- As of 1 Aug 2014, Fermi has 184 TB of 'free space' in the xroot cluster, of which about 21 TB resides on READ-ONLY servers, leaving about 163 TB of accessible free space. At the current rate of consumption and ignoring future reprocessings, this storage could last as long as early January 2015.
- As of 1 Aug 2014 Fermi NFS cluster consists of four 32-GB wain-class servers (128 TB), of which 98 TB (77%) have been allocated. There are 30 TB of unallocated space and 34 TB of unused allocated space. Space, per se, is not an obvious issue with the NFS cluster, and groups of clients have been segregated to independent machines to prevent unwanted interactions between, say, the ISOC data acquisition and LAT user/group disk users. The four NFS user groups currently on their own servers are:
- ISOC
- MonteCarlo/RSP/ASP/Reprocessing
- ReleaseManager
- Users & Groups
