Intel SSR212PP manual This configuration incurs the cost of a second switch

Using two storage processors improves overall storage system performance.

Connection to each SP port from both servers provides redundant data paths in case one path fails.

Disadvantages

This configuration incurs the cost of a second switch.

SSR212PPi Connected to a Dedicated iSCSI/Management Network (Single-Initiator Server)

Figure 14 shows an SSR212PPi with up to ten servers. Each server has a single iSCSI initiator, and is connected with a single Ethernet switch (used for management and iSCSI traffic) to the storage system s iSCSI data and management ports.

This configuration requires a NIC connection; iSCSI HBAs qualified on

SSR212PP-Series systems do not support management input/output.
