Techniques involve: acquiring, through a first downstream port of a first switch of a data storage system, information indicating an error of a storage device array from a second switch of the data storage system, wherein the first switch and the second switch are connected to the storage device array and the first downstream port is connected to a second downstream port of the second switch; executing, based on the acquired information, actual actions intended for solving the error; and in response to the executed actual actions failing to match with expected actions for the error, issuing an alarm indicating failure of processing the error.

Method for detecting data storage system, device and data storage system

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.

Power supply method, electronic device, and computer program product

Techniques for the storage management involve, in response to detecting that a storage device is plugged into the storage system, determining, at a computing device of a storage system and based on attributes of the storage device, a target interface device matching the storage device from a plurality of types of interface devices in the storage system, the interface device managing the storage device having attributes matching one of the plurality of types; determining an association between the storage device and the target interface device; and generating, based on the association, information characterizing a state of the storage device in the computing device. In this way, it is possible to support at least two different types of disks in the existing storage system, improving the compatibility and scalability of the system.
