1) /home

Globally available, backed up, quotas imposed, moderate bandwidth  
(~400MB/s) and good meta data performance, accounted for based on user


2) /short

Globally available, not backed up, soft quotas allow us to disable  
access to the queue - no hard quotas, high bandwidth (>2GB/s), short  
lived files (if a file isn't access for 3 weeks, we delete it),  
accounted for based on project


3) /jobfs

Locally attached, managed (user allocated space created at the start  
of their job and cleaned up at the end of their job), not backed up,  
moderate-high bandwidth (400MB/s-800MB/s) but extremely high meta  
data performance, accounted for based on job
