Storage

We maintain several high performance storage systems which amount to about 12.5 PiB total. Listed below are these shared filesystems and the clusters where they are available. We distinguish where clusters store their home directories with an asterisk. The directory /home will always point to your home directory on the cluster you logged into. For more information about storage quotas and purchasing storage see the Cluster Storage page.
