  1. Plans for NICE Frédéric Hemmer

  2. Outline • Servers evolution • Windows desktop evolution Frédéric Hemmer CERN-IT/DIS

  3. Server: motivations • Stability • Flexibility • Meet individual divisions/experiments expectations and needs • Serviceability & Scalability • Meeting conflicting requirements (e.g. interventions) • Accommodate for different needs (e.g. disk space, 3rd party products) • Reduce diversity • Simplicity (easier to understand problems) • Less effort Frédéric Hemmer CERN-IT/DIS

  4. Servers Issues • Stability • Old hardware • Mixed Ppro@200, PII@300, 256/512 MB, but consistent • Performance problems ? • Complains about slow access (B 112, 197, 73)  Need more analysis • Global organization is division centric • Historical • Does not allow easily to be experiment centric • Changes affect too many people at the same time • Disk space policy • Home directories • “Project” space (divisional servers) • Lack of widespread knowledge of NetWare Frédéric Hemmer CERN-IT/DIS

  5. Recent server instabilities • NetWare expects the task id field in the NCB to be non zero • 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 Frédéric Hemmer CERN-IT/DIS

  6. Groups • A “Group” here is a collection of people sharing : • the same business cycles (e.g. LHCB experiment, administration) • the same files (e.g. Survey photos) • the same third party server tools (e.g. GDPM for SL/ST) • Special needs (e.g. ISOLDE controls) Frédéric Hemmer CERN-IT/DIS

  7. Servers restructuration (1) • Go to a “group” structure • Map physical to logical structure • 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 Frédéric Hemmer CERN-IT/DIS

  8. Server restructuration (2) • hardware rejuvenation (group) • ISP style of rack-mounted servers • External disk shelves  Ease of operation  Scalability • RAID 5  Resilience  Ease of operation Frédéric Hemmer CERN-IT/DIS

  9. Options Do nothing NW 4.11 -> Client32 NW 4.11 -> NW 5.0 NW 4.11 -> NT 4.0 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 Server OS - Options Effort Zero High High Medium ? Huge Frédéric Hemmer CERN-IT/DIS

  10. Server OS Preferences • Mainly for Manpower consideration • NetWare 4.11 -> NT 4.0 -> Windows 2000 Server • We have to support NT anyway • Solves a number of problems • IP only, long file names, accents, 3rd party apps running as a service, … • Limited number of NetWare experts • Introduces a number of problems ? • AppleTalk, NFS, quotas, ACL • Security • Clear migration path to Windows 2000 Frédéric Hemmer CERN-IT/DIS

  11. NT server : impact • Need to deploy NT client on each W95 • Affect roughly 1/3 of the W95 installed base • Users will have to type their password twice the first time • Uses 360 KB of disk space • Need to discuss structure and medium term needs (e.g. disk) with each division • Need to migrate users Frédéric Hemmer CERN-IT/DIS

  12. 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 NT client installed base Installed 39 7 654 182 20 160 247 61 297 139 39 192 6 29 2072 Frédéric Hemmer CERN-IT/DIS

  13. Windows 2000 Server strategy • Involve users from day 1 • Develop desktop independently from server • Prototype Windows 2000 server gradually as of now • Take into account a HEP-wide structure (HepNT) • Independent servers for different functions  Allows for alternatives (e.g. Kerberos)  Allows for component based introduction • Basis for a managed local apps support (roaming user) • Establish Windows 2000 working group • Detailed plan available this summer Frédéric Hemmer CERN-IT/DIS

  14. Potential benefits • “Group” independence • Structure mapped to the organization • Failures isolated • Better serviceability/scalability • Resources more easily mapped to individual requests • One Server OS – leading vendor • Reduce diversity • Management tools easier to develop • 3rd party tools less subject to problems • Windows 2000 Server technologies • Clear statement of direction • Individual needs early taken into account Frédéric Hemmer CERN-IT/DIS

