  1. RSpecs for Storage Resources GEC 11RSpec July 27th, 2011 Michael Zink zink@ecs.umass.edu

  2. Motivation • DiCloud offers AWS S3 and EBS storage for GENI experimenters Orca DiCloud • Researcher creates a slice with: • weather radar • storage space on S3 • compute servers on EC2 ViSE Sensor Network S3 (storage) EC2 servers

  3. Getting started • What kind of storage will be offered in GENI? • One option: AWS S3 and EBS through DiCloud • Extend Orca with • Data-centric Slices: storage as a first-class resource with Amazon Simple Storage Service (S3) and Elastic Block Storage (EBS) • Cloud Computing: connect Amazon Elastic Compute Cloud (EC2) resources to GENI

  4. DiCloud Example • Obviously AWS S3 and EBS do not offer RSpecs • DiCloud can serve as an RSpec translator • Goal: Create RSpec V2 conformant resource description of available S3 and EBS storage resources. • Should also work for Eucalyptus clusters: • Eucalyptus’ Block Storage Service interface is compatible with EBS. • Walrus is interface compatible with S3.

  5. Proposal • Create RSpecs for S3 and EBS which are accessible via DiCloud as a starting point • Goal: • Keep it as general and extensible as possible • Provide working implementation in short-term future • Potential: • Storage RSpec could be adopted by other GENI cloud services • Could be prototype for storage in GENI racks • Available in Orca CF

  6. Example

  7. Example for Sensor Nodes

  8. Challenges What security model for storage in the cloud? How to share data with others? Storage leases can last years What if hard guarantees are required? E.g., user wants minimum I/O bandwidth for slice

  9. Future Plans • Discuss storage RSpecs for ProtoGENI • Discuss storage RSpecs for sensor networks • Coordinate with measurement RSpec activities • Start integration into RSpec V2 • Provide update at GEC12
