There are two local storage areas available on Balena, NFS Home area and a BeeGFS Parallel file-system.
The home file-system has a total capacity of 50TB, but each user is limited to a quota of 5GB. This file-system is connected via 10 Gbps links to the login-nodes, interactive-development-nodes and the visualisation-nodes, and via 1 Gbps links to the all compute-nodes. The home area is backed up and should be used for storing only critical files and small permanent datasets. A user can access their home area via the $HOME environment variable.
/home/[a-z]/[user_name]
$ quota -s
$ cd $HOME $ du -smhc * .[a-zA-Z0-9]*
The BeeGFS parallel file-system has a total capacity of 560TBs and there is no user limit at the moment. This is a non-archival storage area which means it is not backed up. It should be used as the primary data store for all workloads submitted to the cluster. This file-system is connected via 40 Gbps Infiniband links to the compute nodes. A user can access his scratch area via the $SCRATCH environment variable and also from the scratch soft-link in the user's home directory.
/beegfs/scratch/user/[a-z]/[user_name]
$ cd $SCRATCH $ du -smhc * .[a-zA-Z0-9]*
The Campus Storage file-systems is visible from Balena on the Login Nodes, Development Nodes and Visualisation Nodes. These file-systems are external to Balena and is served off other data servers.
The BUCS home which is available via the environment variable $BUCSHOME is the users university home directory which is visible to the user on any Windows/Linux/Mac systems across the campus. On Balena, the $BUCSHOME will be available on the Login Nodes, ITD Nodes and the Visualisation Nodes.
cd $BUCSHOME
NFS mountable research storage (x-drive) can me made available to individual groups. This file-system will be available on the Login Nodes, ITD Nodes and the Visualisation Nodes.
