Abstract: A rolling bearing limited by a magnetic field, relating to the field of mechanics and aiming at removing sliding friction existing in a rolling bearing. A method therefor is limiting relative positions between parts of a bearing by means of magnetic fields of magnets provided at the parts of the bearing, especially keeping spacings between rollers, thereby removing a cage of a rolling bearing to remove or reduce sliding friction of the rolling bearing. Some types of bearings having raceways and all types of bearings free of raceways have sliding friction completely removed to become pure rolling bearings working in a pure rolling mode. Therefore, such a rolling bearing can work normally without using a lubricating agent to become a lubricating-free, maintenance-free, energy-saving, environmentally-friendly, and pollution-free bearing, and has reduced noise and prolonged service life. In addition to applications to conventional fields, such a bearing can also satisfy requirements of special industries such as the food processing industry, space industry, low temperature industry, and high vacuum industry.

Abstract: A storage system, a storage node, and a data storage method. The storage system comprises multiple computation nodes (20a, 20b, 20c) and multiple storage nodes (30a, 30b, 30c). Each storage node comprises a hard disk (302). A client writes storage data to a memory of a first computation node, and writes a log of the data to a storage space corresponding to a first access address at a first storage node, thereby realizing storage of the data. The first storage node does not need to internally convert the first access address to another address, and can forward the first access address to a first hard disk to which the first access address belongs, such that the first hard disk stores the log on the basis of the first access address. Since an access address does not need to be converted, a data access path is shortened.
