MetaXLink card-to-card links in groups of two or four; two 400G adapters and two 25GE for networking
MetaX's PCIe server for the 曦云C500. MetaX lists the chassis as taking either 8 or 16 C500 boards, and the count shown here is the eight-card configuration. Alongside them sit mainstream domestic or international CPUs, 1 TB of DDR5 host memory, two 7.68 TB NVMe drives and two 480 GB SATA SSDs, with two 400G adapters and two 25GE for networking. Unlike the OAM-based C550 machine, MetaXLink here joins cards only in pairs or fours rather than one eight-card domain, which follows from the C500 being a standard full-height full-length PCIe board. MetaX publishes no system power, no accelerator memory total and no throughput.
