System overview
The system can contain a single file module (Hitachi NAS Platform), or
several file modules operating as a cluster. Clusters using more than two
Hitachi NAS Platforms typically include 2 x 10Gbps Ethernet switches (one
is required, but two are recommended for redundancy). For instructions on
how to implement a cluster configuration, refer to the Server and Cluster
Administration Guide.
Figure 1-3 Example Unified Storage VM file module configurations on page
1-9 shows two examples of file module system configurations including a
rack containing up to two NAS servers, two system management units
(SMUs), two fibre channel switches, and up to 32U of storage per rack,
depending on the number of servers and system management units
installed. The hardware section following the figure describes the individual
system components.
