摘要： Systems and methods for dynamically placing data in a hybrid memory structure are provided. A machine learning (ML)-based, adaptive tiered memory system can actively monitor application memory to dynamically place the right data in the right memory tier at the right time. The memory system can use reinforcement learning to perform dynamic tier placement of memory pages.

摘要： Techniques and systems are described for enabling local independent failure domains in a host server or datacenter environment. Included is a locally-attached independent failure device (LA-IFD) with an independent data buffer and a local communications bus for attaching to a host server. Techniques for a communications protocol between the LA-IFD and its host server are provided, including: receiving a request to write a data segment to persistent storage; synchronously storing the data segment in a buffered data segment at the LA-IFD and initiating an asynchronous update of the data segment at a remote storage system; sending a write acknowledgement indicating completion to the requestor; and, after receiving a completion notification from the remote storage system, removing the buffered data segment from the LA-IFD. In some cases, techniques allow a host server and LA-IFD pair to monitor one another for failures and implement a modified protocol in the event of unavailability.

摘要： Techniques and systems are disclosed for implementing non-blocking writes to eliminate the fetch-before-write requirement by creating an in-memory patch for the updated page and unblocking the calling process. Non-blocking writes eliminate such blocking by buffering the written data elsewhere in memory and unblocking the writing process immediately. Subsequent reads to the updated page locations are also made non-blocking and, in some cases, can be eliminated when the read request can be serviced from in-memory patches.Implementation scenarios can include an operating system (OS) enhancement, revision to an existing OS component (e.g., the OS kernel), special OS component, or enhancement to the software or firmware of the controller software or microcontroller of a storage device or array of storage devices.

摘要翻译：公开了技术和系统，用于实现非阻塞写入，以通过为更新的页面创建内存中补丁并解除调用进程来消除写入前提取需求。非阻塞写入通过将写入的数据缓冲在存储器中的其他位置并立即解除写入过程来消除这种阻塞。对更新的页面位置的后续读取也被做成非阻塞，并且在一些情况下，当可以从内存中的修补程序中服务读取请求时，可以消除对更新的页面位置的后续读取。实施场景可以包括操作系统（OS）增强，对现有OS组件（例如，OS内核）的修订，特殊OS组件或对存储设备或阵列的控制器软件或微控制器的软件或固件的增强存储设备。
