CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Plans for NICE Frédéric Hemmer
2
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 2 Outline q Servers evolution q Windows desktop evolution
3
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 3 Server: motivations q Stability q Flexibility q Meet individual divisions/experiments expectations and needs q Serviceability & Scalability q Meeting conflicting requirements (e.g. interventions) q Accommodate for different needs (e.g. disk space, 3 rd party products) q Reduce diversity q Simplicity (easier to understand problems) q Less effort
4
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 4 Servers q Today q Home, Apps, Print servers (NetWare 4.11) q PDC, BDC, Profile, etc. servers (NT 4.0) q Local experiment’s servers (NT 4.0) q Local divisional servers (NetWare 4.11, NT 4.0) q All NetWare servers going to SP6, TSKZERFX.NLM q All NT servers going to SP 4/5
5
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 5 Servers Issues q Stability q Old hardware q Mixed Ppro@200, PII@300, 256/512 MB, but consistent q Performance problems ? q Complains about slow access (B 112, 197, 73) Need more analysis q Global organization is division centric q Historical q Does not allow easily to be experiment centric q Changes affect too many people at the same time q Disk space policy q Home directories q “Project” space (divisional servers) q Lack of widespread knowledge of NetWare
6
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 6 Recent server instabilities q NetWare expects the task id field in the NCB to be non zero q Some applications does not respect this (not identified, maybe nwrdr) TSKZERFX.NLM installed mid-may Servers stable since patch introduction Solution not identified correctly initially Difficult to develop mixed vendors solutions Server failures affected too many people simultaneously
7
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 7 Groups q A “Group” here is a collection of people sharing : q the same business cycles (e.g. LHCB experiment, administration) q the same files (e.g. Survey photos) q the same third party server tools (e.g. GDPM for SL/ST) q Special needs (e.g. ISOLDE controls)
8
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 8 Servers restructuration (1) q Go to a “group” structure q Map physical to logical structure q For example SRV_EST\Users\Fred SRV_EST\Survey\Data SRV_EST\Survey\Archive\Photos SRV_EST\P32\… SRV_LHCB\Users\James SRV_LHCB\Controls\… SRV_LHCB\P32\… Isolation from global server failures Installed software can be under “group” control Local structure under “group” control Allows for easier local administration delegation But need for a “move user” facility Decentralization possible (e.g. PS, Isolde) Division centric Experiment centric } }

CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 14 Windows 2000 Server strategy q Involve users from day 1 q Develop desktop independently from server q Prototype Windows 2000 server gradually as of now q Take into account a HEP-wide structure (HepNT) q Independent servers for different functions Allows for alternatives (e.g. Kerberos) Allows for component based introduction q Basis for a managed local apps support (roaming user) q Establish Windows 2000 working group q Detailed plan available this summer
15
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 15 Potential benefits q “Group” independence q Structure mapped to the organization q Failures isolated q Better serviceability/scalability q Resources more easily mapped to individual requests q One Server OS – leading vendor q Reduce diversity q Management tools easier to develop q 3 rd party tools less subject to problems q Windows 2000 Server technologies q Clear statement of direction q Individual needs early taken into account
16
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 16 Windows desktop: motivations q Evolving the platform in order to q Meet divisions and experiments expectations and needs (hardware, software, configurations, etc...) q Follow the market q While q Minimizing the changes q Reducing diversity q Being flexible with different needs q Dealing with decreasing effort available
17
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 17 Windows desktop today q Windows 95 q Windows NT q Most supported applications are remote q Local NICE Mirror for unconnected Portables
18
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 18 Windows desktop short term needs q Windows 95 q At least Windows 95 Year 2000 software update needed (summer/autumn) q Windows NT q SP4 (Y2K) is being applied … q SP5 (Y2K) needs to be applied (summer/autumn)
19
CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 19 Windows 95 problems Y2K (examples) q Date Tab in Find Files (e.g. 03/20/2003 03/20/C3) q Dates in File Manager q Date in cmd. int. not valid for 00->79 q Date/Time picker q Date in Control panel q Xcopy /d q msvrct40.dll between April 1- >8, 2001 Others q q Large disk (also BIOS issue) q q Multicast (NDIS.VXD) q q USB (Scanners, Cameras, etc…) q q Some apps would not install (e.g. AutoCad …)
