CONCLUSION
Dell PowerEdge C5220: Hadoop MapReduce Performance
We used mrbench to create datasets containing varying numbers of records,
which each contained 6 bytes, for datasets varying in size from 96 bytes to 9,600,000
bytes. We tested two mrbench configurations; in the first, we applied 16 maps and one
reduction process to those input recordsets, and in the second, we applied 160 maps
and 16 reduction processes to those input recordsets.
Figure 4 shows the time in milliseconds the cluster took to complete each job
when we applied 16 maps and one reduction process to those input recordsets.

Companies that wish to process big data in scale-out environments require
powerful and dense hardware that complete large data processing tasks, such as
Hadoop analysis, quickly and efficiently. Selecting the right server for your underlying
hardware infrastructure is critical at hyperscale.
In our tests, an eight-node Dell PowerEdge C5220 Hadoop cluster was able to
efficiently process multiple MapReduce scenarios. While each scenario and each
environment vary, our eight-node Hadoop MapReduce test shows that even a small
number of Dell PowerEdge C5220 microservers can process varying amounts of data
quickly.
