Customer and the latency in my virtual machine is high and my IOPS is not as high as I want it to be. There is A LOT of information here and it pretty much tells you everything you need to know to solve the problem. So nothing is interfering, so while this is not realistic, I think it is still valuable to explain how these things work. One thing to note here, this is one virtual machine running workload to a virtual disk on one VMFS. If you prefer a video, here is my 1 hr VMworld session that goes into depth on what I write below: And frankly not without direct guidance from VMware support. PLEASE do not make changes in your environment at least until you read my conclusion at the end.This workload is targeted specifically to make relationships easier to understand.Mileage will vary depending on your workload and configuration.This is a simple example to explain how queuing works in ESXi.So I put a blog post together of a use case and walking through solving a performance problem. And generally from what I have found it comes down to fundamental understanding of how ESXi queuing works. I have had more than a few questions lately about handling this–either just general queries or performance escalations. Virtual Machine vSCSI Adapter queue depth limit.So I am in the middle of updating my best practices guide for vSphere on FlashArray and one of the topics I am looking into providing better guidance around is ESXi queue management.
