Abstract: A data storage system includes: a plurality of data storage devices; a motherboard containing a baseboard management controller (BMC); and a network switch configured to route network traffic to the plurality of data storage devices. The BMC is configured to identify a group of data storage devices among the plurality of data storage devices based on device-specific information received from the plurality of data storage devices and send identifiers of the group of data storage devices to a querying party.

Abstract: According to some example embodiments, a method for providing security to a storage device includes receiving, by the storage device, a public key via a network; sending, by the storage device, the received public key and a proposed configuration corresponding to the storage device to a security manager that resides in a control plane of the network; determining, by the security manager, whether the public key received from the storage device matches a private key available to the security manager; downloading, by the security manager, the proposed configuration to the storage device; determining, by the security manager, if the proposed configuration is successfully downloaded to the storage device; operating the storage device according to the downloaded configuration; and granting, by the security manager, a request to lease the storage device operating in the downloaded configuration for a time interval.

Abstract: A system is disclosed. The system may include a processor running an application program and a memory storing data being used by the application program. An upstream port enables communication with the processor; a downstream port enables communication with a storage device. The system may also include an acceleration module implemented using hardware and including an Acceleration Platform Manager (APM-F) to execute an acceleration instruction. The storage device may include an endpoint of the storage device for communicating with the acceleration module, a physical function (PF) to expose the storage device, a second function to expose the acceleration module, a controller to manage operations of the storage device, storage for application data for the application program, and a storage device Acceleration Platform Manager (APM-S) to assist the APM-F in executing the acceleration instruction. A downstream filter associated with the downstream port may intercept an acceleration instruction associated with a downstream Filter Address Range (FAR) received from the storage device and deliver the acceleration instruction to the APM-F, the acceleration instruction being. An upstream filter associated with the upstream port may intercept an acceleration instruction received from the processor and deliver the second acceleration instruction to the APM-F. The processor, the acceleration module, and the storage device may communicate via a Peripheral Component Interconnect Exchange (PCIe) bus. The acceleration module may support performing the acceleration instruction on the application data on the storage device for the application program without loading the application data into the memory.
