Troubleshooting VAIO Filters

vSphere APIs for I/O Filtering (VAIO) provide a framework that allows third parties to create software components called I/O filters. The filters can be installed on ESXi hosts and can offer additional data services to virtual machines by processing I/O requests that move between the guest operating system of a virtual machine and virtual disks.

For information about I/O filters, see the see the vSphere Storagepublication.
