Qtier not available in QuTS hero

Last modified date: 2022-06-24

Applied models:

Hero NAS Series

Applied Firmware:

ALL

If you are trying to enable Qtier in QuTS hero and realize that there is no button to do it, this is because QTS-Hero does not support Qtier. Qtier is based on storage stack, which was implemented in dm-thin pool and In ZFS (QuTS hero file system) unfortunately there is not. For this reason Qtier can not be enabled.

As an alternative you can use SSD Cache acceleration, for sure is not complete the same as Qtier but could help to improve performances if the number of HDDs in the RAID to accelerate is not more than 10.
