The breakeven point to go for HP Blade technology


Ever wonder when, power consumption wise, a HP Blade infrastructure is more interesting than regular server ?

Aaron Delp tried to figure it out and compared the power consumption for 16 regular HP DL360’s vs. 16 HP BL460’s Blade. Decreasing that number until the breakeven point.

Here is a short exhibit or his paper that you can read here.

 

They are other reason going for Blade technology that I will summarize here:

1-      Density (reduce space, reduce power, …)

2-      Consolidation (share resources, ideal candidate for virtualization, …)

3-      Manageability (far less cables, one management console, …)
