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 Jewel release,
|
||
|
|
block-level access is expanding to offer standard iSCSI support allowing
|
||
|
|
wider platform usage, and potentially opening new use cases and
|
||
|
|
customers.
|
||
|
|
|
||
|
|
- CentOS 7.3 or newer
|
||
|
|
|
||
|
|
- 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
|
||
|
|
iSCSI gateway:
|
||
|
|
|
||
|
|
- `Using Ansible`_
|
||
|
|
|
||
|
|
- `Using the Command Line Interface`_
