Abstract: One embodiment facilitates flash storage management. During operation, the system receives a request to write data to a non-volatile memory. The system writes, in a buffer in association with a controller, the data to a next available portion of a current physical page in a page stripe, wherein the page stripe includes physical pages which each correspond to a sequentially ordered die of the non-volatile memory. The system provides power-loss protection to the current physical page and a second physical page which indicates parity information for the page stripe, thereby providing power-loss protection to an increased number of partially full page stripes.

Abstract: Embodiments described herein provide a system comprising a storage unit, a control module, a compression module, and a communication module. During operation, the storage unit can store a piece of data. The control module determines whether data stored in the storage unit has triggered a storage operation in a distributed storage system. The compression module then compresses the piece of data by encoding the piece of data using fewer bits than the bits of the piece of data. Subsequently, the communication module sends the compressed piece of data to a plurality of storage nodes in the distributed storage system for persistent storage.

Abstract: One embodiment described herein provides a data storage system. The storage system includes a communication interface for receiving a write command from a host of the data storage system and a first write cache coupled to the host via the communication interface. The write command includes to-be-written data and address information associated with the to-be-written data. The first write cache is configured to temporarily store the to-be-written data before sending the to-be-written data to a high-capacity storage device coupled to the host, and the first write cache is configured to update its content by performing byte-level in-place writing based on the received write command.

Abstract: One embodiment facilitates global data placement in a storage device. The system receives a request to write first data. The system selects one of a plurality of physical media of the storage device to which to directly write the first data, based on a frequency of access, a block size, and a latency requirement of the first data, wherein the plurality of physical media includes a fast cache medium, a solid state drive, and a hard disk drive. In response to determining that the frequency of access of the first data is greater than a predetermined threshold, or in response to determining that the block size associated with the first data is not greater than a predetermined size and determining that the first data is an update to existing data, the system selects the fast cache medium. The system writes the first data to the selected one physical medium.

The system receives, by a first server, a task assigned based on a global power state, wherein the first server includes one or more drives, a drive includes one or more channels, and a channel includes one or more integrated circuits. The system places an inactive drive into a power-saving mode. The system places an inactive channel of an active drive into the power-saving mode by using a power switch associated with each integrated circuit in the inactive channel. The system places an inactive integrated circuit of an active channel into the power-saving mode by using a power switch associated with the inactive integrated circuit. The system updates a data structure storing the global power state based on a current power state of the first server, the drives, the channels, and the integrated circuits.
