1. System Architecture

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

1.1  main control blade

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

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

CPU between 8 and SOC use PCle Gen3X16 connection;

CPU by PCle Gen3X4 mount NVME hard disk, hard disk capacity of not less than 256 gb;

NETSOC 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;

CPU 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 soc and XPU connection module, access rate to 1 GBPS;

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

CPU through two PCle Gen3X4 and 2 PCle Gen3X1 four SOC and connectivity;

1.3 switching backplaner

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

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

Each XPU 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 XPU 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.

2. Hardware Design

3.1 Cloud-on-Board (CoB) Architecture

For general computing, we introduce the CoB with three major components:

1) Edge Computing Module (ECM): CPU+RAM+OS SSD combo,

2) Edge Base Board (EB2): for PCIe Data Fabric,

3) Edge Adapter Module (EAM): PCIe-compatible Device, such as GPU, NIC, SSD etc.
