SMART’s DDR4 NVDIMM features proprietary SafeStor engine which employs multi-channel NAND Flash and high-speed switching circuitry to provide robust backup and restore capability, all while functioning as a JEDEC standard DDR4 RDIMM during normal operation.
NVDIMMs are used for accelerating computing performance for the embedded storage platforms, such as enterprise storage, HPC, and machine learning. With SMART's SafeStor Technology, data that DRAM is processing will be moved to NAND Flash using supercaps for backup power during an unexpected power loss event. Once the power is returned, DRAM data is restored from NAND Flash, and supercaps are recharged in minutes.
How Does It Work?
SMART’s SafeStor supports the engine which initiates backup and restore operations upon command from the host controller as well as manages the NAND Flash interface. The SafeStor engine employs multi-channel fast NAND and high-speed switching circuitry to provide robust backup and restore capability, all while functioning as a JEDEC standard DDR4 RDIMM during normal operation. Temporary power is provided to the NVDIMM during a sudden power loss (SPL) event by a hybrid supercap module, which can be tailored to individual application environments. SMART's expanded lineup of NVDIMMs features end-to-end error checking and correction capabilities to ensure a high level of data integrity during backup and restore operations.
