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
Server 1 iSCSI NIC/HBA 1	172.31.1.101	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 2 iSCSI NIC/HBA 1	172.31.2.102	255.255.255.0	0.0.0.0
Storage Processor B iSCSI port 0	172.31.3.150	255.255.255.0	0.0.0.0
Server 3 iSCSI NIC/HBA 1	172.31.3.103	255.255.255.0	0.0.0.0
Storage Processor B iSCSI port 1	172.31.4.150	255.255.255.0	0.0.0.0
Server 4 iSCSI NIC/HBA 1	172.31.4.104	255.255.255.0	0.0.0.0

Management port IP addresses should match the corporate network scheme.

Advantages

You can easily migrate this low-cost storage for four servers to a switched environment.

The dedicated iSCSI path ensures maximum throughput from host to storage system.

Takes maximum advantage of the SSR212PP2i connectivity capabilities.

The dedicated paths provide inherent security.

Disadvantages

Since there is only one path to the SSR212PP2i from each server, this configuration provides no failover or load balancing capabilities.

SSR212PPi Connected to a Dedicated iSCSI Network (Single-Initiator Servers)

Figure 10 shows an SSR212PPi 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 iSCSI data ports.
