How to run vdbench benchmark on any HCI with X-Ray
By: Date: March 23, 2020 Categories: X-Ray Tags: ,

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….

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…

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…
