Intel Storage System SSR212PP User Guide 19
PRELIMINARY
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.
