摘要： A system and method for optimizing a storage system to support short data object lifetimes and highly utilized storage space are provided. With the system and method, data objects are clustered based on when they are anticipated to be deleted. When an application stores data, the application provides an indicator of the expected lifetime of the data, which may be a retention value, a relative priority of the data object, or the like. Data objects having similar expected lifetimes are clustered together in common data structures so that clusters of objects may be deleted efficiently in a single operation. Expected lifetimes may be changed by applications automatically. The system automatically determines how to handle these changes in expected lifetime using one or more of copying the data object, reclassifying the container in which the data object is held, and ignoring the change in expected lifetime for a time to investigate further changes in expected lifetime of other data objects.
摘要翻译：提供一种用于优化存储系统以支持短数据对象寿命和高度利用的存储空间的系统和方法。使用系统和方法，数据对象将基于何时被预先删除而进行聚类。当应用程序存储数据时，应用程序提供数据的预期寿命的指示符，其可以是保留值，数据对象的相对优先级等。具有相似的预期寿命的数据对象在公共数据结构中聚集在一起，使得可以在单个操作中有效地删除对象簇。预期的使用寿命可能会自动更改。系统自动确定如何使用一个或多个复制数据对象来重新分类数据对象所在的容器，并忽略预期生命周期的变化，以调查预期生命周期的进一步变化，以期如何处理预期生命周期中的这些更改的其他数据对象。

摘要： A storage system includes a plurality of data vats, and a processor including an optimizing unit that optimizes a value of data stored in the storage system. The optimizing unit optimizes the value by computing and implementing an optimal decision for allocating new data to a first data vat of the plurality of data vats, moving existing data from at least a second data vat of the plurality of data vats to the first data vat, and deleting existing data from the first data vat, based on an amount of data in each of the plurality of data vats.

摘要： When an alarm condition relating to a performance goal of a storage system is detected, a storage management system invokes an N-step lookahead engine for simulating operation of the storage system when there are multiple actions that could be taken by the storage system for eliminating the alarm condition. The N-step lookahead engine generates N possible system states based on a current state of the storage system. The N possible states are based on a cost model of each of the multiple actions. Each cost model is based on an action, a behavior implication of the action, a resource implication of the action and a transient cost of the action. An action is selected that generates a system state that optimizes the stability, a prerequisite and a transient cost of invoking the selected action.

摘要： A method for reducing data loss and unavailability by integrating multiple levels of a storage hierarchy is provided. The method includes receiving a read request. In addition, the method includes recognizing a data failure in response to the read request. The method further includes locating an alternate source of the data to be read in response to recognizing the data failure. The alternate source includes data cached at devices in the storage hierarchy, data in a backup system, and cumulative changes to the data since the last backup. Moreover, the method includes responding to the read request with data from the alternate source.

摘要： A method and apparatus for compression and decompression of information, such as groups of computer program instructions, encodes (compresses) information comprising a plurality of units by receiving the information to be encoded, splitting the information into a plurality of subsets, each subset comprising a plurality of symbols, each symbol comprising at least a portion of a unit of information, and assigning a codeword to each symbol, for each subset. Preferably, the assignment is performed by determining the frequency of occurrence of each symbol, for each subset, and assigning a codeword to each symbol, based on the frequency of occurrence of each symbol, for each subset. In order to decode (decompress) encoded information, the information comprising a plurality of codewords, each codeword is decoded to form a symbol, each symbol is grouped into one of a plurality of subsets and the plurality of subsets is merged to form decoded information.

摘要： A method, apparatus, article of manufacture, and a memory structure for storing and retrieving data in physical sectors which are larger than the sector size presented to the user is disclosed. The method comprises the steps of receiving at least one user sector comprising write data, and writing the user sector to a portion of the physical sector of the storage device. In one embodiment, data is written to the data storage disk using existing data that was read from the storage disk for a RAID parity calculation.

A determination is made as to whether a second server owns the client locks. The first server issues a request to the second server to transfer ownership of the client locks to the first server, wherein the client lock requests are handled by the server owning the client locks.
