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
| Item | Maximum |
|---|---|
| Total number of protected virtual machines per NSX-T based SDDC on VMware Cloud™ on AWS | 4000
Note: During the initial activation of
VMware Site Recovery, the service is deployed with one
vSphere Replication appliance. When you reach 400 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 800 incoming replications, a fourth appliance is provisioned when you reach 1200 incoming replications, a fifth appliance is provisioned when you reach over 1600 replications, and so on. 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 on-premises environment, see
Deploying Additional vSphere Replication Servers. To achieve the 4000 virtual machines scale, you must have vSphere 8.0,
vSphere Replication 8.6 and later, and
VMware Cloud on AWS SDDC version 1.20 and later.
vSphere Replication 8.4 and later uses only embedded database and requires additional configuration to enable the support of a maximum of 4000 replications. See
https://kb.vmware.com/s/article/2102463.

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 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.
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.
Protection and Recovery Maximums for VMware Site Recovery with enhanced replication
Important: Enhanced replication capability is supported only where the target of replication is a site on a
VMware Cloud on AWS SDDC version 1.22 with
Site Recovery Manager 8.7 or later and
vSphere Replication 8.7 or later. Enhanced replication capability requires
vCenter Server 8.0u2, and
ESXi host 8.0u2 on the target site when the target is an on-premises SDDC..
| Item | Maximum |
|---|---|
| Total number of protected virtual machines per NSX-T based SDDC on VMware Cloud™ on AWS | 4000
Note:
VMware Site Recovery with enhanced replication capability including 1 minute RPO, auto-scaling, and load balancing, scales to a limit of 4000 protected VMs by provisioning additional
ESXi hosts to accommodate the workload requirements. Enhanced replication distributes the replications on all hosts available in the target cluster. Re-balancing of the workload occurs automatically every 30 minutes. The number of replicated VMs per host on the target site depends on, but is not limited to the virtual machines disks size, number of disks, change rate, and RPO.
|
| Total number of protected virtual machines per NSX-T based SDDC on VMware Cloud™ on AWS with vSphere Replication 9.0.1 and later | 5000
Note:
VMware Site Recovery with enhanced replication capability including 1 minute RPO, auto-scaling, and load balancing, scales to a limit of 5000 protected VMs by provisioning additional
ESXi hosts to accommodate the workload requirements. Enhanced replication distributes the replications on all hosts available in the target cluster. Re-balancing of the workload occurs automatically every 30 minutes. The number of replicated VMs per host on the target site depends on, but is not limited to the virtual machines disks size, number of disks, change rate, and RPO.

| Total number of virtual machines per protection group | 1500 |
| Total number of recovery plans | 250 |
| Total number of protection groups per recovery plan | 250 |
| Maximum number of protected disks per virtual machine on ESXi 8.0 or earlier version. | 64 |
| Maximum number of protected disks per virtual machine on ESXi 8.0 Update 1 or later version. | 256 |

Protection and Recovery Maximums for VMware Site Recovery on VMware Cloud™ on AWS Outposts
With
VMware Site Recovery on
VMware Cloud™ on AWS Outposts you can plan, test, and run the recovery of virtual machines between a protected
vCenter Server on-premises site and a recovery
vCenter Server site on
VMware Cloud on AWS Outposts and the reverse, between a protected
vCenter Server site on
VMware Cloud on AWS Outpost SDDC and a recovery
vCenter Server site on
VMware Cloud on AWS SDDC and the reverse, and between
vCenter Server sites on two
VMware Cloud on AWS Outposts SDDCs.
| Item | Maximum |
