How The 7.5 Concurrent VM Power On Feature Can Lower RTO On Failover

Viewed 409 times


Administrators may have larger VPGs (20+ VMs) where the RTO is higher than expected and it is determined from Recovery Reports/log analysis that the Recovery VMs are not powered on concurrently, rather in serial.


By upgrading to Zerto 7.5 code family, Zerto now handles concurrent power on of Recovery VMs that are created by a Failover/Move operation.

By default, the ZVM will request VCenter turn on a batch of 20 VMs at once, in parallel. Once this job is accepted, the next 20 VM batch will be sent for power on as well.

If there is a need to have a batch be larger than 20 VMs, kindly contact Zerto Support for assistance.
