Each VMware Site Recovery instance can support a certain number of protected virtual machines, protection groups, recovery plans, and concurrent recoveries. You must use a VPN connection to access the VMware Site Recovery HTML 5 client.
Protection and Recovery Maximums for VMware Site Recovery
|Total number of protected virtual machines per NSX-T based SDDC on VMware Cloud™ on AWS||1500
Note: During the initial activation of VMware Site Recovery, the service is deployed with one vSphere Replication appliance. When you reach 350 incoming replications for the VMware Cloud™ on AWS SDDC, a second vSphere Replication appliance is provisioned automatically. A third vSphere Replication appliance is provisioned when you reach 700 incoming replications, a fourth appliance is provisioned when you reach 1050 incoming replications, and a fifth when you reach over 1400 replications. To achieve the 1500 virtual machines scale, you must manually balance the replications between the different vSphere Replication nodes. You must manually add additional vSphere Replication servers to your on-premises environment, see Deploying Additional vSphere Replication Servers.
|Total number of virtual machines per NSX Data Center for vSphere based SDDC on VMware Cloud™ on AWS||500
Note: NSX Data Center for vSphere (NSX-V) has reached end of life as of August 30, 2019 and will no longer be supported.
|Maximum number of protected virtual machines per vSphere Replication appliance (via embedded vSphere Replication server.)||200|
|Maximum number of protected virtual machines per vSphere Replication server.||200|
|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||1500|
|Total number of virtual machine recoveries that you can start simultaneously across multiple recovery plans||1500|
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 850 virtual machines using vSphere Replication from site A to site B, you can use vSphere Replication to protect a maximum of 650 virtual machines from site B to site A. If you are using vSphere Replication for a bidirectional protection, you can protect a maximum of 1500 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 How the 5 Minute Recovery Point Objective Works in the vSphere Replication Administration guide.
