Simon is right - we are using DMAPI to tier off to WOS our object store and to StrongBox NAS-fronted tape.
We are very interested in the new “lightweight” protocols as they may allow us to do stuff that DMAPI makes hard - like tiering off to more than one DMAPI service from a single filesystem. If the interface is S3 then it would open the doors to tiering off to any on-prem “cloud” solution that supports S3 sufficiently well ( ours does ;-) ) Cheers, Vic > On 29 Jan 2016, at 15:15, Simon Thompson (Research Computing - IT Services) > <s.j.thomp...@bham.ac.uk> wrote: > > >> Er no the DMAPI was only ever required for HSM as far as I am aware.
