Abstract
For the KEKB controls and operations several Macintosh computers with high-performance CPU's are employed at the central control room.
These were used as computing servers as well as operation terminals. The number of computing servers increased recently in order to process theincreasing volume of operational information. As the number of servers increases, the reliability issues arose how we can meet the upgrade requestsof system and operational software correctly and promptly.Thus, we started to adopt NetBoot, which is a boot-up mechanism through the network.
In this report we present current status of network boot-up and centralized management of calculation servers.
