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

Figure 11 illustrates the effect of scaling out the number of Red Hat Storage Server nodes and clients on sequential reads.

The test used a record size of 1024KB. The sequential read throughput is almost the same in spite of increasing the number

of storage nodes with 8 threads (1 client). As we increase the number of threads from 8 (1 client) to 32 threads (4 clients),

we see that the read throughput increases appreciably with all the storage node configurations. The read throughput is

higher with 3 nodes versus 2 nodes but almost the same for 3-node and 4-node configurations.
