In an iSCSI network, there are three components:
- The Target is like classic direct-attached storage. A DAS device is a hard disk like ATA or SCSI disks. It offers the disks to the Initiator.
- The Initiator can be compared with a traditional disk controller. It uses the hard disks hosted by the Target.
- The TCP/IP network interconnects the Initiator and the Target. For performance, at a minimum, you should use a gigabit network between the Target and Initiator.
Since Microsoft does not offer its own iSCSI Target Software, for the purpose of this tip, I am using the Starwind iSCSI solution to illustrate how to set up iSCSI for Exchange Server 2003. You can download a trial version of Starwind from the Rocketdivision Web site.
Another option is WinTarget from String Bean Software, which I wrote about in an MSExchange.org article, Implementing iSCSI for Exchange Server 2003. (Microsoft acquired String Bean Software in March 2006.)
After downloading and installing the Starwind program, start the Starwind console and connect to the Localhost.

The default username and password is test. (You should, of course, change the password as soon as possible.)
SPTI stands for SCSI pass-through interface; it allows any physical storage device, such as local hard disk and CD-ROM, to be shared as iSCSI target. For our example, select SPTI device to create a new SPTI device that will then be accessible on Exchange Server 2003.

After selecting SPTI, choose the device you want to make accessible through iSCSI.

You have successfully created a new device named searchexchange. This device is now possible on the Exchange Server 2003 with the iSCSI Initiator installed.

Now it's time to install the Microsoft iSCSI Initiator on the Exchange 2003 server. You can use the Microsoft iSCSI Initiator 2.0.

Once you've downloaded the iSCSI Initiator, install it and reboot. Then start the ISCSI Initiator configuration in Control Panel, click Discovery and then Add to add the iSCSI Target.

Next, select Targets. You will see the published Targets on the iSCSI Target. Click Log On.

After connecting to the iSCSI Target, you can use the Disk Management console from Windows Server 2003 to create a new volume on your Windows 2003 server.
After creating and formatting the new volume, you can start Exchange System Manager and move the Exchange Server databases and/or transaction log files to the new volume.
