Why central storage
As a research institute, we certainly hope the following two things:
- All data are easily accessible by all the members, particularly for computing purpose.
- All data are safe, at least for those that are important.
We then start up the central storage system, which is based on the cluster and can be accessed in a straightforward way on the cluster per se. If you wish to access this storage from windows, you have to install an NFS client or use sftp. The most important data are protected by overnight backup.
