Abstract
A file array communications transport system transports unique packets between a host computer and an adapter of a data processing platform in accordance with a file array protocol. The protocol is manifested as an exchange of these unique packets and the file array transport comprises an arrangement of logic circuits and data structures needed to exchange these packets over a tightly-coupled, low latency interface of a file array storage architecture.
Claims15
Apparatus for communicating between a host computer and an adapter of a data processing platform over an interface, the apparatus comprising:
- communication regions in host memory of the host computer that are shared by the adapter and host computer, the communication regions comprising at least one placeholder for communicating an input/output (I/O) operation;
- and
- a file array information block (FIB) referenced by the placeholder, the FIB containing information needed to execute the I/O operation between the host computer and the adapter.
