With port binding enabled, a single vSwitch with two NICs can be configured so that each NIC is bound

to one vmkernel port. The two NICs, or vmkernel ports, should be on different subnets. Also, the two SPs

for a storage processor should be on different subnets, as shown in

Figure 12. No gateways should be

configured on the NICs or SP ports.

Multipathing and failover on ESX 3.x and ESX 2.x with CLARiiON

The CLARiiON storage system supports VMware ESX Server’s built-in failover mechanism; this

mechanism is available for ESX 3.x and 2.x servers, and provides failover but not active I/O-load

balancing.

PowerPath multipathing and failover software is not supported on VMware ESX 3.x and 2.x servers.

The native failover software provides a listing of the paths—whether active or passive—from VMware

ESX Server to the CLARiiON storage system. The exscfg-mpath command in ESX 3.x provides details

on all devices (Fibre Channel, iSCSI, and local) and the number of paths attached to that device. With
