17 General
16 Layer 2 Networking NSX for vSphere offers a layer 2 overlay networking solution as well as layer 2 bridging.
18 Layer 3 Networking NSX provides a multi-tier, in-kernel distributed logical routing system.
19 Firewall NSX for vSphere supports an identity-based firewall in which the firewall rules that protect a given workload can be changed based on the identity of the user whom is using the workload.
20 Load Balancing The NSX for vSphere Edge Service Gateway provides a load balancing service to distribute load across multiple workloads.
21 VPN The NSX for vSphere Edge Service Gateway provides a SSL VPN service.

Operational Limits Protection limits Maximum number of protected virtual machines per vSphere Replication appliance (via embedded vSphere Replication server) 200
Operational Limits Protection limits Maximum number of protected virtual machines per vSphere Replication server 200 The maximum number of virtual machines that you can assign to each vSphere Replication server is 200. So, if you deploy the maximum of 9 additional vSphere Replication servers, the total number of virtual machines that you can protect is 2000 between different vCenter Server instances and a maximum of 500 replications in a single vCenter Server instance.
Operational Limits Protection limits Maximum number of virtual machines managed per vSphere Replication appliance in a single vCenter server instance 500
Operational Limits Protection limits Maximum number of virtual machines configured for replication at a time 20

Operational Limits Deployment Limits vSphere Replication appliances per vCenter Server instance 1 You can only deploy one vSphere Replication appliance on a vCenter Server instance. When you deploy another vSphere Replication appliance, during the boot process vSphere Replication detects another appliance already deployed and registered as an extension to vCenter Server. You have to confirm if you want to proceed with the new appliance and recreate all replications or shut it down and reboot the old appliance to restore the o…
