The present invention proposes a dynamic resources allocation method and system for guaranteeing tail latency SLO of latency-sensitive applications. A plurality of request queues is created in a storage server node of a distributed storage system with different types of requests located in different queues, and thread groups are allocated to the request queues according to logical thread resources of the service node and target tail latency requirements, and thread resources are dynamically allocated in real time, and the thread group of each request queue is bound to physical CPU resources of the storage server node. The client sends an application's requests to the storage server node; the storage server node stores the request in a request queue corresponding to its type, uses the thread group allocated for the current queue to process the application's requests, and sends responses to the client.

The present application is applicable to the field of smart terminal technologies, and a Bluetooth connection method and device and a smart terminal are provided. The method includes: searching, by a terminal device, for a dual-mode Bluetooth device and establishing a connection relationship in a first Bluetooth mode with the dual-mode Bluetooth device; obtaining identification information of the dual-mode Bluetooth device; and establishing a connection relationship in a second Bluetooth mode with the dual-mode Bluetooth device according to the identification information.

Bluetooth connection method, device and smart terminal

A data operating method, device, and system are provided and relate to the computer field, so as to resolve a prior-art problem of low efficiency of performing a data operation on a block device by a CPU. The method includes: receiving an operation instruction sent by a CPU; when the operation instruction is a read instruction, reading a first data block in the block device and returning to-be-read data in the first data block to the CPU; or when the operation instruction is a write instruction, writing, into a cache, to-be-written data indicated by the write instruction, and writing, into the block device, a second data block that includes the to-be-written data. The method is used to operate data in a block device.

Data operating method, device, and system

A data operating method, device, and system are provided. The method includes: receiving an operation instruction sent by a CPU; when the operation instruction is a read instruction, reading a first data block in the block device and returning to-be-read data in the first data block to the CPU; or when the operation instruction is a write instruction, writing, into a cache, to-be-written data indicated by the write instruction, and writing, into the block device, a second data block that includes the to-be-written data. The method is used to operate data in a block device.

A data caching method and a computer system are provided. In the method, when a miss of an access request occurs and a cache needs to determine a to-be-replaced cache line, not only a historical access frequency of the cache line but also a type of a memory corresponding to the cache line needs to be considered. A cache line corresponding to a DRAM type may be preferably replaced, which reduces a caching amount in the cache for data stored in a DRAM and relatively increase a caching amount for data stored in an NVM. For an access request for accessing the data stored in the NVM, corresponding data can be found in the cache whenever possible, thereby reducing cases of reading data from the NVM. Thus, a delay in reading data from the NVM is reduced, and access efficiency is effectively improved.
