Short Description:
John Webster discusses VAAI and HDS implementation for heterogeneous environments
Full Summary:
Hitachi recently announced the availability of support for VMware vStorage APIs for Array Integration (VAAI) on their Virtual Storage Platform (VSP). Previously, VAAI support was offered for VSP systems with Hitachi AMS arrays attached. Now the VSP can extend VAAI capabilities to any third party array supported for connection to the VSP.
We believe that the implementation of VAAI delivers very desirable benefits to medium to large scale VMware environments. VAAI offloads processing for certain operations from ESX hosts to storage systems that support VAAI. This eliminates redundant data flows between servers and storage. It also has the immediate benefit of improving overall ESX host cluster performance by freeing up CPU, memory, and storage bandwidth that would otherwise be consumed in the execution of these processes.
