IBM Power 795 server Extraordinary scale, capacity and bandwidth for the most demanding enterprise applications For large-scale server consolidation to increase flexibility and lower operational and energy cost For enterprises requiring the highest levels of resiliency for their mission-critical applications For data centers supporting the largest UNIX and IBM i transaction processing and database applications Every large enterprise 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 large enterprise. To transform the management of this critical information and processes, these organizations rely on enterprise systems that are at the center 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. And they deliver the utmost in infrastructure efficiency at enterprise scale, with flexible delivery models and dynamic resource management that can increase utilization 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 virtualized system infrastructure, enabling new levels of workload consolidation, resource utilization, 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.

Equipped with up to 256 POWER7® processors the Power 795 server can scale rapidly and seamlessly to address the changing needs of today’s business climate. Equipped with industry-leading PowerVM® virtualization, EnergyScale™ technology and affordable Capacity on Demand (CoD) options (including a specific number of Elastic CoD processors and memory days, dependent on the configurations that come standard with all new Power 795s), the Power 795 helps enterprises increase their productivity and effectively consolidate multiple UNIX, IBM i and Linux workloads onto a single system. Extensive...

and additional clock speed. Based on the user’s configuration option, a Power 795 system can boot in MaxCore mode, enabling up to 256 processor cores running at 4 GHz or in TurboCore mode, enabling up to 128 processor cores running at 4.25 GHz with twice the cache per core, providing increased f lexibility to optimize the system to an enterprise’s specific application processing demands. Also with POWER7 is the ability of the processor to run at a higher frequency if environmental conditions permit, resulting in increased performance; or alternatively run at a lower frequency if user...

Extraordinary scalability and capacity Up to three I/O drawers may be installed in the initial system frame, each drawer providing 20 PCIe adapter slots and up to 26 SAS hot-swap Small Form Factor disk bays. To provide ample room for growth and capacity, expansion frames are available to support up to 29 additional I/O drawers. The Power 795 server is designed to grow with a business by offering extraordinary scalability and configuration flexibility. Processor books, memory, I/O drawers, adapters and disk bays can be easily added to realize the potential power and capacity of the system....

dynamic failover; IBM Chipkill ECC memory with additional DRAM sparing; First Failure Data Capture mechanisms to log and help prevent the recurrence of intermittent failures that diagnostics cannot reproduce; and dynamic de-allocation of system components, including processors and PCI bus slots, to help reallocate resources when an impending failure is detected so applications can continue to run unimpeded. All of these functions help to increase system availability and allow more work to be processed with less potential for disruption. In addition, a new availability offering for the Power...

Enterprise-class PowerVM virtualization allows for automatic nondisruptive balancing of processing power between VMs assigned to the shared pools, and Shared Dedicated Capacity, which helps optimize use of processor cycles. PowerVM Enterprise Edition includes all the features of Standard Edition plus Live Partition Mobility1 (LPM), PowerVM Active Memory Sharing2 and PowerVP (virtualization performance monitoring). PowerVM is the family of technologies, capabilities and offerings that deliver industry-leading virtualization on IBM POWER processor-based systems. On the Power 795, PowerVM...

Workload optimization Available with all POWER7 processors is the ability of the processor to run at a higher frequency if environmental conditions permit, resulting in increased performance; or alternatively run at a lower frequency if user settings permit, resulting in greater energy efficiency. Operating in concert with IBM Systems Director Active Energy Manager, this feature enables customization by partition for maximum performance, maximum energy savings or a mixture of both. New for the Power795 is a hardware feature called Dynamic Platform Optimizer. This feature monitors processor...
