Management port IP addresses should match the corporate network scheme.
Advantages
Improved security: System management requires a connection to the private network.
Adding NICs to the configuration increases throughput.
Connection to multiple servers maximizes use of the storage system s capabilities.
A dedicated iSCSI LAN avoids network contention with your corporate LAN and reduces security risks.
Disadvantages
Limited failover capability since the single initiator and single switch provide only one path from a server to the iSCSI Ethernet switch.
Reduced access for remote management: To perform management tasks, you must be connected to a host on the private network.
One storage processor does not allow for failover in case of SP failure.
SSR212PPi Connected to a Dedicated iSCSI/Management Network
Figure 15 shows an SSR212PPi with up to ten servers. Each server has two iSCSI initiators, and is connected with Ethernet switches (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
