RED HAT CEPH STORAGE 2 THEMES
USABILITY OBJECT IMPROVEMENTS PERFORMANCE

13
USABILITY: RED HAT STORAGE CONSOLE
An easy to use interface for
managing cluster lifecycles
•  Ansible-based deployment tools
for driving granular conﬁguration
options from CLI or GUI
•  Monitoring and graphs for
troubleshooting with statistical
information about components

14
OBJECT STORAGE IMPROVEMENTS
Global object storage clusters
with a single namespace
•  Enables deployment of clusters
across multiple geographic
locations
•  Clusters synchronize, allowing
users to read from or write to
the closest one
•  Ideal for follow-the-sun, CDN or
Disaster Recovery
STORAGE CLUSTER

STORAGE CLUSTER
US-WEST

15
OBJECT STORAGE IMPROVEMENTS
Support for authentication using
Active Directory, LDAP & OpenStack
Keystone v3
Greater compatibility with the Amazon
S3 and OpenStack Swift object storage
APIs
•  AWS v4 signatures, object
versioning, bulk deletes
New NFS gateway for import and
export of object data (tech preview)

16
PERFORMANCE: BLUESTORE (TECH PREVIEW)
BlueStore is a new Ceph storage
backend optimized for modern media
•  Replaces FileStore, which was designed
for HDDs
•  Supports flexible media topologies (flash,
K/V drives, persistent memory)
•  Eliminates the need for an underlying
filesystem or dedicated journal device
•  Provides a 2-3X performance boost

17
OPENSTACK: RBD MIRRORING
Multi-site replication for block
devices (RBD Mirroring)
•  Replicates virtual block devices
across regions
•  Designed for disaster recovery
and archival
•  Integration with Cinder Volume
Replication (OSP-10)

OPENSTACK: CEPHFS (TECH PREVIEW)
CephFS is a POSIX-compliant ﬁle system for use with OpenStack Manila
•  Support for FUSE or kernel clients (RHEL 7.2)
•  Approach: robustness, hardening, then scalability
