摘要： An apparatus, system, and storage medium are disclosed for utilizing data protection by a storage device to minimize loss of sensitive data on a storage medium. The apparatus includes a monitor module, a verification module, and a process module. The monitor module recognizes a write-type command from a host connected to an electronic data storage device. The verification module determines a presence of a passkey associated with the write-type command. The process module processes the write-type command according to the determination of the presence of the passkey. The apparatus, system, and storage medium provide protection of sensitive data at the device level so that a designated protected area on the electronic data storage device is protected against an inadvertent data overlay.

摘要： A database management system ensures consistency between primary and mirrored backup copies of a database, despite occurrence of a suspending condition interrupting the normal process of mirroring the primary database. One or more primary controllers are provided, each having a data storage unit with multiple primary data storage devices. Multiple secondary controllers each have multiple associated secondary data storage devices, each secondary controller being coupled to one primary controller. One or more primary databases reside on the primary devices, with a corresponding number of secondary databases residing on the secondary devices. Each secondary database mirrors a corresponding primary database. Either a host, attached to a primary controller, or one of the primary controllers itself, maintains a map cross-referencing each primary and secondary database with the primary and secondary devices containing portions thereof. If a predefined “suspending condition” affecting data mirroring occurs, the host or primary controller consults its map to identify all primary and secondary devices affected by the condition. Then, each primary controller stops all ongoing and future read/writes with each of its affected primary devices. Each primary controller also directs each secondary controller having an affected secondary device to stop mirroring the primary databases stored on that device. Then, the primary controller starts intermediate change recording and resumes read/writes with its primary devices. When the suspending condition ends, each primary controller applies the appropriate logged changes to its secondary database(s) and then reactivates each secondary database.

摘要： In a system including a host, a primary storage subsystem coupled to the host, a cache coupled to the host and separate from the primary storage system, a secondary storage subsystem, and a data mover coupling the primary and secondary storage systems, data is temporarily cached for future storage in the primary storage subsystem so as to preserve timestamp information and maintain data consistency for asynchronously mirroring the data at a secondary subsystem.

摘要： A method for sending a message from one host (16) to at least one other host, both of which are attached to a hardware subsystem (12) that is bidirectionally coupled to a mass data storage unit (14) includes (a) transferring a Send Message command through a channel (18) from a first attached host to the hardware subsystem, the Send Message command having at least one second attached host as an intended recipient; (b) buffering (20) at least a message payload portion of the Send Message command at the hardware subsystem and generating an unsolicited interrupt in the at least one second attached host; and (c) in response to the unsolicited interrupt, transferring a Request Message command through a channel from the at least one second attached host to the hardware subsystem for obtaining at least the message payload portion buffered at the hardware subsystem. The Send Message command may be a point-to-point message having a single other attached host as an intended recipient, or it may be a point-to-multipoint message having a plurality of other attached hosts as intended recipients. The hardware subsystem need have no knowledge of the message contents sent between hosts.
摘要翻译：一种用于从一个主机（16）向至少一个其他主机发送消息的方法，它们都连接到双向耦合到大容量数据存储单元（14）的硬件子系统（12），包括：（a）通过通道（18）从第一个连接的主机发送消息命令到硬件子系统，发送消息命令具有至少一个第二附加主机作为预期接收者; （b）至少在所述硬件子系统缓冲（20）所述发送消息命令的消息有效载荷部分并在所述至少一个第二附加主机中产生非请求中断; 以及（c）响应于所述主动中断，通过信道将所述请求消息命令从所述至少一个第二附加主机传送到所述硬件子系统，用于至少获得在所述硬件子系统缓冲的所述消息有效载荷部分。发送消息命令可以是具有单个其他附加主机作为预期接收者的点到点消息，或者它可以是具有多个其他附加主机作为预期接收者的点对多点消息。硬件子系统不需要知道主机之间发送的消息内容。
