IPoIB large sequential write and read performance
Figure 3.
5.2. IPoIB random writes and reads
Figure 4 shows the random write and read performance. The figure shows the aggregate I/O operations
per second when a number of clients are simultaneously writing or reading to/from the storage over
the InfiniBand fabric.
From the figure, the random write performance peaks at the 16-client test case and then holds steady.
In contrast, the random read performance increases steadily beyond going from 8 to 48-client test
cases, and has some drop at 64-client test case, indicating that the peak random read performance is
likely to be around 8699 IOPS (the performance for 48-client random read test case).
