With the Microsoft iSCSI Software Target in Windows Storage Server 2008, you can create 

and manage iSCSI targets, create and manage virtual disks for storage, and implement backup 

and recovery support by using snapshots.

The Microsoft iSCSI Software Target is pre installed and pre configured on all Bosch DLA 

models. If it is not installed or provided together with your storage appliance, contact your 

storage appliance manufacturer for information about acquiring the Microsoft iSCSI Software 

Target.

Several protocols, such as ATA (SATA) and SCSI (SAS), are available for enabling a disk 

controller to communicate with disk drives. These protocols are predefined standards that 

determine how commands, such as read and write requests, are packaged and sent between 

the controller and disk drive. The iSCSI protocol extends the SCSI standards by encapsulating 

SCSI commands in TCP/IP packets. These commands are sent over a TCP/IP network, which 

enables servers to access storage on a storage area network (SAN). This facilitates 

implementation and centralized management of consolidated storage, including centralized 

backup and remote system recovery.

In an iSCSI network, there are three components:

–

The iSCSI target provides storage, similar to the disk drives of locally attached storage, but 

accessed over a network instead of locally. This functionality is provided in Windows Storage 

Server 2008 by the Microsoft iSCSI Software Target.

–

The iSCSI initiator is sometimes referred to as the client. The iSCSI target provides the 

storage to the iSCSI initiator, which acts as a disk controller for the disks that are hosted by 

the target.

–

This is an Internet Protocol (IP)-based network that connects the iSCSI target to the iSCSI 

initiator. The storage fabric is typically a gigabit local area network (LAN).

The Microsoft iSCSI Software Target package comprises three components:

–

Microsoft iSCSI Software Target – This component lets you create and manage virtual 

disks, create and manage iSCSI targets, and provide backup and recovery of iSCSI 

targets through snapshots.

–

Volume Shadow Copy Service (VSS) Hardware Provider – The VSS Hardware Provider is 

installed on the initiator computer and works with the VSS service to provide application 

consistent snapshots of iSCSI virtual disks on the computer that runs the Microsoft iSCSI 

Software Target.

–

Virtual Disk Service (VDS) Hardware Provider – The VDS Hardware Provider is installed 

on an initiator computer and lets VDS-aware applications manage virtual disks on a 

storage appliance running the Microsoft iSCSI Software Target.
