Description
Based on todays understanding of LHC scale analysis requirements and
the clear dominance of fast and high capacity random access storage,
this talk will present a generic architecture for a national facility
based on existing components from various computing domains. The
following key areas will be discussed in detail and solutions will be
proposed, building the overall architecture.
1. large scale cluster filesystems known in the HPC community. This
community has shown the mature character of this technologies
during the last months and evidently this success could be made
usable for the demanding HEP community.
2. methods and systems for decentralized/delegated user
administration. This also includes the integration with VOMS to
allow seamless management with existing system.
3. data access to/from T2 (generally TierX) facilities by using SRM
enabled cluster filesystems and high speed data access to local
TierX storage resources if available.
4. batch process integration presenting exactly the same
interface/behavious to users with resepect to their interactive
ones.
5. accounting and monitoring system to enable true sharing of the
single resource between all participating VOs.
6. criteria showing the scaling properties in the PB data region and
more than 1000 CPUs.
