Inktank:ceph overview

  1. 1. InktankDelivering the Future of Storage
  2. 2. About InktankInktank is the company delivering Ceph—themassively scalable, open source, distributed storagesystem. Launched by some of the leadingdevelopers of Ceph, Inktank’s mission is to helporganizations fully leverage the transformativepower of Ceph to decrease storage costs, increaseoperational flexibility and help them freethemselves from restrictive and expensiveproprietary storage systems. Inktank provides best-in-class professional services and support offeringsto enterprises, service providers, and cloudplatforms. Please visit for moreinformation.
  3. 3. About CephCeph, The Future of Storage™, is a transformative, universalstorage system. Ceph is the first and only distributed storagesolution designed to enable object, block and filesystemstorage in a single cluster with unlimited scalability. Theplatform is capable of auto-scaling to the exabyte level andbeyond, it runs on commodity hardware, it is self-healing andself-managing, and has no single point of failure. Ceph is inthe Linux kernel; Ceph can be accessed natively viaprogramming languages; Ceph can be accessed via the Swiftand S3 APIs; Ceph is integrated with the OpenStack™ cloudoperating system; and Ceph is integrated with the ApacheCloudStack project. As a result of its open source nature,this portable storage platform may be installed and used inpublic or private clouds. Please visit formore information.

  5. 5. Traditional Enterprise StorageNot Designed for the Cloud
  6. 6. Traditional Enterprise StorageNot Designed for the CloudNAS File and SAN Block storage • More expensive per gig • Difficult to scale • Provisioning of resources is inefficient • Limited reliability tied to older clustering mechanisms • Hard to manage at scale • Awkward retrofit of scale-up gear to a scale-out worldObject and Block storage are separate systems • Separate systems are inefficient • Lack of interoperability • Result of bolting mismatched technologies together
  7. 7. The Future of Storage Changing Demands Open Source Solution Explosion of Storage Massively Scalable Virtualization in the Cloud Software-Defined Storage Demand for Open Universal Storage System Cloud Efficiency Rapid Provisioning Ease of Operation Self-Managing Cost Pressure Commodity Hardware Readily Available No Single Point of Failure 7
