NAS Block Level Replication NAS Block level replication is based on the snapshot technology in the PowerVault NX3500 file system. Replication is volume based and can be used to replicate volumes on the same PowerVault NX3500 system (see Figure 7-1) or a volume on another PowerVault NX3500 system (see Figure 7-2). When replicating a volume to another PowerVault NX3500 system, the other system must be setup as a replication partner. Once a partner relationship is established, replication is bi-directional. One system could hold target volumes for the other system as well as source volumes to replicate to that other system. A replication policy can be setup to run on various schedules as well as on demand. All system configurations (user quotas, snapshot policy, and so on) are stored on each volume. When a volume is replicated, the target volume holds identical information. When removing a replication policy, an option is provided for transferring the volume configuration. Figure 7-1.

Protecting Data on PowerVault NX3500
NAS Block Level Replication
NAS Block level replication is based on the snapshot technology in the
PowerVault NX3500 file system.
Replication is volume based and can be used to replicate volumes on the
same PowerVault NX3500 system (see Figure 7-1) or a volume on another
PowerVault NX3500 system (see Figure 7-2). When replicating a volume to
another PowerVault NX3500 system, the other system must be setup as a
replication partner.
Once a partner relationship is established, replication is bi-directional. One
system could hold target volumes for the other system as well as source
volumes to replicate to that other system.
A replication policy can be setup to run on various schedules as well as on
demand. All system configurations (user quotas, snapshot policy, and so on)
are stored on each volume. When a volume is replicated, the target volume
holds identical information. When removing a replication policy, an option is
provided for transferring the volume configuration.
