Disk Storage Space

Several directories are available to users for storing their data. These directories offer a range of space capacities and vary in speed due to their differing connection types. Some of the locations can be accessed globally (from all pool computers and compute servers) and some only locally. All options should be considered carefully to choose the best fit for the individual use case:

 
Overview of the directories for data storage:
Directory Size Global/Local Speed Features
/dev/shm 16GB-500GB local very fast RAM-FS
/home/tmp

40GB-500GB

local

fast

  

/home/tmp (gruenau[1,2,9,10])

 

 1,8TB local very fast RAID with SSDs/HDDs
/vol/tmp 3,6TB global medium NFS
/glusterfs/dfs-gfs-dist  116TB global medium GlusterFS (replica:0)
/glusterfs/dfs-gfs-dist_repl_2 58TB global medium GlusterFS (replica:2)
/glusterfs/pool-gfs-dist 14TB global medium

GlusterFS (replica:0)
/glusterfs/pool-gfs-dist_repl_3 4,4TB global medium GlusterFS (replica:3)
$HOME ø 10GB/User global medium

NFS, backup on tape

You may access the directories through sshfs and the home directory ($HOME) through Samba/CIFS.
