I’ve been fortunate to have one of our super sharp product line managers, Alex Jauch (twitter @ajauch), spend some time explaining to me one of the new enabling technologies of vSphere 6.0: VAIO. Let’s take a look at this really powerful capability and see what types of things it can enable and an overview of how it works.
VAIO stands for “vSphere APIs for IO Filtering”
This had for a time colloquially been known as “IO Filters”. Fundamentally, it is a means by which a VM can have its IO safely and securely filtered in accordance with a policy.
VAIO offers partners the ability to put their technology directly into the IO stream of a VM through a filter that intercepts data before it is committed to disk.
Why would I want to do that? What kinds of things can you do with an IO filter?
Well that’s up to our customers and our partners. VAIO is a filtering framework that will initially allow vendors to present capabilities for caching and replication to individual VMs. This will expand over time as partners come on board to write filters for the framework, so you can imagine where this can go for topics such as security, antivirus, encryption and other areas, as the framework matures. VAIO gives us the ability to do stuff to an IO stream in a safe and certified fashion, and manage the whole thing through profiles to ensure we get a view into the IO stream’s compliance with policy!
The VAIO program itself is for partners – the benefit is for consumers who want to do policy based management of their environment and pull in the value of our partner solutions directly into per-VM and indeed per-virtual disk storage management.
When partners create their solutions their data services are surfaced through the Storage Policy Based Management control plane, just like all the rest of our policy-driven storage offerings like Virtual SAN or Virtual Volumes.
Beyond that, because the data services operate at the VM virtual device level, they can also work with just about any type of storage device, again furthering the value of VSAN and VVOLs, and extending the use of these offerings through these additional data services.
How does it work?
The capabilities of a partner filter solution are registered with the VAIO framework, and are surfaced for user interaction in the SPBM Continue reading
