RED HAT CEPH STORAGE
OVERVIEW:RED HAT CEPH STORAGE
Powerful distributed storage for the cloud and beyond
OpenStack
Built from the ground up as a next-generation storage system, based on years of research and suitable for powering infrastructure platforms
TARGET USE CASES
● Cinder, Glance & Nova● Object storage for tenant apps
Object Storage for Applications● S3-compatible API
Highly tunable, extensible, and configurable
Offers mature interfaces for block and object storage for the enterprise
Customer Highlight: CiscoCisco uses Red Hat Ceph Storage to deliver storage for next-generation cloud services
TRADITIONAL STORAGEIS INFLEXIBLE
Using traditional, proprietary storage appliances:● Capacity is purchased one large appliance at a time
» Requires large investment, disruptive “forklift” upgrades
● Hardware is specialized and expensive» Cost and capacity do not scale evenly
Traditional storage appliances are not likelyto be deployed and managed by cloud builders
STORAGE APPLIANCE
COMPUTENODE
STORAGE SHOULD SCALEWITH COMPUTE
Using standard, readily-available servers:● Capacity can be purchased incrementally
» Saves money and increases efficiency
● One vendor can provide both storage and compute nodes» Increases purchasing power
Storage can be deployed by cloud builders● Instead of faraway storage admins in different departments

OPENSTACK
● Full integration with Nova, Cinder and Glance● Single storage for images and ephemeral and
persistent volumes● Copy-on-write provisioning● Swift-compatible object storage gateway● Full integration with Red Hat Enterprise Linux
OpenStack Platform
● Provides both volume storage and object storage for tenant applications
● Reduces provisioning time for new virtual machines
● No data transfer of images between storage and compute nodes required
● Unified installation experience with Red Hat Enterprise Linux OpenStack Platform
