General
Deployment type
Zerto Virtual Manager (VM) is required at each site, Zerto Virtual Replication Appliance (VRA) is required on each ESXi host. A VIB can be used for ESXi 5.5 or newer.
With vSphere Replication, a minimum of one/maximum of 10 vSphere Replication appliances are deployed at each site regardless of the number of hosts. The amount of vSphere Replication appliances depends on the number of VMs to be replicated (200 VMs per replication appliance).
ASR is consumed as a service, but requires some on-premises components.
Replication options
