Problems solved by technology

However, at present, the SAS port bandwidth test of RAID storage IO has always been a manual operation project, requiring a large number of human operations to participate, which inevitably leads to errors caused by human factors, resulting in inaccurate tests, long test time and low efficiency. No test log will be generated, the test control is not comprehensive enough, and the product quality cannot be guaranteed

Embodiment

[0018] The method of testing the SAS port bandwidth of the RAID storage IO in this embodiment is to test the SAS port bandwidth of the RAID type IO in the storage under linux based on FIO, using an automated script written in perl language, based on FIO, and pairing ports through SAS The test log is printed on the terminal and stored on the server at the same time, so that the test is absolutely guaranteed. The FIO is an I / Oc testing tool for benchmarking and stress / hardware verification, it supports many different types of I / O engines, such as sync, mmap, libaio, posixaio, SG v3, splice, null, network , Syslet, guasi, solarisaio, etc., it can work on block devices and files.

[0019] Attached figure 1 For the implementation flowchart of the method of testing the SAS port bandwidth of the RAID storage IO, as attached figure 1 As shown, the specific implementation process of this method is as follows:

[0020] 1. Set up a hardware test environment; after preparing materials such ...

Abstract

The invention discloses a method for testing the SAS port bandwidth of an RAID memorizer IO and relates to a memorizer testing technology. A perl language compiled automation script is used in a linux system, and the port bandwidth is tested through an SAS wire. The method mainly comprises the following steps that 1, a serial number of an I/O in the memorizer is scanned; 2, an I/O type is automatically judged, and a drive script is automatically loaded; 3, hardware detection is performed; 4, IP of upper and lower I/O is set, and the I/O is re-started after success in a system; 5, whether IP setting of the I/O succeeds or not is detected; 6, the bandwidth testing of an IO SAS port is executed. The whole testing process is automatically executed, log testing is saved, unnecessary man-machine interaction process is decreased, labor, time, cost and resources are saved, the testing efficiency and accuracy are improved, the testing cover rate is very high, and the product shipment quality is ensured.

Description

Technical field [0001] The present invention relates to memory testing technology, in particular to a method for testing SAS port bandwidth of RAID memory IO. Background technique [0002] RAID (Redundant Arrays of Independent Disks) storage is a cheap redundant array of disks that can provide an independent large-scale storage device solution. The bonus effect of using individual disks to provide data in RAID improves the performance of the entire disk system, increases the capacity and speed of the hard disk system, makes data more secure, and makes disk management easier. When any one of the disks fails, the data can still be read out. When the data is reconstructed, the data is calculated and re-placed into the new hard disk. [0003] RAID storage has block technology: write data in blocks to the disks in the array; cross technology: use cross read and write to distributed data to improve access speed; regroup technology: readdress multiple disk spaces , The data is stored in...
