5.1. IPoIB sequential writes and reads
Figure 4 shows the sequential write and read performance. The peak read performance is 4138MB/sec,
and the peak write performance is 1171MB/sec. The design choice of RAID-6 8+2 was to optimize the
service availability and disk layout with the new storage enclosures.
IPoIB large sequential write and read performance Figure 4.
5.2. IPoIB random writes and reads
Figure 5 shows the random write and read performance. From the figure, the random write
performance peaks at the 32-client test case and then holds steady. In contrast, the random read
performance increases steadily beyond going from 32, to 48 to 64 clients indicating that the peak
random read performance is likely to be greater than 10244 IOPS (the performance for 64-client
random read test case).
