iSCSI: Block Storage Over the Wire
iSCSI provides block-level storage over your network and is a good way to connect servers and hypervisors like Proxmox or VMware.
When You Need Performance
It is a little technical, but very useful once you try it. iSCSI lets you use network storage like it's a local disk, which suits VM datastores, databases, and high-performance workloads. Once it is set up, you have fast, reliable block storage across your homelab.
