Hi Antony,
Currently we have 300Tb of replicated and backed up (part of it) storage as we have two data centres on campus. However this is just our toe in the water and we will need a lot more storage. We need to be seen to provide the storage, to create the demand, therefore oversubscription is the key. We would like to offer all our active researchers the minimum of 5Tb of free work in progress storage (RDS). That’s a lot of storage, approx. 14Pb ( if my sums are correct), however this will be phased in, but not to this amount. There will be have to be a PR exercise in bringing in those projects deemed very import, which will then be used to leverage further funding from the University and to try and bring in monies from grant proposals ( however that’s another issue ).
For Tier1 we won't be using 'cloud' storage, however we may do for Tier2. We have 210Tb of Tier2 which is co-located at the University of Nottingham, part of the MidPlus consortium.
On costs, not sure but we are making the case for a sustained opex every year to grow the solution. We are also putting the research data storage on a dedicated research data network, where we can attach equipment that can dump large quantities of data, to the extent that large data transfers can be taken off the University 'user' network.

Hi Aslam, that's quite impressive, so if you have say 100 concurrent research projects you're able to provide 0.5 Petabytes of (RDS) storage for free. Does Tier 1 storage include mirroring and nightly backups or is this 'Cloud' storage and what do you estimate this cost is to the institution?
Regards,
Antony
