3PAR VAAI Plug-in 1.1.0 for VMware vSphere 4.1 Users Guide are typically implemented in-band from ESX to a disk array. ESX extensions to make use of these primitives are collectively referred to as vStorage APIs for Array Integration (VAAI). 2.2 About 3PAR VAAI Plug-in 1.1.0 for VMware vSphere 4.1 To keep up with new advances in cloud computing, enhanced capabilities are required by the SCSI layer stack so that SCSI can meet the demands of emerging virtualized infrastructures.
3PAR VAAI Plug-in 1.1.0 for VMware vSphere 4.1 Users Guide 2.2.1 Hardware Assisted Locking (ATS) Rather than locking the entire LUN, Hardware Assisted Locking (ATS) only locks the blocks on the LUN that are allocated to the VMDK. This enhanced capability is intended to help virtualized data centers in at least two important ways.
3PAR VAAI Plug-in 1.1.0 for VMware vSphere 4.1 Users Guide Block Zeroing Increases performance and efficiency by eliminating the writing of zeros as data by the host for the purpose of "cleaning" space for a VMDK. Using the WRITE-SAME command, VMware now transfers the overhead associated with these writes to the storage array by instructing the storage array to assume the burden of writing the zeros on these newly allocated blocks.
