4.1 Open-iSCSI initiator setup with Dell EMC PowerVault ME4 Series
arrays
When planning an iSCSI network, isolate the iSCSI traffic from management traffic through the use of
separate switches and subnets. Failure to follow this best practice may result in compromised reliability or
performance.
When implementing multipathing with iSCSI storage, be certain none of the redundant iSCSI paths are
configured within the same subnet or on the same physical network as the management interface. If this
occurs, the iSCSI initiator will not be able to successfully establish a session over any iSCSI path on the
management network or subnet.
Multipath with dual subnets: In this configuration, the Front End iSCSI control ports on the Dell EMC
PowerVault ME4 Series storage are on two separate subnets. This option uses MPIO for multipathing.
This is the recommended option when high availability (HA) is required.
