Charmed Kubernetes and Huawei Oceanstor Pacific storage integration verification report

The verification report is built with Charmed Kubernetes v1.21-v1.23 and eSDK(huawei-csi) v2.2.16.

Project Overview

Background

Huawei OceanStor Pacific is an intelligent distributed storage series with scale-out capability designed to support the business needs of today and tomorrow. Its diverse and adaptable range of features provides efficient processing for diverse data, everlasting operations for services, and economical storage for mass data.

The OceanStor Pacific series supports Storage Access Protocols like NFS, CIFS, POSIX, MPI-IO, HDFS, and Amazon S3. The Block storage allows for SCSI or iSCSI access modes and delivers HA solutions such as distributed active-active and cabinet-level redundancy. It is widely applicable to virtualization, cloud resource pools, and databases.

OceanStor Pacific Storage provides a perfectly reliable, economical, scale persistent storage for PaaS or CaaS (Platform/Container as a Service). The industry scenario includes Channel access PaaS for Internet finance, development and testing PaaS, carrier cloud services for BOM domains and B2B cloud resource pools, smart governments, and Smart City PaaS.

Canonical commercially distributes and supports a pure upstream version of Kubernetes. Ubuntu is the reference operating system for Kubernetes deployments, making it an easy way to build Kubernetes clusters. MicroK8s, a Kubernetes is delivered in the form of snap – the universal Linux app packaging format – which dramatically simplifies the installation and upgrades of components.

Testing Scope

• MAAS auto provisioning KVM virtual machines on 288H V5 machine
• Juju deploys a production charmed Kubernetes cluster
• Huawei csi ( eSDK) integration for Charmed Kubernetes and Oceanstor Pacific Storage
• Using persistent volumes for Containers
• Advanced features of volume extend, clone, snapshot

Testing environment

Conclusion

Huawei Oceanstor Pacific storage cluster can work with Charmed Kubernetes via the Kubernetes CSI plugin developed by Huawei via ISCSI or NFS protocol.  It provides persistent data in enterprise-grade resilient storage, and allows to dynamically provision volumes, make snapshots, and attach them to the containers running in the Kubernetes cluster. This solution allows organizations to move their digital transformation further with a flexible and reliable PAAS or CAAS platform with Charmed Kubernetes.
