Traditionally, block-level access to a Ceph storage cluster has been
|
|
|
|
|
limited to QEMU and ``librbd``, which is a key enabler for adoption

|
|
|
within OpenStack environments. Starting with the Ceph Luminous release,
|
2017-07-06 17:32:53 +00:00
|
|
|
block-level access is expanding to offer standard iSCSI support allowing
|

|
|
|
wider platform usage, and potentially opening new use cases.

- A working Ceph Storage cluster, deployed with ``ceph-ansible`` or using the command-line interface
|
|
|
|
|
|
|
|
|
|
- iSCSI gateways nodes, which can either be colocated with OSD nodes or on dedicated nodes
|
|
|
|
|
|
|
|
|
|
- Separate network subnets for iSCSI front-end traffic and Ceph back-end traffic

A choice of using Ansible or the command-line interface are the
|
|
|
|
|
available deployment methods for installing and configuring the Ceph
