This white paper addresses the performance needs of data replication for disaster recovery, and the common barriers to achieving success. It also addresses the dramatic performance gains that can be achieved by combining the F5 WANJet application acceleration solution with the EMC Symmetrix Remote Data Facility® (SRDF®) family of remote storage replication solutions. Finally, this paper details how the F5 WANJet is specifically designed to optimize SRDF traffic and how storage managers can achieve 5 to 10x performance improvements in SRDF replication, significantly reducing bandwidth requirements and lowering IT costs.
