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.

CPU |
Cohesity recommends at least a 2.2-GHz clock rate. A 64-bit processor is required. At least four cores are required. Cohesity recommends eight cores. For 64 TBs of storage, Intel x86-64 architecture requires eight cores. |
Cohesity 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, Cohesity recommends 1GB RAM for 1TB of storage. However if you go beyond 32 TBs of storage, Cohesity 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 NetBackup Software Compatibility List for your NetBackup release on the Cohesity Support website. |

Note:
In some environments, a single host can function as both a NetBackup primary server and as a deduplication server. Such environments typically run fewer than 100 total backup jobs a day. (Total backup jobs are backups to any storage destination, including deduplication and non-deduplication storage.) If you perform more than 100 backups a day, deduplication operations may affect primary server operations.
