A systems administrator is installing a new Microsoft Windows 2012 host and has granted access to a 2 TB LUN from XtremIO. Quick formatting of the…

VMware vStorage APIs for Array Integration (VAAI) offloads certain storage tasks from the ESXi host

to the storage array.

When VAAI is disabled, operations like quick formatting can take significantly longer because the

tasks are handled by the host instead of being offloaded to the array.

Quick formatting involves writing zeroes to the entire LUN, and without VAAI, this process is much

slower.

Enabling VAAI allows the XtremIO array to handle these operations more efficiently, reducing the

time required for tasks like formatting.
