Next generation storage deployment:

6. Seagate Confidential 6
Ceph Deployment
Object Storage Daemons (OSDs):
• 10s to 10000s of OSDs in a cluster
• One per disk or SSD
• Serves stored objects to clients
• Intelligently peers to perform replication
and recovery tasks
• Support for erasure encoding of objects
• Support for strong consistency leveraging
write journals

Advanced Storage:
• Shingled Magnetic Recording (SMR)
Drives (drive managed)
• Excellent density, cost, read performance,
and sequential write streaming.
• Poor random write performance.
• PCIe Flash
• Excellent performance, in server integration
• Poor cost per GB.

7. Seagate Confidential 7
Featuring:
 Nytro XP6302 flash accelerator
card
 Nytro XD—tuned caching SW
 12x 8TB SMR HDDs
Benefits
 Accelerate Ceph journals and Metadata
with flash
 By moving this data onto flash, cost-
effective SMR drives are well-suited
for extremely dense object storage systems
reducing storage costs by 25%.
Nearly triples Ceph object storage performance
