UPDATE: Fall 2021: The new Dell PowerEdge R7525 server has arrived and is now online and operational. The new server has dual AMD 3.3/4.0 GHz 32-core 75F3 EPYC processors. This server is running in addition to our R920 servers and the data from the older MD3400 is being copied over to the newer, larger 160TB RAID storage volume on the server. It runs Ubuntu 20.04.3 LTS with the 5.11 kernel to better utilize the AMD EPYC architecture.
The seismology group also has a pair of two Dell PowerEdge R920 servers running CentOS Linux, sharing a total of over 60TB of networked disk space managed by a PowerVault MD3400 RAID controller. The servers both contain 24 cores each (one has quad 1.9GHz Xeon E7-4809 v2 6-core processors, the other has dual 2.6/3.2 GHz Xeon E7-4860 v2 12-core processors.) One R920 has 128GB of RAM and the other has 256GB. These Dell servers all have MATLAB and a large collection of geophysical software dedicated for the analysis of seismic data (Antelope, SAC, IRIS PASSCAL software, Bob Herrmann’s SLU software, Earthworm, TauP, ParaView, PyWeed, GMT).
In 2019 we acquired a 120TB Synology 12-bay network attached storage (NAS) system to better organize and archive our large repository of seismic data. Available to the clusters and the server farm, this archive will allow the attached storage on the computational systems to be more efficiently utilized.
These servers are primarily used by seismology students and researchers working with Doug Wiens and Michael Wysession. Interested students and researchers should contact Hugh Chou for further information on using the systems.
