OceanStor 6800 V3, Power calculator , Power deviation

Publication Date:  2016-06-26 Views:  265 Downloads:  4
Issue Description

After customer installs storage devices 6800 V3, the actual power consumption in site is less than the minimum value of power consumption which is calculated by Power calculation tool in the previous.

Alarm Information

The actual deviation of power consumption


Handling Process

According to running data of the local equipment, to confirm the information of the hard disk:


According to the actual generation of the hard disk, to re calculate power consumption, the theoretical power consumption is: 


Root Cause

Support web site provides one power consumption calculator for Huawei storage products:

According to the user's choice of hard disk model, number and the type of the machine, the calculator calculates the power consumption of equipment.

According to the calculation, now the device power consumption is as follows: 

According to the typical power consumption calculation, the minimum power consumption value is 3781W, but the cabinet average power consumption 4.7KVA is bigger than the actual cabinet power consumption 3.40KVA:


Huawei storage products power calculator is refer to the upper limit of the same type disk’s power consumption to calculate the disk power, in the actual situation: many hard disk manufacturers and their hard disk batch have the same disk code, which these disk’s power are differences. Due to the improvement in the manufacturing process, the new generation of hard disk generally has less power consumption than the old generation. Customer service network is using the latest generation of the hard disk, so the actual power consumption of the cabinet is relatively low.


Huawei product storage power calculator is refer to the same disk type’s power upper limit value, we can according to the actual configuration in site, to calculate hard disk’s special generation of power consumption for the actual operation.  


Support web site provides one power consumption calculator for Huawei storage products. The calculator is usually adopted in the upper limit of the device’s power consumption (different devices have different manufacturing technology in different batches or generations, and the actual power consumption is not the same). Therefore, the value calculated by tool has some different with the actual which is a normal phenomenon.
