iSCSI is a protocol used to transport SCSI commands over a TCP/IP network. In an iSCSI environment, the client machine (in this case, an ESXi host) uses iSCSI initiators (hardware/software) to connect to iSCSI targets on an iSCSI storage system (array).
In this recipe, we will learn how to configure and connect to the array using the most widely used type: the software iSCSI initiator.
