Doc Type: Enhancement
Doc Text:
gluster-block is a distributed management framework for block devices, provided as a command line utility. It aims to make Gluster-backed block storage creation and maintenance as simple as possible. gluster-block can provision block devices and export them as iSCSI LUNs across multiple nodes, and uses iSCSI protocol for data transfer as SCSI block/commands. Block storage allows the creation of high performance individual storage units. Unlike the traditional file storage capability that glusterfs supports, each storage volume/block device can be treated as an independent disk drive, so that each storage volume/block device can support an individual file system. This has utility for a variety of workloads, including database, virtual machine, and container environments.

Description Prasanna Kumar Kalever 2017-02-01 10:54:53 UTC 
Description of problem:
For applications which needs many individual storage units (formatable), at the same time requiring high performance, gluster need to come up with block storage solution. Because sometime it is hard to maintain too many small volumes. For such use cases which needs independent disk drives it will be effective to support block storage capability.

Use cases:
Databases (Cassandra, Elastic search), VM images, Server boot and etc.

Management:
Need to build utilities which help in making it simple and easy to use. Block storage design should qualify for the container use cases(such as Kubernetes) as well.
