3. Challenges in the New Data Center
Software Defined Data Center (SDDC) enables long-term flexibility based on cloud models & expertise of the Internet Giants
OpenStack, Applications, Workloads, Infrastructure, Management, and Scale impact the new data center
Cloud environments will provision 100’s – 1000’s of VMs, with disparate, expansive & growing storage requirements for image, file & object data
Massive application data requirements: 100’s of Terabytes of documents, Petabye-scale archives, rich media repositories
This drives a need for large-scale distributed storage solutions for the Cloud
OpenStack Swift & Amazon S3 are the leading APIs for object storage in the cloud
Creates an increase in complexity for network topology and infrastructure management
Can be simplified by an open platform based on standard software for storage and networking

4. Scale-Out Storage Architectures based on SDS
Distributed Storage is now the normal model for the cloud
Multiple object & file storage services (“Connectors” in the Scality model)
Scale-out capacity enabled by distributed storage nodes
SDS provides key advantages
Intelligent storage services: data durability at scale, self-healing & growth w/o disruption
Flexible platforms & cloud economics from choice of large & specialized vendors
Frequent advancements in software functionality
Management automation via standard frameworks
API based monitoring & management

5. Data Placement Considerations in Distributed Storage
Failure Domains
Distributed data protection schemes include replication (multiple object copies) or Erasure Coding chunks (variable parity schemas)
Data chunks should be separated across disks, servers & racks
Data Proximity
Protocol Servers -> Storage Nodes
For performance, we’d like data to be within a small number of network hops D D D D

Scale-out for performance & capacity
Load balancing & failover across Connectors and Storage Nodes via Anycast and ECMP
Separation of failure domains (racks & servers) through distribution of storage
Maintains proximity of compute to storage for performance

8. Open Platform Synergies: Management Frameworks
Common Management Automation Frameworks
Simplification: both open networking & SDS managed by the same frameworks
Choice of Puppet, Chef, Ansible, Saltstack, and more both storage & network configuration management automation
Leverage Standard Tools from wide range of platforms & vendors
Cumulus Open Networking & Scality SDS support from standard tools
Integrates into popular OpenStack or other cloud environments
