34 Intel Storage System SSR212PP User Guide
Revision 1.0
PRELIMINARY
Management port IP addresses should match the corporate network scheme.
Advantages
Low-cost storage for up to ten servers.
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
(Multiple-Initiator Servers)
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
SSR212PP-Series systems do not support management input/output.
