Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include flash memory to store data and may support a plurality of device streams. A SSD controller may manage reading and writing data to the flash memory, and may store a submission queue and a chunk-to-stream mapper. A flash translation layer may include a receiver to receive a write command, an LBA mapper to map an LBA to a chunk identifier (ID), stream selection logic to select a stream ID based on the chunk ID, a stream ID adder to add the stream ID to the write command, a queuer to place the chunk ID in the submission queue, and background logic to update the chunk-to-stream mapper after the chunk ID is removed from the submission queue.

Abstract: A system and method of generating representative I/O. The system is configured to utilize representative I/O patterns stored in a pattern database. A user may select one or more patterns to perform I/O using. The patterns are modified according to user supplied parameters and multiple parameters are integrated into a single workload. I/O is then generated according to the workload and system performance may be measured.

CPC classification number: G06F13/102 , G06F9/44505
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: A Solid State Drive (SSD) is disclosed. The SSD may include flash memory to store data. An SSD controller may manage reading and writing data to the flash memory. The SSD may include an automatic stream detection logic to select a stream identifier responsive to attributes of data. A garbage collection logic may select an erase block and program valid data in the erase block into a second block responsive to a stream ID determined the automatic stream detection logic. The stream ID may be determined after the garbage collection logic has selected the erase block for garbage collection.

Abstract: A method may include receiving, at a storage device, a command using a storage protocol, wherein the storage device is configured to execute a user program, and executing, at the storage device, a device program based on the command. The command may be a first command, and the method may further include receiving, at the storage device, using the storage protocol, a second command, and sending, from the storage device, using the storage protocol, information about the device program based on the second command. The method may further include sending, from the storage device, using the storage protocol, a list of device programs supported by the storage device based on the second command. The method may further include providing, by the storage device, output data from the device program. The providing may include sending, from the storage device, using the storage protocol, a log message.
