Executive Summary
A new challenge faces IT professionals, dubbed the corporate
“extrastructure.” This includes devices and technologies outside
the IT department’s direct control, but are vital to the proper
operation of dispersed SANs and data resources. For example,
most corporations rely on third-party vendors for the bandwidth
and connectivity technology outside of the brick-and-mortar
confines. Since implementing a private global WAN would be cost
prohibitive, the company needs to bridge data centers without
sacrificing the benefits of a single-site operation.

prohibitive, the company needs to bridge data centers without
sacrificing the benefits of a single-site operation.
The best way to mitigate the limitations of a decentralized data
environment is to create a core-to-core bridging strategy using
standard, proven technologies. Core-to-core bridging is the
QLogic term for linking the core networks between data centers.
Data center switches, such as the SANbox 9200, can access
remote SAN islands with the proper deployment of gateway
routers. The SANbox 6142 Intelligent Storage Router can bridge
core switches across the WAN with fast and efficient Layer 3
routing. The routing can even be easily implemented across core
switching technologies from other vendors, for example Brocade
and Cisco.

Mission critical applications, such as data migration, replication,
and disaster recovery, can now be integrated across multiple
sites for better utilization, higher levels of protection, and faster
recovery times.
