OCP Power for Data Centres

Relec Electronics are pleased to announce the introduction of a range of rack mounted power solutions meeting the requirements set by the Open Compute project (OCP).  Our power-shelf solutions provide rectification, system management, and power distribution, while maintaining high reliability and offering flexibility for future expansion.

The Open Compute Project (OCP) was launched in 2011, with the aim to accelerate the development of hardware designs that enable greater data center efficiency and flexibility. Since then, the OCP has gained traction in the market, growing into an influential community focused on open data center hardware.

The OCP Rack and Power definitions went beyond rack dimensions. The specification unbundles the traditional server configuration, deploying servers, storage and power on separate trays within the rack, providing greater flexibility in configuring racks with required equipment.

The OCP specification supports 13.2 kW of IT equipment within the rack. This is accomplished through the use of two power shelves within the rack, each of which consists of three power supplies in an N + 1 configuration. Power shelves can also include “smart boxes” which archive data in the event of a failure for diagnostics.

Higher density shelves can now be deployed without compromising efficiency, even if the initial capacity of the rack is well below the design specification. The power supplies shpwn below have a maximally flat efficiency curve across the load range. The efficiency curves also highlight the differences between Platinum and Titanium power supplies.

Titanium power supplies provide efficiency improvements at certain points of the curve. The efficiency of Platinum power supplies may provide improvements at other points, such as light and full loading.

The products highlighted below are a small selection of the solutions we can offer here at Relec.  Our technical team are standing by to take your call and provide you with the optimum OCP power solution.
