Determining the Configuration for the Shared SAN Data Server

Use the following sections to first decide how you are going to provision the storage to the data server. Then decide how you are going to share the mount paths created on the provisioned storage with the MediaAgents.

The following three modes of storage are supported:

  • Direct attached storage mode

    In the direct attached storage mode the MediaAgents can access the mount points that are created on the disks that are directly attached to the SAN data server through SCSI transport types. For example: SAS and SATA.

  • SAN attached storage mode

    In the SAN attached storage mode the mount points that are created on the disk array which are connected through fibre channel or iSCSI are accessed by the MediaAgents.

  • The mixed mode

    In the mixed mode is a combination of the direct and SAN attached storage mode.

The MediaAgents are configured to access the SAN data server through either iSCSI or the fibre channel.

You can use the following table to determine the required configuration in your particular setup to configure the shared SAN data server.
