One of the most interesting areas covered at VMworld 2010 was the new storage features in vSphere 4.1. There are two main features I want to cover in depth as I feel they are important indicators of the direction that storage for VMware is heading: Storage I/O Control (SIOC) and vStorage API for Array Integration (VAAI).
Youâ€™ve probably heard VMware virtualization and storage talk about VAAI (vStorage API for Array Integration. If youâ€™ve listened to episode 4 of VIRTUMANIA or watched the recent video from the vExpert Panel session at the Carolina VMUG Summit then youâ€™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?
Coming out of stealth at VMworld 2009 in San Francisco, startup EvoStor exemplifies this new virtualization-optimized storage concept. Taking existing storage concepts like scale-out grid and automated storage layout, EvoStor’s offering is designed exclusively to support the VMware vSphere platform.
