Each VMware Site Recovery instance can support a certain number of protected virtual machines, protection groups, recovery plans, and concurrent recoveries.

Protection and Recovery Maximums for VMware Site Recovery

Table 1. Protection and Recovery Maximums for VMware Site Recovery

Item

Maximum

Total number of protected virtual machines per NSX-T based SDDC on VMware Cloud™ on AWS

1000

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. To achieve the 1000 virtual machines scale, you must manually balance the replications between the two vSphere Replication nodes.

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

1000

Total number of virtual machine recoveries that you can start simultaneously across multiple recovery plans

1000

Bidirectional Protection

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 750 virtual machines using vSphere Replication from site A to site B, you can use vSphere Replication to protect a maximum of 250 virtual machines from site B to site A. If you are using vSphere Replication for a bidirectional protection, you can protect a maximum of 1000 virtual machines across both sites.

IP Customization Maximums for VMware Site Recovery

If you implement IP customization for recovered virtual machines, you can configure a maximum of one IP address for each NIC, using DHCP, static IPv4, or static IPv6. For static IPv4 or IPv6 addresses, you provide the following information per NIC:

  • 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.
