Summary of "ORV3 Meta Frame Specification"

Meta Open Rack Frame V3 (ORV3) Specification Overview

The video presents the Meta Open Rack Frame V3 (ORV3) specification, a collaborative development between Meta and ROL. It builds on the Open Rack V2 (ORV2) foundation and aligns with the Open Compute Project ecosystem.

Key Technological Concepts and Product Features

Rack Frame Design & Specification

ORV3 is a detailed implementation of Option One from the OR3 specification.
Provides essential structure and power to enable interoperability of open rack IT systems.
Dimensions:
- Height: 2,286 mm
- Width: 600 mm
- Depth: 1,198 mm
Supports 44 OU slots (an increase of 4 OU from ORV2) and 47 RU total.
Maximum payload: 400 kg (same as ORV2).
Rear door support rated for up to 150 kg.
Operating conditions:
- Temperature range: 10°C to 60°C
- Humidity: up to 85%

Power and Electrical

Supports 48V DC power.
Power shelf placement is flexible and can be located in any rack slot height-wise.

Mechanical Improvements

Fully toolless rack rails with snap-in latch features enable easier assembly and disassembly without screws.
Improved retention force for rails, meeting a minimum pull-out force of 400 newtons.
Cross brace is now a movable, assembled component (not welded), providing structural stiffening.
- Configurable between 18 OU to 27 OU or removable if load is below 800 kg.
Taller rack frame (76 mm taller than ORV2) to accommodate more equipment and improve airflow.

Cable Management

Modular, removable cable tray managers replace the fixed cable management of ORV2.
Customizable cutouts in cable trays allow flexible cable routing and easier access, even with doors installed.

Airflow and Cooling

Air flows front to rear.
New air containment blanks cover empty shelf spaces, improving airflow efficiency.
Containment components include:
- Top and bottom brackets
- Vertical strips
- Front strip
Future updates will cover blind mate liquid cooling support.

External Interfaces and Accessories

M8 threaded features for front/rear doors and cooling units.
M12 features for stabilizers and other accessories.
A stabilizer kit has been developed to support the taller rack and maintain stability, compliant with UL standards.

Testing and Robustness

Extensive dynamic and pull testing ensure durability and robustness during deployment and transport.
Design optimized for process capability and welding improvements.

Guides and Tutorials

Explanation of internal and external interfaces, including shelf kits (IT shelf and power shelf).
Demonstration of the toolless shelf kit installation and differences from ORV2.
Overview of cable management modularity and airflow enhancements.
Presentation of stabilizer kit and accessory mounting options.
Information on accessing full CAD files and specifications online.
Encouragement for community involvement in feature requests and future development via forums and email.

Q&A Highlights

Seismic and stability requirements are not standard but can be addressed on request.

Air containment blanks were chosen over simple blanking plates for cost-effectiveness and flexibility.

Airflow impact considerations were discussed regarding side coverage by air containment components.
