You’ve probably heard VMware virtualization and storage talk about VAAI (vStorage API for Array Integration. If you’ve listened to episode 4 of VIRTUMANIA or watched the recent video from the vExpert Panel session at the Carolina VMUG Summit then you’ve heard me talk about it with some of those most in the know on the topic. But what is VAAI exactly and how will it impact virtualization in the future?

Side note – I hate saying “V A A I”. IMO it’s quite a tongue twister. I have adopted saying “V double A I” because it is much easier to get out.

VAAI Introduced 2 years ago

Although it does not exist in vSphere 4.0 today, believe it or not VAAI was first introduced at VMworld 2008 when the vStorage API was announced.

VMware Unveils New vStorage Technologies to Deliver Leading Efficiency and Manageability for the Virtual Datacenter Operating System

New Capabilities Deliver Deeper Integration with Storage Partner Functionality
vStorage enables intelligent integration of storage products within the Virtual Datacenter OS through the new vStorage APIs. 

vStorage APIs deliver tight integration of advanced capabilities from storage partners with the Virtual Datacenter OS from VMware.  vStorage APIs for array integration will enable customers to leverage array-based capabilities, such as snapshots, provisioning, replication and restore, directly with individual virtual machines in conjunction with the clustering and pooling capabilities of VMware Infrastructure.  vStorage APIs for multi-pathing will provide customers the ability to integrate advanced load balancing capabilities provided by leading partners’ multi-pathing software with their virtual environment.

If you are like me you were probably so overwhelmed by the news of the VCD-OS (That’s what VMware was calling the hybrid Cloud at the time … I guess?) that you missed (or were not capable or ready to comprehend) how complete of a strategy already existed for building Infrastructure as a service (IaaS) with the vStorage API. For me, looking back 2 years later it is amazing to me it was all there – at least in concept.

Don’t confuse VADP and VAAI

VAAI is only one part of the vStorage API. VADP (vStorage API for Data Protection) is another, but the these two seem to have been easily confused lately. VADP is
