Active space reservationActive space reservation With negotiated sizes and time limits Multiple space reservations for different work Ability to “stage” files with deferred start timeAbility to “stage” files with deferred start time srmBringOnline

7. A. Sim, CRD, L B N L 7 SRM Collaboration, Aug. 2006 Impacts of new deployments All new versions will not communicate with older versions.All new versions will not communicate with older versions. For example, old srmcp for SRM v1.1 will not be able to communicate with new SRM v2.2 based servers. New SRM servers cannot interoperate with older SRM servers in copy case. Both versions will co-exist for a while. Will require community-wide plans and efforts to update SRMs within OSGWill require community-wide plans and efforts to update SRMs within OSG Targeted by ITB 0.8
