Overview
• Easy and inexpensive management — The PS Series storage array has
offers centralized storage which enables you to manage more storage
efficiently. You can use a simple setup utility to configure an array on the
network and create a PS Series group and a functioning iSCSI SAN. You
can easily manage automation of complex operations like RAID
configuration, disk sparing, data provisioning, and load balancing to ensure
effectively managing the SAN.
• Advanced management features — The PS Series comes standard with a
comprehensive set of features including automatic load balancing, virtual
volume management, space-efficient snapshots for instant backup and
restore, volume cloning for rapid server provisioning, multipath I/O
support, cluster support, and Auto-Replication capabilities delivering a
comprehensive disaster recovery solution.
Each array (member) in a group contributes disk space to the pool, which can
store the cluster quorum resource in addition to the data used by the cluster
applications. As needed, you allocate portions of the pool to volumes, specifying a
size, access controls, and other attributes. The PowerVault NX1950 storage
system sees each volume as a single device and each volume is automatically
load-balanced across multiple disks and group members as required.
Figure 1-2 shows a cluster configuration with a PS Series group as the shared
storage.
