A technique maintains online access to data stored in a plurality of storage devices during a hardware upgrade in which the plurality of storage devices moves between storage processor enclosures. The technique involves providing, from the plurality of storage devices, online access to the data while each storage device of the plurality of storage devices resides in a first storage processor enclosure. The technique further involves providing, from the plurality of storage devices, online access to the data while the plurality of storage devices is moved from the first storage processor enclosure to a second storage processor enclosure (e.g., transferring each storage devices one by one before triggering a rebuild process). The technique further involves providing, from the plurality of storage devices, online access to the data while each storage device of the plurality of storage devices resides in the second storage processor enclosure.

Techniques for managing a disk involve acquiring a message for an access operation for a disk, the message including a first status code at an operating system level for the access operation. The techniques further involve acquiring a second status code at a disk hardware level for the access operation if it is determined that the first status code indicates that the access operation fails. The techniques further involve determining, according to a handling policy corresponding to the second status code, whether the disk will be marked as faulty. The techniques further involve managing the disk based on a count of failed access operations for the disk if it is determined that the disk is not marked as faulty. Such techniques may quickly determine a specific reason for a failure of a disk access operation, making it possible to solve problems quickly, save time and improve the user experience.

Techniques for error detection involve injecting, to a switch of a storage system, information representing an error of at least one device to be tested of the system, such that the information representing the error is passed from an upstream port of the switch to a computing device connected with the switch, the switch being connected to the at least one device to be tested via a downstream port. The techniques further involve obtaining a handling result of the computing device on the information representing the error, and determining an error handling capability of the system at least partly by analyzing the handling result. Accordingly, slave storage devices of storage system nodes, connectors, the entire PCIe topology at the CPU level, and an NVMe bus can be tested, so that the entire logical path of the error handling can be tested, thereby improving performance and saving testing costs.

A method is described for controlling an electric motor having a rotor. The method is carried out after a shutdown of the motor has been initiated. The method includes starting a timer in a motor controller, performing regenerative braking to recapture kinetic energy from the rotor as electrical energy, and using the recaptured electrical energy from the regenerative braking to power the motor controller. If the timer in the motor controller exceeds a predetermined timer value, a flag is set in memory in the motor controller to indicate that the motor has stopped.

Techniques to control a storage system involve: determining whether available power capable of being supplied by a supplying apparatus of the storage system is less than power required by the storage system; and in response to a determination that the available power is less than the power required by the storage system, adjusting an operation parameter of the storage system based on the available power so as to match the power required by the storage system with the available power. In this way, the performance of the storage system can be at a higher level while the performance of the storage system can remain stable in a case where power of a processor is limited.

Controlling a storage system based on available power

Techniques involve: if it is determined that a power supply level of a processing unit in a normal mode in a computer system is lower than a threshold level, determining the remaining power of a battery backup unit in the computer system; and if it is determined that the remaining power is higher than the threshold power, causing the battery backup unit to supply power to the processing unit to maintain the processing unit in the normal mode. Accordingly, the performance of the computer system can be optimized and stabilized without increasing the hardware cost of the computer system or changing the power supply capability of the computer system, and the user experience of users using the computer system can be improved.

A resource allocation method for network slicing and an orchestrator, comprising: uniformly incorporating resources originally bundled statically with the base station into a dynamic resource pool; allocating, by an orchestrator, resources from among the dynamic resource pool for the network slicing based on different network slicing requirements. A static corresponding/mapping relationship between the hardware/radio resources and the base station is broken, such that hardware/radio resources (e.g., radio access network Virtual Network Function (RAN VNF), baseband unit (BBU), RRH (Remote Radio Head) as well as antenna) that originally corresponded to different base stations will be organized as an integrated and dynamic hardware/radio resource pool and reported to the orchestrator, such that the orchestrator will centrally manage all hardware/radio resources in this pool and then sufficiently utilize and dynamically orchestrate these hardware/radio resources based different needs from the network slicing.
