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

Figure 15 illustrates the effect of scaling out the number of Red Hat Storage Server nodes (in a distributed-replicated

configuration) and clients on sequential writes. The test used a record size of 1024KB. The sequential write throughput

shows a moderate increase from 8 to 16 client threads and then flat lines in the case of a 2-node replicated volume. The 4-

node replicated volume doubles the sequential write throughput from 8 client threads to 16, and with subsequent increases

in client threads the write throughput increases moderately. For 16 – 32 client threads workloads, the 4-node configuration

shows twice the write throughput performance when compared to a 2-node configuration.
