Nutanix X-Ray Report on VMware Hypervisor


For deploy and configuration Please find Nutanix X-Ray Deploymet and Configuration

This test is performed in Nutanix VMware cluster running on Lenovo Xclarity controller (XCC)

About X-Ray

  • X-Ray open-source performance benchmark tool
  • Test scenario improvements for network bandwidth evaluations I/O testing.
  • Usability enhancements including test prechecks, a direct UI feedback option and improved reporting in single console.

Test Infrastructure Life Cycle

Enterprise clouds leverage hyper-converged infrastructure technologies, mixing compute and storage resources into systems that are then shared by multiple application workloads. When architecting these infrastructures, it is essential to test different real-world data center scenarios to understand how controlled, and uncontrolled situations affect consistent application performance.

X-Ray models and tests typical data center scenarios that

Mirror the infrastructure lifecycle requirements, including pure infrastructure and application performance, performance while using infrastructure data protection features, performance scaling capabilities, and implications of failure scenarios. As shown below, tests have been categorized into typical phases of the infrastructure lifecycle.

Infrastructure Life Cycle Phase

Test: Four Corners Microbenchmark Test Description

This test runs the four data workload types (random reads, sequential reads, random writes, and sequential writes) and shows their peak burst performances. Each of these workloads runs in sequence for 1 minute with 1-minute intervals between. For random reads and writes, higher IOPS indicates better performance; for sequential reads and writes, more bytes per second indicate better performance.

How X-Ray runs the test

Note: This test scales with the number of nodes.

Test Requirements VCPU: 4 vCPU per node. RAM: 4 GB per node.

Cluster storage: 116 GB per node. IP addresses: one per node.


Deploy one workload VM per host. Fill virtual disks with random data.

Run random read workload warmup for 5 minutes. Measurement

Run a random read workload for 1 minute on all VMs. Wait 1 minute.

Run sequential read workload for 1 minute on all VMs. Wait 1 minute.

Run random write workload for 1 minute on all VMs. Wait 1 minute.

Run sequential write workload for 1 minute on all VMs.

X-ray has several built in performance tests which are focused not just on outright performance, but on how a system functions and performs during node failures.

Sequential Read I/O Throughput

X-Ray also provides built-in tests for mixed workloads, which is much more realistic than testing peak performance for point solutions which are become more and more rare these days

Random Write IOPS (Input output per second)

Sequential Write I/O Throughput
