Baldor Electric is a global
manufacturing company with
headquarters in Arkansas,
USA. It has 26 plants in the
US, Canada, Mexico and
China, selling industrial electric
products to more than 70
countries.
Baldor couldn’t ensure 24x7
availability to provide quality
service to customers and
employees and eliminate the
risk of business disruption. At
the time, outages occurred
five-to-eight times a year,
costing hundreds of thousands
of dollars.
• By moving workloads to virtual
machines on IBM System z
running SUSE Linux
Enterprise Server for System
z, Baldor Electric Company
reduced IT costs from two
percent of sales to less than
one percent—while improving
response time, up-time and
productivity.
• “The platform goes beyond
five 9s,” says Eric Breuer,
Manager, Large Systems,
Baldor. And the new
environment results in
considerable time savings for
planned downtime.

30% lower hardware and
software costs.
90% consolidation of servers
(resulting in lower space,
cooling and power costs).
90% improvement in up-time
(reducing disaster recovery
losses).
“We believe SUSE has the
best Linux distribution with the
best support. The platform
goes beyond “five 9s,” and the
new environment results in
considerable time savings for
planned downtime.”
