Data storage system

Storage system is built on Lustre file system and consists of three nodes with hard disks combined into RAID arrays. One node is a head node of the Lustre server (MDS) and the remaining two are actual storage nodes (OSS).



All the computing nodes are connected by the Infiniband 4x DDR network,
network card MHES18-XTC,
network commutator Mallanox MTS2400 InfiniBand HCA 24-Port HCA Switch.
This network is used for communication between parallel user tasks. The connection between computing nodes and Lustre file server is through Gigabit Ethernet.
