Technical Paper: StarWind Virtual SAN VAAI (vStorage API for Array Integration) Configuration and Performance Tuning Guide

VAAI (vStorage API for Array Integration) is a complex of technologies designed to offload certain VM disk operations to the storage array. With VAAI is enabled during working with the disk subsystem, the ESXi host sends the commands to the array to perform the specific operations. Therefore, there is no need to process all the data. This guide describes how to configure and check VAAI functioning in StarWind Virtual SAN.

Webinar: Make your storage work for you: VAAI and ODX offload up to 30% of disk operations to the SAN

Published: April 15, 2015

Hypervisor CPU and Networking overhead is a common issue for operations like VM provisioning, migration, and cloning. There should be a way to enhance performance by offloading the unnecessary CPU load and shrinking the SAN traffic. ODX and VAAI features do exactly this by offloading routine disk tasks to the storage array so they will be executed more effectively.
