Intel SSR212PP manual Environment and Configurability

You can connect up to four iSCSI HBAs or 4 NIC initiators (2 two-port NICs or 4 one-port NICs) in a server to one SSR212PP2i storage system. SSR212PPi systems support connection to 4 iSCSI HBAs 1 two-port NIC, or 2 one-port NICs.

You cannot use both iSCSI HBAs and NICs in a single server.

Separate servers with HBAs and servers with NICs can connect to the same storage system.

Environment and Configurability

A single host cannot attach to an EMC CLARiiON CX-series and an SSR212PP- Series iSCSI storage system at the same time.

For proper traffic routing in an environment that uses physically separated networks, each network must use a unique sub-network address.

This rule applies to both directly-connected configurations and those that use dedicated subnets for the data paths.

When using multiple NICs in a server (host), each card should be on a different subnet. The default Microsoft iSCSI Initiator configuration ignores additional cards on the same subnet, which require use of the Advanced Log On procedure.

The Cisco Linux iSCSI driver does not support multiple NICs/HBAs on the same subnet. Storage systems connected to Linux servers must configure each storage-processor port on a different subnet.
