Abstract:
The present disclosure discloses a method for determining a drive letter, including: obtaining a number of a port connecting a redundant array of independent disk RAID controller to an exchange chip and a location number, of a disk, meeting a report condition in each RAID group under the control of the RAID controller, where the location number, of the disk, meeting the report condition is a location number, of a disk, on a preset location after location numbers of all disks included in each RAID group when each RAID group is configured, are sorted according to a preset sequence; and determining a drive letter corresponding to each RAID group according to the number of the port connecting the RAID controller to the exchange chip and the location number, of the disk, meeting the report condition in each RAID group.

Abstract:
The present invention relates to the communications field, and provides a phased array calibration method and a phased array calibration circuit. The phased array calibration circuit includes a signal obtaining module, a selector, a phase difference module, and a main signal module. The selector is configured to switch on the signal obtaining module and the main signal module; the signal obtaining module is configured to obtain a first signal according to an initial signal after the selector switches on the signal obtaining module and the main signal module; the selector is further configured to switch on the phase difference module, the signal obtaining module, and the main signal module; and the signal obtaining module is further configured to obtain a second signal according to the initial signal after the selector switches on the phase difference module, the signal obtaining module, and the main signal obtaining module.
