2018 Supercomputer upgrade

At mid 2018, the shared storage system has been upgraded, adding a new high performance filesystem with 555 TB and a long term object storage with a raw capacity of 6 PB. This new upgrade increases the performance of the filesystem thanks to a super fast SSD layer of 55TB. Hot data is kept on the faster storage layer, being moved down to a second level of 500 TB NL-SAS disks when data is not used. The storage uses the infiniband network between all nodes of the system.
