3. Randy’s Charge to VC C&N
Create an effective, coherent, modern, department wide computing environment
simplify our lives
eliminate artificial barriers and inequities
scale to emerging research and instructional demands
11/19/2018

4. Context Transition over the years Incredible Growth and Change
terminal / shared server (UCBVax, Diva)
many independent workstations + group servers
development of shared infrastructure services
SWW + Auspex home directories, ...
Incredible Growth and Change
3500 IP addresses in EECS, CS. PCs everywhere
ethernet/FDDI -> FDDI -> ATM -> switched ethernet -> 1000BT
Cory net, soda net
multicast NT
Linux
\cs\ grown from 300 GB to over 1 TB in one year
600 GB of NT Clustered storage (dept. wide prototype)
1.5M$ per year into instruction in two years
11/19/2018

5. Situation Today Powerful Infrastructure Services on the Network
file, information, name, mail, time, web, ftp
directory, calendar
Rich desktop environment
not just config and shell scripts
plugins, registries, ...
NT reaching par with Unix
PCs widespread
Small devices emerging
Users are pretty confused
who do I go to for what? What should work?
Vast unmanaged machine assets
constant breakins
11/19/2018

6. Faculty Survey (9/99) 66% - comp. infrastructure limits their teaching
55% - comp. infrastructure limits their research
Happiness on scale of 10
desktop 6.2
networking 6.1
infrastructure 5.9
instructional 5.5
lab 5.4
classroom 4.9
new user 4.5
12% say they spend too much on computer support
they had dedicated staff
11/19/2018

7. Staff Situation TCS disbanded in 1/1/97
Split dept (IESG) and ERL (CSG)
stemmed the tide of red ink and retired debt
several tech staff reporting to MSOs
CS infrastructure provided by Titan NSF grant
ends soon (6/31/99 + extension)
Unclear who is responsible for what
project planning and mgmt difficult
Unclear what pays for what
NAF ??
CSG Contracts ?? Cory Infrastructure??
CSG recharge, IESG recharge
General unease
is instruction subsidizing research or vice versa?
11/19/2018

8. Outline of the Emerging Enterprise
Research
Instructional
EECS Wide Services
Integrated Unix/NT
Single user directory (LDAP)
feeds (or replaces) Unix NIS, NT DS
everybody has both accounts
Single resource database
every machine has a current administrator
Common set of services across NT/Unix, Research/Instruction, Soda/Cory
users, groups, files
server-based mail (IMAP)
Scale to need (and quickly)
11/19/2018

9. Scalable Storage and Info Service (Unix)
Dept Networks
Information Servers
NT FS
RAID Storage Servers
Redundant
Cluster Network
Web FTP
pop
imap
(1.2 TB)
LDAP
DNS/ NIS
Redundant Backup Server
Consolidate with Cory facilities
11/19/2018

10. NT Transition Plan Provide RAID storage with backup
EECS

11. New Staff Structure Form One Infrastructure Group
shared across ERL/EECS
drawn from Titan, CSG, Dept, IESG
Focus user support on Users!
Free up instructional efforts from duplicating infrastructure
Focus electronics support on labs, AV, and Devices
Dept. Networked Systems Architect to lead, guide, develop, and manage the enterprise
Clear, simple funding model

15. It’s broke! Who do you call?
Office desktop computer? => CUSG
unless you hire your own admin
Classroom? Computer Lab? => ISG
Device? Electronics Lab? Wires? => ESG
If it’s under the floor or in the machine room, IDSG is responsible
front-line staff should do the isolation and make the call
IDSG deals with IS&T as needed
11/19/2018

16. Function: IDSG The Network (subcontract to IS&T as approp)
The Shared Servers
Common Binaries (SWW, NT-SWW)
Services
time (NTP), names (DNS), configuration (DHCP)
directory (LDAP), NIS, NT DS
file (NFS, NTFS, Samba)
mail, messaging, news (IMAP, POP, Exchange)
User, calendar
Web, FTP, Print
Backup (services and files)
Management
Security
Disaster recovery
11/19/2018

17. Function: CUSG High quality user support on contract
user account, support, questions, documentation
system configuration (standardized)
proactive system tracking, upgrade, monitoring
periodic user environment checkups
helpdesk: problem notification, diagnosis, correction, and tracking
escalating priority of open problem reports
90% resolution within two days
security issue resolution
Time and materials support
off-contract assistance
special system support
Subcontract HW support
Development of support and management tools
11/19/2018

18. Function: ISG Efficient support of instructional computing
more narrowly focused base of systems, applications, user configuration
large user population
uniformity
Development of advanced instructional infrastructure
changing faculty teaching needs
new technology
grants, donations, campus liaison
11/19/2018

19. Function: ESG
Development and support of instructional electronics labs

28. Outstanding Thorns Modems Transition of capital equipment and debt
48 instructional, 64 ERL (14.4 and 28.8)
aging, but inexpensive to carry
expensive to replace
will need to find alternative (SHIP, IS&T, …)
Transition of capital equipment and debt
AV funding model
Eventually need alternative to tape backup
11/19/2018

29. Discussion We’re a long ways towards it
CS Pleiades is solid and scalable
EECS NT-SWW as start
EECS NT home coming soon
Soda/Cory networking
Staff has been working across groups as a team
division by function, rather than by platform
Planned switch-over July 1, 99
Titan will smooth the transition
Should we fold in port costs too?
