CRAY XT5m Disk Storage
All user HOME directories for every compute node of the cluster are located on the RAID system of phoenix cluster, shared with the the phoenix Cluster. The compute nodes and login node (frontend) have the HOME directories mounted via NFS. On every node of the cluster the path to your HOME is the same. The filesystem space on HOME is limited by a quota! Due to the limited network performance, the HOME filesystem is not intended for fast I/O and for large files!
For large files and fast I/O, please use
It's a fast distributed cluster filesystem using the infiniband network infrastructure. This filesystem is available on all nodes and on the frontend/loging nodes. The capacity is 5TByte, the bandwidth is about 400MByte/sec.
You are responsible to obtain it from the system. To get access to this global scratch filesystems you have to use the [workspace mechanism].
IMPORTANT! NO BACKUP!! There is NO backup done of any user data located on HWW Cluster systems. The only protection of your data is the redundant disk subsystem. This RAID system is able to handle a failure of one component. There is NO way to recover inadvertently removed data. Users have to backup critical data on their local site!
