Computer engineering is a branch of engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software. Computer engineers usually have training in electronic engineering (or electrical engineering), software design, and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers, microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work but also how they integrate into the larger picture.

Software update method, apparatus and system

A system for remotely updating software on at least one electronic device connected to a network. The electronic devices have a non-volatile rewritable storage unit divided into at least two partitions, one of which will contain core firmware and the other of which will contain auxiliary software. When an update is received at the device, the updated core firmware is written to overwrite the partition in the rewritable storage unit that contained the auxiliary software. When this is completed and verified, the previous version of the core firmware stored in the storage unit is disabled from execution by the device. Next, the updated auxiliary software is written to overwrite the old version of the core firmware. When this write is complete, the device determines a suitable time for it to be rebooted to execute the updated software. In another embodiment, the present core firmware in the device is copied from the partition it is in to the other partition, overwriting the auxiliary software stored there. The new core firmware received to update the device is overwritten into the first partition, the old copied core firmware being present in case of an upgrade failure, and upon a successful update of the first partition, the auxiliary software is written to the second partition, overwriting the copied old core firmware. In this manner, the position of the core firmware and auxiliary software within the partitions is preserved during normal operation of the device.

Method for managing storage system using flash memory, and computer

To facilitate the management of a storage system that uses a flash memory as a storage area. A controller of the storage system provided with a flash memory chip manages a surplus capacity value of the flash memory chip, and transmits a value based on the surplus capacity value to a management server, on the basis of at least one of a definition of a parity group, a definition of an internal LU, and a definition of a logical unit. The management server displays a state of the storage system by using the received value based on the surplus capacity value.
