Ceph and Storage Management with openATTICCeph Tech Talks2016-06-23Lenz Grimmer <lenz@openattic.org>

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

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

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

─ 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

openATTIC – Open Source Storage Management

─ 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)

openATTIC – Components

openATTIC – High Level Architecture

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

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

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?
