How it works...
The number of paths made available for the iSCSI initiator will depend upon the type of iSCSI storage array.
With single portal arrays, the storage array exposes a single portal to be discovered by the source (initiator). Hence, the number of paths to such an array will depend on the number of VMkernel interfaces associated with the iSCSI initiator. The process of associating VMkernel interfaces with an iSCSI initiator is called port binding. We will learn more about port binding in the Configuring iSCSI multipathing using port binding section of this chapter. Arrays such as the HP's HPE StoreVirtual and Dell EqualLogic are examples of single portal arrays.
With multi-portal arrays, the storage array exposes multiple portals ...
