If you find that you are generating a lot of files and are filling up home directory space or receive a home directory space warning, we have over 300TB of online data storage across several servers.

On the back end, storage is provided using a flexible and dynamically tiered Storage Area Network (SAN) architecture.  The SAN passes data over an independent and redundant 10-gigabit-ethernet backplane using jumbo frames and the iSCSI protocol.  The SAN combined with direct-attached storage resources currently provide over 300 Terabytes of capacity to network users.

Access these shares by using “cd /disk/[volumename]” from most linux computers in the department.  The only linux computers that do not have direct mounting access to these shares (by design) are the NMR and Xray Crystallography acquisition computers and beowulf clusters.  You can also use SSH and SCP clients from Windows / Mac computers.

Each mount point is currently separated into 3 directories, one each for nmr, xray crystallograpy, and cryoem.  Within those folders are folders for each faculty group with the group write permission enabled.  For example, anyone in Angela’s group can create a folder in any of the amglab folders, but not in the ishimalab folder.  If you are unsure where it would be best to store files, see the systems administrator.

All of these storage systems are both replicated and on a nightly backup schedule.  Backups are administered via an expandable LTO-5 robotic tape library system with 240 slots.  Intermediate disk staging of backup sets is used to minimize tape wear and network traffic.  Our magnetic data backup capacity is in excess of 700 Terabytes.
