 1. The replicas function like a networked disk, supporting read/write operations over a network protocol.
 1. The frontend (only Open-iSCSI/tgt are supported at this moment) is a kernel driver that translates read/write operations on the Longhorn block device (mapped at `/dev/longhorn/vol-name`) to user-level network requests on the controller.
 1. Each Longhorn block device is backed by its own dedicated controller.
