摘要： A method, system and program for generating parity in a data storage system are provided. The invention comprises organizing an incoming data block into a specified number of data stripes and cascading the data stripes into a parity creation mechanism. The parity creation mechanism creates a specified number of parity stripes based on the data stripes, wherein the number of parity stripes is independent of the size of the data block. The parity creation mechanism can operate offline to reconstruct lost data stripes and parity stripes without using critical system resources, wherein the number of devices required for stripe reconstruction is less than the combined number of data stripes and parity stripes.

摘要： Information that must remain secure is often stored on untrusted storage devices. To increase security, this information is encrypted by an encryption value prior to storing on the untrusted storage device. The encryption value itself is then encrypted. The encryption value is decrypted by correctly solving an access formula describing a function of groups. Each group includes a list of at least one consumer client. A requesting consumer client is granted access to the information if the requesting consumer client is a member of at least one group which correctly solves the access formula.
摘要翻译：必须保持安全的信息通常存储在不受信任的存储设备上。为了增加安全性，该信息在存储在不可信存储设备之前通过加密值进行加密。然后加密值本身被加密。通过正确解决描述组的功能的访问公式来解密加密值。每个组包括至少一个消费者客户端的列表。如果请求的消费者客户端是正确解决访问公式的至少一个组的成员，则请求消费者客户端被授予对该信息的访问。

摘要： A system and method for storing data in a storage system having storage elements arranged in parallel for concurrent access such that data can be continuously communicated to the storage element array while one of the storage elements is in error recovery. Some of the storage elements receive data of a stripe and the remaining storage elements receive parity information based on the data of the stripe. An unresponsive storage element in error recovery is dropped from the other storage elements for receiving data until error recovery is complete and the storage element is responsive for receiving data. While the storage element is unresponsive, one of the storage elements scheduled to receive parity information receives data to be written to the unresponsive storage element instead of the parity information. Communication to the storage elements continues while the failed storage element is in error recovery. Error recovery is accomplished by using the parity information of the other parity information storage elements.
摘要翻译：一种存储数据的系统和方法，所述存储系统具有并行排列的用于并发访问的存储元件，使得当所述存储元件中的一个处于错误恢复期间时可以将数据连续传送到所述存储元件阵列。一些存储元件接收条带的数据，并且剩余的存储元件基于条带的数据接收奇偶校验信息。错误恢复中的无响应存储元件从其他存储元件中丢弃，用于接收数据，直到错误恢复完成，并且存储元件响应于接收数据。当存储元件不响应时，调度为接收奇偶校验信息的存储元件之一接收待写入到无响应存储元件的数据而不是奇偶校验信息。与存储元件的通信继续，而故障存储元件处于错误恢复状态。通过使用其他奇偶校验信息存储元件的奇偶校验信息来实现错误恢复。
