摘要： A method for efficiently using a large secondary cache is disclosed herein. In certain embodiments, such a method may include accumulating, in a secondary cache, a plurality of data tracks. These data tracks may include modified data and/or unmodified data. The method may determine if a subset of the plurality of data tracks makes up a full stride. In the event the subset makes up a full stride, the method may destage the subset from the secondary cache. By destaging full strides, the method reduces the number of disk operations that are required to destage data from the secondary cache. A corresponding computer program product and apparatus are also disclosed herein.
摘要翻译：本文公开了一种高效地使用大型二级高速缓存的方法。在某些实施例中，这种方法可以包括在二次高速缓存中累积多个数据轨道。这些数据轨道可以包括经修改的数据和/或未修改的数据。该方法可以确定多个数据轨道的一个子集是否构成一个完整的步幅。在子集构成一个完整的步骤的情况下，该方法可能会从二级缓存中退出该子集。通过降级整个步骤，该方法减少了从二级缓存中恢复数据所需的磁盘操作数。本文还公开了相应的计算机程序产品和装置。

摘要： A method for allocating space in a cache based on media I/O speed is disclosed herein. In certain embodiments, such a method may include storing, in a read cache, cache entries associated with faster-responding storage devices and cache entries associated with slower-responding storage devices. The method may further include implementing an eviction policy in the read cache. This eviction policy may include demoting, from the read cache, the cache entries of faster-responding storage devices faster than the cache entries of slower-responding storage devices, all other variables being equal. In certain embodiments, the eviction policy may further include demoting, from the read cache, cache entries having a lower read-hit ratio faster than cache entries having a higher read-hit ratio, all other variables being equal. A corresponding computer program product and apparatus are also disclosed and claimed herein.

摘要： A method to enable a user mode process to operate in a privileged execution mode is disclosed. Applicants' method provides an operating system comprising a privileged execution mode and a non-privileged execution mode, and a plurality of user mode strings operating in the non-privileged execution mode. The computing device receives a request from a first user mode string to operate in the privileged execution mode to perform one or more designated tasks. Applicants' method authorizes the first user mode string to operate in the privileged execution mode, and the first user mode string performs those one or more designated tasks using the privileged execution mode. Applicants' method continues to permit the first user mode string to operate in the privileged execution mode after completion of the one or more designated tasks.

摘要： Input/output (I/O) activity in the multiple tier storage system is monitored to collect statistical information. The statistical information is recurrently transformed into an exponential moving average (EMA) of the I/O activity having a predefined smoothing factor. Data portions in the multiple tier storage system are sorted into buckets of varying temperatures corresponding to the EMA. At least one data migration plan is recurrently generated for matching the sorted data portions to at least one of an available plurality of storage device classes. One data portion sorted into a higher temperature bucket is matched with a higher performance storage device class of the available plurality of storage device classes than another data portion sorted into a lower temperature bucket.

摘要： Provided are a method, system, and program for configuring shared devices over a fabric. A module in a first processing complex configures a first part of a fabric enabling communication with a set of devices accessible through the first part of the fabric. The module detects a located device accessible through a second part of the fabric, wherein a second processing complex is designated to configure the second part of the fabric and the located device. The module determines whether the second processing complex is available in response to detecting the uninitialized device. The module passes to a device driver in the first processing complex an uninitialized property for the located device. The device driver requests the module to configure the second part of the fabric to enable access to the located device over the second part of the fabric in response to determining that the located device has the uninitialized property.
