Mezzanine CPU Side Card • M.2 NVMe SSD • Front I/O

Available as a mezzanine add-on expansion board (aka side card) e.g. for the SC5-FESTIVAL CompactPCI® Serial CPU, the SCZ-NVM is equipped with two M.2 NVMe type SSD module sockets, as a rugged mass storage solution. In addition, frequently required I/O functions (RS-232, USB 3.0, DisplayPort) are provided via front panel connectors.

Both M.2 sockets are suitable for PCIe based modules (M-key) up to the 22110 format. The upper connector establishes a PCIe Gen3 link x4 and should be used with the the main NVMe SSD. The lower connector M.2 socket supports a PCIe Gen3 link x2, either for NVMe SSD backup storage, or special purpose modules such as the Intel® Optane™ SSD or the EKF M01-NVSRAM.
