This Veeam Ready test was performed with storage having a configuration that includes SSD/Flash.  As such, this classification only applies to similar configurations in which the same amount or more SSD drives are used.  The use of non-SSD drives may negatively impact performance.
SMB write-through is supported on this platform and was used in the Veeam Ready testing. Continuous availability must be enabled for SMB share at the time of creation as it cannot be configured retrospectively. For more details about continuous availability read more at KB3124

Veeam testing configuration

Veeam Build Number: 12.0.0.1420 P20230223

Vendor recommended configuration

Vendor Settings:

  • Does vendor solution support SMB write-through? Yes, SMB3 Continuous Availability was enabled which uses write-through.  To enable, create a new SMB share with the option “Enable continuous availability on the share” selected.  This setting cannot be disabled and cannot be enabled on existing shares, only new shares.
  • Was SMB write-through enabled during the testing? Yes
  • Caching used: SSD
  • Read/write caching: The OneFS L1, L2, and L3 cache are described in the following article

Additional Considerations:

  • Dell PowerScale has a default maximum file size of 4TiB, optionally 16TiB on supported cluster configurations. Active Full + Incremental processing is advised.
  • Veeam Scale Out Backup Repository can distribute the load across the PowerScale cluster via multiple Backup Repository Extents each defined to use a different cluster node DNS A record and path. When backups exceed the maximum file size (as noted above), even with Veeam deduplication and compression, other considerations should be made such as the below software.
  • The dsmISI software automates load balancing, mitigate file size limitations, and supports block cloning for fast synthetic processing and to save space (Read More).
