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 […]

When it comes to assessing fitness of purpose, even audited benchmarks are quite useless unless they incorporate failure testing alongside the load test. I helped develop the TPCx-HCI benchmark which mandates the simulation of a node failure. Who cares about infrastructure benchmarking?
