Storage Pools
A Storage Pool is the disk space Gallium uses to store virtual machine disk, templates, and related data.
Gallium implements its own storage redundancy, so you don't need to configure hardware RAID. For most deployments, we recommend two SATA, SAS, or NVMe SSDs passed directly to Gallium (not behind a RAID controller).
Pool Modes
Mirror (Recommended) — Data is duplicated across two disks. If one disk fails, the system continues operating on the remaining disk, minimizing downtime and data loss risk.
Single Disk — Uses one disk with no redundancy. Suitable for testing and evaluation environments, not production deployments.
Mirror mode is strongly recommended for any production workload. Single Disk mode offers no protection against disk failure.
Using Hardware RAID
When Gallium is configured on top of a hardware RAID volume, disk health monitoring and failure alerts are unavailable. You must monitor disk health through your server's management interface (e.g. iLO, iDRAC) instead.
To use hardware RAID, present a single logical volume to Gallium and configure the pool in Single Disk mode. Gallium will treat the RAID volume as a single device.
Limitations
Only one Storage Pool is supported per server in Edge. More flexible storage options are available in Gallium Standalone.
