Description
3. Impact
SRM is used by gLite-based Grids as an interface to Storage Elements - indeed gLite has its own implementation, the Disk Pool Manager, DPM. SRMs in the WLCG collaboration together manage tens of petabytes of data (according to the information systems). SRB are used by many "data grids" by, eg. TeraGrid and many national Grids. Being able to transfer data between these two worlds opens up the possibility of analysing existing SRB data on gLite resources. Conversely, we can also make SRM data available to the Globus-based Grids that traditionally analyse data held in SRB, but that is already less difficult.
The important aspect of this work is that it builds on existing tools and requires no development effort. It is Grid Interoperability Now!
4. Conclusions / Future plans
We show how gLite advanced data management tools can be used to manage data not only in SRM, but also from SRBs which are made available as Storage Elements to gLite based Grids. Interoperability is achieved now, with no additional development efforts.
1. Short overview
Using gLite data management tools, we demonstrate data transfers between a Storage Element with a Storage Resource Manager (SRM) interface and a Storage Resource Broker.
Provide a set of generic keywords that define your contribution (e.g. Data Management, Workflows, High Energy Physics)
Data management, SRM, SRB, interoperability, GIN.
If demonstration is requested please explain what visual or interactive aspects of the contribution necessitate a demonstration rather than a presentation or poster?
We can show three windows on a screen, one with files in the SRM, one with an updated view of files in the SRB, and a third window which is used to run the transfer commands. This will also show how quickly the transfers happen.
