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.
The dedicated paths provide inherent security.
Disadvantages
Since only two servers can connect to the storage system, this configuration does not
take full advantage of the SSR212PP2i s connectivity capabilities.
SSR212PP2i Directly Connected to Four Servers
Figure 9 shows four servers, each with an iSCSI initiator directly cabled to an
SSR212PP2i iSCSI data port.
