A VMware framework that lets CDP for vSphere intercept each write as it happens, through a Veeam filter on every ESXi host, so no snapshots have to be taken.
Also called VAIO.

Each book explains vSphere APIs for I/O Filtering in context, with comparison tables and the common traps.
Terms in this definition
- CDP
Cisco Discovery Protocol lets an administrator see which port on a physical switch each host uplink is cabled to. vSphere supports it on distributed and standard switches alike, while LLDP requires a distributed switch.
- vSphere
VMware's platform for virtualisation, made up of vCenter and ESX hosts, supplying compute for VCF clusters.
- FILTER
Returns just those rows of a table that meet a condition. In CALCULATE it handles conditions too complex for a Boolean filter argument, though a Boolean filter is faster whenever one will work.
- ESX
VMware's bare-metal hypervisor, installed on each host in a VCF fleet. Up to version 9.0 it was known as ESXi.
Related terms
- Continuous Data Protection
Replicates vSphere VMs by capturing every write through VAIO, with no snapshots, so the RPO is nearly zero and replicas can start at once. (Unrelated to Cisco Discovery Protocol.)
- Universal CDP
Continuous data protection not restricted to vSphere: physical, cloud and virtual machines alike can be replicated, with VMware vSphere hosts or clusters as the destination. Each source runs Veeam's CDP Agent Service and CDP Volume Filter Driver in place of a VAIO filter.
