  • Method and system for programmable sequencer for processing I/O for various PCIe disk drives
    Patent number: 9400614
    Abstract: 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.
    Type: Grant

  • Interface for heterogeneous PCI-e storage devices
    Patent number: 8943226
    Abstract: Disclosed is a storage device interface. The storage device interface includes a plurality of PCIe device request engines. These PCIe device request engines receive I/O commands formatted for a respective one of a plurality of PCIe storage device communication standards. The storage device interface also includes a plurality of PCIe device completion engines. These PCIe device completion engines receive notifications of command completions from a plurality of PCIe storage devices that communicate using the aforementioned plurality of PCIe storage device communication standards. These notifications are validated. If an error is detected, processing of notifications of command completions associated with that device are blocked until the error is resolved. The plurality of PCIe device request engines and the PCIe device completion engines operate concurrently to process received I/O commands and received command completions.
