Since all our global disks are served from Linux or Unix platforms, the following list is viewed from that perspective. Where the disk is primarily for Windows use, this is noted. In the context of this page, "disk" should be taken to mean "disk partition" - I don't try to provide information on the physical disk organisation, though I do indicate the host for the disk space.

General areas:

/usera (4TB on cluster) - contains Linux home directories
/pchome (200GB on cluster) - contains Windows home directories
/pcshare (50GB on cluster) - Windows software
/cern (10GB on cluster) - CERNLIB software
/project (200GB on cluster) - Undergraduate Project Student working space
/pc_backup (200GB on cluster) - Windows communal file space
/cad (20GB on cluster) - Linux CAD files
/web (50GB on www) - web server files

Experimental areas:

/atlas (300GB on cluster)
/calice (200GB on cluster)
/lc (300GB on cluster)
/lhcb (300GB on cluster)
/minos (300GB on cluster)
/na48 (10GB on cluster)
/opal (10GB on cluster)
/theory (50GB on cluster)

Data areas:

/r01 (8TB on cluster)
/r02 (35TB on pcjm)
/r03 (20TB on pckn)
/r04 (20TB on pckn)
/r05 (30TB on pcle)
/r06 (30TB on pcle)
/r07 (30TB on pclf)
/r08 (30TB on pclf)

Scratch areas:

/work (200GB on cluster) - global scratch area
/var/work (variable amount on each Linux computer) - for local scratch space. Each of these areas is available on all computers via /var/work/pcxx
