1. The four controllers of OceanStor 6800 V3 are located in one controller enclosure, and the nodes are fully interconnected through backplane PCIe channels.
2. The OceanStor 5300/5500/5600/5800 V3 four-controller cluster can use the 10GE direct connection solution or two HUAWEI CE6850 switches for interconnection. Cluster heartbeat and service data are transmitted through the same 10GE switching network.
3. In multi-controller mode, each controller must be configured with one 10GE SmartIO card, which must be fixed in the IOM1 (2 U) or IOM3 (3 U or 6 U).
