Sample IP addresses
Port | IP address | Subnet mask | Gateway |
Storage Processor A iSCSI port 0 | 172.31.1.150 | 255.255.255.0 | 0.0.0.0 |
Storage Processor A iSCSI port 1 | 172.31.2.150 | 255.255.255.0 | 0.0.0.0 |
Server 1 iSCSI NIC/HBA 1 | 172.31.1.101 | 255.255.255.0 | 0.0.0.0 |
Server 1 iSCSI NIC/HBA 2 | 172.31.2.101 | 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 |
Server 2 iSCSI NIC/HBA 2 | 172.31.2.102 | 255.255.255.0 | 0.0.0.0 |
Continue for up to 10 servers . . .
For additional throughput, add NICs or iSCSI HBAs to the configuration.
Management port IP addresses should match the corporate network scheme.
Advantages
Connection to multiple servers maximizes the use of the storage system s capabilities.
A dedicated iSCSI LAN avoids network contention with your corporate LAN, and reduces security risks.
Connection to each SP port from both servers provides redundant data paths in case one path fails.
Disadvantages
No load balancing.
SSR212PP2i Connected to a Dedicated iSCSI Network
Figure 12 shows an SSR212PP2i with up to ten servers. Each server has a single iSCSI initiator, and is connected with a single Ethernet switch, dedicated for iSCSI traffic, to the storage system s four iSCSI data ports. This represents the most common SSR212PP2i configuration.
