MetaX 曦云C550 Shanghai Cube 液冷整机柜

MetaX's high-density liquid-cooled cabinet, and the largest single configuration it publishes. A 47U rack holds four 10U groups plus 7U reserved for switches, and each group is four 2U eight-OAM nodes and one 2U power shelf, giving 128 liquid-cooled 曦云C550 modules in one cabinet. Each 10U group forms a 32-card supernode, which MetaX describes as supporting flexible parallelism strategies for training and inference. MetaX claims the 128-card layout occupies 70 percent less floor area than comparable products, and that the GPUs, network switches and software stack are entirely domestic. No power, memory total or throughput figure is published for the cabinet.
