摘要： A method and apparatus for enabling a magnetic disk storage device that stores data according to a first data structure characterized by a fixed-length disk block size to respond to input/output requests from a host that define data according to a different data structure characterized by a different fixed-length host block size. A host adapter transfers requests and data between the host and a cache memory in the magnetic disk storage device as host blocks. A disk adapter transfers requests and data between the cache memory and magnetic disks as disk blocks. CRC data and a sector number are appended to each host block in a set of disk blocks.

摘要： A method and apparatus for verifying the organization of a magnetic disk storage system in which individual storage logical volumes are grouped in sequence as components of a meta device. Data concerning the organization of the meta device is stored in each storage logical volume in a dedicated storage area and in a global memory accessible to the data processing system. Whenever the integrity of the meta device is tested, the data in the configuration file and the data in the dedicated storage area are analyzed and compared. If identity exists, integrity is assumed. If identity does not exist various errors are generated to prevent use of the storage logical volume until the problem is resolved.

摘要： Disk array storage device apparatus for enhancing the performance of an application on a data processing system that operates with a disk array storage device in which the completion of tasks associated with different transactions with one logical storage device are conditions precedent to the completion of other transactions. Specific tasks related to the one logical device are given priority over tasks related to all other logical storage devices. In a specific implementation reconnect tasks are given the highest priority with reconnect tasks from the one logical storage device being given the highest priority. A second category of tasks related to the one logical storage device can be given priority over all other tasks except reconnect tasks. All other tasks are given a priority below that of the first and second task categories.

摘要： A method and apparatus for enabling an on-line reconfiguration of striped data in a disk array storage device. A replicated copy of the striped logical device is made in parallel with host operations. A logical device with a new configuration is then substituted for access by the host application even before any data is transferred to locations within the newly configured logical device. Independent processes operating in this disk array storage device reconfigure the data transparently to any host operations while accommodating host I/O requests directed to locations in the new configuration.

摘要： For a data copying operation, data compression using constant number-of-track-groups and a thinly provisioned target device facilitates incremental updates where the size of the compressed data on the target device changes. Compressed data is written to the same LBA as the beginning of the source device chunk cluster LBA (1:1 mapping of data start). A termination string or other demarking device is used to identify space freed on the target device resulting from compression. During an incremental update only changed chunk clusters are changed, and freed space is changed accordingly if necessary.

摘要： In one aspect, a method includes providing a continuous data protection system comprising a data protection appliance, a splitter and source volumes on a source side that are replicated to target volumes of a storage array on a target side by using a journal of write transactions; and enabling, in an image access mode, a rolling back of the target volumes on the target side from a first point in time to a selected point in time so that the target volumes contain data for the selected point in time. The selected point in time is earlier than the first point in time and the rolling back includes undoing write transactions in the journal subsequent to the selected point in time; enabling generation of a virtual snapshot of the target volumes for the selected point in time after rolling back the target volumes to the selected point in time; and enabling a user to access the virtual snapshot in the storage array at the selected point in time.

摘要： Example embodiments of the present invention provide asynchronous splitting of IOs from a storage array, such as a Symmetrix by EMC Corporation of Hopkinton, Mass. to a replication appliance, such as RecoverPoint by EMC Corporation of Hopkinton, Mass. The storage array may receive a plurality of IOs from a host and may store a record (e.g., in an ordered table) associated with the IOs. At a later time, the storage array may provide the IOs according to the record associated with the IOs. For example, the storage array may receive a plurality of Small Computer System Interface (SCSI) Command Descriptor Blocks (CDBs) from one or more hosts and receive data associated with the CDBs. The storage array then may write the data to respective locations in storage and create entries in the ordered table according to the order in which the CDBs were received.
摘要翻译：本发明的示例实施例提供了从存储阵列（例如，由Mass Corporation的Hopkinton的EMC Corporation的Symmetrix）到复制设备（例如，由Mass Corporation的Hopkinton的EMC Corporation的RecoverPoint）异步分割IO，存储阵列可以接收来自主机的多个IO，并且可以存储与IO相关联的记录（例如，在有序表中）。稍后，存储阵列可以根据与IO相关联的记录来提供IO。例如，存储阵列可以从一个或多个主机接收多个小型计算机系统接口（SCSI）命令描述符块（CDB），并且接收与CDB相关联的数据。然后，存储阵列可以将数据写入存储器中的相应位置，并根据CDB接收的顺序在有序表格中创建条目。
