SRM2.2 storage workshop

There was a storage workshop held at CERN on the 2nd and 3rd of July. The focus of discussions was on the SRM2.2 developments and testing of the endpoints. The majority of the endpoints are being published in the PPS, the intention being that the experiments will be able to use them in a ~production environment and allow some real stress tests to be run against them. The experiments see SRM2.2 as being an essential service for them, so hopefully they have sufficient manpower to run the tests...

Getting the software installed on the machines isn't a problem, but getting it configured can be tricky. The main point that I tried to highlight on a number of occasions was the necessity for sites to have really good documentation from both the developers (how the SRM2.2 spaces can be configued) and the experiments (how the SRM2.2 spaces should be configured for their needs). I will make sure that I provide instructions for everyone to ensure that the deployment goes (relatively) smoothly. It shouldn't be too much of a problem for DPM sites, dCache sites will need to start playing around with link groups ;-)

From mid-October, sites should be thinking of having these SRM2.2 spaces configured. The plan is that by January 2008, everyone will have this functionality available, and SRM2.2 will become the default interface.
