Using the P4000 DSM for MPIO with multiple NICs

The P4000 DSM for MPIO supports connecting multiple NICs in the application server to the SAN.
Configuring with multiple NICs improves fault-tolerant physical network connections in the server, as
illustrated in Figure

Using the P4000 DSM for MPIO in a Multi-Site SAN

The P4000 DSM for MPIO can be used in a Multi-Site SAN with one or more subnets. In this
configuration, the P4000 DSM for MPIO will only build I/O paths to the storage systems that are in
the same subnet as the application server. Alternatively, you can assign an application server to a
site. Application servers assigned to a site connect only to storage systems in the same site. Both of
these configurations permit higher performance and lower network utilization by not sending I/Os
across the WAN link.
