Data Storage

Total data storage capacity – 4.8 PB

• 2,3 ПБ in a high-performance parallel Lustre filesystem
• 2,5 ПБ in a highly reliable Ceph storage

Lustre storage is built in a highly-reliable manner. Servers are joined in groups of two. Each group can withstand a loss of one server without losing access to the full storage capacity. Lustre is available via InfiniBand network.

Ceph storage is built with twenty 16-bay disk servers populated with 8 TB helium-filled SATA disk drives. Ceph servers are connected to InfiniBand network at 100 Gbps and to Ethernet network at 20 Gbps. Ceph is used as an attachable block storage for VMs and as a back-end for the NRC “Kurchatov institute” federated data storage system.
