iSCSI - Internet Small Computer Systems Interface

The Internet Small Computer Systems Interface or iSCSI, is an end-to-end protocol for transporting storage I/O block data over an IP network. iSCSI encapsulates SCSI commands within TCP/IP. This allows iSCSI to be built on two of the most widely used protocols from the storage and networking worlds. The protocol is used on servers (initiators), storage devices (targets), and protocol transfer gateway devices. iSCSI uses standard Ethernet switches and routers to move the data from server to storage. It also enables IP and Ethernet infrastructure to be used for expanding access to SAN storage and extending SAN connectivity across any distance. The technology is based on SCSI commands used in storage traffic today and IP protocols for networking.

Advantages of iSCSI SANs:

• Familiar network technology and management - Reduces training and staff costs
• Proven transport infrastructure - Increases reliability
• Transition from 1 to 10-Gigabit Ethernet and Beyond - Protects investment with simplified performance upgrades
• Scalability over long distances - Enables remote data replication and disaster recovery
• Brings Ethernet economics to storage - Enables lower total cost of ownership
