What if I want to automate the process to respond to datastore capacity threshold limits? There are a variety of ways to achieve this. Let’s look at it via vCenter SNMP alerts and vRealize Orchestrator workflows. Continue reading “Automatic VMFS expansion with vCenter SNMP and vRealize Orchestrator”
