The VT878 is a conduction cooled chassis designed to accept two AMC modules with direct port-to-port connections.The modules are captive within the chassis, with close thermal coupling to the upper surface.

Depending on installation requirements, the lower surface of the unit can be bolted to a vehicle bulkhead or a cold plate for additional cooling.The chassis includes a DC input power provision that can be customized for particular vehicle platform requirements. No MCH provision is included, so the unit will boot autonomously.

Since the backplane and the internal sky lining of the chassis are specific to the AMC module pair integrated into the system, this unit is intended for volume applications.

The VT840 is a 1U μTCA chassis that provides six mid-size AMC slots with swappable redundant power in the rear of the chassis. The six slots are divided among two sets of three slots, each set with their own dedicated PCIe Fabric, GbE, Power Module, clock structure, and management. The fabric on ports 4-11 is PCIe (AMC.1) and ports 2-3 are routed to adjacent slots (AMC.3). Other features include FCLK to each AMC, a single digital input/output pin per unit (two total on the front panel), and front to rear cooling. The 300W AC power/fan trays and air filters are removable for ease of serviceability.

The VT840 runs management software based on VadaTech’s proven VT002 second generation mezzanine. The shelf manager implements IPMI management, FRU management, and shelf environment management for power, thermal, E-keying, etc. The VT840 has integrated dual 10GbE network interface, which connects to the PCIe fabric via x8 PCIe Gen3.

The VT835 offers unprecedented performance density with 1 ATCA node slot and 8 mid-size, single width AMCs in 3U height. Typically, only 4 mid-sized AMCs can fit on an ATCA carrier, with VadaTech’s unique design, 8 AMCs can fit in a single chassis to provide AMC’s versatility of processors, FPGAs, storage, graphics, I/O options and much more. Double-width AMCs can also be implemented.

The two slots support modules up to 400W, allowing the use of a high power host processor and AMC. Additional I/O is available through two standard ATCA RTMs. The VT835 has full redundancy support for all FRUs, including dual Shelf Managers.
