I suspect 2680 should work but until now we had no opportunity to test it carefully.
Until now, Hard Disk Sentinel was successfully tested with 2220, 2320, 2640 from RocketRAID 2xxx series, and disk information are available in both RAID and non-RAID mode for both SATA/SAS disks.
A RocketRAID 2640x4 and an LSI SAS 3000 card is used now in this system as they both provide all disk information to Hard Disk Sentinel correctly.
We already contacted Adaptec many times because we really want to add support for their controllers. However, without the programming reference of their cards it is not really possible (so it is not our lazyness
). They never respond so it seems they do not want software support for their controllers. It's a shame. The same is true for some other manufacturers (eg. Promise) that's why their controllers do not or only partially supported.
