Technical white paper | HP RA for Red Hat Storage Server on HP ProLiant SL4540 Gen8 Server

Figure 17 illustrates the effect of scaling out both the number of Red Hat Storage Server nodes (in a distributed-replicated

configuration) and clients on random reads. The test used a record size of 1024KB. The 4-node configuration showed more

than double the random read throughput than a 2-node configuration. Increasing the number of client threads had a

detrimental effect on read throughput in a 2-node configuration. The random read throughput doubled when the number of

client threads increased from 8 to 16 but peaked at 24 client threads.
