Known Issues

(Updated June 29 2021)

If you encounter problems running the benchmark, please review the following documents for known issues. If your issue is not addressed, current SPECstorage Solution 2020 software licensees may direct support questions to the technical support mailing list at; please be prepared to provide your license number upon request.

  • June 29, 2021: A performance neutral patch which fixes a code path where the vendor has modified the storage2020.yaml file and enabled "skip_init= 1". (This is not permitted for publication but is used by vendors for internal testing because it saves time in nightly regression tests.) The use of skip_init had an unintended side effect on workloads that contained attributes that enabled O_DIRECT on file I/O calls. The patch eliminates the side effect where use of skip_init in combination with the use of O_DIRECT caused the transfer sizes to not match the definitions of the workloads.
  • April 12, 2021: A performance-neutral patch is available to fix an unexpected benchmark termination at a certain load increment.
