How to run vdbench benchmark on any HCI with X-Ray

Many storage performance testers are familiar with vdbench, and wish to use it to test Hyper-Converged (HCI) performance. To accurately performance test HCI you need to deploy workloads on all HCI nodes. However, deploying multiple VMs and coordinating vdbench can be tricky, so with X-ray we provide an easy way to run vdbench at scale. […]

Working with fio “distribution /pereto” parameter

Published: (Updated: ) in Nutanix, X-Ray, , by .

The fio Pareto parameter allows us to create a workload, which references a very large dataset, but specify a hotspot for the access pattern.  Here’s an example using the same setup as the ILM experiment, but using a Pareto value of 0:8.  My fio file looks like this.. [global] ioengine=libaio direct=1 time_based norandommap random_distribution=pareto:0.8 The […]

X-Ray scenario to demonstrate Nutanix ILM behavior.

Published: (Updated: ) in X-Ray, , by .

Specifically a customer wanted to see how performance changes (and how quickly) as data moves from HDD to SSD automatically as data is accessed.  The access pattern is 100% random across the entire disk. In a hybrid Flash/HDD system – “cold” data (i.e. data that has not been accessed for a long time) is moved […]

HCI Performance testing made easy (Part 4)

What happens when power is lost to all nodes of a HCI Cluster? Ever wondered what happens when all power is simultaneously lost on a HCI cluster?  One of the core principles of cloud design is that components are expected to fail, but the cluster as a whole should stay “up”.   We wanted to […]

Creating a HCI benchmark to simulate multi-tennent workloads     HCI deployments are typically multi-tennant and often different nodes will support different types of workloads. It is very common to have large resource-hungry databases separated across nodes using anti-affinity rules.  As with traditional storage, applications are writing to a shared storage environment which is necessary to […]
