Problems solved by technology

However, when updating the firmware of the disk, the storage subsystem 12 must be connected to the HBA or the RAID controller 161, and they send ATA (or SCSI) to the SATA (or SAS) disk electrically coupled to the SAS expander 122. ) command to update the firmware of the disk, and only one disk can be updated at a time
If the firmware of the N disks in the storage array 124 is to be updated, the command needs to be sent N times, and the corresponding firmware also needs to be sent N times, resulting in low firmware update efficiency of the disks.

Abstract

The invention provides updating device and updating method of magnetic disk firmware. The updating device of the magnetic disk firmware comprises an SAS (Serial Attached SCSI) expander and a nonvolatile memory, wherein the SAS expander comprises an expander connecting router and an embedded microprocessor, the expander connecting router is used for connecting an SATA (Serial Advanced Technology Attachment) magnetic disk and an SAS magnetic disk, the embedded microprocessor is electrically coupled with the expander connecting router, and an SATA host controller driving program and an SCSI (Small Computer System Interface) starter driving program are loaded in the embedded microprocessor; and the nonvolatile memory is electrically coupled to the embedded microprocessor and used for storing the magnetic disk firmware to be updated, the SATA host controller driving program or the SCSI starter driving program is selectively called by the magnetic disk firmware through the embedded microprocessor and sent to a specific magnetic disk for firmware updating through the expander connecting router. The invention can improve the updating efficiency when carrying out firmware updating of the magnetic disk.

Description

technical field [0001] The invention relates to the field of disk storage, in particular to a disk firmware update device and a disk firmware update method. Background technique [0002] see figure 1 , which shows an existing disk storage system 10, which includes a storage subsystem 12 and a server host (Server Host) 16, and the storage subsystem 12 connects a small computer system interface (Serial Attached SCSI, below) Both are referred to as SAS for short) The cable 14 is electrically coupled to the server host 16 . Wherein, the server host 16 includes a host bus adapter (HBA for short) or a redundant array of independent disks (RAID for short) controller 161 . The storage subsystem 12 includes a SAS expander 122 and a storage array 124 installed in an Enclosure; the storage array 124 includes a Serial Advanced Technology Attachment (Serial Advanced Technology Attachment, hereinafter referred to as SATA) disk and SAS The disk establishes a communication connection wit...
