Management port IP addresses should match the corporate network scheme.

Advantages

You can easily migrate this low-cost storage for four servers to a switched environment.

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

The dedicated paths provide inherent security.

Disadvantages

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

SSR212PP2i Directly Connected to Four Servers

Figure 9 shows four servers, each with an iSCSI initiator directly cabled to an SSR212PP2i iSCSI data port.
