Ensemble® 6000 Series LDS6527 OpenVPX Intel Xeon D server-class module with I/O mezzanine sites

Product Description

The Ensemble 6000® Series LDS6527 6U OpenVPXTM is a single board computer (SBC) with options for Modified Off the Shelf (MOTS) extreme durability configurations and BuiltSECURE™ technology. MOTS configurations leverage enhanced commercial components, board fabrication rules, and subsystem design techniques for extra ruggedness and withstand extreme temperature cycles better than other rugged designs.

For deployment at the tactical edge and export to allies, the Ensemble LDS6527 embeds BuiltSECURE technology to counter nation-state reverse engineering with security engineering (SSE). BuiltSECURE is built-in SSE that enables turn-key or private and personalized security solutions to be quickly configured. The extensible nature of Mercury's SSE delivers system-wide security that evolves over time, building in future-proofing. As countermeasures are developed to offset emerging threats, Mercury's security framework keeps pace, maintaining system-wide integrity. Please contact Mercury directly for BuiltSAFE and extra rugged MOTS options.

Ensemble LDS6527 SBCs combine a powerful, 12-core server-class Xeon D processor, Mellanox CX-3 bridged Ethernet or InfiniBand high bandwidth switching, and configurable mezzanine I/O. Each SBC has a next-gen architecture that blends the computational power of an AVX2-enabled Xeon D processor with fast InfiniBand or 40Gb/s Ethernet data paths and the versatility of mezzanine-mounted I/O. This scalable computing architecture is well aligned to EW, next-gen radar, complex IMINT, multi-functional sensor chain and advanced situational awareness applications.
