Abstract: A storage system configured to mitigate the effect of a long latency tail in solid state drives. The system includes a host and a plurality of solid state drives. The host sets a latency threshold in each solid state drive. Each solid state drive may abort any read command when the execution time exceeds the latency threshold, and the host may then send the same read command to another solid state drive.

Abstract: A data replication system has a chassis including a plurality of eSSDs, a fabrics switch, and a baseboard management controller (BMC). The BMC configures one of the plurality of eSSDs as an active eSSD and one or more of the plurality of eSSDs as one or more passive eSSDs. The fabrics switch of the chassis is programmed to forward packets destined for the active eSSD to both the active eSSD and the one or more passive eSSDs. In response to a host data write command received from the host, the active eSSD stores the host data and sends an address and an instruction corresponding to the host data to the one or more passive eSSDs. Each of the one or more passive eSSDs stores a copy of the host data using the address and the instruction received from the active eSSD and the host data received in the packets forwarded by the fabrics switch.

Abstract: A data storage device includes: a data storage medium; a processor comprising a plurality of processor cores; a plurality of application acceleration black-box (AABB) slots including reconfigurable logic blocks, interconnects, and memories; a host interface that receives a host command from a remote application running on a remote host computer, wherein the host command includes an image file including a register-transfer level (RTL) bitstream and a firmware driver; and a configuration controller that downloads the RTL bitstream to an AABB slot of the plurality of AABB slots and reconfigure the AABB slot, and load the firmware driver to a processor core of the processor. The processor core loaded with the firmware driver runs a data acceleration process of the remote application to access and process data stored in the data storage medium using the RTL bitstream downloaded in the AABB slot.

Abstract: A local management console includes: a communication interface to connect to a baseboard management controller (BMC) of a chassis in a data storage rack; and a display that displays information associated with one or more data storage devices included in the chassis. The information includes at least one of configuration, control, debugging, or status data associated with at least one of the one or more storage devices. The local management console connects to the BMC through the communication interface, and responsive to receiving a first interaction associated with the display, performs at least one of a configuration, control, debugging, or status acquisition operation on at least one of the one or more data storage devices.
