Cisco SN 5420 Storage RouterExtending Your Storage Network with iSCSI
The Cisco SN 5420 Storage Router implements the Internet Small Computer Systems Interface (iSCSI) protocol to extend access of your Fibre Channel fabric and attached storage devices to IP servers. iSCSI combines the benefits of the TCP/IP protocol suite with SCSI, the universal standard for storage access. By utilizing iSCSI, the Cisco SN 5420 extends your Fibre Channel storage network to lower-priced/lower-performance servers in your data center and departmental servers located throughout your campus and enterprise. With the Cisco SN 5420, you can access your Fibre Channel storage area network (SAN) from anywhere on an IP network as easily as accessing direct-attached storage. By taking advantage of the cost advantages of 10/100 Ethernet networks or the performance advantages of Gigabit Ethernet, the Cisco SN 5420 Storage Router can connect servers to your shared Fibre Channel storage pool that would have previously been cost-prohibitive. The Cisco SN 5420 provides other advanced features, including network boot, which allows servers to be booted from an external storage device across an iSCSI network.
