The TaiShan 2280 V2 uses two Huawei-developed Kunpeng 920 processors, each
supporting 16 DDR4 DIMMs.
The CPUs interconnect with each other through two Hydra buses at a speed of up to 30
GT/s.
The Ethernet FlexIOs can be cards with four GE ports, and are connected to CPUs
through high-speed SerDes interfaces.
The screw-in RAID controller card connects to CPU 1 through PCIe buses, and to the
drive backplanes through SAS signal cables. The drive backplanes support various local
storage configurations.
The iBMC is based on the Huawei Hi1710 management chip and provides a VGA port,
management network port, and debugging serial port.
