB 8/16 port, or DS-DSGGC-AA 8 port Fibre
Channel switches.
• The DSGGA and DSGGB Fibre Channel switches support both
shortwave (GBIC-SW) and longwave (GBIC-LW) GigaBit Interface
Converter (GBIC) modules. Seven of the eight DSGGC ports are fixed
shortwave optical transceivers. Only one DSGGC port is configured as a
removable GBIC. It may be shortwave or longwave.
The GBIC-SW module supports 50-micron, multimode fiber cables with
the standard subscriber connector (SC) connector in lengths up to 500
meters. The GBIC-LW supports 9-micron, single-mode fiber cables with
the SC connector in lengths up to 10 kilometers.
The KGPSA-BC/CA PCI-to-Fibre Channel host bus adapters and the
HSG60 and HSG80 RAID controller support the 50-micron Gigabit Link
Module (GLM) for fiber connections. Therefore, only the 50-micron
multimode fiber optical cable is supported between the KGPSA and
switch and the switch and HSG60 or HSG80 for cluster configurations.
You must install GBIC-SW GBICs in the DSGGA and DSGGB Fibre
Channel switches (or one DSGGC open port) for communication between
the switches and KGPSA or HSG60/HSG80.
