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…

Today we will use the simplest workload that X-Ray provides, the “Four Corners” Benchmark.  This is the classic storage benchmark of Random Read/Write and Sequential Read/Write.  Most people understand that this workload tells us very little about how the storage will behave under real workloads, but most people also want to know “How Fast” will…

In this short series I will describe how to perform performance an resiliency tests on a HCI cluster 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…
