Exporting NICE NT to other Institutes Bologna INFN CIEMAT

Exporting NICE/NT to other Institutes: Bologna, INFN, CIEMAT Gian Piero Siroli, Dept. of Physics, Univ. of Bologna and INFN HEPNT Days, CERN, Geneva

Porting - phase I (LAN) u Physics Department at University of Bologna and local INFN branch u u total of about 200 PCs installed and managed individually More heterogeneous environment than CERN, different services, different language for O. S. and applications u Replica u u u of NICE application server Hard disk shipped and then resynchronized over the net ~8 GB compressed (~11 GB total) on NTFS (being tested also at CERN, currently Netware based) Local installation of NICE (source) u u 5 nodes dedicated domain, 10 Base. T Ethernet LAN Site specific code dependencies resolved on 6 projects HEPNT Days, CERN Gian Piero Siroli

Phase I (LAN) u Site u u configuration Security related issues (pair Site. Key/Magic. Key) User creation and configuration u NICE u u services Replicated: Application Support, Scheduled Job Service, Extensions to “System Policies”, Broadcast Message Service, Server Replication Service, Accounting Service Not replicated (because of no immediate interest or CERN specific): Automated Client Installation (Netware), User Registration (private version), Printing Support HEPNT Days, CERN Gian Piero Siroli

Phase I (LAN) u Post u u u u installation Integration into NICE running 2 executables (remote maintenance, NICE desktop installation) Update shortcuts, some applications removed Accounting Service reconfigured W/95 PC reinstalled with Italian version of O. S. (for administrative staff) Logo modification Applications starting correctly Fail-over test PDC-BDC and back Byproduct: some CERN related services immediately available (mail, CERN phonebook, news) HEPNT Days, CERN Gian Piero Siroli

Phase II (WAN) u INFN Computing Committee Working Group u u u Feasibility project of porting and extending NICE infrastructure within INFN (26 sites and 4 labs) Possibility to manage PCs in remote sites with very little or no local manpower Possible mechanism for collaborative work and integration of computing tools within HEP collaborations u INFN-NICE u u test domain One single 18 nodes domain over WAN (<2 Mb lines) + 1 resynchronization node on a dedicated domain 3 BDCs, 3 NICE Application Servers, 2 Home Servers HEPNT Days, CERN Gian Piero Siroli

INFN-NICE test domain HEPNT Days, CERN Gian Piero Siroli

Phase II (WAN) u Tests, u u u u problems and evolution: Remote authentication over WAN (even with only one PDC/BDC) Correct behavior if PDC temporarily unavailable Very slow remote application execution => application servers installed at remote sites Home servers installed at remote sites Centralized accounting over WAN after reconfiguration Site random load balancing and temporary fail-over to remote application servers (if needed) Complete resynchronizations (3 times) of applications and NICE source over the net HEPNT Days, CERN Gian Piero Siroli

Domain architecture (WAN) u Goal: u u u minimize overall management load Personal desktop should follow users on any INFN site Sites must be independent for low level management u 1 single domain: centralized management for high level functions (synchronization, homogeneity of services, security) and better optimization of resources u N domains: complete site independence, trust relationships, security u Models: Single Domain, Single Master Domain, Multiple Master Domains, Independent Domains with trust rel. Consequences on synchronization procedures HEPNT Days, CERN Gian Piero Siroli

Resynchronization u Periodic u u resynchronization with CERN Applications (reference server) NICE source (recompile and reconfigure) Scheme depends on domain architecture Semi-automatic procedure under development HEPNT Days, CERN Gian Piero Siroli

CIEMAT / CENIT (I) CENTRO de Investigaciones Energéticas Medioambientales y Tecnológicas (Madrid) u Under u u deployment Currently running on 60 PCs; 100 to 120 by next week, more will be integrated later Switched Ethernet LAN; maybe another site in the future u NICE installation disk generated for 3 models of 3 COM network cards u TCP/IP protocol, NTFS file system u Printer Wizard: UNIX server running Samba HEPNT Days, CERN Gian Piero Siroli

CIEMAT / CENIT (II) u Roaming profiles u Spanish version of W 95 and some applications u Developed Visual C++ application for user registration u Automatic procedure to integrate PCs running Win 3. 1 HEPNT Days, CERN Gian Piero Siroli

Summary (I) u NICE ported to 2 different environments: Phys. Dept. and Research Center u u u Relatively easy porting and configuration (few days) Little new code development for non ported services “Development/Test” systems in production with satisfactory results u Extension u u to WAN “Stretching” of original CERN-NICE architecture Positive tests Domain architecture: Single Domain INFN W/G proposal: endorsement of CNTC, decision in a short time by CC HEPNT Days, CERN Gian Piero Siroli

Summary (II) u Overall u u u positive experience Very flexible original NICE architecture Robustness Easily exportable: tools and procedures under development to automate installation of NICE in a non. CERN environment HEPNT Days, CERN Gian Piero Siroli
