Transports enable the exchange of objects and data between
different server processes in your configuration.
About this task
![[Version 8.6 and later]](./icons/v86plus.gif)
Two options exist for transports within
WebSphere® eXtreme Scale: the Object Request Broker
(ORB) or IBM® eXtremeIO (XIO).
- ORB
- When you use the ORB transport, communication between clients
and servers, and between servers within the environment, is handled
by the ORB.

Deprecated: The Object Request Broker (ORB) is deprecated. If you
were not using the ORB in a previous release, use IBM eXtremeIO (XIO)
for your transport mechanism. If you are using the ORB, consider migrating
your configuration to use XIO.
- XIO
- When you use the XIO transport, communication between clients
and servers, and between servers within the environment, is handled
by a transport mechanism that is designed specifically for WebSphere eXtreme Scale. The eXtremeMemory
and eXtreme data format (XDF) features require the XIO transport.
