摘要： In one embodiment, a computer system includes a cache having one or more memories and a metadata service. The metadata service is able to receive requests for data stored in the cache from a first client and from a second client. The metadata service is further able to determine whether the performance of the cache would be improved by relocating the data stored in the cache. The metadata service is further operable to relocate the data stored in the cache when such relocation would improve the performance of the cache.

摘要： A method for assigning data in a plurality of physical storage resources for an information handling system is disclosed. The plurality of physical storage resources includes a first tier and a second tier with a lower performance and cost relative to capacity than the first tier. A tier manager hosted on the information handling system and in electronic communication with the plurality of physical storage resources is configured to: determine a seek distance value, operation rate, operation size value, and elapsed time value for each page; and calculate a relative randomness value for each page using the seek distance value, operation rate, operation size value, and elapsed time value determined for each page. A classification module may assign a physical location for each page such that the relative randomness value for each page in the first tier is greater than the relative randomness value for each page in the second tier.

摘要： A system and method for replacing cached data for a computer system utilizing one or more storage devices is disclosed. The storage devices are divided into a plurality of areas or bins. Each bin is preferably the same size. A Window Access Table (WAT) is an array stored in memory that contains all the time windows for each bin. Each time window holds a frequency value corresponding to the number of times the bin has been accessed during the time period corresponding to that time window. A hot spot algorithm is used to calculate a hot spot value hsf(x) for each bin based on its associated frequency values listed in the WAT. The hot spot algorithm uses scaling coefficients to weight the frequency values based on the time window. Each line in cache will therefore have an associated bin for which a hot spot value hsf(x) has been calculated. This data may be stored in a hot spot table. When data is retrieved from a storage in response to a cache miss, the memory controller will compare the hot spot value hsf(a) of the bin associated with the new data to the lowest hot spot value hsf(z) in the hot spot table. If hsf(z) is greater than hsf(a), then this indicates that bin (z), the bin with the lowest hot spot value is accessed more frequently than bin (a), the bin containing the retrieved data. Thus if hsf(z) is greater than hsf(a), then the cache line containing data from bin (z) will not be replaced. If hsf(a) is greater than hsf(z) then the new data from bin (a) will replace the cached data from bin (z).
摘要翻译：公开了一种用于替代利用一个或多个存储设备的计算机系统的缓存数据的系统和方法。存储装置被分成多个区域或仓。每个箱体最好是相同的尺寸。窗口访问表（WAT）是存储在内存中的数组，包含每个bin的所有时间窗口。每个时间窗口保持与在该时间窗口对应的时间段期间访问该仓的次数对应的频率值。热点算法用于根据WAT中列出的相关频率值计算每个仓的热点值hsf（x）。热点算法使用缩放系数根据时间窗对频率值进行加权。因此，高速缓存中的每一行将具有已经计算出热点值hsf（x）的关联仓。该数据可以存储在热点表中。当响应于高速缓存未命中从存储器检索数据时，存储器控制器将与新数据相关联的仓的热点值hsf（a）与热点表中的最低热点值hsf（z）进行比较。如果hsf（z）大于hsf（a），则表示bin（z），具有最低热点值的bin比bin（a）更频繁地访问，该bin包含检索到的数据。因此，如果hsf（z）大于hsf（a），那么包含bin（z）数据的缓存行将不会被替换。如果hsf（a）大于hsf（z），则bin（a）中的新数据将替换bin（z）中的缓存数据。

摘要： Systems and methods for managing cache configurations are disclosed. In accordance with a method, a system management control module may receive access rights of a host to a logical storage unit and may also receive a desired caching policy for caching data associated with the logical storage unit and the host. The system management control module may determine an allowable caching policy indicator for the logical storage unit. The allowable caching policy indicator may indicate whether caching is permitted for data associated with input/output operations between the host and the logical storage unit. The system management control module may further set a caching policy for data associated with input/output operations between the host and the logical storage unit, based on at least one of the desired caching policy and the allowable caching policy indicator. The system management control module may also communicate the caching policy to the host.

摘要： A system and method for providing automatic data restoration after a storage device failure are disclosed. An agent module detects a failure at a logical unit located at a primary storage device. The agent module locates backup data from the failed logical unit that is stored on a backup storage device and transfers the backup data from the backup storage device to a spare logical unit located on the primary storage device. The agent module then maps the spare logical unit to an address associated with a host in response to detecting the failure at the logical unit.
