VMware has released a white paper which discusses stuff you can do to improve performance of the SRM product and its recovery plans.
It includes tips such as:
- Fewer but larger NFS datastores can help speed up 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 much much more!
