    • Provided is a capacity monitoring method used for a computer system including one or more application computers, one or more storage systems, and a management computer. The storage system includes a physical disk and a disk controller. In the capacity monitoring method, a storage area of the physical disk belongs to a storage pool, the storage system provides a volume, and the management computer monitors a used capacity of the storage pool, judges whether or not a storage capacity required for operating the application computer for a predetermined time period is present in the storage pool based upon an increasing speed of the used capacity of the storage pool to be monitored, and executes a predetermined process operation when the storage capacity required for operating the application computer for the predetermined time period is not present in the storage pool. Accordingly, the storage pool is properly operated and managed.
    • 提供了一种用于包括一个或多个应用计算机,一个或多个存储系统和管理计算机的计算机系统的容量监视方法。 存储系统包括物理磁盘和磁盘控制器。 在容量监视方法中,物理盘的存储区属于存储池,存储系统提供卷,管理计算机监视存储池的使用容量,判断操作所需的存储容量 基于要监视的存储池的使用容量的增加速度,存储池中存在预定时间段的应用计算机,并且当在预定时间内操作应用计算机所需的存储容量时执行预定的处理操作 期间不存在于存储池中。 因此,存储池被正确地操作和管理。

    • When communications among a plurality of processors employed in a network storage system are required, any of the processors initiating a communication on the transmission side issues a request to an I/O processing apparatus, which is used for controlling a disk unit and a disk cache common to the processors, in order to allocate an area in the common disk cache as a communication buffer. At such a request, the I/O processing apparatus allocates a specific area in the common disk cache as a communication buffer and gives a notice of the allocation to the requesting processors on the transmission side. Receiving the notice, the transmission-side processors write data to be transferred into the specific area of the disk cache and, then, the reception-side processors fetch the transferred data from the specific area.
    • 当需要在网络存储系统中使用的多个处理器之间进行通信时,在发送侧发起通信的任何一个处理器向用于控制盘单元和盘缓存的I / O处理装置发出请求 为了将公共磁盘缓存中的区域分配为通信缓冲器,对于处理器是共同的。 在这种请求下,I / O处理装置将公共磁盘高速缓存中的特定区域分配为通信缓冲器,并向发送侧的请求处理器发出分配通知。 接收通知时,发送方处理器将要传送到磁盘高速缓存的特定区域的数据写入,然后接收侧处理器从特定区域取出传送的数据。
