3. Open Software-Defined Storage is a fundamental
reimagining of how storage infrastructure works.
It provides substantial economic and operational
advantages, and it has quickly become ideally
suited for a growing number of use cases.

4. A RISING TIDE
“By 2020, between 70-80% of unstructured data will be held on
lower-cost storage managed by SDS environments.”
“By 2019, 70% of existing storage array products
will also be available as software only versions”
“By 2016, server-based storage solutions will lower
storage hardware costs by 50% or more.”

10. MGMT
All required dependencies are now included within a local package
repository, allowing deployment to non-Internet-connected storage nodes.
MGMTCORECORECOREOBJECT
Administrators can now perform basic cluster administration tasks
through Calamari, the Ceph visual interface.
Erasure-coded storage back-ends are now available, providing durability
with lower capacity requirements than traditional, replicated back-ends.
A cache tier pool can now be designated as a writeback or read cache for
an underlying storage pool in order to provide cost-effective performance.
Clients can be configured to read objects from the closest replica,
increasing performance and reducing network strain.
The Ceph Object Gateway now supports and enforces quotas
for users and buckets.

These features were introduced in version 1.2 of Red Hat Ceph Storage,
and have been supported by Red Hat since July, 2014.

Core Themes
Robustness at Scale
Operational Efficiency
Performance

17. Red Hat Ceph Storage 1.3 contains improved logic and
algorithms that allow it to do the “right thing” for users with
multi-petabyte clusters where hardware failure is normal:
ROBUSTNESS AT SCALE
Improved self-management for large clusters
● Improved automatic rebalancing logic, which prioritizes
degraded over misplaced objects
● Rebalancing operations can be temporarily disabled so they
don’t impact performance
● Time-scheduled scrubbing, to avoid disruption during peak
times
● Sharding of object buckets to avoid hot-spots

18. Ceph is a distributed system with lots of moving parts.
Red Hat Ceph Storage 1.3 introduces features to help
manage storage more efficiently.
OPERATIONAL EFFICIENCY
Making administration tasks easier
● Calamari now supports multiple users and clusters
● CRUSH management via Calamari API allows
programmatic adjustment of placement policies
● Lightweight, embedded Civetweb server eases
deployment of the Ceph Object Gateway
● Faster Ceph Block Device operations make resize,
delete, and flatten operations quicker, while export
parallelism makes backups faster

19. CEPH WITH SANDISK INFINIFLASH

20. A number of performance tweaks improve the speed of
Red Hat Ceph Storage 1.3 and increase I/O consistency:
PERFORMANCE
Speedier, more efficient distributed storage
● Optimizations for flash storage devices
increases Ceph’s topline speed
● Read ahead caching accelerates virtual
machine booting in OpenStack
● Allocation hinting reduces XFS fragmentation
to avoid performance degradation over time
● Caching hinting preserves the cache’s
advantages and improves performance
