Description

네트워크 저장장치 및 그 제어방법Network storage device and control method
본 발명은 저장장치에 관한 것으로서, 보다 상세하게는 네트워크상에서 사용하는 저장장치와 이를 제어하는 방법에 관한 것이다.The present invention relates to a storage device, and more particularly, to a storage device used in a network and a method of controlling the same.
일반적으로, 네트워크 저장장치(Network Attatched Storage; NAS)는, 네트워크에 접속되도록 특화된 파일서버로서, 네트워크상에서 사용되는 저장장치이다. 네트워크 저장장치(NAS)는 이더넷이나 TCP/IP와 같은 전통적인 LAN 프로토콜을 사용하며, 오직 유닉스의 NFS와 도스/윈도우의 SMB와 같은 파일 입출력 요청만을 처리한다. In general, a network storage device (NAS) is a file server that is specialized to be connected to a network and is a storage device used on a network. Network Storage (NAS) uses traditional LAN protocols such as Ethernet or TCP / IP, and only handles file I / O requests such as UNIX NFS and SMB on DOS / Windows.
네트워크 저장장치(NAS)는 일반적으로 상시동작하므로, 전원이 지속적으로 투입되며, 따라서 중앙처리장치(Central Processing Unit; 'CPU'라 함)가 항상 동작한다. 따라서, 전력소모량을 최소화하기 위해 저성능 및 저전력의 CPU가 많이 사용되고 있다. Since network storage (NAS) is generally operated always, power is continuously supplied, and thus a central processing unit (CPU) is always operated. Therefore, low-performance and low-power CPUs are frequently used to minimize power consumption.
그러나, 최근 네트워크 저장장치(NAS)의 기본기능인 네트워크 저장장치로서의 서비스 이외에, 멀티미디어 서비스에 대한 요구가 증가하고 있고, 따라서, 종래의 저성능 CPU 만으로는 이러한 멀티미디어 서비스를 제공할 수 없는 한계가 나타나게 되었다.However, in recent years, there is an increasing demand for multimedia services in addition to services as a network storage device, which is a basic function of a network storage device (NAS). Accordingly, a limitation in that such a multimedia service cannot be provided by a conventional low-performance CPU alone appears.
　이러한 한계를 해결하기 위하여, 고성능 CPU를 네트워크 저장장치(NAS)에 사용할 경우, 상시 동작하는 네트워크 저장장치(NAS)의 특성상 많은 전력을 소비하게 되는 큰 문제점이 있다.In order to solve this limitation, when a high-performance CPU is used for the NAS, there is a big problem in that it consumes a lot of power due to the characteristics of the NAS.
　즉, 고성능의 CPU가 필요한 서비스, 예를 들어, 멀티미디어 코덱변환(transcoding)이나 스트리밍 서비스 등은 저성능 CPU에서 고성능 CPU로 서비스를 요청하여 고성능 CPU에서 이를 처리하고, 저성능 CPU는 결과만을 수신하도록 구성하는 것이 가능하지만, 이 경우, 고성능 CPU의 전원이 항상 온인 상태에서 저성능 CPU의 요청을 기다려야 하므로, 상당한 전력소모를 야기하는 문제점이 있다.In other words, services that require a high-performance CPU, such as multimedia codec transcoding or streaming services, request services from the low-performance CPU to the high-performance CPU, process them in the high-performance CPU, and receive the results only. Although it is possible to configure, in this case, since the power of the high-performance CPU is always on, the low-performance CPU needs to be waited for, resulting in considerable power consumption.
본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 제안된 것으로, 고성능 CPU와 저성능 CPU를 결합하고, 두 CPU의 전원을 제어하여, 효율적으로 멀티미디어 서비스를 수행하는 네트워크 저장장치(NAS)와 그 제어방법을 제공하는데 그 목적이 있다.The present invention has been proposed in order to solve the above problems, a network storage device (NAS) that combines a high-performance CPU and a low-performance CPU, and controls the power of the two CPUs to efficiently perform a multimedia service and its control The purpose is to provide a method.
