HCC has two primary locations directly interconnected by a 100 Gbps primary link with a 10 Gbps backup. 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. Dell S4248FB-ON edge switches and Z9264F-ON core switches provide high WAN bandwidth and Software Defined Networking (SDN) capability for both locations. The Schorr and PKI machine rooms both have 100 Gbps paths to the University of Nebraska, Internet2, and ESnet as well as a 100 Gbps geographically diverse backup path. 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.

Attic and Silo form a near line archive with 3PB of usable storage. Attic is located at PKI in Omaha, while Silo acts as an online backup located in Lincoln. Both Attic and Silo are connected with 10 Gbps network connections.
NRDStor is a general purpose storage for use by researchers on their laptops, workstations, and labs. The storage capacity of NRDStor is approximatly 5PB.
In addition to the cluster specific Lustre storage, a shared storage space known as Common exists between all HCC resources with 1.9PB capacity.
