METHOD AND SYSTEM FOR PROGRAMMABLE SEQUENCER FOR PROCESSING I/O FOR VARIOUS PCIe DISK DRIVES

摘要

Disclosed is a system and method for using a programmable sequencer to produce a required command for a particular standard, or format, being used by the PCIe disk drive. A PCIe disk drive may support a different standard, or format. A mix of any number of different standards, or formats, is permitted in the system and method. For each message, a different set of instructions can be selected for the conversion process.

1. A method of converting a message, said message comprising a Device ID, from one of a host and firmware, said method comprising:
retrieving, by a programmable device, code from a storage device; monitoring an input buffer for a message from said host; if said input buffer contains a message from said host, retrieving, by said programmable device, information from a configuration queue by using said Device ID; and converting said message into one of at least two formats by using said information for one of a plurality of Peripheral Component Interconnect Express (PCIe) disk drives with said programmable device using said information from said configuration queue.
