Description
The FMC NVMe Expansion Daughter Card provides four NVMe interfaces (two on the top and two on the bottom of the board).
The SSD NVMe cards can be connected via the standard M.2 connectors. This board provides high bandwidth, low latency data storage capabilities that are too high memory requirements for bandwidth in applications such as High Performance Computing (HPC), High Frequency Trading (HFT), Machine Learning, Data Centers, and any application with fast R/W. All NVMe interfaces are connected to the Microsemi PM8532 PCIe switch. This chip provides a connection to the carrier card via the PCIe x8 GEN3 interface using a standard FMC connector. Microsemi PM8532 PCIe programmable switch enables four NVMe interfaces to be connected via PCIe x4 GEN3 and other FMC NVMe cards in a stack.
This daughter card supports the card stacking function with up to seven cards, ie up to 28 NVMe drives with an FMC connector on the carrier card. The FMC-NVMe daughter card is based on the Vita 57.1 standard and supported by Aldec TySOM™ embedded development boards and HES™ prototyping boards.
