Kit (GATK) for the variant calling step. These are considered standard tools for aligning and variant calling in whole genome or exome
sequencing data analysis.
STORAGE CONFIGURATIONS
Table 1 lists the configuration details of the three storage systems benchmarked. Default OneFS settings, SmartConnect and NFSv3
were used in all the Isilon tests. A development release of OneFS was used on the F800. Upgrading to the same OneFS version as
used on the H600 would likely yield slightly better results. The F800 also uses 40GbE as a backend network, compared to the H600
which uses QDR Infiniband. OneFS >= v8.1 has been optimized for use with GbE and performs slightly better than QDR Infiniband.

were used during the tests. Table 2 lists Zenith compute node configuration details. The
compute nodes were upgraded from RHEL 7.2 to RHEL 7.3 for the H600 tests.
