Abstract

The invention discloses a system for realizing collection and playback of an input / output trace (I / O Trace) under a distribution environment. The system comprises an I / O Trace collection and playback control unit, an I / O Trace acquisition unit and an I / O Trace playback unit, wherein the I / O Trace collection and playback control unit is mainly used for managing a tester node; the I / O Trace collection unit and the I / O Trace playback unit are mainly used for acquiring host information, registering from a master control console, receiving a control command of the master control console and performing corresponding Trace collection and playback operation; and the problem of uncontrollability of an I / O request in the prior art is solved, and the generated Trace is inconvenient for the evaluation of a memory system, so that an I / O Trace collection and playback system which guarantees controllability of the I / O request and is convenient for design and the evaluation of the memory system is provided.

Description

technical field [0001] The invention relates to the field of computer storage, in particular to a system and method for realizing I / OTrace collection and playback in a distributed environment. Background technique [0002] With the development of computers, the storage system is now at the core of the computer system. In the actual application environment, strict requirements are put forward for the data processing speed, reliability and security of the storage system. For any kind of storage system, it has its own advantages and disadvantages. Therefore, testing the storage system in the actual application environment can evaluate the tested system more objectively and fairly. The best environment for testing the storage system. [0003] A storage unit test method and system thereof are disclosed in Chinese patent document CN1945747B, the test method includes selecting a storage unit test type; generating a corresponding test excitation signal according to the selected tes...
