How to create a customized performance test using X-ray.

X-Ray can do the following for the performance tester.

• Model IO workloads using standard fio format
• Create VMs based on user-specified criteria (CPUs, Memory, Number & Size of disks)
• Provision the VMs  to a HCI cluster (Nutanix AHV, ESXi, Hyper-V)
• Execute the workloads
• Display and store the results

In particular X-Ray give the additional benefits that most workload generators do not

• Specify and deploy workloads with different IO patterns and characteristics
  • Most workload generators create a uniform workload on all workers
• Execute and terminate sub-workloads on a user-specified timeline
  • e.g. Begin workload 1 then introduce workload 2 and measure the interference
• Introduce failure scenarios and measure the impact to performance
