Figure 9B. Random read performance (N-N)
Random read performance summary:
• Peak read performance of F800 was ~2.7 GB/sec
• Peak read performance of H600 was ~800 MB/sec (32 GB file)
• Peak read performance of H600 was ~3.7 GB/sec (8 GB file)
• Peak read performance of NSS-7.0-HA was ~2.6 GB/sec
• H600 performed better with an 8 GB file vs. a 32 GB file.
Future tests will utilize more than 64 client compute nodes in an attempt to maximize read throughput on the F800 and H600.
I/O Performance Comparisons: F800 vs. Lustre vs. NFS
IOzone has been used in the HPC Innovation Lab to benchmark the Dell HPC Lustre Storage with Intel Enterprise Edition Lustre
filesystem
5
(IEEL3.0). IEEL3.0 is based on Lustre 2.7.15.3. While there are several important physical differences between the three
filesystems, e.g. networking fabric, IOzone results run from similar test cases to the IOR runs can still illustrate approximate
performance comparisons between the three storage systems.
Figure 10 illustrates that sequential read performance on all three filesystems is similar up to the 8-client case. The F800 actually
performs slightly better than the Lustre filesystem. As more clients are added, the Lustre filesystem improves to a peak of
approximately 17GB/sec while the F800 peaks at 13 GB/sec and the NSS-7.0-HA peaks at approximately 6.2 GB/sec.
