To be able to use I/O filters in your environment, you must follow specific requirements.
The following requirements apply.
Use the latest version of ESXi and vCenter Server compatible with I/O filters. Older versions might not support I/O filters, or provide only partial support.
Check for any additional requirements that individual partner solutions might have. In specific cases, your environment might need flash devices, extra physical memory, or network connectivity and bandwidth. For information, contact your vendor or your VMware representative.
Web server to host partner packages for filter installation. The server must remain available after initial installation. When a new host joins the cluster, the server pushes appropriate I/O filter components to the host.
