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

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

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

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)

Servers restructuration (1) Go to a “group” structure Map physical to logical structure For example

SRV_EST\Users\FredSRV_EST\Survey\DataSRV_EST\Survey\Archive\PhotosSRV_EST\P32\…

SRV_LHCB\Users\JamesSRV_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

Server OS Preferences Mainly for Manpower consideration

NetWare 4.11 -> NT 4.0 -> Windows 2000 Server-> 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

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

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

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

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

update needed (summer/autumn) Windows NT

SP4 (Y2K) is being applied … SP5 (Y2K) needs to be applied

Windows 95 problems

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 …)

PreferencesMainly 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”

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

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

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
