Available disk space
Global disk space
The new storage has been installed since October 2017; it is based on BeegFS technology
The entire setup is configured with 8 RAID6 groups of 6 * 10 TB each for data, and each server has a RAID1 group for metadata.
Effective storage capacity: 35.7 * 4 * 2 = 285.6 TB
Your directories
The cluster runs on Linux environment, CentOS Linux release 7.4.1708, kernel 3.10.0-693.2.2
You have 20 GB in your directory /data/home/<user>; THESE DIRECTORIES ARE BACKED UP.
The /scratch space is intended for your calculations, for temporary storage of your data. SCRATCH IS NOT BACKED UP.
A directory /scratch/<user> is available for each user.
Remember to transfer your data regularly.
There are no limits on the use of /scratch; however, users who use it excessively will be warned, and we will clean up accordingly.
| Attention: Following a decision by the users' committee convened in 2015, an automatic purge procedure is in place to move all files older than 8 months to the trash. This trash is permanently deleted after 2 months. This procedure is executed when the storage occupancy rate exceeds 85%. |
