Veeam Testing Configuration

Veeam Build Number: 12.0.0.1420 P20230718

Vendor recommended configuration

Vendor Settings:

  • Caching used: Yes
  • Read/write caching: Secondary ARC device acts as a read cache. ZFS uses ARC to cache recently and frequently accessed data. As new data is added to primary ARC the older data is moved to secondary ARC, which can be accessed faster than data off of the HDD array. In this test the 960GB SAS SSD was used as secondary ARC. ZFS SLOG is used for synchronous writes. Data is first written to RAM, then to the SLOG device, and then moved to the HDD array. For synchronous writes this allows the file system to confirm that data is written to non-volatile storage far faster than HDD allows. This test used the 3.84TB SAS SSD as SLOG, overprovisioned to 16GB.
  • Networking: MTU=9000
  • Multipathing / link aggregation used: No
  • Array deduplication used in testing: No
  • Array compression used in testing: Yes
