In today’s fast-paced business environment, all enterprises, from the world’s largest companies to the smallest depend on IT. Enterprise resource planning (ERP), customer relationship management (CRM), and business intelligence (BI ) all require that transactions are quickly processed and that the resulting data is reliable as to meet the requirements of the rapidly changing business environment. The need for higher performance and better reliability is growing exponentially in enterprise I

Mainframe-class RAS Features RAS Design Philosophy Realization of a mainframe-class continuous operation through the pursuit of reliability and availability in a single server construct Generally, in order to achieve reliability and availability on an Continuous operations throughout failures; minimize the open server, clustering would be implemented. However, spread of failures; and smooth recovery after failures were clustering comes with a price tag. To keep costs at a minimum, goals
