VMware is adding storage integration features to their flagship vSphere server virtualization product line at a rapid pace. From backup to enterprise array offload, VMware is staking their claim. But information about one new storage feature in vSphere 5 has been scarce: The true nature of the Storage API for Storage Awareness (VASA) is only just beginning to be revealed.
VMwareâ€™s introduced the â€œvStorage APIs for Array Integrationâ€ (VAAI) in vSphere 4.1, and block-heads like me went nuts. Weâ€™ve been trying to integrate storage and servers for decades, and VMwareâ€™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! Letâ€™s take a look at the complete list.
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.
Iomega surprised exactly no one by announcing an updated 12-drive rack mount storage array today. Featuring “Cloud Edition” software introduced earlier this year, the px12-350r also sports mildly updated hardware specs, though still relies on Intel’s “Core2 Duo” CPUs and Gigabit Ethernet. The new device slots in between the desktop px4/px6 line and parent EMC’s new VNXe storage devices.
The next date in my Storage for Virtual Environments seminar series is rapidly approaching, and I hope to see my Ohio readers there! I’ve made major changes to the seminar content recently, updating it with vSphere 5 news and rearranging the whole thing. I still feel like there’s not enough time to get to everything, but it’s a start!
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.
VMware’s vStorage API for Array Integration (VAAI) is one of the most-important storage technology advances of the decade, allowing the ESX to integrate and coordinate operations with supported enterprise storage arrays. IBM was notably absent from the party, but they’ve turned on the VAAI heat, releasing full support for the XIV and SVC and promising DS8000 in the near future.
