Supported external storage communication methods

Determine which interface to your storage system works best in your network

Selection of a communication method depends on which storage area network (SAN) you are planning to use, supporting hardware and software, and network size/topology.

There are several ways that PowerHA can work with the storage devices. These include:

Data Storage command-line interface (DSCLI)
Storage Area Network (SAN) volume controller
Copy Services Management (CSM)
