Appendix B: Tools used to test and generate data sets
IOzone
The IOzone tool was used to generate data sets used in verification of user case scenarios. It was also
used to establish a baseline with the NSS/NSS-HA configurations. It measure sequential read and write
throughput (MB/sec) as well as random read and write I/O operations per second (IOPS). You can
download IOzon
Version 3.353 was used for these tests and installed on both
the NFS servers and compute nodes used.
dd
The Linux dd utility was used to generate data sets used in verification of user case scenarios as well as
configuration baseline. DD is part of the coreutils package and the version native to RHEL6.1, dd
(coreutils) 5.97, was used.