  15. Windows desktop: motivations • Evolving the platform in order to • Meet divisions and experiments expectations and needs (hardware, software, configurations, etc...) • Follow the market • While • Minimizing the changes • Reducing diversity • Being flexible with different needs • Dealing with decreasing effort available Frédéric Hemmer CERN-IT/DIS

  16. Windows desktop today • Windows 95 • Windows NT • Most supported applications are remote • Local NICE Mirror for unconnected Portables Frédéric Hemmer CERN-IT/DIS

  17. Windows desktop short term needs • Windows 95 • At least Windows 95 Year 2000 software update needed (summer/autumn) • Windows NT • SP4 (Y2K) is being applied … • SP5 (Y2K) needs to be applied (summer/autumn) Frédéric Hemmer CERN-IT/DIS

  18. Y2K (examples) Date Tab in Find Files(e.g. 03/20/2003 03/20/C3) Dates in File Manager Date in cmd. int. not valid for 00->79 Date/Time picker Date in Control panel Xcopy /d msvrct40.dll between April 1->8, 2001 Others Large disk (also BIOS issue) Multicast (NDIS.VXD) USB (Scanners, Cameras, etc…) Some apps would not install (e.g. AutoCad …) Windows 95 problems Frédéric Hemmer CERN-IT/DIS

  19. Options Do nothing Windows 95 SP1 Windows 95 OSR2 Windows 98 Windows NT Windows 2000 Professional Problems USB, disk, apps USB, disk, apps All OK ? USB ? Y2K, W98 SE USB, EDH etc. EDH etc. Possible options for Windows 95 Effort needed None Medium¹ High High Medium High ¹ Partly applied, some registry settings incorrect Frédéric Hemmer CERN-IT/DIS

  20. Windows desktop Preferences Mainly dictated by manpower available • Skip Windows 98 • Freeze Windows 95 after Y2K SP + few fixes • Propose move to NT for large disk • Provide missing apps on NT (Diane, etc…) • Prototype Windows 2000 (desktop) - Target MS release + 1-2 months (EOY) NT Issues • Some applications missing on NT (EDH, BHT, HRT ?, but anyway won’t pass Dec. 1999) • USB • Change user perception of NT “slowness” Frédéric Hemmer CERN-IT/DIS

  21. Desktop local applications • Major effort • Issue is how to manage the installed apps • Mgmt Programs would need to be redeveloped • Home directories access may look slow • This seems to be really solved with Windows 2000 Server technologies (IntelliMirror, SMS 2.0) Develop local apps with Windows 2000 Server  Allow for monitored local installs initiated by the user  Home directories are cached in W2K Frédéric Hemmer CERN-IT/DIS

  22. Windows desktop : impact • Some hardware may not run Windows 2000 Professional • 16 bit/DOS applications • Some ISA boards not supported • Change of User interface (active desktop) Frédéric Hemmer CERN-IT/DIS

  23. Potential benefits • Clear evolution path (W95/WNT -> W2K) • Reduced support matrix • For application providers • For service providers • Plug & Play, USB, Large disks • Real OS • Can be done early • But not forcing migration immediately • Allows for legacy application support • Training (if needed) can be staged over time Frédéric Hemmer CERN-IT/DIS

  24. Summary • Go to IP only ASAP • NT client on W95 for non {EP,IT,PS}|{New PC’s} • NetWare -> NT servers • Rejuvenate and restructure Home/Div/Apps servers • Skip Window 98, focus on Windows 2000 • Offer Windows 2000 Professional ASAP • Offer NT alternative for large disks • With local apps managed by IntelliMirror/SMS later • Prototype a Windows 2000 service architecture • Taking account of a HEP wide structure • Allowing for shared sub-services (e.g. Kerberos) • Allowing for early participation of divisions/experiments  Unified architecture with one PC Windows desktop platform in the medium term Frédéric Hemmer CERN-IT/DIS
