This article explains how storage pools are configured in StorMagic SvHCI, how the default boot pool is used, how additional storage pools can be created, and how licensing capacity is applied.
Understanding SvHCI Storage Pools
Learn how SvHCI storage pools are created, how they are licensed, and how they are used to store virtual machine disks and ISO images.
Overview
Within SvHCI, a storage pool is configured to hold both ISO images and guest virtual machine disks.
The pool performs a similar role to a VMware VMFS datastore, with guest virtual machine disks synchronously mirrored (RF2) across the SvHCI nodes.
A storage pool may be created on:
- Hardware RAID (for example RAID 5 or RAID 10)
- SSD or HDD storage
- Software RAID 0, RAID 1 or RAID 10 created from individual drives
During installation, SvHCI automatically creates a boot pool using the remaining capacity of the installation disk. This allows systems with a single RAID volume to host both the operating system and guest storage without requiring dedicated boot media.
Boot Pool
SvHCI automatically creates a boot pool using the remaining capacity available after the operating system installation partitions have been created.
Default boot pool
The boot pool consumes licensed capacity and may be used for storing guest virtual machine disks and ISO images.
This design allows servers with a single RAID volume to operate without requiring separate boot storage.
Additional Storage Pools
Additional storage pools can be created using extra storage devices installed in the server.
These pools may be created from hardware RAID volumes.

Alternatively, software RAID 0, RAID 1 or RAID 10 may be configured directly across individual storage devices.

Pool Licensing
Each SvHCI license includes a storage capacity entitlement.
Licensed capacity is consumed based on the configured pool size rather than the raw disk capacity installed in the server.
Pool licensing capacity
The licensed capacity assigned to a pool can be increased or decreased using the License Pool Capacity option.
Limit a pool to a licensed capacity
After restricting the licensed capacity, the pool displays the updated available free space based on the configured limit.
