Chapter 1 Introduction iSCSI iSCSI Compatible Hard Drive iSCSI (Internet Small Computer System Interface) is a standard to transmit data on an Ethernet network by encapsulating SCSI commands in TCP/IP protocol. Once the iSCSI drive is connected to the network by Ethernet cables, the drive is recognized as a local drive by computers or servers on the network. TeraStation Network PC PC PC PC Server This illustration shows a TS-IXL TeraStation. The rackmount TS-RIXL is functionally identical.
Differences between NAS and iSCSI iSCSI A server creates shared folders on the iSCSI drive, and computers can then access the created folders on the servers. • Can be used as a local drive from Windows Server and accessed via the server by client computers. • All standard Windows features such as Access Restrictions with Active Directory can be used on iSCSI drives. • Database software that requires special formatting can be used with iSCSI drives.
Install the Microsoft iSCSI Software Initiator Windows XP, Windows 2000, Windows Server 2003, Windows 2000 Server Install Microsoft iSCSI Software Initiator first. Before using iSCSI equipment with Windows XP, 2000, Server 2003, or 2000 Server, download and install Microsoft iSCSI Software Initiator. 1. Visit to Microsoft's web site (www.microsoft.com). 2. Search for Microsoft iSCSI Software Initiator. 3. Download the latest version of the Microsoft iSCSI Software Initiator. 4.
Setup Notes: • If there is a DHCP server in the network, the TeraStation will get an IP address from it automatically. • Running the TeraNavigator software will automatically assign an unused IP address to a TeraStation. • TeraNavigator can only automatically configure one unit at a time. To reconfigure a TeraStation with TeraNavigator after its initial installation, initialize the TeraStation first. • If no DHCP server is available and TeraNavigator is not run, a random IP address of the form 169.254.xxx.
