MPIO Deployment Guide.
11. If you have multiple NICs, repeat steps 1 through 10 for the additional NICs.
Using MPIO with multiple subnets
When you are using multiple subnets in a Multi-Site SAN, the HP StoreVirtual DSM for Microsoft
MPIO or Microsoft DSM will only build I/O paths to the storage systems that are in the same subnet
as the application server. See the HP StoreVirtual Storage DSM for MPIO Deployment Guide for
more information about MPIO.
When using VMware ESX 4 or higher and its native MPIO in a Multi-Site SAN, you cannot configure
more than one subnet and VIP. Multiple paths cannot be routed across subnets by the ESX/ESXi
4 initiator. With VMware vSphere, the preferred configuration is a single subnet and with vCenter
servers assigned to sites in LeftHand OS.
Configuring sites and managers to achieve optimal high availability and
redundancy
Several recommended site configurations can be used with the Multi-Site SAN software. These
configurations provide varying levels of availability and redundancy. Table 2 (page 13) shows
the recommended configurations. Select the one that best matches your environment.
