About MSDP server requirements
The host computer's CPU and memory constrain how many jobs can run concurrently. The storage server requires enough capability for deduplication and for storage management unless you offload some of the deduplication to load balancing servers.
Table: MSDP server minimum requirements shows the minimum requirements for MSDP servers. NetBackup deduplication servers are always NetBackup media servers.
Processors for deduplication should have a high clock rate and high floating point performance. Furthermore, high throughput per core is desirable. Each backup stream uses a separate core.
Intel and AMD have similar performance and perform well on single core throughput.
Newer SPARC processors, such as the SPARC64 VII, provide the single core throughput that is similar to AMD and Intel. Alternatively, UltraSPARC T1 and T2 single core performance does not approach that of the AMD and Intel processors. Tests show that the UltraSPARC processors can achieve high aggregate throughput. However, they require eight times as many backup streams as AMD and Intel processors to do so.

| Component | Storage server | Load balancing server |

CPU |
Veritas recommends at least a 2.2-GHz clock rate. A 64-bit processor is required. At least four cores are required. Veritas recommends eight cores. For 64 TBs of storage, Intel x86-64 architecture requires eight cores. |
Veritas recommends at least a 2.2-GHz clock rate. A 64-bit processor is required. At least two cores are required. Depending on throughput requirements, more cores may be helpful. |
|
RAM |
From 8 TBs to 32 TBs of storage, Veritas recommends 1GB RAM for 1TB of storage. However, beyond 32 TBs storage, Veritas recommends more than 32GBs of RAM for better and enhanced performance. |
4 GBs. |
|
Operating system |
The operating system must be a supported 64-bit operating system. See the operating system compatibility list for your NetBackup release on the Veritas Support website. |
The operating system must be a supported 64-bit operating system. Load balancing for Cloud Catalyst storage servers or Cloud Catalyst appliances is supported. See the following topic for configuration considerations. See Configuring source control or target control optimized duplication for Cloud Catalyst. See the operating system compatibility list for your NetBackup release on the following website. |
A Veritas tech note provides detailed information about and examples for sizing the hosts for deduplication. Information includes the number of the NICs or the HBAs for each server to support your performance objectives.

This page has been updated for NetBackup version 7.5.
Note:
In some environments, a single host can function as both a NetBackup master server and as a deduplication server. Such environments typically run fewer than 100 total backup jobs a day. (Total backup jobs means backups to any storage destination, including deduplication and non-deduplication storage.) If you perform more than 100 backups a day, deduplication operations may affect master server operations.
