OpenAttic aims to provide an open-source alternative to proprietary storage management systems, focusing on unified storage capabilities for both NAS and SAN. Recent developments include the full transition to GPLv2, removal of restrictions, and a comprehensive open-source architecture supporting Ceph management. The initiative emphasizes a user-friendly GUI, scalable management, and community involvement through public roadmaps and bug tracking.

2. openATTIC – Our Vision
─ Develop an open source alternative to proprietary storage
management systems
─ „Traditional” unified storage (NAS/SAN)
─ Support Ceph for scale-out scenarios
─ Backed with commercial support and services

3. openATTIC – Notable Recent Changes
─ Removed Enterprise/Community Edition split
─ Now fully under the GPLv2
─ Removed requirement for CLA
─ DCA (Signed-off-by) is all that's needed
─ Public Jira Bug Tracker
─ Public Pull requests / code reviews on BitBucket
─ Development/Release Branch
─ Entire code base (Backend/WebUI/Test/Docs) in one branch

4. openATTIC – What Sets us Apart?
─ Focus on data center storage management
─ Support both SAN and NAS functionality without limitations
─ Fully Open Source (GPLv2)
─ No arbitrary functional restrictions
─ Low entrance barrier for adoption
─ Based on Linux / OSS tools
─ Multiple Linux distributions (Debian/Ubuntu/Red Hat/SUSE)
─ Well-established technology stack (e.g. drivers, hardware support)
─ Broad user base

5. ─ Modern Web UI
─ RESTful API (Software-
Defined Storage)
─ Unified Storage
─ NAS (NFS, CIFS, HTTP)
─ SAN (iSCSI, Fibre Channel)
─ LVM, XFS, ZFS, Btrfs,
ext3/4
─ Volume mirroring (DRBD®)
─ Multi-node support
─ Monitoring (Nagios/Icinga)
built-in
─ Ceph management and
monitoring (WIP)
─ Development sponsored by
it-novum

6. ─ Backend
─ Python (Django)
─ Django REST Framework
(RESTful API)
─ Linux tools for storage
management, e.g. LVM, LIO,
filesystem utilities, DRBD,
etc.
─ Nagios/Icinga & PNP4Nagios
(Monitoring and Graphing)
─ Web Frontend
─ AngularJS (JS framework)
─ Bootstrap (HTML, CSS, and
JS framework)
─ Uses REST API exclusively
─ Automated Test Suites
─ Python Unit Tests
─ REST Backend Tests
(Gatling)
─ WebUI Tests
(Protractor/Jasmine)

7. openATTIC – High Level Architecture

8. openATTIC – Ceph Management Challenges
─ Managing and monitoring Ceph is complex
─ Many tools exist (e.g. Calamari, Intel VSM, ceph-dash)
─ Limited functionality, unclear roadmaps
─ Finding the best approach for managing Ceph

9. openATTIC – Ceph Management Goals
─ Create a management & monitoring GUI tool
─ A tool that administrators actually want to use
─ That scales without becoming overwhelming
─ Still should allow changes to be made elsewhere, without
becoming inconsistent

10. openATTIC – Ceph Management Implementation
─ Which Ceph Management API?
─ How to manage a distributed system?
─ How to monitor the cluster‘s health/performance?
─ How to perform remote management tasks?
─ How to monitor cluster nodes in a scalable way?

12. openATTIC – Current Ceph Development Status
─ “NoDB” backend architecture / framework in place
─ Create and map RBDs as block devices (volumes)
─ Pool Management Web UI (table view)
─ OSD Management Web UI (table view)
─ RBD Management Web UI (table view)
─ Monitor a cluster health and performance
─ CRUSH Map Editor
─ Support for managing multiple Ceph clusters

14. openATTIC – Ceph Development Roadmap
─ Ceph Cluster Status Dashboard incl. Performance Graphs
─ Extend Pool Management
─ OSD Monitoring/Management
─ RBD Management/Monitoring
─ CephFS Management
─ RGW Management (users, buckets keys)
─ Deployment, remote configuration of Ceph nodes (via Salt)
─ Public Roadmap on the openATTIC Wiki to solicit
