StorageTek SL8500 - Power Calculator

The powerful StorageTek SL8500 modular library system delivers unprecedented value through reliability, consolidation, cost-savings and extreme scalability. It's the eco-friendly choice to meet your most insatiable data storage demands.

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 site planning 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 "Sample Power" results shown (if using 100% workload) represent server power consumption measurements with CPUs at 100% utilization running SPECjbb2005. HPC workloads may consume more power than the commercial workload used in this calculator. If shown for this calculator, the "Active Idle Power" results represent power consumption measurements taken from servers with operating systems 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.
