Embodiment Construction

[0017] The present invention will be described in detail below.

[0018] The method for assessing the impact of the server's own vibration on disk performance includes the following steps:

[0019] (1) Build a baseline performance data test platform as the baseline test platform, and use the baseline platform, iometer under windows, to perform disk performance tests;

[0020] (2) Restore the baseline platform to the standard server;

[0021] (3) Set different fan speeds to collect and process disk performance data.

[0022] In the step (1), the baseline test platform uses a standard server for modification or borrows tooling, removes the hard disk from the server, fixes it on an iron fixture 10 times the weight of the hard disk, and uses a non-standard double-male hard disk interface The cable connects the hard disk to the hard disk backplane. In this way, the hard disk is fixed outside the server, and the resonance generated by the rotation of the cooling fan of the server...

Abstract

The invention relates to a method for assessment of influences of server vibration on performances of a magnetic disk. The method includes: constructing a baseline performance data test platform serving as a baseline test platform, and adopting the baseline test platform and iometer under windows for testing performances of the magnetic disk; restoring the baseline platform to a standard server; setting different fan rotation speeds to collect and process data of the performances of the magnetic disk. The method for assessment of the influences of server vibration on the performances of the magnetic disk has the advantages that a hard disk is fixed outside the server by simple modification of a standard server, resonance generated by rotation of a heat radiation fan of a server system and high-speed rotation of the hard disk is avoided, data of the performances of the magnetic disk can be accurately measured under different duty ratios of the fan, and a basis is provided with design and modification of the server.

Description

technical field [0001] The invention relates to the technical field of computer testing, in particular to a method for evaluating the influence of server vibration on disk performance. Background technique [0002] With the continuous development of IT technology, traditional information services and increasingly powerful cloud computing services have higher and higher performance requirements for servers. As a server product provider, disk performance testing is even more essential. [0003] As we all know, any server must have its cooling system, including CPU active radiator and power supply cooling. In these cooling systems, the fans in these cooling systems rotate at high speed, which will inevitably cause slight vibration of the political system; in addition, a There will be multiple hard disks in the server, and several hard disks will vibrate when they rotate at a higher speed, and the vibration frequency is the same, and resonance will be generated to amplify the v...
