 ## NVMe Over Fabrics File System
+
 Attach a volume from an NVMe storage and mount it as a file-system. File-system is mounted on /mnt/nvmeof (on the first node of the job).
 Barbora cluster provides two NVMeoF storage nodes equipped with NVMe disks. Each storage node contains seven 1.6TB NVMe disks and provides net aggregated capacity of 10.18TiB. Storage space is provided using the NVMe over Fabrics protocol; RDMA network i.e. Infiniband is used for data transfers.

 ## Smart Burst Buffer
+
 Accelerate SCRATCH storage using the Smart Burst Buffer (SBB) technology. A specific Burst Buffer process is launched and Burst Buffer resources (CPUs, memory, flash storage) are allocated on an SBB storage node for acceleration (I/O caching) of SCRATCH data operations. The SBB profile file /lscratch/$PBS_JOBID/sbb.sh is created on the first allocated node of job. For SCRATCH acceleration, the SBB profile file has to be sourced into the shell environment - provided environment variables have to be defined in the process environment.
 
 Barbora cluster provides two SBB storage nodes equipped with NVMe disks. Each storage node contains ten 3.2TB NVMe disks and provides net aggregated capacity of 29.1TiB. Acceleration uses RDMA network i.e. Infiniband is used for data transfers.
