So operations like Storage vMotion, Cloning or Deploy from Template. Telling an array to move something from location A to location B is much faster than having ESXi issue tons of reads and writes over the SAN and it also therefore reduces CPU overhead on the ESXi host and reduces traffic on the SAN. Faster cloning/migration and less overhead–yay! This lets ESXi focus on what it does best: manage and run virtual machines while letting the array do what it does best: manage and move around data.
