“…The z10 core is designed to give the highest performance achievable within the power and heat dissipation constraints defined by the power and thermal system. The System z10 server includes a high-performance cooling system [9] that allows the processor core to run at about 558C. Leakage current is therefore reduced in comparison with air-cooled systems that tend to run at higher temperatures.…”

The IBM System z10e microprocessor is currently the fastest running 64-bit CISC (complex instruction set computer) microprocessor. This microprocessor operates at 4.4 GHz and provides up to two times performance improvement compared with its predecessor, the System z9t microprocessor. In addition to its ultrahigh-frequency pipeline, the z10e microprocessor offers such performance enhancements as a sophisticated branch-prediction structure, a large second-level private cache, a data-prefetch engine, and a hardwired decimal floating-point arithmetic unit. The z10 microprocessor also implements new architectural features that allow better software optimization across compiled applications. These features include new instructions that help shorten the code path lengths and new facilities for software-directed cache management and the use of 1-MB virtual pages. The innovative microarchitecture of the z10 microprocessor and notable differences from its predecessors and the IBM POWER6e microprocessor are discussed.

Data centers are facing serious energy challenges. Increasing energy costs make the operation and cooling of servers more significant cost factors. Furthermore, improvements in technology have led to processor chips and systems with rapidly increasing power density. The resulting power consumption and cooling requirements of these systems are pushing many existing data centers to the limits of their power distribution capability and cooling capacity. Improvements in energy efficiency and management are needed at the chip and the system level to counteract this trend. This paper provides a comprehensive description of the hardware and firmware improvements implemented with IBM zEnterprise A 196 to stop the growth of and even reduce its energy footprint compared with previous IBM System z A servers. These include more power-efficient chips; power conversion and distribution; new sensors; cooling control firmware; new energy management functions; integrated hybrid energy management for power saving and power capping across the whole hybrid system; and data center energy-efficiency improvements resulting from options for water cooling, high-voltage DC (HVDC) power, and overhead cabling.
