The plan, Stan

Welcome!

4

On commodity hardware

Ceph can run on any infrastructure, metal or virtualized to provide a cheap and powerful storage cluster.

Object, block, and file

Low overhead doesn’t mean just hardware, it means people too!

Awesomesauce

Infrastructure-aware placement algorithm allows you to do really cool stuff.

Huge and beyond

Designed for exabyte, current implementations in the multi-petabyte. HPC, Big Data, Cloud, raw storage.

…besides wicked-awesome?

What is Ceph?

Software All-in-1 CRUSH Scale

That WAS fast

Good together

OpenStack && Ceph

7

Come for the block Stay for the object and file

Cinders and Glances and …bears?

Reduced Overhead Easier to manage one cluster

“Other Stuff” Identity with Keystone, CephFS prototypes,

Gateway Drug

8

Squash Hotspots Multiple hosts = parallel workload

But what does that mean?

Instant Clones No time to boot for many images

Live migration Shared storage allows you to move instances between compute nodes transparently.

Blocks are delicious

9

Speak SWIFT Native support for SWIFT

And less filling!

Keystone Integration with identity

Horizontal Scaling Easy with HAProxy or others

Objects can juggle

Neat prototypes Image distribution to hypervisors

You can dress them up, but you can’t take them anywhere

Still early You can fix that!

Outside uses Great way to combine resources.

Files are tricksy

OBJECTS VIRTUAL DISKS FILES & DIRECTORIES

CEPH

FILE SYSTEM

A distributed, scale-out

filesystem with POSIX

semantics that provides

storage for a legacy and

modern applications

CEPH

GATEWAY

A powerful S3- and Swift-

compatible gateway that

brings the power of the

Ceph Object Store to

modern applications

CEPH

BLOCK DEVICE

A distributed virtual block

device that delivers high-

performance, cost-effective

storage for virtual machines

and legacy applications

CEPH OBJECT STORE

A reliable, easy to manage, next-generation distributed object

store that provides storage of unstructured data for applications

Where the metal meets the…software

Deploying this stuff

1

5

Procedural, Ruby

Written in Ruby, this is more of the dev-side of DevOps. Once you get past the learning curve it’s powerful though.

Model-driven

Aimed more at the sysadmin, this procedural tool has a very wide penetration (even on Windows!).

Agentless, whole stack

Using the built-in OpenSSH in your OS, this super easy tool goes further up the stack than most.

Fast, 0MQ

Using ZeroMQ this tool is designed for massive scale and fast, fast, fast. Unfortunately 0MQ has no built in encryption.

The new hotness

Orchestration

Chef Puppet Ansible Salt

6

Canonical Unleashed

Being language agnostic, this tool can completely encapsulate a service. Can also handle provisioning all the way down to hardware.

Dell has skin in the game

Complete operations platform that can dive all the way down to BIOS/RAID level.

Others are joining in

Custom provisioning and orchestration, just one example of how busy this corner of the market is.

Doing it w/o a tool

If you prefer not to use a tool, Ceph gives you an easy way to deploy your cluster by hand.

MOAR HOTNESS

All about RBD! CLI -> Librbd

No, not that one…

Nova Better boot support from Nova

Backups Including incremental backups for RBD

Havana

Live migration Improve Nova’s checks

Delightfully frosty

Bug Fixing New features from Havana

And you! The community does a lot to drive direction, we love input (especially when it looks like code)!

An ongoing process

While the first pass for disaster recovery is done, we want to get to built-in, world-wide replication.

Reception efficiency

Currently underway in the community!

Headed to dynamic

Can already do this in a static pool-based setup. Looking to get to a use-based migration.

Making it open-er

Been talking about it forever. The time is coming!

Hop on board!
