Rick Crisci explains how atomic test and set (ATS) uses the vSphere API for Array Integration (VAAI) to reduce the impact of SCSI reservations.
- [Instructor] In this video, I'll explain VAAI primitives…and how they can be used to make certain storage tasks…more efficient.…VAAI primitives define storage tasks…that can be offloaded to a storage array.…There's many different operations…that can actually be offloaded to a storage array…from an ESXi host.…When these operations are offloaded to the storage array,…they become much more efficient…and they happen much more quickly.…Now, some of these operations include zeroing disks,…cloning virtual machines,…and migrating data from one datastore to another.…
If a VAAI storage array is not used for these tasks,…the data mover of the ESXi host…must perform these operations.…And most of the time what that means is…data is unnecessarily copied…from the storage array to the ESXi host…and then right back down to another datastore…out of the same storage array.…So in this video, we're going to cover…a few key VAAI primitives.…The first primitive that we'll talk about…is Atomic Test and Set.…
We'll then cover XCOPY,…Write Same,…
