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中的加速硬件执行重复数据消除操作中使用的摘要计算，并代表所连接的主机提供支持，从而减轻主机在重复数据删除中的摘要计算的负担（重复数据删除）处理。重复处理通常涉及消息摘要（MD）和/或散列函数的计算和比较。这种MD功能通常也用于加密操作，例如加密和认证。通常，固态硬盘包含板载硬件加速器，用于与SSD的安全功能相关的MD功能。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给主机，与外部硬件加速器类似地有效地减轻来自主机的MD计算的负担，但是自摘要计算以来没有重定向数据在通过SSD存储的数据流上执行。

摘要： Provided are a computer program product, system and method for determining adjustments to the spare space in a storage device unavailable to a user based on a current consumption profile of a storage device. A current write amplification is based on storage writes to a media at a storage device and host writes from a host to the storage device. An adjustment to the current write amplification is determined to produce an adjusted write amplification based on an estimated lifespan of the storage device, a maximum storage writes for the storage device, and the storage writes at the storage device since the storage device was powered-on. A determination is made to an adjustment to spare space based on the adjusted write amplification. The spare space and the free space available to the user are reconfigured to adjust the spare space by the determined adjustment to the spare space.

摘要： An SSD controller operates as an interface device conversant in a host protocol and a storage protocol supporting respective host and storage interfaces for providing a host with a view of an entire storage system. The host has visibility of the storage protocol that presents the storage system as a logical device, and accesses the storage device through the host protocol which is adapted for accessing high speed devices such as solid state drives (SSDs). The storage protocol supports a variety of possible dissimilar devices, allowing the host effective access to a combination of SSD and traditional storage as defined by the storage system. In this manner, a host protocol such as NVMe (Non-Volatile Memory Express), well suited to SSDs, permits efficient access to storage systems, such as a storage array, thus the entire storage system (array or network) is presented to an upstream host as an NVMe storage device.
摘要翻译： SSD控制器作为主机协议中的接口设备操作，以及支持相应主机和存储接口的存储协议，以向主机提供整个存储系统的视图。主机具有将存储系统呈现为逻辑设备的存储协议的可见性，并且通过适用于访问高速设备（例如固态驱动器（SSD））的主机协议访问存储设备。存储协议支持多种可能的不同设备，使主机可以有效地访问由存储系统定义的SSD和传统存储的组合。以这种方式，非常适合于SSD的诸如NVMe（非易失性存储器快速）的主机协议允许有效访问诸如存储阵列的存储系统，因此整个存储系统（阵列或网络）被呈现给上游主机作为NVMe存储设备。
