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,
block-level access is expanding to offer standard iSCSI support allowing
wider platform usage, and potentially opening new use cases.
- Red Hat Enterprise Linux/CentOS 7.5 (or newer); Linux kernel v4.16 (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:
