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.

The VT830 features dual Switching Shelf Managers (SSMs) that combines VadaTech’s 3rd Generation Shelf Manager with integrated GbE/10GbE/40GbE switches on the same module. This allows two slots in the system to be used as Nodes (Payload Boards) versus having the slots otherwise be allocated as dedicated switching Hubs in the system.

The 6U 6-slot SlotSaver ATCA Chassis conforms to the latest PICMG 3.0 specification in 10G or 40G configurations. The Shelf has a 19″ rackmount form factor compliant to EIA-310. The VT830 Shelf offers 10GbE/1GbE Layer 2 managed switches or 40GbE/10GbE/1GbE Layer 3 managed switches. The Switching Shelf Managers have RTM capabilities for rear I/O.

The AC input of the Shelf provides N+1 redundancy, with options for DC or AC/DC combined configurations. The 6U ATCA Shelf offers exceptional thermal management with each slot dissipating up to 375W in a redundant push/pull configuration. The fan trays and air filters are all separately removable.
