Hardware overview
Fibre channel (FC) switches
The HUS VM file module supports Fibre Channel switches that connect
servers to storage subsystems. Contact Hitachi Data Systems Support
Center for information about which Fibre Channel switches are supported.
External fast ethernet (10/100) or GigE switches
A standalone HUS VM file module can operate without an external Ethernet
switch, as long as it uses an internal SMU and there are less than three RAID
subsystems attached.
A standalone file module server requires an external Ethernet switch if there
are three or more RAID subsystems attached or if there are two RAID
subsystems attached and an external SMU is used. All cluster configurations
require an external Ethernet switch.
10 GbE (10 Gigabit Ethernet) switches (cluster configurations
only)
The HUS VM file module server supports 10 GbE switches that connect
multiple storage servers configured as a cluster. Contact your Hitachi Data
Systems representative for information about the 10 GbE switches that
have been qualified for use with the file module system, and to find out
about the availability of those switches.
Currently, the only 10 GbE switch that has been qualified is the Brocade
TurboIron 24X, a standalone 10Gbps Managed Layer 2 Ethernet switch with
eight ports. It is available through Hitachi Data Systems. Hitachi Data
Systems requires dual 10 GbE switches for redundancy. If one switch fails,
the cluster nodes remain connected through the second switch.
