To build your cloud upon a truly OPEN software-defined storage platform (SDS) you might achieve greater flexibility and $$$$- savings. openATTIC is a SDS cloud storage platform optimized for OpenStack's Cinder component. What is this all about?

- 11. www.it-novum.com © it-novum GmbH Seite 11 Limitations of Commodity Storage (like a simple Linux server or comparable) because of lacking features like: node redundancy & clustering & HA, scaling QoS, Deduplication/Compression, Replication Example: Image Cloning (e.g. image from Glance) could be faster than block-based copy&paste… Limitations of Enterprise Storage (the big names): Vendor lock-in $$$$$ Consider Open Source & SDS ! Choose your underlying storage system!
- 12. www.it-novum.com © it-novum GmbH Seite 12 SDS is the abstraction of the software from the hardware. Benefits: Independence from big-name commercial developer of proprietary systems (bundle of hardware and storage os) for better pricing and freedom of choice Hardware is treated as a pool, scalable across multiple storage systems Innovative functionality (e.g. top-down policy driven), easier to administrate, faster to implement (software can be extended and maintained more easily than hardware) Part of the Software-defined DataCenter (SDDC) By 2016 the avail market for OpenSource-Storage is 2,5$B (Gartner,“Tech Go-to-Market: Storage Providers Should Focus on Three Growth Opportunities Through 2016”, Nov 2013), by 2018 OpenSource Storage will gain 20% of the market , approx. 10$B (Gartner,“2014 Strategic Roadmap for Storage”, March 2014).
