 Storage

All nodes have access to common storage :

  • common storage : /home
    • 31 TiB, available to all users, quotas per user
    • 1 Dell PowerEdge R540 server with 2 RAID-10 array 10 x 10TB SAS 7.2 kRPM disks, infiniband FDR, NFS access
  • capacity distributed and scalable common storage : /data
    • ~610TiB real capacity, 684TB theoretical capacity (06/2019)
      • permanent storage : 1TiB quota per team + teams may buy additional quota (please contact cluster administrators)
      • scratch storage : variable size (initially ~40TiB), no quota limit, for temporary storage (data may be purged)
    • BeeGFS filesystem on multiple hardware :
      • 4 Dell PowerEdge R740xd ; 1.92TB metadata : RAID-1 array 2 x 1.92TB SSD mixed use MLC disks (or RAID-10 array 4 x 960GB) ; 2x {60 or 72}TB data : 2 x RAID-6 array 8 x {10 or 12}TB SAS 7.2 kRPM disks
      • 2 Dell PowerEdge R730xd ; 800GB metadata : RAID-1 array 2 x 800 GB SSD mixed use MLC disks ; 2 x {36 or 48}TB data: 2 x RAID-6 array 8 x {6 or 8}TB SAS 7.2 kRPM disks
      • infiniband FDR
