High-Density Servers

Dual CPUs Controller Module

The COTT 2U Dual-CPU High-Density Servers integrates the motherboard and PCIe add-on cards in a single controller module; forming an easily-swappable interface through high-speed signal connectors, and benefiting users from an administration and maintenance perspective.

Flexible Network and Storage Expansion 
Two types of controller with PCIE slot expansions and power supplies. The system can support a maximum of 4x full height PCIE slots with GPU cards with 2x internal 2.5″ integrated system drives,or up to 16x 3.5″ HDDs for the 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 motherboard supports up to 16 DDR4 memory DIMMs.
And the RDIMM maximum capacity supports 1TB of storage.

Cable-free Optimization
With a cable-free design, you can replace the cables by high-speed PCBs, greatly improving system reliability and heat dissipation performance.

Fully Modular Design
The controller, power supply, and hard disk are fully modular. If any part of the controller fails, just easily pull out the particular controller for maintenance.

BBU for Data Protection
During an accidental power down, the system will automatically enable the built-in backup battery to save the running data. It can prevent data loss and file system destruction, and sustain system operation for over  10 minutes.
