2 SUSE Enterprise Storage with Rook

SUSE Enterprise Storage with Rook 7 is an intelligent software-defined storage solution, powered by Ceph technology (https://ceph.com/). Compared to SUSE Enterprise Storage, an alternative deployment stack is used in SUSE Enterprise Storage with Rook.

2.1 What Is New?

SUSE Enterprise Storage with Rook 7 introduces a new deployment stack that is built on two tools: Rook and SUSE CaaS Platform. This containerized Ceph cluster on SUSE CaaS Platform is released with limited availability for the SUSE Enterprise Storage with Rook 7 release. Rook manages Ceph as a containerized application on Kubernetes and allows a hyper-converged setup, in which a single Kubernetes cluster runs applications and storage together. SUSE Enterprise Storage deployed with Rook provides storage to the other applications running within the Kubernetes cluster. This can be block, file, or object storage.

  • SUSE Enterprise Storage 7 is based on Ceph Octopus v15.2.

  • SUSE Enterprise Storage with Rook 7 is running on SUSE CaaS Platform 4.5

  • SUSE CaaS Platform 4.5.0 comes with Kubernetes 1.18

  • SUSE Enterprise Storage with Rook 7 is based on Rook version v1.4.5
