Book description

IBM® has announced native Internet Protocol (IP) replication using Bridgeworks SANSlide technology with its IBM System Storage® SAN Volume Controller (SVC), IBM Storwize® V7000, IBM Storwize V5000 and Storwize V3700 virtualized storage systems.

This combination of SANSlide and the SVC/Storwize family provides a powerful solution for clients who require efficient, IP-based replication over long distances.

This certification gives SVC/Storwize clients a fully supported, transparent technology that includes unmatched levels of performance and reliability. With the SANSlide protocol acceleration technology, it is now possible to replicate data across continents in a cost-efficient way, with little or no loss in performance. At the same time, bandwidth usage can improve to over 95%, rather than the 1% - 5% normally achieved in long-distance IP networks.
This IBM Redpaper™ publication shows the steps required to implement this solution efficiently and speedily.
