The Vera Rubin Observatory Computer Infrastructure is formed by four sites: La Serena, Cerro Pachon, Tucson and Cloud, each composed of several server’s clusters. This document details each Cluster’s amount of Nodes, Processing Capacity (CPU), Network Interfaces Information and Memory (RAM) Infrastructure per site. The Physical Storage information from each cluster will be devided into three:
System Storage: Represents the Disk Storage capacity that the OS has control of - /, /etc, /usr, /lib, /home, /var, /root, /opt-.
Data Storage: Disk unit space dedicated for data storage or common pool contribution.
Docker Storage: Storage Unit dedicated for running docker images - /var/lib/docker/-.
Usable Kubernetes Storage: All Rubin Clusters are provisioned with rook-ceph. Rook orchestrates ceph storage between the distributed nodes, allowing self-managing, self-scaling, and self healing storage services. The Usable Kubernetes Storage is then the total amount of usable space for the PV’s (over kubernetes).
