The Open Compute Project has been gaining influence throughout the server industry. Gigabyte released a RACKLUTION-OP line for 21″ open rack standards. Gigabyte adopted the OCP mezzanine card standard for their server platforms, even 19″ designs. Now Gigabyte is expanding its RACKLUTION-OP line with a series of Open Rack Standards Version 2.0 designs for its next-generation server products.


RACKLUTION-OP is the name for Gigabyte’s server product line based on the Open Compute Project’s 21” Open Rack Standards. The company has now released two versions of RACKLUTION-OP products. These correspond to Version 1.0 or Version 2.0 of the OCP Open Rack Standards. The most important change from Version 1.0 to Version 2.0 is the change from a triple bus-bar power distribution system (Version 1.0) to a single bus-bar system (Version 2.0). Both systems will continue to co-exist with each other, and customers can choose the design version based on their preference and requirements.

OCP is growing in popularity and we are seeing more companies offer innovative designs in this space.


  1. For the TO21-C20 think you might’ve accidentally written 4 x 3.5” instead of 4 x 2.5” if I am not mistaken? Had to go back and forth to the website to double check that.

    Hmm that 12OU Mini Rack is intriguing, not really across the OCP gear enough to be sure, but that might be of interest to the folks on the forums who’ve bought the early OCP designs for cheap… but want a proper mounting solution… assuming OU Mini Racks aren’t already a thing and that it’s not crazy expensive.
