Gigabyte TO16-A81 Server - System Overview

TO16-A81 nodeAdditional Information

With 12x memory channels per processor, using RDIMMs memory will run at up to 6400MT/s or up to 8000MT/s using MRDIMMs. MRDIMMs are only compatible on Intel Xeon 6 processors with P-cores. The Gigabyte TO16-A81-LA01 ORV3 Server is a high-density platform offering high core counts and power efficiency for AI and high-performance computing, cloud computing, and analytics, to name a few. Each node has 2x E3.S drive bays. Power for the system is provided by an OR3V rack with a 48V to 54V DC blind connect bus bar at the back of the rack. At 21-inches wide for OCP components, the rack also provides better air flow and is liquid-cooling ready. 

For expansion, the system has 3x low-profile PCIe Gen5 x16 slots. For management, the system has a front management LAN port that accesses the integrated ASPEED AST2600 baseboard management controller (BMC) microprocessor. DLC is provided via CPU cold plate loops.
