While we were looking deeper at this settings, we read again the great post of Cormac explaining this feature, and more precisely the new behavior since 5. U2 Heads Up ATS Miscompare detected between test and set HB images. There is now an official VMware KB KB2. ATS heartbeat before and after 5. U2 A change in the VMFS heartbeat update method was introduced in VMware v. Sphere ESXi 5. 5, Update 2 to help optimize the VMFS heartbeat process. Whereas the legacy method involves plain SCSI reads and writes with the VMware ESXi kernel handling validation, the new method offloads the validation step to the storage system. This is similar to other VAAI related offloads. This optimization results in a significant increase in the volume of ATS commands the ESXi kernel issues to the storage system, and resulting increased load on the storage system. Under certain circumstances VMFS heartbeat using ATS may fail with false ATS miscompare which causes the ESXi kernel to reverify its access to VMFS datastores. This leads to the Lost access to datastore messages. The Support Case we opened at Solid. Fire support confirm this behavior, here is an excerpt of their answer SF is a 4. K block size array internally but ESX only works with 5. ESX issues single 5. ATS commands, which requires the SF array to perform an internal read modify write for every ATS command. If ESX could issue a 4. K ATS command eight 5. Free Capture Software 60 Fps there. ATS performance should be better. Essentially, every ATS operation is an unaligned IO. The Solid. Fire support ask us to to disable ATS heartbeat in order to switch back to legacy SCSI 2 reservations only for the heartbeat of course. As described on the VMware KB, you can do this thanks to Power.
