Euler contains two types of storage system:
- An enterprise-class NAS system (NetApp FAS 9000 & AFF A800) for long-term storage, such as home directories, applications, virtual machines, project data, etc.
- A high-performance Lustre parallel file system (DDN ES14KX) for short- and medium-term storage, such as scratch and work file systems
Home directories and other critical data are backed up daily; all other data (except scratch) are backed up at least once per week for disaster recovery.
Euler contains multiple networks:
- A common 10 Gb/s Ethernet network for data transfer between the storage systems and the cluster's compute and login nodes
- Three separate 56 Gb/s InfiniBand FDR networks for data transfer between the compute nodes themselves (e.g. MPI)
- A 100 Gb/s InfiniBand EDR network for data transfer within Euler IV (MPI) and between Euler IV and the new Lustre high-performance storage system
- A 200/100 Gb/s InfiniBand HDR network for data transfer within Euler VI, with 100 Gb/s from compute nodes to switches and multiple 200 Gb/s links between switches
