Each Site Recovery Manager instance on Azure VMware Solution can support a certain number of protected virtual machines, protection groups, recovery plans, and concurrent recoveries.
Protection and Recovery Maximums for Site Recovery Manager
|Total number of protected virtual machines per SDDC on Azure VMware Solution||3000
Note: To achieve the 3000 virtual machines scale, you must manually balance the replications between the different vSphere Replication nodes. Contact Microsoft for the scale up/down of vSphere Replication appliances within Azure VMware Solution. You must manually add additional vSphere Replication servers to your on-premises environment, see Deploying Additional vSphere Replication Servers in the vSphere Replication Administration guide.
|Maximum number of protected virtual machines per vSphere Replication appliance (through embedded vSphere Replication server).||300|
|Maximum number of protected virtual machines per vSphere Replication server.||300|
|Total number of virtual machines per protection group||500|
|Total number of recovery plans||250|
|Total number of protection groups per recovery plan||250|
|Total number of virtual machines per recovery plan||2000|
|Total number of virtual machine recoveries that you can start simultaneously across multiple recovery plans||2000|
If you establish a bidirectional protection, in which site B serves as the recovery site for site A and at the same time site A serves as the recovery site for site B, limits apply across both sites, and not per site. In a bidirectional implementation, you can protect a different number of virtual machines on each site, but the total number of protected virtual machines across both sites cannot exceed the limits.
For example, if you protect 1600 virtual machines using vSphere Replication from site A to site B, you can use vSphere Replication to protect a maximum of 1400 virtual machines from site B to site A. If you are using vSphere Replication for a bidirectional protection, you can protect a maximum of 3000 virtual machines across both sites.
IP Customization Maximums for VMware Site Recovery
- 1 IP address
- Subnet information
- 1 gateway server address
- 2 DNS servers (primary and secondary)
You also set 2 WINS addresses for DHCP or IPv4, on Windows virtual machines only.
Recovery Point Objective lower than 15 minutes
For information about Recovery Point Objective (RPO) lower than 15 minutes, see Recovery Point Objective in the vSphere Replication Administration guide.
