LINSTOR grows beyond DRBD

For quite some time, LINSTOR has been able to use NVMe-oF storage targets via the Swordfish API. This was expressed in LINSTOR as a resource definition that contains a single resource with one backing disk (that is the NVMe-oF target) and one diskless resource (that is the NVMe-oF initiator). Layers in the storage stack In […]
