Appl. No.:

17/985402

Inventors:

International Classification:

G06F 13/26
G06F 13/42

Abstract:

Device virtualization techniques can enable physical I/O devices (such as PCIe devices or other I/O devices) to appear as virtual I/O devices, while also enabling selective exposure of information regarding the physical I/O devices to enable the native drivers of the physical I/O devices to be run. In one example, one or more physical I/O devices associated with a virtual I/O device are locked, and an interface is monitored for requests to those physical I/O devices. The device can be unlocked in response to a request to a predetermined address. When a physical I/O device is locked, read requests to read an identifier of the physical device are blocked, and a value associated with the virtual I/O device is provided. When the physical I/O device is unlocked, read requests to read an identifier of the physical I/O device are forwarded to the physical I/O device.

International Classification:

G06F 3/06

Abstract:

An embodiment of an electronic apparatus may include one or more substrates, and logic coupled to the one or more substrates, the logic to maintain a respective lookup table for each of two or more persistent storage devices in a persistent memory outside of the two or more persistent storage devices with a first indirection granularity that is smaller than a second indirection granularity of each of the two or more persistent storage devices, buffer write requests to the two or more persistent storage devices in the persistent memory in accordance with the respective lookup tables, and perform a sequential write from the persistent memory to a particular device of the two or more persistent storage devices when a portion of the buffer that corresponds to the particular device has an amount of data to write that corresponds to the second indirection granularity. Other embodiments are disclosed and claimed.

International Classification:

G06F 9/455
G06F 3/06
G06F 13/42

Abstract:

Techniques to facilitate an out-of-band (OOB) management in a virtualization environment include examples of assigning an endpoint identifier to a domain mapped to physical memory addresses of one or more storage devices coupled with a computing platform. The domain may enable software or a device driver executed by a virtual machine (VM) to access, manage or control at least a portion of the one or more storage devices. Examples also include receiving or forwarding messages through an OOB communication link coupled with the computing platform to a management entity to facilitate OOB management of the software or the device driver executed by the VM.

International Classification:

G06F 3/06
G06F 12/1009

Abstract:

A system including a storage drive and a semiconductor apparatus coupled to the storage drive, is provided. The semiconductor apparatus may include one or more substrates and logic coupled to the one or more substrates, the logic coupled to the one or more substrates to: initiate managing resources of the storage drive and, if the storage drive loses capacity, determine an amount of capacity loss, create a reserved file that is associated with logical memory space in a file system, based on the amount of the capacity loss, and erase at least a portion of the reserved file so that logical memory space associated with an un-erased portion of the reserved file is usable by the storage drive.

G06F 17/30

Abstract:

Systems and methods for issuing one or more write requests to a storage device, the system comprising one or more processors configured to generate one or more write requests, each write request comprising a respective data; tag each of the one or more write requests as a respective class from a plurality of classes, wherein the plurality of classes categorize data based on a rate at which it is written to the storage device; and issue the one or more write requests with their respective tags to the storage device, wherein the tag indicates to the storage device to write the first data proximate to data of the respective class within the storage device.
