Understanding iSCSI Technology
As a storage networking technology, iSCSI (Internet Small Computer System Interface) facilitates block-level access to data storage systems over a TCP/IP network. It is a cost-effective solution that allows organizations to use existing Ethernet networks to access storage systems, eliminating the need for dedicated storage networks. The iSCSI protocol encapsulates SCSI commands into TCP/IP packets and enables data transmission over long distances through standard network infrastructures.
One of the benefits of using iSCSI technology is its ability to support both local and remote data storage, providing administrators with the flexibility to manage data from a central location. iSCSI initiators are software components that enable servers to communicate with iSCSI targets. They send SCSI commands to the target to read or write data. The iSCSI target, on the other hand, is a server that provides access to storage devices over the network.
Another benefit of iSCSI technology is its ability to use existing Ethernet networks, which are ubiquitous in most organizations, to access storage systems. This eliminates the need for expensive, dedicated storage networks, which can be costly to implement and maintain. In addition, iSCSI technology is highly scalable and can be used to build large, complex storage networks that can accommodate the needs of any organization.
The Basics of iSCSI Technology
iSCSI stands for Internet Small Computer System Interface, which is a storage networking standard used to link data storage facilities. iSCSI uses TCP/IP protocol to communicate between iSCSI initiator and iSCSI target.
iSCSI technology makes it possible to use storage devices over a network instead of having to use them locally. An iSCSI initiator sends SCSI commands to an iSCSI target, which processes them and returns the appropriate response. This allows for centralized storage, which can be easily accessed by multiple servers or workstations.
Benefits of iSCSI technology include reduced costs, improved flexibility, and better utilization of storage resources. It enables administrators to create and manage storage devices using standard Ethernet networks, eliminating the need for dedicated storage networks.

Connecting to iSCSI Target from iSCSI Initiator on Windows Server 2008
iSCSI Initiator Configuration: To connect to the iSCSI target from an iSCSI initiator, the initiator must be configured with the target’s IP address, target name, and any required authentication information.
Connecting to the Target: Once the iSCSI initiator is configured, it can establish a connection to the target by sending a connection request to the target’s IP address. The target will respond with a connection confirmation and the initiator will be able to access the target’s resources.
Mapping iSCSI Targets: Once the connection is established, the initiator can map the iSCSI target to a local drive letter. This allows the initiator to access the target’s resources as if they were local disks.
Managing Multiple iSCSI Targets: Windows Server 2008 allows administrators to connect to and manage multiple iSCSI targets from a single iSCSI initiator. This can simplify storage management and allow for more efficient use of storage resources.
Disconnecting from iSCSI Target: To disconnect from the iSCSI target, the initiator can either disable the iSCSI session or log out of the iSCSI target. This will terminate the connection and release any resources being used by the initiator.
Discovering iSCSI Target on Windows Server 2008
iSCSI target discovery is the process of locating iSCSI targets on the network. Before connecting to an iSCSI target, the iSCSI initiator must discover it. There are two ways to discover an iSCSI target on Windows Server 2008: dynamic discovery and static discovery.
In dynamic discovery, the iSCSI initiator sends a broadcast request to all devices on the network, looking for iSCSI targets. The targets respond with their IP addresses, and the initiator can connect to them. This is the easiest way to discover targets, but it can be slow and inefficient.
In static discovery, the iSCSI initiator is configured with the specific IP address of the iSCSI target. This method is faster and more efficient than dynamic discovery, but it requires manual configuration of each target.
Windows Server 2008 also supports Multipath I/O (MPIO), which allows for redundant connections to the same iSCSI target for increased reliability and performance. With MPIO, multiple connections can be established to a single iSCSI target, and the initiator can load-balance I/O across these connections.
Connecting to iSCSI Target on Windows Server 2008
To connect to the iSCSI target on Windows Server 2008 from the iSCSI initiator, you need to follow the below steps:
