Single-Layer = servers function as compute nodes as well as storage nodes.
Dual-Layer = servers function only as storage nodes; compute runs on different nodes.
- StorPool Distributed Storage (StorPool) is a service running on a Linux OS, next to the KVM hypervisor, containers or applications. This is a hyper-converged deployment (compute+storage offered by a single layer).
- StorPool is running on dedicated Linux servers and provides virtual disks to external compute hosts – bare metal and / or hypervisors.
- Some of the servers are hyper-converged (compute+storage offered by a single layer), while other servers are dedicated storage nodes or dedicated compute nodes.
