Paper Title: LINSTOR: A Cluster-Wide Control Path for Storage Management

Paper Abstract: Linstor is an open source project that provides reliable block storage, building on a set of x86 Linux machines with direct-attached storage like HDDs, SSDs or NVMEs. On the software side, it builds on top of LVM or ZFS's zVols, DRBD, and optionally dm-crypt. Support for VDO and NVMe-oF via the Swordfish API is planned. It is currently integrated with Kubernetes, and integration with OpenStack and OpenNebula is being planned. The presentation will provide a rough overview of each part of LINSTOR (LVM, ZFS, dm-crypt, VDO, bcache and DRBD), and it will explain how the parts are orchestrated. It will describe the Software-Defined Storage system as it relates to two other open software efforts: OpenSDS and Stratis. The presentation will also describe how LINSTOR is used in Intel's Rack Scale Design (RSD) effort.
