High-reliability, High-availability Cluster System Supporting Cloud Environment

Fujitsu is offering FUJITSU Software PRIMECLUSTER, a high-reliability software platform that supports the continuous operation of entire systems. With its highly reliable technology linked to Fujitsu servers (SPARC M10, FUJITSU Server PRIMEQUEST 2000/1000 series, and FUJITSU Server PRIMERGY), PRIMECLUSTER ensures fast detection of malfunctions and secure operational continuity not only in a physical environment but also in a cloud environment, unlike other companies' cluster software. Also, due to a link to the live migration function of the server provided by virtualization software, PRIMECLUSTER enables the server unit to undergo maintenance without changing redundant configurations, or active-standby configurations. This realizes even greater availability for platform systems in a cloud environment. In these ways, PRIMECLUSTER supports continuous operation on a 24/7 basis, even in a cloud environment that integrates a customer's business systems. This paper introduces the technology of PRIMECLUSTER, cluster software that supports platform systems in a cloud environment and business systems running in a cloud environment.
