Abstract: A method for monitoring hard disks, implemented in an electronic device, includes sequentially detecting a number of hard disk codes of hard disks recorded by a host bus adapter, and determining whether each hard disk code has a drive letter assigned; if one hard disk code is determined to not have a drive letter assigned, writing a first mark corresponding to the hard disk code in a register of the host bus adapter. When detection of all hard disk codes is completed, transmitting the first marks written in the register to a CPLD interface and detecting whether each hard disk corresponding to the first mark is in place. If one hard disk corresponding to the first mark is found to be in place, controlling the hard disk to output an alarm based on the first mark.

Abstract: In some examples, for migrating data from a first storage system to a second storage system, a system creates a proxy at the first storage system to direct write requests received at the first storage system to the second storage system, initially sets a cache in the first storage system to a first state in which the cache stores write data for first write requests, and changes a state of the cache from the first state to a second state in which write data for second write requests bypasses the cache and are directed by the proxy to the second storage system.

Abstract: An array of interconnected memory cells for storing therein a fractional-quantum-Hall-effect droplet whose state is controllable using voltages applied to the cell electrodes. In an example embodiment, the memory cells are arranged and linked together such as to reduce the geometric size of the array, e.g., compared to that of a linear array having the same number of memory cells. For example, one or more wheel-and-spokes arrangements of the memory cells can be used for this purpose. The smaller geometric size of the array can result in better coherence across the droplet confined therein, which can advantageously be used to improve the reliability and/or performance of the corresponding quantum-computing device.
