Whirlpool’s production data warehouse platform in North America is the NCR WorldMark
5100MPP system configured with three 8-way SMP nodes running the Teradata Relational Data Base
Management System (RDBMS) and one 4-way SMP node running Pilot Analysis Server. The 5100M
is directly channel connected to Whirlpool’s MVS mainframe and LAN connected to the corporate
and remote LAN sites. This configuration provides over 200 gigabytes of usable storage to Whirlpool
whose current levels of raw data exceed 90 gigabytes. For development, Whirlpool uses an NCR 4500
4-way SMP server also running the Teradata RDBMS, Pilot Analysis Server, and a development Web
server that provides limited browser access to the data warehouse. The 4500 supports 40 gigabytes
of RAID-protected disk storage.
