HCC has two primary locations directly interconnected by a set of four 10 Gbps fiber optic links (40 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. Brocade MLXe border routers, one 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's resources at UNL include two distinct offerings: Sandhills and Red. Sandhills is a linux cluster dedicated to general campus usage with 5,024 compute cores interconnected by low-latency InfiniBand networking. 175 TB of Lustre storage is complemented by 50 TB of NFS storage and 3 TB of local scratch per node.
The largest machine on the Lincoln campus is Red, with 9,536 job slots interconnected by a mixture of 1, 10, and 40 Gbps ethernet. More importantly, Red serves up over 6.6 PB of storage using the Hadoop Distributed File System (HDFS). Red is integrated with the Open Science Grid (OSG), and serves as a major site for storage and analysis in the international high energy physics project known as CMS (Compact Muon Solenoid).
Anvil is an OpenStack cloud environment consisting of 1,520 cores and 400TB of CEPH storage all connected by 10 Gbps networking. The Anvil cloud exists to address needs of NU researchers that cannot be served by traditional scheduler-based HPC environments such as GUI applications, Windows based software, test environments, and persistent services.
