Each Site Recovery Manager instance on Oracle Cloud 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

Table 1. Protection and Recovery Maximums for Site Recovery Manager
Item Maximum
Total number of protected virtual machines per SDDC on Oracle Cloud VMware Solution 4000
Note: To achieve the 4000 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 environments, 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). 400
Maximum number of protected virtual machines per vSphere Replication server. 400
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

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 2600 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 4000 virtual machines across both sites.

IP Customization Maximums for Site Recovery Manager

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.

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.
