The operation of vSphere Replication depends on certain services, ports, and external interfaces.

vSphere Replication Services

The operation of vSphere Replication depends on several services that run on the vSphere Replication virtual appliance.

Table 1. vSphere Replication Services

Service Name

Startup Type

Description

hms

Automatic for the vSphere Replication appliance. Disabled for the vSphere Replication add-on appliance.

vSphere Replication Management Service

hbrsrv

Automatic

vSphere Replication Service

sshd

Automatic

Disabled by default.

ntp

Automatic

Time service for syncing-up with Internet Time Server through Network Time Protocol.

Note:

After you install or upgrade a vSphere Replication virtual appliance, you must synchronize the appliance with a time server.

vaos

Automatic

Guest OS initialization that drives network settings, host name settings, ssh keys creation, EULA acceptance, boot scripts execution, and VAMI initialization.

Communication Ports

vSphere Replication uses several communication ports and protocols.

The vSphere Replication appliance requires certain ports to be open.

Note:

vSphere Replication servers must have NFC traffic access to target ESXi hosts.

Remote vCenter Server

80

TCP

All management traffic to the vSphere Replication appliance goes to port 80 on the vCenter Server proxy system.

vSphere Replication server in the vSphere Replication appliance

Remote ESXi host

80

HTTP

Used to establish the connection before initial replication starts.

vSphere Replication server in the vSphere Replication appliance

Remote ESXi host

902

TCP and UDP

Used by vSphere Replication servers to send replication traffic to the destination ESXi hosts.

Intra-site management traffic from the vSphere Replication Management server to additional vSphere Replication server in the environment.

vSphere Web Client on the source site

vCenter Server Inventory Service on the target site

10443

HTTPS

ThevSphere Replication UI uses the Inventory Service of the remote vCenter Server to list target datastores.

ESXi host on source site

vSphere Replication server at the target site

31031

Initial and outgoing replication traffic from the ESXi host at the source site to the vSphere Replication appliance or vSphere Replication server at the target site.

If you deploy additional vSphere ReplicationvSphere Replication servers, you must open the ports that vSphere Replication requires on those servers.

Intra-site management traffic from the vSphere Replication appliance or vSphere Replication Management server to the vSphere Replication servers.

ESXi host at the source site

vSphere Replication server

31031

Initial and outgoing replication traffic from the ESXi host at the source site to the vSphere Replication appliance or vSphere Replication server at the target site.

When you create a connection to the cloud, the vCloud Tunneling Agent in the vSphere Replication appliance creates a tunnel to secure the transfer of replication data to your cloud organization.

Port

Protocol

Description

The ESXi host at the source site

The vCenter Server at the source site

vSphere Replication appliance connects to this port to send replication data to a cloud organization.

The ESXi host at the source site

The vSphere Replication appliance at the source site

10000-10010

TCP

The vCloud Tunneling Agent opens one of these ports on the vSphere Replication appliance. ESXi hosts connect to that port to send replication data to a cloud organization.

Open Source and Third-Party Components

For the complete text of the open source licenses, a list of all open source and third-party components, and the open source code used in vSphere Replication, you can go to http://www.vmware.com/download/open_source.html and see the VMware vSphere Replication Open Source and Licenses section under the VMware vSphere Open Source link. If certain open source license requires it, the vSphere Replication Open Source Disclosure Package (ODP) contains text files with instructions how to build and replace the software libraries.
