The problem that high-cost UNIX terminals cannot be wiped out

Toyodenso's (hereinafter, TEC) vehicle electrical components, which are used around the world, are designed and developed at the company's technical center. The high-end 3D CAD software used for design was UNIX-based, but the new version is Windows-based, so we had no choice but to maintain different design environments for UNIX and Windows, resulting in double terminal costs and management costs. was
"If possible, we wanted to cancel all old UNIX terminals and migrate to the new version, but there was no compatibility between the two, and some customers still requested to provide data on the old version. However, it was necessary to use the old version to partially modify the existing drawings.Therefore, it was necessary to continue to secure the infrastructure of the old version.” Mr. Takahashi, the section leader, looks back on the problems at that time.

EoDは「コストが見合う」ソリューション

Using the old version required a very expensive UNIX terminal, but the lease and maintenance fees were not justified by the frequency of use. Since the use of the old version is limited and will end in the future, the major issue was how to operate the transition period to the new version at low cost and to meet the needs of customers and the company. At that time, he learned of the existence of PC X Server EoD, a solution that greatly reduced costs and reduced man-hours for management and operation.

EoD is a PC X server that can operate X applications on UNIX and Linux hosts from a Windows terminal via the network, but it does not require high specs on the client side, so Windows terminals for OA can be used. "We didn't need to prepare an expensive UNIX terminal, and it was a solution that perfectly matched the Company needs," says Mr. Takahashi. The company started EoD verification in May 2009.

"We used one UNIX terminal as a server and turned it into a multi-user system. We ran applications on 12 machines at once and analyzed the load status in detail to see if it would interfere with our operations. By reviewing the operation rules, we were able to We were able to confirm that it is possible to create an operational environment that does not affect the environment, and after a month, we decided to officially introduce it.” (Mr. Takahashi)

Multiple advantages of using Windows on terminals

"More than a year has passed since the introduction of EoD, but no problems have occurred. By reducing the number of UNIX terminals, we were able to reduce the terminal maintenance cost to 1/12. In addition, we have one Windows terminal. Both UNIX-based and Windows-based versions can be operated with , and there were major advantages in terms of greatly improving usability, reducing the power consumption of the terminal, and saving space," concludes Mr. Takahashi.
