SQL 2005 virtual device interface network adapters

In one of the performance tuning articles virtual device interface network adapters are mentioned as follows: SQL Server 2000 Enterprise Edition offers support for virtual device interface (VDI) network card adapters, which can greatly speed the network performance of SQL Server. This new style of network card adapter provides a much more efficient protocol stack, which not only boosts network throughput, it also reduces the workload on the server, further increasing your server’s performance. I can not find any information on how this technology works, or is configured. Can you point me to more documentation or supply descriptions? I am using SQL Server 2005 Enterprise Edition and would like to know if this applies.
This feature is designed to boost backup and restore performance. See: http://support.microsoft.com/kb/304261

i think you might mean VIA, virtual interface architecture, sometimes just called VI
don’t worry about it, not enough people were willing to adopt it
its effectively dead
look for new improved GE adapters, with tcp offload, rdma, etc
