About MSDP storage and connectivity requirements
The following subsections describe the storage and the connectivity requirements for the NetBackup Media Server Deduplication Option.
The following are the minimum requirements for single stream read or write performance for each disk volume. Greater individual data stream capability or aggregate capability may be required to satisfy your objectives for writing to and reading from disk.
Up to 32 TBs of storage
200 MB/sec for enterprise-level performance.
32 to 48 TBs of storage
Veritas recommends that you store the data and the deduplication database on separate disk volumes, each with 200 MB/sec read or write speed. Neither should be stored on the system disk.
48 to 64 TBs of storage
Veritas recommends that you store the data and the deduplication database on separate disk volumes, each with 250 MB/sec read or write speed. Neither should be stored on the system disk.
96 TBs of storage
96 TBs of storage require four separate volumes, each with 250 MB/sec read or write speed. You cannot use the system disk of the storage server host for any of the required volumes.
250 TBs of storage
Local disk storage may leave you vulnerable in a disaster. SAN disk can be remounted at a newly provisioned server with the same name.
NetBackup requires the exclusive use of the disk resources. If the storage is also used for purposes other than backups, NetBackup cannot manage disk pool capacity or manage storage lifecycle policies correctly. Therefore, NetBackup must be the only entity that uses the storage.
NetBackupdoes not support the following storage types for deduplication storage:
The NetBackup compatibility lists are the definitive source for supported operating systems, computers, and peripherals. See the compatibility lists available at the following website:
The storage must be provisioned and operational before you can configure deduplication in NetBackup.
See About provisioning the storage for MSDP.
The storage must be direct-attached storage (DAS), internal disks, or connected by a dedicated, low latency storage area network (Fibre Channel or iSCSI).
A storage area network should conform to the following criteria:
Maximum 0.1-millisecond latency per round trip.
Enough bandwidth on the storage network to satisfy your throughput objectives.
Veritas supports iSCSI on storage networks with at least 10-Gigabit Ethernet network bandwidth.
Veritas recommends the Fibre Channel storage networks with at least 4-Gigabit network bandwidth.
The storage server should have an HBA or HBAs dedicated to the storage. Those HBAs must have enough bandwidth to satisfy your throughput objectives.
