VMware’s introduced the “vStorage APIs for Array Integration†(VAAI) in vSphere 4.1, and block-heads like me went nuts. We’ve been trying to integrate storage and servers for decades, and VMware’s APIs finally allowed this to work in truly seamless fashion. But the world of VAAI is a thicket of bizarre naming and puzzling functionality. Some VAAI primitives are ignored or even hidden! Let’s take a look at the complete list.

VMware as Oedipus: How Server Virtualization will Change Storage Forever
VMware doesn’t want to hurt its parent, EMC, any more than Oedipus desired his own parents’ fate. Indeed, VMware spends an incredible amount of time and effort innovating both internal and external integration features for storage. They do this to meet their own I/O demands, not out of bloodlust or hubris. But like the tragic hero in a Greek play, VMware is destined to anonymize and homogenized enterprise storage, and this will drastically affect the future of EMC and other pure storage vendors.
FalconStor Brings VAAI Support To Every Storage Array
I do not necessarily endorse or recommend FalconStor NSS over competing products from more familiar names, but I commend them for adding VAAI support. There the first small vendor to do so, and their software virtualization platform spreads the availability of this important software capability.
Storage Changes in VMware vSphere 5
Once again, VMware added a ton of new storage enhancements to vSphere. With storage rapidly becoming the limiting factor in scalability and performance of virtual machine environments, this is no surprise. Also not surprising is the fact that major features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses.
I’m a Microsoft MVP and VMware vExpert for 2011!
I sincerely appreciate receiving these awards, and thank Microsoft and VMware for their faith in me. I also sincerely appreciate the contribution and feedback I get from the technical community around me, and thank you just as much for these awards. I would not have received them without the readers of my blog, the attendees at my seminars, and the vast community that I interact with on a daily basis. Thank you!
