New IFS Storage Information
Managed workstations in the group have been updated to connect to the new IFS storage. It will appear as ~/ifs-thom. If this is not shown, please log out and log in again.
For unmanaged machines, one of the following should work:
- Linux CLI (wherever), substituting the appropriate values:
sudo mount -t cifs -o 'domain=AD,username=cen1001,uid=1000,gid=1000,file_mode=0750,dir_mode=0750' //rfs.ch.private.cam.ac.uk/thom
- Mac Finder and some Linux file managers will accept:
smb://rfs.ch.private.cam.ac.uk/thom
- Windows Explorer:
\\rfs.ch.private.cam.ac.uk\thom
Bandwidth Limit for Easter Term 2019
Chemistry Department had to delay the upgrade of their link to CUDN to 10Gbps because the new UIS switches turned out not to support the Department's current resilient connection arrangement. This however has been arranged for after Easter Term 2019. Consequently, the Department's uplink still runs at the same speed as every desktop's individual connection, and so it's very easy for even one person uploading lots of data to the IFS to saturate Chemistry's outward link. If there is a need for bulk upload data before the upgrade of the link, please use rsync with the --bwlimit option or some
other program that can limit its bandwidth. 300Mbps should be safe.
Once the Department gets the outbound link up to 10Gbps this will not be an issue.
