application requirements dictate the solutions that are deployed, FCIP is suitable for a large majority of remote data

mirroring applications. FCIP is ideal for wide area connectivity between two data centers over a WAN link of varying

speeds.

The integrated iSCSI capability is a low-cost host connectivity option leveraging an existing IP/Ethernet

infrastructure. The iSCSI technology helps to optimize the use of expensive storage and tape subsystems by fanning

the scope of the storage network to midrange and low-end servers in a cost-effective manner. This integration

represents the industry’s first Fibre Channel and IP storage integrated solution in a highly available director platform.

Low-end servers with departmental or workgroup applications can easily be integrated into the same storage

network fabric to provide easier access to corporate resources. Now workgroup applications are not tied to limited

storage capacity or suffer from downtime caused during capacity upgrades. In addition, performance is not

compromised, rather now delivered at a much lower cost. Furthermore, iSCSI provides centralized, shared tape

option, LAN-free, and server-less capable backup and recovery solutions for departmental or workgroup application.

It is clear that Cisco’s intelligent storage network feature set coupled with a focus on data center availability

requirements delivers a breadth of solutions unmatched in the industry today. Cisco’s products deliver enhanced

management features to address enterprise concerns of reducing downtime caused by unplanned outages as well as

planned upgrades. Technologies such as FCIP and iSCSI allow enterprises to reduce infrastructure costs while still

providing integrated management across the two technologies.
