Abstract
Embodiments herein describe techniques for establishing data constructs for a data device that enable communication between a host and a shared adapter. A shared adapter facilitates communication with one or more hosts coupled to a NIC. To do so, a host can establish the data device in each operating system that wishes to communicate with the shared adapter. This can include establishing data constructs such as storage block pages, queue indexes, and interrupt registers in the host memory. The host can then transmit a queue description record (QDR) to the shared adapter so the adapter can configure the queues and has the addresses of the data constructs in the host memory.
