Dell POWEREDGE M915 - Manual (Page 9)

Power Efficiency Comparison of the Dell PowerEdge M915 and HP ProLiant BL680c G7 Blade Solutions
9
Table 1: Detailed Blade Solution Configurations
In order to compare the two solutions as closely as possible, each blade server had the same amount of system
memory, and each blade was fully populated with memory: the M915 blades each had 32 4GB RDIMMs for a
total of 128GB system memory, and the BL680c G7 blades each had 64 2GB RDIMMs, also for a total of 128GB
system memory. This configuration also meant that the total number of DIMMs across all blades was 256 per
solution.
Dell only sells low power LV-DIMMs in the PowerEdge M915 blades, so 4GB LV-DIMMs were used for the
comparison. The HP ProLiant BL680c G7 blades only offer LV-DIMMs on their Intel® Xeon® E7-4800 series
4 On the HP Smart Array P410i, RAID 1+0 is the only option available in a 2 hard drive configuration
