olympia.ard.de (=olympia.br-online.de), 1/2002. Web services "Olympic Games, Salt Lake City" for the German ARD with 2 IBM Netfinity a.k.a. x350 (4 CPUs, 2 GB RAM, 280 GB RAID5), heartbeat over 2 serial null modem cables, local iptables(8) firewall, rsync(8)-based data import by the inhouse staging and deploying system . System took a hit because of a typo, and heartbeat(8) took over once during the games. Nobody took any notice of it during the games ;-}. Gone to archive in 6/2002.
LVS evaluation cluster, 5/2002. Heartbeated (redundant) load balancer on 2 IBM x330 (2 CPUs, 1.2 GB RAM) with Linux LVS on Kernel 2.4.18, heartbeat over 1 serial and 1 ethernet cross cable connection which is also used by rsync(1) for data consistency. Worked great and is currently fall back solution if problems with BigIron switch persist.
firewall gateway internet-dmz, 7/2002. Hardware and system id. to "LVS evaluation cluster", plus 7 NIC ports and iptables firewall. It was a bit messy to include patches for 4-port-NIC D-LINK DFE-580TX into Kernel 2.4.18. System is up and running. The systems will migrate from HD to CDROM (diskless).
Several other installations are expected to be completed in 2002 and beyond. These include a firewall router (dmz-intranets), NFS fileserver, Samba file server, Oracle, MySQL and Postgres databases.
GREAT app, works perfectly. I would be happy to contribute with tech and work. Werner Schultheiß, Letras Berlin-Munich, 20020925.
