Infrastructure nodes
- 2 management nodes
- 2 lustre OSS
- 2 lustre MDS
- dual socket, quad core (Intel Xeon E5345, 2.33 GHz)
- pairwise failover
Storage
- NexSAN SATAbeast
- 30 TB raw RAID-5, 22 TB effective
- Lustre parallel file system
- 160 GB local disk per compute node
- 2 × 250 GB local disk in frontend nodes, as RAID1
- NFS
- highly-available server based on DRBD
- used for cluster management
Interconnect
- Infiniband 4x DDR (Mellanox, onboard ) – MPI and Lustre
- Ethernet 1 GB/s – node access and management
- Ethernet 10 Gb/s – crosslinks and uplink
- FibreChannel – storage backends
Power
- UPS (2) – carries infrastructure nodes and network switches
- PDUs – switched and metered
- Power consumption
- peak: 89 kW
- full load (average): 55 kW
