For testing the system under stress, the GPU workload was run along with nano and fio tools being run on both the compute nodes.
fio --name=RandomReadTest_Node1 --rw=randread --bs=256k --invalidate=1 --direct=1 --filename=/dev/scinib --size=120 --time_based --runtime=100 --ioengine=libaio --numjobs=8 --iodepth=20 --norandommap --randrepeat=0 --group_reporting --exitall
When running all the workloads in parallel, we achieve an amazing bandwidth of 68 GB/s along with 275,000 IOPS.

From the above tests, we can conclude that the PowerFlex system can run workloads demonstrating high frequency trading and storage intensive workloads like nano and fio without any bottlenecks being observed.
