Each
instance can support a certain number of protected virtual machines, protection groups, recovery plans, and concurrent recoveries. You must use a VPN connection or Direct Connect to access the

During the initial activation of
, the service is deployed with one
appliance. When you reach 400 incoming replications for the
SDDC, a second
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
servers to your on-premises environment, see Deploying Additional Servers. To achieve the 4000 virtual machines scale, you must have vSphere 8.0,
vSphere Replication
8.6 and later, and
VMware Cloud on Dell EMC
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
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
for a bidirectional protection, you can protect a maximum of 4000 virtual machines across both sites.

IP Customization Maximums for

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
