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
One important thing I need to warn you about. We had to delay the upgrade of our link to CUDN to 10Gbps because the new UIS switches turned out not to support our current resilient connection arrangement, and it will now happen after exam term. Consequently our 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. I found this out the hard way when transferring the COs' share. If you have to bulk upload data before upgrade the link, please use rsync with the --bwlimit option or some other program that can limit its bandwidth. 300Mbps should be safe.
Once we get the outbound link up to 10Gbps this will not be an issue.
