GIGABYTE OCP ORV3 Compliant Solutions
GIGABTYE is an active member of the OCP, regularly attending the OCP's annual summits and continuously designing and releasing
new compute, storage and GPU server hardware based on the OCP Open Rack Standard specifications and providing the best
performing mezzanine cards for your OCP solution. GIGABYTE’s latest OCP server product line is based on OCP Open Rack V3
specification. The products are designed for a 21" OCP rack and feature a separate PSU system, with power supplied to each server
node by a bus-bar system running along the rear of the rack.

GIGABYTE OCP ORV3 Compliant Solutions Advantages
Efficient Rack Density• Optimal design (2OU 2nodes / 2OU 3nodes) - balanced consideration between density andpower consumption.

Thermal Optimization• Best thermal consideration to develop Rack and Nodes based on Cold Aisle/Hot Aisle concept.
• Reduce power consumption of cooling.

Greater Power Efficiency• Low PUE helps reduce data center operating expense.
• Central power shelf design to enhance power efficiency and optimize power consumption.

Easy Maintenance• Easier maintenance in front cold aisle instead of hot aisle.
• Tool-less design for easy replacement and repair.
• Less PSU quantities in whole rack to minimize maintenance efforts.

Higher MTBF
• Centralizing power supplies and removing unnecessary components to enhance MTBF
(Mean Time Between Failures).
• Avoids system downtime caused by component failure and minimizes maintenance efforts.

The Future of Open Source Ecosystem
The Open Compute Project (OCP) is a collaborative community focused on redesigning hardware technology
to efficiently support the growing demands on compute infrastructure. In 2011, the OCP Foundation wasinitiated with a mission to apply the benefits of open source and open collaboration to hardware and rapidly
increase the pace of innovation. Its collaboration model is now being widely applied in fields like data centers,telecom industry, and edge infrastructure.

Flexible Node Configuration
GIGABYTE’s OCP Open Rack Version 3 compliant solutions maintain the cost-efficientdesigns created in version 2, yet these new solutions provide even more power to eachnode. GIGABYTE TO23-BT0, a 2OU node tray, supports three nodes and up to six CPUs
in a single tray. And a similar node tray, TO25-BT0, is designed for more PCIe expansion
slots with each tray supporting up to four dual-slot GPUs or eight full-height full-length
single slot cards for growing HPC and AI needs in data centers.
