Silver Peak and EMC SRDF/A Technical Paper

The EMC Symmetrix Remote Data Facility / Asynchronous (SRDF/A) is a key component for disaster recovery with EMC Symmetrix storage arrays. SRDF/A provides the technology necessary to replicate large amounts of data between geographically separated data centers. SRDF/A throughput can be severely limited by problems with the WAN connection between the primary and secondary data centers. Limited bandwidth, latency, dropped packet, and out-of-order packets all reduce SRDF/A throughput, causing missed recovery point objectives (RPO) and failed replication.
