Advantages

You can easily migrate this low-cost storage for a single server to a switched environment.

The dedicated iSCSI path ensures maximum throughput from the host to the storage system.

The dedicated path provides inherent security.

Disadvantages

Since only one server can connect to the storage system, this configuration does not take full advantage of the SSR212PPi s connectivity capabilities.

While this configuration provides port failover and load balancing, it does not allow SP failover.
