Modification of small computer system interface commands to exchange data with a networked storage device using at attachment over ethernet

Abstract

A process executed by a computing device uses commands having a first format to exchange data through a network with a storage device configured to execute commands having a second format. A storage device controller identifies a command type associated with a command received from the process and identifies one or more physical memory addresses associated with the command. The storage device controller identifies a command having a second format associated with the received command and generates a network request including the command having the second format, the one or more physical memory addresses, a device identifier associated with the storage device and a tag. The network request is transmitted through a network to the storage device which executes the command having the second format. For example, an AoE request including an ATA command is generated from a received SCSI command.
