Managing iSCSI Storage on the WD Sentinel Server

iSCSI Overview

Internet SCSI (iSCSI) is an industry standard developed to enable transmission of SCSI block storage commands and data over an existing IP network by using the TCP/IP protocol. The encapsulated SCSI commands and data can be transmitted over a local area network (LAN) or a wide area network (WAN). As with traditional SCSI, 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 Sentinel server 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 Sentinel server.

iSCSI Roles

Initiator: A client computer that accesses storage devices using SCSI commands over an IP network.

Target: A network-attached storage device that provides access to logical disks (which can be created on the WD Sentinel server).
