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 http://www.vmware.com/files/pdf/VMware-vCenter-SRM-WP-EN.pdf

You can also find it under the technical resources section at http://www.vmware.com/products/site-recovery-manager/resource.html.

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...

You will also find Database sizing guides under the Tools section which will help you in estimating the Site Recovery Manager Database growth as a function of the number of protection groups, recovery plans and more .
