High-performance NAS Platform Rear View (Series 2000)
Note: For additional data protection, it is recommended to use an
external UPS to power the High-performance NAS Platform. Also, each of
the redundant power supplies in the High-performance NAS Platform and
in the storage subsystems should be operated from a different mains
power circuit in order to provide a degree of protection from mains power
supply failures. In the event that one circuit fails, the other will continue
to power the High-performance NAS Platform and the storage subsystem.
• Storage Subsystem(s)
A storage cabinet containing the High-performance NAS Platform can also hold
several storage enclosures. The maximum number of storage enclosures that can
be placed in an expansion cabinet is dependent on the model of storage
enclosures installed.
Subsystem Guide for more information on supported storage subsystems.
• Fibre Channel (FC) switches
The High-performance NAS Platform supports Fibre Channel switches that connect
multiple servers and storage subsystems.
Contact Hitachi Data Systems Technical Resource Center (TRC) for information
about which Fibre Channel switches are supported.
• 10 GbE (10 Gigabit Ethernet) switches (used in cluster configurations only)
The High-performance NAS Platform supports 10 GbE switches that connect
multiple servers when configuring a cluster.
Currently, the following 10 GbE switches have been qualified, and are available
through Hitachi Data Systems:
• Brocade EdgeIron 8X10G (formely from Foundry Networks), a standalone
10Gbps Managed Layer 2 Ethernet switch with eight ports. This switch
allows you to create a cluster with up to 8 nodes.
• SMC Networks SMC8708L2 TigerSwitch, a standalone 10Gbps Managed
Layer 2 Ethernet switch with eight ports. This switch allows you to create a
cluster with up to 8 nodes.
