[Go-essp-tech] DRS hierarchy on disk

[stephen.pascoe at stfc.ac.uk]

At the telco this Tuesday I was slightly surprised when someone (I think
Bob) asserted data is not likely to follow the DRS hierarchy on disk.
Although we know the disk layout can be mapped to DRS URLs in the web
server I thought our default position was that we would lay out the data
in the DRS hierarchy because it is the simplest solution.
 
This issue came up in a meeting with UKMO yesterday where they thought
there was a strong reason for using the DRS on disk so that fallback
positions like ftp follow a consistent structure.  I also learnt that
CMOR2 will output to the DRS hierarchy automatically.
 
Given this, why wouldn't we want to insist all datasets are stored on
disk in the DRS hierarchy?
 
Thanks,
Stephen.
