About NetBackup Appliance memory requirements

Beginning with NetBackup Appliance software version 3.1, the security posture of MSDP has been improved by moving from MD5 to SHA-256 for the fingerprinting process. This change has increased the demand on memory consumption in large deduplication pool configurations.

The following describes the guidance for appliance memory footprint requirements that you should follow to ensure optimal performance with MSDP:

  • NetBackup 5230

    For all 3- and 4-storage shelf configurations, Veritas strongly recommends that you upgrade the memory capacity from 128GB to 192GB when configured with an MSDP pool of 144TB or larger.

  • NetBackup 5240

    For all 3- and 4-storage shelf configurations, Veritas strongly recommends that you upgrade the memory capacity from 128GB to a minimum of 192GB when configured with an MSDP pool of 150TB or larger.

    For all 5- and 6-storage shelf configurations, Veritas strongly recommends that you upgrade the memory capacity a minimum of 256GB when configured with an MSDP pool of 250TB or larger.

    A 256GB memory upgrade kit is now available for purchase, which replaces all existing DIMM modules in the appliance. Contact your Veritas account representative for details.

  • NetBackup 5330

    For all storage configurations with an MSDP pool of 458TB or larger, Veritas strongly recommends upgrading the memory capacity to 768GB.

  • NetBackup 5340

    For all storage configurations with an MSDP pool of 960TB or larger, Veritas strongly recommends upgrading the memory capacity to 1536GB.

Other factors can also contribute to additional memory utilization, including but not limited to the following:

  • High concurrent job/stream count

  • Larger MSDP fingerprint cache configurations

  • Master server scheduling responsibilities
