# Create SRDF connections

SRDF groups provide a collective data transfer path linking volumes of two separate storage systems.

## About this task

This task provides a mechanism to make a connection to a storage system that is not visible to the Unisphere server and to bring the connected storage system into Unisphere as remote.
