IBM Power 795 server


Every large enterprise (LE) relies on critical information. This information is derived from financial data, customer data and enterprise resource data that are held across multiple lines of business. Insights from this enterprise-wide critical information fuel both the core business processes and new services that redefine the customer experience in the LE. To transform the management of this critical information and processes, these organisations rely on enterprise systems that are at the centre of their IT infrastructure. These enterprise systems are defined by their ability to deliver trusted information across the enterprise, ensuring continuous transaction availability and enabling real-time business analytics. They provide the highest levels of security, ensuring the integrity of critical information while mitigating risk and meeting regulatory compliance mandates. They deliver the utmost in infrastructure efficiency at enterprise scale, with flexible delivery models and dynamic resource management that can increase utilisation while reducing operational costs.

The IBM Power 795 server is one of these enterprise systems. The Power 795 supports large-scale transaction processing and database applications within a highly virtualised system infrastructure, enabling new levels of workload consolidation, resource utilisation, resiliency and efficiency. As the most powerful member of the IBM Power Systems family, this server provides exceptional performance, massive scalability and bandwidth to efficiently and concurrently support a full range of complex, mission-critical applications.
