Oracle's M7 servers are the world’s most advanced systems for enterprise workloads, with unique capabilities for information security, database and Java acceleration. Unique Software in Silicon technology in Oracle's new SPARC processor provides full speed encryption, plus detection and prevention of attacks to critical data in memory. It also enables real time analytics to be performed on OLTP databases by accelerating Oracle Database 12c In-Memory queries. The combination of the world’s highest performance with breakthrough Software in Silicon features is the foundation to building the best and most secure mission critical clouds.

The SPARC M7-16 server offers up to 16 SPARC M7 processors, scales up to 8 TB of memory and has up to 48 PCIe 3.0 (x16) slots. It can be configured with up to four physical domains.

The intent of the power calculator is to provide guidance for estimating the electrical and heat loads for typical operating conditions. It should not be used to calculate power or HVAC requirements. Instead, please use the appropriate installation guide to allow for proper allowances.

Notices and Disclaimers

You MUST allow electrical and cooling headroom for unforeseen circumstances, component upgrades, and increased computational loads. Please allow for worst-case power conditions. Actual power consumption will vary from the sample workload used in the power calculator. These include, but are not limited to, the factors below. Each of these factors may cause significant differences in power consumption:

  • Actual workload and its fluctuations
  • Ambient temperature
  • Cooling patterns
  • Excessive inlet temperature
  • Humidity
  • Operating systems features
  • Power management settings

The "Max Operating Power (35°C)" results shown represent the power consumption measurements with CPUs at 100% utilization and with DE3 Disk Trays at 35C° ambient temperature. The "Typical Power" results represent power consumption measurements taken when system booted and stabilized, yet running at minimal utilization. Sample results shown are representative of measurements taken with room temperatures below 25°C. System power can vary depending upon hardware/software configurations and environmental conditions. For precise results, actual measurements based upon the exact hardware/software/environmental conditions are recommended.
