Information Processing System

摘要

A system having an SMP connection made among each information processing apparatus in units of a module including a CPU, a main memory, an HDD and the like, allows use of the HDDs distributed in the system as a single disk. The SMP connection is made among information processing apparatuses each including one or more CPUs, a main memory, one or more storage devices, and a storage device controller that controls the storage device. The storage device controller in a certain information processing apparatus controls the storage device in the information processing apparatus and the storage device in another information processing apparatus. Each information processing apparatus includes a storage device switch for exclusively switching which of the storage device controller in the information processing apparatus and the storage device controller in another information processing apparatus is connected to the storage device in the information processing apparatus.
