Project Summary

HwameiStor is an open-source local storage solution for cloud-native stateful workloads with High-Availability (HA) capabilities. It will address the limitation of the local volume by a mechanism to enable data drifting with applications.

Project Description

HwameiStor provides a full life cycle management of the local disks (HDD, SSD, NVMe) on the Kubernetes worker nodes. The local disk can be discovered, identified, managed and allocated automatically, besides, HwameiStor will monitor the disk’s health (S.M.A.R.T.) regularly, analyze the metrics to detect any current or potential problem, and process them.

By group the local disks in LVM group, HwameiStor can provision LVM volume in non-HA or HA mode (with HA module). It is trying to address the limitations of the local volume by

1. intelligently locate the data volume replica for the app/pod and schedule it without user interrupt;
2. When reschedule the app/pod across nodes, enable the data volume replica to follow the pod through the features of volume conversion, migration, eviction, etc…

HwameiStor provides a feature of volume group to enable an app/pod to have multiple local volumes, and also can be converted, migrated, evicted as well.

With high-availability replicas in HwameiStor, data can be synchronized & migrated cross-node within the cluster. Storage capacities can also be dynamically expanded (node expansion, disk expansion, volume expansion) to meet the application data persistence requirements.

HwameiStor is easy to deploy and can be installed with HwameiStor-Operator.

Roadmap

Roadmap context

As an enterprise level storage solution, data secutiry will always be our top priority. On the base of HA, we have planned on some data recovery, and data protection features such as snapshot, clone etc.. Observability and performance QoS features are also under our consideration in plan. Data encryption and thin provisioning will be in our future enhancements.

Why CNCF?

HwameiStor is a Kubernetes native local storage system naturally integrated with some CNCF ecosystems' technologies and tools, such as CSI, CRD, Operator, Scheduler，Helm etc.. By contributing this project to the CNCF, HwameiStor can gain access to a wider audience of users and potential contributors, as well as increased visibility and recognition from the community. Being part of the CNCF can also help HwameiStor to stay up-to-date with the latest industry standards and best practices, and to benefit from the experiences and knowledge of other contributors and projects within the CNCF ecosystem.

Benefit to the Landscape

As more organizations move to cloud native architectures, they need storage solutions that can handle the high volumes of data generated by modern applications that can scale dynamically to meet the changing demands. HwameiStor can play a critical role in supporting the data management needs of cloud native stateful applications, such as high performance, high availability, operation and maintenance automation etc..

Cloud Native 'Fit'

HwameiStor is cloud native designed and architectured on Kubernetes CRD mechanism. It is built for cloud native application.

Cloud Native 'Integration'

HwameiStor is working as the storage solution of the Kubernetes cluster to provide data persistency. HwameiStor-Operator is for the system installation and management

Cloud Native Overlap

There are two overlaps with other local storage projects:

First one is LVM module. LVM2 is adopted by HwameiStor for managing local disks and provisioning volume like some other project. In fact, LVM2 is a stable disk management module and popular in most of OS. It’s also easy to deploy and use.

Second one is DRBD module, which is for data synchronization across nodes. Some other projects provision HA volume and rely on DRBD for data syncronization. In HwameiStor, DRBD is one of options for data synchronization. HwameiStor is still trying to add other tools for the data sync, and provides more choice to meet users’ requirements.
