Power Efficiency Comparison of the Dell PowerEdge R720 and HP ProLiant DL380p Gen8 Rack Servers
10
Summary
The results of the SPECpower_ssj2008 testing show similar performance between the two systems, with the
Dell PowerEdge R720 having a 1% advantage in raw performance over the HP ProLiant DL380p Gen8. However,
the ProLiant DL380p Gen8 has 15% lower power efficiency overall, and 28% lower power efficiency at the
important 70% load level. This lower power efficiency led to the DL380p Gen8 drawing as much as 53 watts
more compared to the similarly configured R720.
The two-socket 2U server form factor has become a staple in many data centers because these servers strike a
good balance between expandability and rack density. As energy costs rise, power efficiency becomes an
increasingly important factor in the decision to purchase these important data center components. The greater
performance, lower power draw, and higher performance/watt ratio of the Dell PowerEdge R720 make it a
compelling solution compared to the HP ProLiant DL380p Gen8.
