End-of-life Systems

In compliance with a recommendation from the most recent five-year review by NSF, SCD established the End-of-Life Systems (EOLS) project to develop definitions and procedures for reviewing all existing supported hardware and software systems in SCD to determine whether support of each system is still justified. Determinations are made as to whether a system is still needed and/or should be retired or replaced. Criteria are primarily economic. For example, is the value of a system worth its support costs and/or can the old system be replaced with one that is more valuable and/or less expensive to support?

Periodic EOLS review is necessary because it is often otherwise difficult to withdraw support allocated to old systems and reassign this support to future endeavors. It is therefore difficult to find resources to support future systems. EOLS review helps to break such a deadlock, and facilitates movement toward the future.

The following hardware and software systems have been completely removed from service in SCD during FY97:

Cray Y-MP/8 (shavano) with associated DS40 and DD49 disk drives
Cray Y-MP/8I (antero)
Cray EL98 (st-elmo)
Cray EL92 (echo)
IBM RS6000 cluster
Text And Graphics System (TAGS)
Dicomed film recorders
Microfiche
Gatorboxes
AppleTalk printers
PACX
xmon monitoring
Macintosh-only Work Request System
netscape v2.0
Microsoft Windows 3.1
Miscellaneous obsolete network equipment: several Alantec Powerhubs, several Cisco AGS+ and IGS+ routers, two FORE ASX-200 ATM switches, a FDDI concentrator, many MTUs and MPRs
Network Systems Corp. (NSC) equipment: EN641 router, FDDI/Cray router (shavano), A130 (shavano), ACT10, HYPERchannel card in lps-gw, FDDI/Cray router (antero)
