CIM Provider If VMware partners develop the I/O filters, the partners can provide an
optional component that configures and manages I/O filter plug-ins.
vSphere Web Client
Plug-In
When developing I/O filters, VMware partners can include this optional
plug-in. The plug-in provides vSphere administrators with methods for
communication with an I/O filter CIM provider to receive monitoring
information about the I/O filter status. It can also send configuration
commands to the CIM provider to configure its I/O filters.
I/O Filter Daemon An optional component that VMware partners can develop. You can use it
as an extra service that interacts with the individual filter instances running
on a host. The service can establish network communication channels
across the hosts.
The following figure illustrates the components of I/O filtering and the flow of I/O between the guest OS
