Dual CPUs Controller Module

The COTT® Dual-Controller Server barebone integrates the mainboard and PCIe add-on cards in one controller module. and forms an easy-swappable structure with the backplane through high-speed signal connectors, which benefits users from administration and maintenance perspective.


High Performance

One dual processor node is deployed in a standard 2U form factor space, supporting two Intel® Xeon® E5-2600 v3/v4 series processors in spread-core layout, and a built-in high-speed M.2 PCIe SSD. The overall performance is several times higher than most of traditional 4U rack servers. It is suitable for large-scale network application environments with high space and performance requirements, such as virtual desktops, large-scale graphics rendering, and cloud platforms.

Flexible Network and Storage Expansion 

Two type of controllers fulfills different rear drives density,PCIe slot expansions and power supplies. The system maixmun support 4x full height PCIe slot with GPU cards with 2x internal 2.5″ system drives integrated,or up to 12x 3.5″ HDDS for highest storage density with two full height PCIe slots. Each controller type can support up to 4x GbE ports or 2x 10GbE  ports as options.


Massive Memory 

The mainboard supports up to 16 DDR4 memory DIMMs.

And the RDIMM maximum capacity supports 1TB.

Cable-less Optimization

The entire system realizes a cable-less design in mechanism. Replace the cables by high-speed PCBs, which greatly improves the system’s reliability and heat dissipation performance. At the same time, it avoids the aging and loosening connection caused by cables.

Fully Modular Design

The controller, power supply, and hard disk are fully modularized. Once any part of the controller fails, just easily to pull out the controller for maintenance.

BBU for Data Protection

In an accident of power down, the system will automatically enable the built-in backup battery to save the running data. It can prevents data loss and file system destruction, and the sustainable system operation exceeds 10 minutes.
