An overview of the open source Ceph technology and how Inktank relates to Ceph.

1. Inktank
Delivering the Future of Storage

2. About Inktank
Inktank is the company delivering Ceph—the
massively scalable, open source, distributed storage
system. Launched by some of the leading
developers of Ceph, Inktank’s mission is to help
organizations fully leverage the transformative
power of Ceph to decrease storage costs, increase
operational flexibility and help them free
themselves from restrictive and expensive
proprietary storage systems. Inktank provides best-
in-class professional services and support offerings
to enterprises, service providers, and cloud
platforms. Please visit www.inktank.com for more
information.

3. About Ceph
Ceph, The Future of Storage™, is a transformative, universal
storage system. Ceph is the first and only distributed storage
solution designed to enable object, block and filesystem
storage in a single cluster with unlimited scalability. The
platform is capable of auto-scaling to the exabyte level and
beyond, it runs on commodity hardware, it is self-healing and
self-managing, and has no single point of failure. Ceph is in
the Linux kernel; Ceph can be accessed natively via
programming languages; Ceph can be accessed via the Swift
and S3 APIs; Ceph is integrated with the OpenStack™ cloud
operating system; and Ceph is integrated with the Apache
CloudStack project. As a result of its open source nature,
this portable storage platform may be installed and used in
public or private clouds. Please visit www.ceph.com for
more information.

5. Traditional Enterprise Storage
Not Designed for the Cloud

6. Traditional Enterprise Storage
Not Designed for the Cloud
NAS 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 world
Object and Block storage are separate systems
• Separate systems are inefficient
• Lack of interoperability
• Result of bolting mismatched technologies together
