Why NonStop Server

There are needs for Japanese mobile message service to provide continues operation as it become society infrastructure

Environment to support next generation of @Mail serviceHP NonStopTM server�Opsol Omni Messaging

Released service at July 2002


The Reason for Nonstop Server choice

1�High Availability ----Continuous Operation 24x7NonStop Server achieved 99.9999�highest industry availability. In mobile telephone, telecommunication industry, can not tolerant system down for even one second. NonStop server is the only one capable of delivering 99.9999�availability.

2�Flexible Expandability -----Very Flexible to adopt increase of subscriber NonStop Server can be expanded to 4,080CPU with massively parallel architecture and single system image. It is very flexible to expand system just simply adding cpu, memory, disk, and controllers.

3�Need to reduce TCO by largeNonStop Server can reduce large TCO�Total Cost of Ownership�because system can be managed as single system image, such as reducing number of system operators.

4�Easy to support @mail new services, movie mail distribution KDDI provide high-speed and high- volume of movie mail distribution services which require flexible design of mail box size, because traffic volume will increase and mail size may differ depending ofmovie length. NonStop Server is the only one platform can support this new services and provide its flexibility.
