Benefits of Linux Open Networking & Software Defined Storage (SDS) for Cloud Environments Nolan Leake Co-Founder, Cumulus Networks nolan@cumulusnetworks.com Paul Speciale VP Product Management, Scality paul.speciale@scality.com

Agenda The New Data Center Challenges in the New Data Center Scale-out Storage based on Software-Defined Storage (SDS)  Key Capabilities of Open Networking Combined "Open Platforms": Synergies and advantages: SDS and Open Networking Flexible Deployment Topologies Management Frameworks Q & A / Discussion

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

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

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

Open Networking with Cumulus Linux Native Linux Operating Model Leverages native Linux OS and tools for networking Agent based monitoring & management Provides Full Network Functions Bridging, Routing, MLAGs, VLANs, IPv4/v6, Access Control, VXLAN and more Wide Choice of Open Network Platforms Choice from an ecosystem of large & specialized platform vendors Dell, HPE, Edge-Core, Quanta, Supermicro, Penguin and more

Open Platform Synergies: Flexible Topologies x86 Linux Scality RING Storage Spine Leaf Layer 3 Fabric Client A Client B 1.1.1.1/32 via swp1 1.1.1.1/32 via swp3 Spine Routing Table 1.1.1.1/32 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

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 x86 Linux Scality RING Storage (SDS)

Q & A / Discussion Open Platform Provides Key Advantages for Scale-Out Storage Clouds SDS is the new model of Distributed Storage with cloud economics Open Networking Provides key enablers in flexible network topologies Combined Solution Leverages Common Management & Automation Frameworks
