Software Defined Storage the Linux way
summary
Linux combines LVM (with thin provisioning), dm‑raid, dm‑cache, targets/initiators and DRBD into a coherent stack and Linstore adds a single control plane that unifies them via a controller and stateless satellites. It implements DRBD synchronous or async replication with up to 32 replicas and dual‑primary for live migration, exposes connectors for Kubernetes/OpenStack/OpenNebula, supports per‑volume dm‑crypt keys, PMEM optimizations and 500k IOPS single volume real‑world numbers, and keeps the controller out of the data path.
