operates a storage server for temporary data that does not need backup. Each research group can have their own shares with dedicated storage for their users.
Each group that uses this service usually has a share
that is available to all users of the group.
Optional Dedicated Disks and Disk-to-disk Backup
Research groups with large data needs can buy large quantities of storage buy buying disks. Disks are added to the system in groups of eight at once (RAID6 with 6 disks and two parity). With 10TB drives the usable space would then be 60TB.
We also offer to do daily disk-to-disk backup to a secondary storage server. Research groups just have to buy twice the amount of disks, two groups of eight disks.
can contact our service desk
if they are interested.
Availability and Safety of Data
The system needs to be booted from time to time to upgrade the operating system. This is typically announced to the ITCs
We use server-grade hardware but there is no redundancy on the level of the server. The storage uses RAID 6
on groups of eight disks to make it resilient even to multiple hard drive failures. Snapshots of the file systems protect against accidental deletion.
Access to the shares can be through NFS3 or SMB/CIFS. The available shares for each group are typically worked out with the groups ITC
The list of shares of your group on the scratch space along with the access policies can be found in the section with information for research groups
