Revision 1.0
PRELIMINARY
SSR212PP2i Connected to a Dedicated iSCSI Network (Multiple-
Initiator Servers)
Figure 13 shows an SSR212PP2i with up to ten servers. Each server has two iSCSI
initiators, and is connected with Ethernet switches (dedicated for iSCSI traffic) to the
storage system s four iSCSI data ports. This represents a secure and highly available
SSR212PP2i configuration.

Continue for up to 10 servers . . .
Management port IP addresses should match the corporate network scheme.
Advantages
Low-cost storage for up to ten servers.
Connection to multiple servers maximizes the use of the storage system s capabilities.
Using a dedicated iSCSI LAN avoids network contention with your corporate LAN
and reduces security risks
Failover capabilities in the event of a storage processor failure.
