 The prototype consists of the main control blade, compute blade, switching backplane, heat dissipation system, power supply, and chassis.

1.1  main control blade

By the advantage of PCIe networking, we can unified the system-on-board (SoB) connection and the cloud cluster topologies into one single and simple architecture, which we named as Cloud-on-Board (CoB) Architecture.

In the CoB architecture, we can connect CPU directly without additional adapters.

FT - D2000 choose DDR4 particles as a memory / 8, 32 gb capacity, 3200 MTPS physical rate;

X100 choose DDR4 particles as memory, 8 gb capacity, 3200 MTPS physical rate;

FT - D2000 / between 8 and X100 use PCle Gen3X16 connection;

FT - D2000/8 by PCle Gen3X4 mount NVME hard disk, hard disk capacity of not less than 256 gb;

FT - D2000/8 WX1820AL via PCIE connection, providing two 10 g front-end ports;

Provide panel with DP, HDMI, USB3.1, Audio interface;Provide the necessary condition to the panel lights;

Reserved debug serial port debugging so;

1.2  compute blade

To provide back PCle Gen 3 by 8 signal, can be configured to RC and EP;

To provide back 1 gbe MDI network signal;

To provide back IPMI management based on 12 c interface;To provide panel 1 gbe network, USES the RJ45 interface;

To provide panel debug serial port, using the DB9 interface;

Provide panel with two USB 3.0 interface, using the Type - A interface;Provide panel with six software programmable control indicator light;

eFT - D2000/8 by PCle Gen3X4 mount NVME hard disk, hard disk capacity of not less than 256 gb;

Using DDR4 as a memory, not less than 32 gb capacity, interface physical rate not less than 3200 MTPS;

Through the network exchange chip 4 RK3588J FSL91030 connection module, access rate to 1 GBPS;

Each RK3588J module USES LPDDR4X memory, not less than 8 gb capacity, rate of not less than 4266 MTPS;

FT - D2000/8 through two PCle Gen3X4 and 2 PCle Gen3X1 four RK3588J and connectivity;

1.3 switching backplaner

Using FSL91030 in exchange for chips, two pieces of FSL91030 are redundant;

Each FSL91030 can provide up to eight 1 gbe port, each slot P2 side provide 2 road 1 gbe interface to be redundant FSL91030;

Each FSL91030 can provide up to two 10 gbe port, the P1 end of the slot number 3 and 4 provide 2 road 10 gbe interface to the FSL91030 are redundantBack to the slot provides IPMI management interface based on 12 c, located in each slot P0 end;

Back to the slot provides auxiliary power AUX + 5 v and + 12 v power supply, is located in each slot P0 end;

The backplane provides the engine fan power supply and control.
