Abstract
The present invention relates to a kind of storage system copy link flow control realizing method, this method includes being controlled based on tentative flow control, based on priority class traffic, based on quantization congestion notification in storage system copy link flow control type（QCN）Flow control and based on intelligent flow control, when congestion occurs for storage system copy link, after storage system replication task transmitting terminal receives congestion passback message, storage system replication task transmitting terminal is sent by the good copy link flow control type of corresponding configuration and service traffics packet, to solve the problems, such as the dramatic decrease of caused copy link transmission efficiency after congestion occurs for copy link.
Description
Technical field
The invention patent relates to computer field of storage.
Background technology
Storage system refers to various storage devices, control unit and the management information by storage program and data in computer
The equipment of scheduling（Hardware）And algorithm（Software）The system formed.The main memory of computer cannot meet access speed simultaneously
Soon, the big and at low cost requirement of memory capacity, must have in a computer speed from slow to fast, the descending multistage layer of capacity
External memory, with optimal control dispatching algorithm and rational cost, constituting has the acceptable storage system of performance.
The main memory of computer cannot meet that access speed is fast, memory capacity is big and requirement at low cost simultaneously, count
Must have in calculation machine speed from slow to fast, the descending multilevel hierarchy memory of capacity, with optimal control dispatching algorithm and
Rational cost, constituting has the acceptable storage system of performance.The status of the performance of storage system in a computer is increasingly heavy
It wants, main cause is：1. von Karman architecture is built on the basis of stored program concept, accessing operation accounts for about center
Processor（CPU）70% or so of time.2. storage management and the quality of tissue influence overall efficiency.3. at modern information
Reason, such as the requirement of image procossing, database, knowledge base, speech recognition, multimedia to storage system are very high.
The business that storage system externally provides can be divided into block storage, file storage and object storage, block storage and refer at one
RAID（Redundant array of independent disks）It concentrates, one group of disc driver is added in a controller, then provides fixed size
RAID blocks are as LUN（Logical unit number）Volume.File storage is also known as NAS（Network Attached Storage：Network is attached
Belong to storage）Be a kind of by distribution, independent Data Integration it is large-scale, centralized management data center, in order to different masters
The technology that machine and application server access.Object storage object stores, also referred to as object-based storage, is for describing
It solves and the generic term of the method for processing discrete unit, these discrete units is called object.Just as file, object
Including data, but with file unlike, object there will be no hierarchical structure in a layer structure.Each object is one
In the same rank of a flat address space referred to as storage pool, an object will not belong to the next stage of another object.
Patent of invention content
The invention patent relates to a kind of storage system copy link flow control realizing method, this method replicates chain in storage system
Flow control type in road includes being controlled based on tentative flow control, based on priority class traffic, based on quantization congestion notification（QCN）Stream
Amount is controlled and is controlled based on intelligent flow, when congestion occurs for storage system copy link, storage system replication task transmitting terminal
After receiving congestion passback message, storage system replication task transmitting terminal is by the good copy link flow control type of corresponding configuration
It is sent with service traffics packet, to solve the dramatic decrease that caused copy link transmission efficiency after congestion occurs for copy link
Problem.
