摘要： Disclosed is a system for managing data in cache. A list of data entries in a first memory area has a first end and a second end, such as a most recently used (MRU) end and least recently used (LRU) end. A first pointer addresses a data entry in the list and a second pointer addresses another data entry in the list that is not at the first and second ends. Data from a second memory area is provided to add to the list. A determination is made as to whether the provided data to add to the list is one of a first type and second type of data, such as sequentially accessed data or non-sequentially accessed data. The provided data is stored in the first memory area as a new data entry in the list. The first pointer is modified to address the new data entry after determining that the provided data is of the first type. After determining that the provided data is of the second type, the second pointer is processed to determine where to add the new data entry to the list between the first and second ends.

摘要： A data storage system and method for securely storing data includes (a) a host CPU; (b) a non-volatile storage (NVS) memory for storing data; (c) a processor, the processor being coupled to the host CPU and the NVS memory and monitoring availability of space in the NVS memory and in a non-volatile buffer (NV-Buffer); and (d) the NV-Buffer, the NV-Buffer being coupled to the host CPU, the NVS memory, and the processor, upon receiving a request to write data into the NVS memory, the host CPU storing data to be transferred to the NVS memory into the NV-Buffer, and upon receiving a confirmation message that data of a write operation to the NV-Buffer is committed, the NV-Buffer transferring the data to the NVS memory. The NVS memory includes a fast dump space for storing data transferred from the NV-Buffer when a main power is down and for restoring back data from the NVS memory to the NV-Buffer when the power is up. The NV-Buffer is a fast drain buffer and is equipped with a backup power source sufficient to hold up a power needed to transfer the data when the power is down.

摘要： A method and system for enhancing the efficiency of communication between one or more host computers and a storage system controller during a data search within either the associated storage systems or within the storage system controller itself. A storage system controller, coupled to one or more host computers via multiple communication channels, is utilized to control access to one or more direct access storage devices. A host computer authorizes the storage system controller to search within a range of data locations within the storage system, sets an initial location from which the data search will begin, and specifies a key field argument to search for. The host computer then permits the storage system controller to independently search the authorized range of data locations within the storage system or within cache memory within the storage system controller. The storage system controller examines multiple records within the authorized range of data locations to locate a desired record associated with the key field argument and presents a status report to the host computer only after the desired record is located or the entire range of data is searched and the desired record was not located. Allowing the storage system controller to independently search records and report status only after completion of an attempt to find a desired record within an authorized range of records minimizes communication overhead. Reducing the number of status reports presented over the communication channel enhances communication efficiency.
摘要翻译：一种用于在关联的存储系统内或存储系统控制器本身内的数据搜索期间增强一个或多个主计算机与存储系统控制器之间的通信效率的方法和系统。利用经由多个通信信道耦合到一个或多个主计算机的存储系统控制器来控制对一个或多个直接存取存储设备的访问。主计算机授权存储系统控制器在存储系统内的数据位置范围内搜索，设置数据搜索开始的初始位置，并指定要搜索的关键字段参数。然后，主计算机允许存储系统控制器独立地搜索存储系统内的数据位置的授权范围或存储系统控制器内的高速缓冲存储器内。存储系统控制器检查数据位置的授权范围内的多个记录，以定位与密钥字段参数相关联的期望记录，并且仅在找到所需记录或搜索整个数据范围之后才向主计算机呈现状态报告，没有找到所需的记录。只有在完成尝试在授权的记录范围内找到所需记录之后，才允许存储系统控制器独立地搜索记录和报告状态，从而最大限度地减少通信开销。通过通信渠道减少状态报告的数量增加了通信效率。

摘要： Embodiments of the disclosure relate to archiving data in a storage system. An exemplary embodiment comprises making a flash copy of data in a source volume, compressing data in the flash copy wherein each track of data is compressed into a set of data pages, and storing the compressed data pages in a target volume. Data extents for the target volume may be allocated from a pool of compressed data extents. After each stride worth of data is compressed and stored in the target volume, data may be destaged to avoid destage penalties. Data from the target volume may be decompressed from a flash copy of the target volume in a reverse process to restore each data track, when the archived data is needed. Data may be compressed and uncompressed using a Lempel-Ziv-Welch process.

摘要： A system and method for controlling peer-to-peer remote copy (PPRC) operations initiated from one or more host devices that desire to store data contents written to a first storage system to a second storage system over a communications link. The system enables receipt and generation of copy services commands from host devices and the determination of whether a received command pertains to a copy service over an established PPRC relationship for that particular customer to enable that customer to perform storage operations effecting data written to a first storage server having source volumes and stored in a remote second storage system having target volumes. The copy services command effecting data contents of source volumes and/or remote target volumes will be enabled if it is determined that said PPRC relationship is already established for that customer; and, prevented if the received copy services command does effect any volume not already in a copy services relationship.

摘要： An apparatus, system, and method are disclosed for copying data from a volatile memory device to a plurality of persistent storage devices in response to a loss of primary power. The apparatus includes a section module, a stripe module, and a write module. The section module sections a data image of a write cache into a plurality of data blocks. The stripe module establishes a plurality of data stripes from the plurality of data blocks. The write module writes in parallel each of the plurality of data stripes to a corresponding plurality of unique, persistent data storage devices in response to a loss of line power to the write cache. Advantageously, the apparatus quickly copies the write data from the write cache to a persistent memory device in a relatively short period of time, decreasing the dependence on significant batteries to back up the volatile memory device.
