Cluster topology

Server and Cluster Administration Guide for Hitachi NAS Platform

Part Number

Typically, the private management network connects cluster nodes and the QD, keeping cluster traffic off of the public data network, and isolating them from potential congestion due to heavy data access loads.

The high-speed cluster interconnect provides an additional, direct connection among the cluster nodes. This dedicated connection consists of dual redundant gigabit Ethernet links, and is reserved for clustering traffic and NVRAM mirroring.

Note: Setting up a cluster requires a license. Contact Customer Support to purchase a cluster license. Additionally, note that the maximum number of nodes available in the VSP N series or VSP Gx00 or VSP Fx00 with NAS modules is two. The NAS module hardware contains two nodes that are automatically clustered, and no license is required for their use.
