Management port IP addresses should match the corporate network scheme.
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.
