Specifying NAS Volumes Using the DMA

To perform backup and restore operations, the DMA server must be configured to be able to access the FluidFS cluster.

On each DMA server, you must configure the following components:

• Client VIP (or a DNS name) that the DMA server accesses. If you change the client VIP, you must also make the appropriate change on the DMA servers.
  NOTE:NDMP has no load balancing built in. A single DMA backing up 10 NAS volumes from a single client VIP forces all 10 sessions on the same NAS controller. Therefore, use DNS round-robin to provide load balancing by specifying the DNS name of the FluidFS cluster in the DMA.
• NDMP user name and password (default user name is backup_user)
• Port that the NDMP server monitors for incoming connections (default port is 10000)

(Optional) In addition, some DMA servers require more information, such as the host name of the FluidFS cluster, OS type, product name , and vendor name.

• Host name of the FluidFS cluster, which uses the following format:controller_number.FluidFS_cluster_name
• OS type – DellFluid File System
• Product – Compellent FS8600
• Vendor – Dell

Most backup applications automatically list the available NAS volumes to back up. Otherwise, you can manually type in the NAS volume path. The FluidFS cluster exposes backup NAS volumes at the following path:

/NAS_volume_name

To improve data transfer speed, increase the number of concurrent backup jobs to more than one per NAS controller, distributing the load across the available NAS controllers.
