iSCSI Storage
Internet SCSI (iSCSI) is an industry standard developed to enable transmission of iSCSI
block storage commands and data over an existing IP network by using the TCP/IP
protocol. The encapsulated iSCSI commands and data can be transmitted over a local area
network (LAN) or a wide area network (WAN). As with traditional iSCSI, an iSCSI storage
solution requires at least one “initiator” residing on the client computer and at least one
“target” residing on the storage server.

Once the connection is established between the iSCSI initiator and the iSCSI target, the
operating system on the iSCSI initiator sees the storage as a local storage device that can
be formatted, read, and written in the usual manner.

Your WD My Cloud EX4 allows you to create and manage iSCSI targets. The iSCSI target
provides storage, similar to a local hard disk drive, but is accessed over a network rather
than locally. The iSCSI target is protected by the underlying RAID structure of the WD My
Cloud EX4 server.
