OpenEBS is a Software Defined Storage (SDS) platform, written in GoLang, that provides the block storage containers called Virtual Storage Machines or VSMs. A VSM is a fully isolated block storage container, has it's own iSCSI stack, full set of storage management APIs and can back up the application consistent data to another VSM or an S3 compatible storage.
OpenEBS can scale to millions of VSMs seamlessly as it manages the metadata of the block storage system at a file level. The block storage for each VSM is managed as one single file or directory. The IO to this file is managed through large size chunks rather than the typical small size blocks. This enables to OpenEBS to provide higher performance for each VSM and to easilyh scale to very large number of VSMs.

- VSMs are containers running on Docker (https://github.com/docker/docker)
- Persistent Storage and Replication for OpenEBS VSMs from forked Rancher Longhorn (https://github.com/openebs/longhorn)
- iSCSI Frontent for OpenEBS VSMs from forked gostor gotgt (https://github.com/openebs/gotgt)
- VSMs are managed and scheduled via HashiCorp Nomad (https://github.com/hashicorp/nomad)
