Using MPIO with multiple subnets

When you are using multiple subnets in a Multi-Site SAN, the HP LeftHand 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 LeftHand 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 SAN/iQ.
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.
