Clustering for High Reliability
With the globalization of business and the growth in broadband age it has become essential to build IT systems capable of providing service 24x7, free of interruptions and capable of flexible responce to sudden growth of operations.
PRIMECLUSTER is high-reliability backbone software that combines Fujitsu's reliability, and availability technology with leading-edge clustering functionality to meet such IT system needs.
PRIMECLUSTER enables redundant configuration of servers, storage devices, networks and application software. It helps enable autonomous control of all important system resources, (hardware, middleware, applications) via automatic failure detection, high-speed degeneracy and failover. This ensures business operations continue safely. Service uptime is significantly increased, since work can be performed without affecting currently active resources - even during planned outages for periodic maintenance or system reconfiguration.

Continuing server operations
The clustering function manages multiple units of PRIMEPOWER collectively as a single virtual system. In the event of a server problem, this function acts in cooperation with the system monitoring function incorporated in PRIMEPOWER to exercise prompt, reliable error monitoring and to assume control of operations.
What's more, when combined with parallel databases, this function permits servers to be separated or added without stopping the system. It also helps speed up the processing of business operations.
Continuing disk access
A disk-mirroring function permits every PRIMEPOWER disk drive to be redundant. Such redundancy-structured system volumes and disk array devices help achieve secure data protection.
This function also supports volume management of disk drives shared between servers and the construction of a common file system, helping to achieve high-speed, high-reliability storage in a SAN (Storage Area Network) environment.
Network continuity
Another function permits network transmission paths to be redundancy-structured. Even when a network failure occurs, network operations remain uninterrupted by the degeneration and high-speed switching of the transmission paths.
When combined with trunking switches, this function makes it possible to use the redundantly transmission paths concurrentlyto distribute the communication load and further increase bandwidth.
