Currently i have VMware infra. are three hosts operated by ESXi 5.1 linked single SAN storage.
Have any application can help to replicate those 20 opearing virtual machine to other ESXi hosts with real time.
I tried to operate this real time backup by Veeam 5.5 continuousy . But it will seriously affected original hosts and virual mahcine performance.
This process purpose to keep those virtual machines with real time copy on other host to avoid single storage failure risk. But' I don't have budget to purchase 2nd SAN storagre.
