Synopsys has been using Conserver for more than a decade. They had
expanded their implementation across the major data centers for the company,
and during 2000, they replaced older ANNEX terminal servers for all Cisco
3600-series hardware, to eliminate Serial BREAK problems.
After attending the LISA 2000 tutorial on Conserver, Jeff Komori architected a
transition to distributed mode multiple Conserver hosts, and they deployed it
across all of their medium and large field offices.
The model for a field office was a Cisco 3640 chassis, with Ethernet, WAN
WICs (Serial and ISDN links), MICA modems, and NM-32A serial modules.
The High-speed serial WAN link and Ethernet continued to play their
traditional WAN/LAN router role. The ISDN and MICA modems provided
high-speed modem dial-up access into the field office, reducing the corporate
dialup costs. And the async serial card provided console access.
The big win was during a WAN link outage, where a Network Admin could see
both sides of the failure, and where console logs turned up configuration needs
on field office hosts when the WAN link was down.
