Storage Overview

Vapor provides a unified storage management interface capable of handling everything from local SATA disks to complex, multi-path Enterprise SAN arrays.

Storage Architecture

Vapor manages storage through several layers of abstraction:

1. Physical Disks: The raw block devices attached to the host (e.g., NVMe, SSD, HDD).
2. Adapters: The controllers interfacing with the storage (e.g., SCSI controllers, iSCSI Software Adapters, Fibre Channel HBAs).
3. Advanced Topologies: Multi-disk configurations like Software RAID, LVM (Logical Volume Manager), and ZFS.
4. Storage Pools: The formatted file systems (Directory, ZFS, LVM, NFS) where Virtual Machine disks, ISOs, and container images are ultimately stored.

In this section, we cover managing the underlying host storage infrastructure. For managing the pools where VMs actually reside, see Virtualization Storage Pools.
