NI-VISA does not present a VXI-11 compatible server interface. So the short answer to your question is 'no'. However, there are several options for making your server system available remotely:
1) Use remote NI-VISA server, which exposes the NI-VISA resources through an alternate and more powerful protocol that allows you to use the entire VISA API. The server makes VISA resources accessible to any NI-VISA client version 3.0 or higher.
2) Use NI-Device to write a translator application that you run on your server. NI-Device is something that an instrument vendor would typically implement inside their firmware, to make the device natively support VXI-11, but it is also valid for you to use in this case as a translator. NI-Device is a separate packag
e available for purchase from NI.
3) If you are using LabVIEW, consider other remoting protocols like DataSocket or remote VIs.
Hope this helps.
