This document details the equipment resident in the Holland Computing Center (HCC) as of October 2019.
HCC has two primary locations directly interconnected by a pair of 10 Gbps fiber optic links (20 Gbps total). The 1800 sq. ft. HCC machine room at the Peter Kiewit Institute (PKI) in Omaha can provide up to 500 kVA in UPS and genset protected power, and 160 ton cooling. A 2200 sq. ft. second machine room in the Schorr Center at the University of Nebraska-Lincoln (UNL) can currently provide up to 100 ton cooling with up to 400 kVA of power. One Brocade MLXe router and two Dell Z9264F-ON core switches in each location provide both high WAN bandwidth and Software Defined Networking (SDN) capability. The Schorr machine room connects to campus and Internet2/ESnet at 100 Gbps while the PKI machine room connects at 10 Gbps. HCC uses multiple data transfer nodes as well as a FIONA (flash IO network appliance) to facilitate end-to-end performance for data intensive workflows.
