The Penguin Tundra cluster platform is based on Open Compute Project rack-level infrastructure, and is designed to deliver the highest density and lowest total-cost-of-ownership for high performance technical computing clusters. The product line includes compute sled, storage sled and an Intel Xeon Phi processor-based motherboard. The Intel Xeon Phi processor, code-named Knights Landing, delivers optimized performance for highly parallel applications. Each accelerator sled can be implemented interchangeably for similar or distinct operations. The Open Compute Project-based design allows third-party motherboards to fit in a Tundra sled so any branded motherboards can take advantage of the efficient space utilization in OCP’s Open Rack standard. While the previous density was two nodes in a 1U configuration, restricted by the 19” EIA standard traditional server width, it now enables three nodes in a 1U via a 21” wide server. The platform supports liquid cooling water blocks that allow highly dense racks, air conditioning cost savings and risk minimization for power overloads.
