Since few months i’m working with VMware vSAN in my own vSphere homelab. And i tell you, i really like vSAN! If you’re looking for an easy, affordable, very well performing and scalable storage solution, there you go. VMware vSAN is ready to take all your workloads. It doesn’t matter if it’s just your nested lab environment, or something more serious like a Virtual Desktop Infrastructure (VDI), big data or business critical applications like SQL databases and Microsoft Exchange servers.
How does vSAN work?
VMware vSAN takes the local disks of an ESXi hosts and puts them in a storage pool, a so called disk group. Put all disk groups of your ESXi hosts together in a cluster and you’ve got a vSAN datastore. It’s that easy. And it’s also easy to make changes to those disk pools. Add disks, remove disks, or change the complete layout of a disk pool.
vSAN max component size
When i recently rebuilt my vSphere homelab i figured out that there was an issue with the disk configuration:
When a capacity disk used for vSAN is smaller than 255 GB (default max component size), virtual machines that run on the vSAN Datastore
