NATIVE-server-R1

The NATIVE-server-R1 is a compact MTCA chassis designed for server applications which comes with a NAT-MCH-G4 including an optional NAT-MCH-G4-CLK-P. Moreover, it comprises of a NAT-PM and an integrated NAT-AMC-COMex PrAMC (Processing AMC).

The chassis features four payload slots in total: two slots for double-wide, mid-size AMCs which can be expanded by two RTMs, and two slots for single-width, mid-size AMCs without RTMs.

Main Features NAT-MCH-G4

Basically, the NAT-MCH-G4 is the central management and data switching entity of the NATIVE-Server and handles power and system management.

The base Ethernet switch features a 1G / 2.5G / 10G Ethernet connection to the NAT-AMC-COMex module and all other AMCs in the system. Beyond that, a 1G-25G Ethernet uplink via SFP28-DD is available at the front panel.

In combination with the NAT-MCH-G4-CLK-P module, the NAT-MCH-G4 offers several options of switching and manipulating clock signals. Two low jitter Clock multiplexers provide CLK1 and CLK2 to each AMC. CLK3 is executed as PCIe Reference Clock.

The NAT-MCH-G4-CLK module features two SMA connectors at the front panel. Thereby, it feeds an external CLK signal to the MCH or extracts a CLK generated in the system. The direction of each SMA connector is configurable, the maximum frequency limit (as per MTCA.0 spec) is 100MHz.

As an assembly option, the NAT-MCH-G4-CLK module offers an optional GPS receiver with a dedicated SMC connector at the front panel to attach a GPS antenna.

Main Features NAT-AMC-COMex

The NAT-AMC-COMex is an COMExpress (COMex) carrier board for COMExpress Type7 modules. As the name implies, a COMExpress module is a Computer-on-Module, which means, it concentrates the core functionality of an x86 processing system on one single PCB. This includes CPU and memory functionality, graphics, and the most common interfaces.

For storage demands, the carrier owns an M.2 PCIe x4 interface, which offer various options to connect an SSD, FLASH memory, etc. A second M.2 PCIe x4 interface is intended to be used with a graphics module to provide an HDMI interface at the front plate.

Different types of COMExpress modules have been designed for different applications. Thus, the choice of the type determines the application field of the NAT-AMC-COMex. So the carrier board can work as a general purpose processor AMC (PrAMC), storage, or graphics solution if combined with the appropriate COMExpress module.

NAT has validated a number of COMExpress Type 7 modules suitable for installation on the NAT-AMC-COMex. Additionally, several CPU types are available. This variety of combinations offers a wide range of setups from well-priced to high-performing configurations.

Generally, the NAT-AMC-COMex features 25G Ethernet via SFP28 at the front panel and 10G Ethernet to AMC Port 0/1. Via FatPipe, it provides PCIe Gen4 x8 to the backplane.
