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.

Redundant paths to the SSR212PP2i provide better failover capabilities. They sustain access to the storage system in the event of an iSCSI initiator, cable, or data port failure.

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

Disadvantages

Since only one server can connect to the storage system, this configuration does not take full advantage of the SSR212PP2i s connectivity capabilities.

A single server does not allow for expansion.

SSR212PP2i Directly Connected to Two Servers

Figure 8 shows two servers, each with two iSCSI initiators, directly cabled to the iSCSI data ports on an SSR212PP2i.
