Abstract

A system and method can support input/output (I/O) virtualization in a computing environment. The system can comprise a chip, which is associated with a server on a network fabric. Additionally, the chip is associated with an external memory that contains a plurality of packet buffers. Moreover, an on-chip memory maintains a state of one or more packets that contain disk-read data received from a physical host bus adaptor (HBA). Furthermore, the chip operates to en-queue said one or more packets in the plurality of packet buffers on the external memory, read out said one or more packets from the external memory based on the state of said one or more packets, and send said one or more packets to the server.

First claim

What is claimed is:

1. A system for supporting input/output (I/O) virtualization in a computing environment, comprising:
a chip, which is associated with a server on a network fabric, wherein the chip is associated with an external memory that contains a plurality of packet buffers;
an on-chip memory, which maintains state of one or more packets that contain disk-read data received from a physical host bus adaptor (HBA), and
wherein the chip operates to
en-queue said one or m…
