摘要： The present disclosure is directed to a system for dynamically adaptive caching. The system includes a storage device having a physical capacity for storing data received from a host. The system may also include a control module for receiving data from the host and compressing the data to a compressed data size. Alternatively, the data may also be compressed by the storage device. The control module may be configured for determining an amount of available space on the storage device and also determining a reclaimed space, the reclaimed space being according to a difference between the size of the data received from the host and the compressed data size. The system may also include an interface module for presenting a logical capacity to the host. The logical capacity has a variable size and may include at least a portion of the reclaimed space.

摘要： The present invention is directed to a method for providing storage acceleration in a data storage system. In the data storage system described herein, multiple independent controllers may be utilized, such that a first storage controller may be connected to a first storage tier (ex.—a fast tier) which includes a solid-state drive, while a second storage controller may be connected to a second storage tier (ex.—a slower tier) which includes a hard disk drive. The accelerator functionality may be split between the host of the system and the first storage controller of the system (ex.—some of the accelerator functionality may be offloaded to the first storage controller) for promoting improved storage acceleration performance within the system.

摘要： A RAID system is provided in which, in the event that a rebuild is to be performed for one of the PDs, a filter driver of the operating system of the computer of the RAID system informs the RAID controller of the RAID system of addresses in the virtual memory that are unused. Unused virtual memory addresses are those which have never been written by the OS as well as those which have been written by the OS and subsequently freed by the OS. The RAID controller translates the unused virtual memory addresses into unused physical addresses. The RAID controller then reconstructs data and parity only for the unused physical addresses in the PD for which the rebuild is being performed. This reduces the amount of data and parity that are rebuilt during a rebuild process and reduces the amount of time that is required to perform the rebuild process. In addition, the RAID system is capable of being configured to prevent or reduce data sprawl.
摘要翻译：提供了一种RAID系统，其中，如果要对其中一个PD执行重建，则RAID系统的计算机的操作系统的过滤器驱动程序向RAID系统通知RAID系统的地址在未使用的虚拟内存未使用的虚拟内存地址是那些从未被操作系统写过的虚拟内存地址以及由操作系统编写的随后的操作系统。 RAID控制器将未使用的虚拟内存地址转换为未使用的物理地址。然后，RAID控制器将重新构建正在执行重建的PD中未使用的物理地址的数据和奇偶校验。这减少了在重建过程中重建的数据量和奇偶校验值，并减少了执行重建过程所需的时间。此外，RAID系统能够被配置为防止或减少数据蔓延。
