    摘要： A unified storage system for executing a variety of types of storage control software using a single standardized hardware platform includes multiple storage control modules connected to storage devices for storing data related to input/output (I/O) operations. A first type of storage control software is initially installed and executed on a first storage control module for processing a first type of I/O operations. A management module replaces the first type of storage control software by installing a second type of storage control software onto the first storage control module. When the second type of storage control software is installed and executed, the first storage control module processes a second type of I/O operation, different from the first type of I/O operation. Control of volumes originally accessed by the first storage control module may be transferred to a second storage control module having the first type of storage control software installed.

    摘要翻译： 用于使用单个标准化硬件平台执行各种类型的存储控制软件的统一存储系统包括连接到存储设备的多个存储控制模块，用于存储与输入/输出（I / O）操作有关的数据。 首先在第一存储控制模块上安装并执行第一类型的存储控制软件，以处理第一类型的I / O操作。 管理模块通过将第二类型的存储控制软件安装到第一存储控制模块来代替第一类型的存储控制软件。 当安装并执行第二类型的存储控制软件时，第一存储控制模块处理与第一类型的I / O操作不同的第二类型的I / O操作。 最初由第一存储控制模块访问的卷的控制可以被传送到具有安装了第一类型的存储控制软件的第二存储控制模块。

    摘要： Backup and restore operations are made possible in a storage system that has dynamic chunk allocation (DCA) capability. In a DCA storage system, a chunk of physical storage area is not allocated to a segment of a volume until a write command is received targeting the segment of the volume. During a restore operation of the volume in the DCA storage system, the wasting of storage capacity when a backup image of the volume is restored is mitigated by preventing allocation of physical storage areas to segments of restore data that are only void data.

    摘要： The system is composed of the storage apparatuses with dynamic chunk allocation capabilities, the centralized management computer. Some storage apparatuses have the extra HDDs or volumes for providing extra capacity (extra chunks), which are concealed by a secret key. The storage apparatus with the closed segment has the key management program and key management table. The centralized management computer has the storage on demand management program, the pending request table, the priority table and the master key table. The storage apparatus may connect to the other storage apparatuses for sharing the extra capacities in the closed segment. The storage apparatus issues the chunk addition request to the centralized management computer. The centralized management computer provides a key according to the priority table and the master key table. The centralized management computer may provide the key according to the chunk consumption rate reported by the storage apparatus and/or remaining capacity in the other storage apparatuses.
