Abstract

With technological advances for storage volume size of a semiconductor memory, USB storage is made as products to support a high capacity storage. Hereby, consumers discard pint-sized USB storages which they already had, or do not use them efficiently. To integrate and unify these pint-sized USB storages as one big USB storage, we proposed Sigma Hub. It can be grouping multiple USB storages, which have each different volume size of memory storage, as logical unity Storage through USB Hub. The proposed Sigma Hub includes Sigma Controller as a core management module to unify the multiple USB storages in transaction level layer. Sigma controller can efficiently control transaction packet in Sigma Hub through a USB Storage-Integration algorithms which ensure an integrity for data read and write processes. Consequently, Sigma Hub enables the use of USB storage that is logical unity.

USB 저장장치는 반도체 메모리 저장 용량에 대한 기순 발전에 따라, 대용량 저장공간을 제공하는 제품으로 생산되고 있다. 따라서 소비자는 저장공간이 상대적으로 작은 기존 USB 저장장치를 폐기하거나, 효율적으로 사용하지 않는다. 본 논문에서는 메모리 저장 용량이 다른, 다수의 USB 저장장치를 USB 허브를 통하여 그룹화 하여 사용자가 컴퓨터에서 논리적 단일 저장공간으로 사용할 수 있는 개선된 USB 허브인 시그마 허브(Sigma Hub)를 제안한다. 제안된 시그마 허브는 다수의 USB 저장장치를 단일화하기 위한 관리 모듈로서 시그마 콘트롤러(Sigma Controller)를 포함한다. 시그마 콘트롤러는 USB 저장장치 통합 알고리즘을 통하여 트랜잭션을 제어하여 논리적 단일 저장장치 사용을 가능하게 한다.
