Updating techniques for memory of a chassis management module

Abstract

A technique for data roll-back includes in response to a first external static memory device being coupled to a first chassis management module and the first chassis management module being coupled to a middle plane board, determining whether the first external static memory device operates normally. In response to the first external static memory device operating normally, a controller of the first chassis management module writes data in the first external static memory device into a non-volatile memory of the first chassis management module to perform data roll-back.

Description

[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 465,248 entitled “TECHNIQUES FOR UPDATING MEMORY OF A CHASSIS MANAGEMENT MODULE,” filed Aug. 21, 2014, which claims priority to Taiwanese Patent Application 102130228, entitled “ELECTRONIC APPARATUS AND DATA ROLLING BACK METHOD THEREOF,” filed on Aug. 23, 2013. The disclosure of U.S. patent application Ser. No. 14 / 465,248 is hereby incorporated herein by reference in its entirety for all purposes.BACKGROUND[0002]The disclosure relates to updating memory and, more specifically, to techniques for updating memory of a chassis management module.[0003]Each of a wide variety of conventional electronic apparatuses consists of components arranged in an array. As one example, a blade server system comprises a plurality of blade servers arranged in an array. The blade server system usually has a whole chassis and provides various functions, such as power supply, computation, communication, and heat dissipation, in...

AI Technical Summary

Benefits of technology

The patent text describes a technique for data roll-back in a computer system. The technique involves connecting an external memory device to a chassis management module and a middle plane board. The operational status of the external memory device is determined and, if it operates normally, data is written from the external memory device into a non-volatile memory of the chassis management module for roll-back purposes. The technical effect of this technique is to enable data roll-back in a computer system without compromising the stability and reliability of the system.

Problems solved by technology

Persons skilled in the art understand that active components mounted on a circuit board are susceptible to being damaged and becoming unreliable, thereby shortening the service life of the circuit board.

It is difficult to perform maintenance operation on the middle board in front or back of the chassis.

Furthermore, when the middle board is damaged, it is difficult and inconvenient to read the data in the non-volatile memory of the middle board.

As such, the serviceability of the conventional middle board is unsatisfactory in particular due to the non-volatile memory or other active components in use.

The short service life of the conventional middle board causes many technical support problems.
