1 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 } }

9 CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 9 Server restructuration (2) q hardware rejuvenation (group) q ISP style of rack-mounted servers q External disk shelves  Ease of operation  Scalability q RAID 5  Resilience  Ease of operation

10 CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 10 Server OS - Options Options q Do nothing q NW 4.11 -> Client32 q NW 4.11 -> NW 5.0 q NW 4.11 -> NT 4.0 q NW 4.11 -> Windows 2000 Server Problems No IP, 8.3, accents UI, depl., Home, NT, IP OK? Expertise, migration NT client, quotas, BU Too early Effort Zero High Medium ? Huge

11 CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 11 Server OS Preferences

12 CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 12 NT server : impact q Need to deploy NT client on each W95 q Affect roughly 1/3 of the W95 installed base q Users will have to type their password twice the first time q Uses 360 KB of disk space q Need to discuss structure and medium term needs (e.g. disk) with each division q Need to migrate users

13 CERN - European Laboratory for Particle Physics Desktop Forum - June 30, 1999 Frédéric Hemmer CERN-IT/DIS 13 NT client installed base Division AS DSU EP EST FI IT LHC PE PS SL SPL ST TH TIS Total Not Installed 8 1 12 98 23 5 117 39 0 255 54 105 0 25 742 Installed 39 7 654 182 20 160 247 61 297 139 39 192 6 29 2072

14 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
