Data transmission network

Communication network: Infiniband 4x QDR and DDR with a capacity of 40 and 20 Gbit/s, respectively, and latency of about 1-7 µs. It is designed for access to networked storage systems and for the interaction of parallel processes running on different servers of the cluster.

Transport network: Gigabit Ethernet, used to manage server operating systems and running processes.

Storage Systems

RAID 1 and 5 RAID arrays are used to provide fault tolerance.

The cluster file system Lusterre FS 64T is used to store data.
