Embodiment

[0026] Embodiment: The present invention provides a memory pool management method of a distributed storage system, which specifically includes the following steps:

[0027] S1. The initialization of the distributed storage system starts, and the network card device is turned on;

[0028] S2. Allocate memory, register the memory pool of the distributed storage system, and record the first address and memory size of the memory pool;

[0029] S3. Taking the first address of the memory pool of the distributed storage system as an input parameter, registering the memory pool of the network card, organizing the memory pool of the network card according to the data block size of the distributed storage system and recording the offset, and returning the handle number of the network card;

[0030] S4. The initialization of the distributed storage system ends;

[0031] When the distributed storage system reads data, the following operations are performed:

[0032] S11. The underlying ...

Abstract

The invention discloses a memory pool management method for a distributed storage system, which comprises the following steps of: S1, starting initialization of the distributed storage system, and opening network card equipment; s2, allocating a memory, registering a memory pool of the distributed storage system, and recording a head address and a memory size of the memory pool; s3, taking the initial address of the memory pool of the distributed storage system as an input parameter, registering a network card memory pool, organizing the network card memory pool according to the size of a data block of the distributed storage system, recording offset, and returning a network card handle number; and S4, ending initialization of the distributed storage system. According to the method and the device, memory copies from the distributed storage memory pool to the network card memory pool and from the network card memory pool to the distributed storage memory pool can be respectively eliminated in a data reading and writing scene, so that the overhead of context switching and the like is further reduced, and the data transmission performance of a distributed storage system is improved.

Description

technical field [0001] The invention relates to a memory pool management method of a distributed storage system, belonging to the technical field of high-performance computing. Background technique [0002] In order to solve the delay of server-side data processing in network transmission, remote direct memory access (RDMA) technology is produced, which allows data to be quickly moved from a system memory storage to a remote system memory storage without any impact on the operating system. This does not require much computer processing power, and it eliminates the overhead of external memory copying and context switching, thereby freeing memory bandwidth and CPU cycles for improved application performance. RDMA has the characteristics of low latency, low load, and high bandwidth. Large-scale distributed storage systems have high requirements for network bandwidth and delay due to file operation and communication between multiple clients and servers. The traditional TCP / IP p...
