PowerBlock 50 Ultra-Compact Embedded Computing Chassis • Full-size chassis performance in 1/9 the volume of full ATR, 1/6 the volume of short ATR for SWaP-constrained applications • Six processing slots supporting up to 4,000 GFLOPS per system • State-of-the-art liquid, conduction, or convection cooling for up to 300W power • Designed for ruggedized deployments in harsh environments The PowerBlock® 50 Ultra-Compact Embedded Computing Chassis from Mercury Computer Systems is designed for systems delivering maximum performance in minimal size. It provides full ATR chassis performance in 1/9 the volume, deployable in even the most spaceconstrained aerospace/defense and commercial applications. The high-performance any-to-any PCI Express switch fabric delivers high-throughput, non-blocking, serial switching between processing and I/O nodes. External I/O can be customized to accommodate virtually any type of digital or analog I/O. Highly Configurable The PowerBlock 50 chassis is designed for rugged deployments, with features including o-ring sealing for pressure, humidity and EMI isolation, high-reliability connectors, extended temperature ranges, and module wedge locks for shock and vibration immunity. • High-performance computing modules featuring the latest FPGAs, designed to meet the most demanding application requirements for data processing and I/O • Single-board computing modules, coupled with dedicated I/O daughtercards, which monitor and manage the system and interface to external equipment over serial protocols and/or Ethernet The switched backplane provides four lanes of PCI Express® bandwidth to each of up to six plug-in modules, including: The PowerBlock 50 can be configured with a combination of modules supporting Intel® x86 processors, field-programmable gate arrays (FPGAs), and graphics processing units (GPUs). Fully loaded, it can deliver up to 4,000 GFLOPS of compute performance. The chassis is ultra-compact, measuring only 4.7” x 5.8” x 5.8” (120 mm x 149 mm x 148 mm). It is designed throughout to isolate its internal electronics from all external environmental and physical conditions, allowing deployments in harsh environments.
