摘要： A data de-duplication approach leverages acceleration hardware in SSDs for performing digest computations used in de-duplication operations and support on behalf of an attached host, thereby relieving the host from the computing burden of the digest computation in de-duplication (de-dupe) processing. De-dupe processing typically involve computation and comparison of message digests (MD) and/or hash functions. Such MD functions are often also employed for cryptographic operations such as encryption and authentication. Often, SSDs include onboard hardware accelerators for MD functions associated with security features of the SSDs. However, the hardware accelerators may also be invoked for computing a message digest result and returning the result to the host, effectively offloading the burden of MD computation from the host, similar to an external hardware accelerator, but without redirecting the data since the digest computation is performed on a data stream passing through the SSD for storage.
摘要翻译： 重复数据删除方法利用SSD中的加速硬件来执行重复数据删除操作中使用的摘要计算，代表附件主机进行支持，从而减轻了重复数据删除中的摘要计算的计算负担（de-dupe ）处理。 去重处理通常涉及消息摘要（MD）和/或散列函数的计算和比较。 这样的MD功能通常也用于加密操作，例如加密和认证。 通常，SSD包括用于与SSD的安全功能相关联的MD功能的板载硬件加速器。 然而，也可以调用硬件加速器来计算消息摘要结果并将结果返回到主机，类似于外部硬件加速器，从主机有效地卸载MD计算的负担，但是不需要重定向数据，因为摘要计算 在通过SSD进行存储的数据流上执行。

摘要： An optimized CD/DVD authoring method is disclosed. Either a pre-final version of a CD/DVD having a first block allocation or a disk image of the pre-final version of the CD/DVD with the first block allocation is first created. An alternate block allocation to the first block allocation that yields improved overall access time for the content of the CD/DVD is generated, if possible, based on the order a selected subset or the entire content of the CD/DVD is accessed. A final version of the CD/DVD is then generated using the alternate block allocation.

摘要： A method, apparatus and computer program for causing a host computer to optimize execution of plural requests for access to plural data storage locations on a rotating disk, included in a disk storage device, based on a rotational position of the disk relative to a position of a read/write head. The host computer stores position information representing a rotational position of the disk, detects whether plural requests are to be executed, and when plural requests are to be executed, optimizes execution of the requests by reordering a sequence of execution of the requests in a manner to reduce a total service time of the requests based on the position information.

摘要： Execution time performance of one or more applications that are dynamically loaded for execution post initial loading is improved by invoking selected parts of the one or more applications for execution post initial loading to allow disk locations accessed and the order the disk locations are accessed to load the selected parts of the one or more applications for execution post initial loading to be traced, and in turn, based at least in part on the order the disk locations are accessed, alternate disk locations to be identified to store the selected parts of the one or more applications to reduce time required to load the selected parts of the one or more applications for execution post initial loading.

摘要： An apparatus, as well as systems, methods, and articles can operate to record the address of write operations to a memory cached by a non-volatile cache prior to executing an operating system cache driver. In an embodiment, a non-volatile cache may be implemented by creating a device option read only memory (ROM), or modifying the associated computer basic input-output system (BIOS) to trap software interrupts associated with disk and other media access requests. Associated addresses, such as logical block addresses, can be stored in a log for data that is modified. The resulting log can be stored in a non-volatile medium, including the cache itself. If the available log space is not large enough to record all write activity prior to loading operating system drivers, a flag may be set to indicate the overrun condition.
