Power efficient components inside every blade


The new BL460c G5 is more energy efficient that our G1 model - basically we took our most popular server and knocked out a minimum 44 watts off of the BL460G1. This equates to approximately 704W per enclosure saved at typical loads, and including cooling that's $2,220 of electrical savings over 3 years at $0.08/kwHr. Here's a few things we did to energy optimize it:
  • Microsoft Windows Compute Cluster Server (CCS)
  • XC Cluster Software
  • Accelrys Materials Studio
  • Simulia/ABAQUS Unified FEA and Platform LSF Solution

Now take that server and run it in c7000 enclosure with the new HP 2400W High Efficiency Power Supplies and take advantage of even more power savings. With increased power output you can allow more blades to run with fewer power supplies, as well as getting the ability to shut off ½ power supply at a time increasing efficiency across the output range.

Add-on technologies to extend power savings

  • Low power memory, processors, and solid state drives options to further reduce energy consumption
  • Patented ActiveCool Fans - increase airflow and reduce power
  • Power efficient architectures: Consolidate, pool & share power and cooling resources across multiple devices
