Server 1 iSCSI NIC/HBA 1 172.31.1.101 255.255.255.0 0.0.0.0
Server 2 iSCSI NIC/HBA 1 172.31.1.102 255.255.255.0 0.0.0.0

Continue for up to 10 servers . . .
The above addresses are not valid for a Linux environment, in which each SP port
must be on a different subnet. A Linux host in this configuration could log in to
ports on SP A or SP B, but not both. Management port IP addresses should match
the corporate network scheme.
Advantages
Low-cost storage for up to ten servers.
Connection to multiple servers maximizes use of the storage system s capabilities.
Using a dedicated iSCSI LAN avoids network contention with your corporate LAN
and reduces security risks.
This configuration provides failover capabilities in the event of a storage processor
failure.
Using two storage processors improves overall storage system performance.
Disadvantages
This configuration has limited failover capability since the single initiator and single
switch provide only one path from a server to the iSCSI Ethernet switch.
