Storage Arrays Critical to vSphere 4.1 EnhancementsJuly 15, 2010
VMware's Tuesday release of vSphere 4.1 features a slew of new storage features that bring storage hardware acceleration to the company's virtualization platform. Enterprise Storage Forum reports.
The bulk of the storage upgrades in vSphere 4.1 have been made possible through the new VMware vStorage APIs for Array Integration (VAAI). Specifically, new hardware acceleration that allows VMware ESX servers to offload specific storage operations to compliant storage hardware.
With an assist from storage arrays, ESX servers can perform storage operations faster and consumes less CPU, memory, and storage fabric bandwidth.
There are three major new storage integration points in vSphere 4.1 that put the heavy lifting in the hands of the array: Block Zero, Full Copy and Hardware Assisted Locking.
