摘要： A storage control system judges whether the data pattern of data exchanged with a higher-level device (hereafter “data”) conforms to one or a plurality of write-excluded data patterns comprised in write-excluded data pattern information prepared in advance. If a negative judgment result is obtained, the storage control subsystem stores the data in a logical device formed on a disk storage device. If, on the other hand, a positive judgment result is obtained, the storage control subsystem erases the data without storing in a logical device.
摘要翻译：存储控制系统判断与上级装置（以下称为“数据”）交换的数据的数据模式是否符合预先准备的写入排除数据模式信息中包含的一个或多个写入排除数据模式。如果获得否定判断结果，则存储控制子系统将数据存储在形成于盘存储装置上的逻辑装置中。另一方面，如果获得肯定判断结果，则存储控制子系统在不存储在逻辑设备中的情况下擦除数据。

摘要： A multiple disk system comprises plural physical drives organized as plural groups of disks. Each group is accessed as a plurality of logical volumes. One of the logical drives is considered a primary volume and one or more other logical volumes are considered as secondary volumes, which together constitute a mirroring group. Data contained in a memory records such organization. The data is consulted to select a secondary volume when the disk group containing a primary volume fails.

摘要： A cluster computing system, comprises: a production host group; a standby host group coupled to the production host group by a network; and a remote mirror coupled between the production host group and the standby host group, the remote mirror including a production site heartbeat storage volume (heartbeat PVOL) and a standby site heartbeat storage volume (heartbeat SVOL) coupled by a remote link to the heartbeat PVOL, with the production host group configured to selectively send a heartbeat signal to the standby host group by use of at least one of the network and the remote link. A method of checking for failure in a cluster computing system, comprises: generating a heartbeat signal from a production host group; selectively sending the heartbeat signal to the standby host group from the production host group by use of at least one of a network and a remote link; and enabling the standby host group to manage operations of the cluster computing system if an invalid heartbeat signal is received by the standby host group from the production host group.

摘要： A storage system maintains a journal of journal entries and at lease one snapshot of one or more data volumes. By assigning a unique sequence number to journal and snapshot, it is easy to find a journal which can be applied to the snapshot. A technique is described for detecting an overflow condition of running out of journal space and recovering the journal space.
