Note: Though the Dell PowerEdge R730xd server provides flexibility in the layout and configuration of
I/O subsystems, the combinations described in Table 2 were selected on the basis of performance data
of different configuration variations tested.
After extensive performance and server scalability evaluation and testing, Red Hat and Dell have classified
the benchmark results into the following five categories:
 Compare server throughput in different configurations
 Compare overall solution price/performance
 Compare overall solution price/capacity
 Compare server throughput in replication versus erasure-coded modes
 Compare server throughput in JBOD and RAID0 modes
These five comparisons are shown in section 4 of this document.
