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

Bidirectional Protection

If you establish 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 1500 virtual machines using vSphere Replication from site A to site B, you can use vSphere Replication to protect a maximum of 500 virtual machines from site B to site A. If you are using vSphere Replication for bidirectional protection, you can protect a maximum of 2000 virtual machines across both sites.

Recovery Maximums for Site Recovery Manager 8.0

Item

Maximum

Total number of concurrently executing recovery plans

10

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

2000

If you protect 5000 virtual machines with Site Recovery Manager, you can recover up to 2000 virtual machines in one recovery plan. After that plan has completed, you can run another recovery plan to recover another 2000 virtual machines. When the second plan has also completed, you can recover the remaining 1000 virtual machines.

If you have 5 recovery plans that each contain 1000 virtual machines, you can start a maximum of two of these plans at the same time. If you have 10 recovery plans that each contains 200 virtual machines, you can start all 10 plans at the same time.

IP Customization Maximums for Site Recovery Manager 8.0

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.
