Deploy and Configure I/O Filters in the vSphere Environment
You can install the I/O filters in your vSphere environment and then enable data services that the filters provide on your virtual machines.
VMware partners create I/O filters through the vSphere APIs for I/O Filtering (VAIO) developer program and distribute them as filter packages. Packages offered as vSphere Installation Bundles (VIBs) can include I/O filter daemons, CIM providers, and other associated components. For information, contact your vendor or your VMware representative.
