Description

A kind of method of testing based on the blade server memory voltage

Technical field

The present invention relates to computer communication field, be specifically related to a kind of problem of utilizing voltage tester to solve the high stability of blade server internal memory.

Background technology

Current server system, the blade server system of enterprise-level application particularly, requirement for Performance And Reliability is more and more higher, remove CPU, outside the hard disk, the internal memory conduct is one of important components wherein, Performance And Reliability to total system plays important effect, internal memory is from SDRAM at present, DDR, DDRII, the DDR3 of mainstream applications up till now, performance is more and more higher, capacity is also increasing, thereby it is also more and more higher to be accompanied by power consumption, and wall scroll content power consumption is near 30W, the amount of memory that the separate unit server master board adopts can reach 18, therefore for internal memory, how to guarantee the design of its voltage module, play crucial effects for the stability of whole server system.

Summary of the invention

The purpose of this invention is to provide a kind of method of testing based on the blade server memory voltage.

The objective of the invention is to realize in the following manner, is guiding with the voltage tester quality, follows the Intel standard, utilize server host board source end that the high-grade signal source of compliant is provided, the stability of testing server memory bar is guaranteed the reliable operation of internal memory, and concrete testing procedure is as follows:

1) according to the standard of Intel internal memory, defines the blade server standard, be specially the characteristic standard of 1.5V voltage and 0.75V reference voltage, comprise voltage ripple, quiescent voltage, output current value;

2) according to of the requirement of Jetec association for memory voltage, go to define the standard of memory bar, be specially the magnitude of voltage of 1.5V;

3) utilize the DDR VTT measurement jig blade server host board of USB interface to carry out the test of voltage, electric current, testing tool uses Tektronix TDS7104,1GHZ bandwidth oscillograph, probe uses Tektronix6245,1.5GHZ bandwidth, carry out voltage ripple, quiescent voltage, the test of output current value;

4) use Tektronix TDS7104,1GHZ bandwidth oscillograph carries out the memory bar test on the motherboard, the magnitude of voltage of test 1.5V.

Excellent effect of the present invention is can detect the DDR3 internal memory fast and effectively, the problem of realization raising blade server internal memory high stability.

Embodiment

The present invention utilizes Intel standard and Jedec standard to be the theory support point, is the problem that concrete check form solves the high stability of blade server internal memory with the voltage signal test, and concrete summary of the invention can be divided into following two aspects:

1) according to the standard of Intel internal memory definition, formulates the working voltage current value of mainboard internal memory and the scope of reference voltage level, use measurement jig that the DDR3 memory bar is tested then with usb function;

2) according to the standard of Jedec internal memory definition, formulate the scope of the working voltage current value of memory bar, use oscillograph that memory bar is tested then.

Concrete testing procedure is as follows:

1. according to the standard of Intel internal memory, go to define the blade server standard, be specially the characteristic standard of 1.5V voltage and 0.75V reference voltage, comprise voltage ripple, quiescent voltage, output current value

2. according to of the requirement of Jetec association, go to define the standard of memory bar, be specially the magnitude of voltage of 1.5V for memory voltage

With reference to the accompanying drawings, content of the present invention is carried out a more detailed enforcement and does an elaboration:

3. as described in the summary of the invention, at first we utilize the DDR VTT measurement jig blade server host board of USB interface to carry out the test of voltage, electric current, testing tool uses Tektronix TDS7104 (1GHZ bandwidth) oscillograph, probe uses Tektronix 6245 (1.5GHZ bandwidth), carry out voltage ripple, quiescent voltage, the test of output current value

4. secondly, the memory bar that we use Tektronix TDS7104 (1GHZ bandwidth) oscillograph to carry out on the motherboard is tested, and mainly is the magnitude of voltage of test 1.5V.

Through top detailed signal testing, we can very clearly know nonresident portion working condition in the whole blade server, meet some such as internal memory detect less than, system performance reduce, system delays problems such as machine, very clearly the orientation problem key is pointed out in those places, that link, according to phenomenon and voltage tester analysis result, find final problem place and solution then, guarantee the high stability work of whole blade server.
