Abstract: A storage device (220) is described. The storage device (220) may store data in a storage memory (445), and may have a host interface (420) to manage communications between the storage device (220) and a host machine (110, 115, 120, 125, 130). The storage device (220) may also include a translation layer (430) to translate addresses between the host machine (110, 115, 120, 125, 130) and the storage memory (445), and a storage interface (440) to access data from the storage memory (445). An in-storage monitoring engine (425) may determine characteristics (605, 610, 615) of the storage device (220), such as latency (605), bandwidth (610), and retention (615).

Abstract: A method for communicating with a device may include running, at a device, an operating system, communicating, using a first function of an interconnect, with the device, and communicating, using a second function of the interconnect, with the operating system. The operating system may include communication logic, and the communicating with the operating may include communicating with the communication logic. The communication logic may one or more terminal support drivers, and the communicating with the communication logic may include communicating with the one or more terminal support drivers using a terminal application. The terminal application may run on a host. The second function of the interconnect may be configured to operate with a controller. The communicating with the operating system may include communicating with the operating system based on a privilege information. The host may be a management controller. The method may further include controlling, using the second function of the interconnect, a program on the operating system.

Abstract: Systems and methods for memory management are described. An example method can include: performing a first determination that may include: comparing a first parameter associated with a storage device to a second parameter associated with an application. In addition, the method may include performing a second determination based on the first determination, where the second determination may include: inserting data into a storage partition of the storage device; and determining to store a minimum processing unit associated with the data in the storage device.

Abstract: A method for transferring data may include writing, from a producing device, data to a storage device through an interconnect, determining a consumer device for the data, prefetching the data from the storage device, and transferring, based on the determining, the data to the consumer device through the interconnect. The method may further comprise receiving, at a prefetcher for the storage device, an indication of a relationship between the producing device and the consumer device, and determining the consumer device based on the indication. The method may further comprise placing the data in a stream at the storage device based on the relationship between the producing device and the consumer device. The indication may be provided by an application associated with the consumer device. Receiving the indication may include receiving the indication through a coherent memory protocol for the interconnect.
