Dell POWEREDGE M915 - Manual (Page 12)

Power Efficiency Comparison of the Dell PowerEdge M915 and HP ProLiant BL680c G7 Blade Solutions
12
The PowerEdge M915 blade solution’s density advantage is illustrated in Figure 3. While both solutions
consume 10U of rack space, the Dell solution can accommodate 8 M915 blades compared to only 4 BL680c G7
blades in the HP solution. This leads to the Dell solution’s 87% advantage in aggregate full-chassis
performance
