Dutch Tier Hardware

• Farm size– now: 150 dual nodes

+ scavenging 200 nodes– buildup to ~1500

up-to-date nodes in 2007

• Network– now: 2 Gbit/s internatl.

(+2.5 Gbit/s experimental)– build-up to >>10 Gbit/s soon (2003?)

• Mass store– Now 120 TByte total, 20 TByte allocated to HEP– will grow such that it’s never* full

*part of national HCP infrastructure with sufficient funds

Support (tools and persons)

• Take many of the tools from DataGrid/DataTAG– farm management by EDG WP4 (NIKHEF involved!)– completely optical networking (DataTAG, SURFnet)

• Security– Long-since established operational DutchGrid CA– Currently supports many VOs (also for national Grids)– IETF/IRTF AAA Arch. chair from UvA/NIKHEF– security towards industrial-grade Grids

• Support staff– 10 fte development staff at NIKHEF,SARA,UvA– dedicated support staff from national E-science project– local grid experts in Alice and LHCb

Embedding of Grids in NL

• Active national projects– Virtual Laboratory for E-Science (VL-E)

(information management, interactive collaborations,…)– Grids for applied sciences and industry (VL-N)– CS-driven “Distributed cluster computer” (DAS-2)– strong national HCP infrastructure (NCF)– lambda networking with NREN (SURFnet)– various grass-roots efforts in universities

• Collaborating in– EU DataGrid– DataTAG– CrossGrid– new proposals for industrial-grade security on Grids
