Overview: Global Filesystems
The Teton global parallel filesystem configured with a 160 TB SSD tier for active data and 1.2 PB HDD capacity tier for less-used data. The system policy engine moves data automatically between pools (disks and tiers). The system will automatically migrate data to HDD when the SSD tier reaches 70% used capacity. Teton has several spaces that are available for users to access described in the table below.

File spaces within the Teton cluster filesystem may be subject to a purge policy. ARCC reserves the right to purge data in this area after 30 to 90 days of no access or from creation time. Before performing an actual purge event, the owner of the file(s) will be notified by email several times for files that are subject to being purged.
Storage Increases on Teton
Project PIs can purchase additional scratch and/or project space at a cost of $100 / TB / year.
Additionally, PIs can request allocation increases at no cost for scratch and/or project space by submitting proposals that must be renewed when substantial cluster or storage changes occur:
the scientific gain and insights that will be or have been obtained by using the system,
how data is organized and accessed in efforts to maximize performance and usage.
Projects are limited to 1 no-cost increase.
To request more information, please contact ARCC.
Special Filesystems
Certain filesystems exist on different nodes of the cluster where specialized requirements exist. The table below summarizes these specialized filesystems.
