VMware vCenter Site Recovery Manager 4.0 is a component of VMware Infrastructure that ensures a speedy and successful datacenter recovery by automating the recovery process and eliminating the complexity of managing and testing recovery plans. A new white paper, VMware vCenter Site Recovery Manager 4.0 Performance and Best Practices, is now available at

In this paper we discuss VMware vCenter Site Recovery Manager 4.0 performance, various dimensions on which the recovery time depends and certain performance tips/considerations on architecting recovery plans to minimize recovery time – few of which are mentioned as follows :
-> Fewer but larger NFS datastores can help speedup a recovery

-> Specifying a non replicated datastore for swap files will eliminate certain remote calls during a recovery and will help improve recovery performance.

-> Even placement of shadow virtual machines across all hosts on the recovery site will ensure maximum parallelism during a recovery.

and so on…
