I’ve recently had several conversations around whether leveraging thin or thick provisioning within a vSAN datastore is necessary. Although the default vSAN Storage Policy leverages thin provisioning, it is important to understand why it is the default and the recommended best practice. Thin vs Thick Provisioning Let’s start with how vSAN defines a thin or thick provisioned disk. Within a […]
With my new role, I am once again drinking from the firehose. The result of which has primarily seen me go heads-down on all things vSAN related, including a course on the new features included in the vSphere 6.7 U1 release. The latest vSAN release included in vSphere 6.7 U1, includes new functionality to support TRIM/UNMAP guest OS commands to […]
The latest release of VMware Cloud Foundation (VCF 3.0) removed the host imaging functionality. As past of the laundry list of pre-requisites for preparing an environment for VCF, one necessary step in an All-Flash vSAN environment is to mark the appropriate capacity disks. During a POC deployment last week of VCF 3.0, this pre-requisite became evident and required a quick […]
IOPS Limit for Virtual SAN Objects Virtual SAN version 6.2 introduced the ability to limit the amount of IOPS a virtual machine object could consume on a per-second basis. Virtual SAN normalizes the IO size, either read or write IO, in 32 KB blocks when it performs calculations. The throttling is specified as part of the storage policy and will […]
I have been heavily involved in designing our next-generation, large-scale hyper-converged (HCI) private cloud architecture at work the past couple of months. As part of that design, we needed a way to easily calculate resources available and cluster sizes using VMware Virtual SAN. When determining the resources available and the effects of the new Virtual SAN 6.2 features, the calculations […]
