  1. Reducing Risk with Cloud Storage

  2. Dells’ Definition of Cloud • Provision of information resources that are dynamically scalable and virtualized - as a highly available service. • Demand driven scalability: up or down, just happens • Metered: usage-based billing • Highly Automated: policy driven controls • minimal need for intervention • Robust: protects against systems failure • Virtual Resources: abstracted and pooled

  3. Assumptions and Definitions • Cloud Storage matters because it solves real business problems • Cloud Storage shifts storage cost from CAPEX to OPEX • Nice when both are reduced • Computing and Storage go together as Information Services are virtualized • Cloud Storage • demands effective resource planning • requires management • Can effectively use advanced services like: optimization, archiving, replication • Nice to have features of Cloud Storage • No capacity limits • No data loss or theft • No data corruption/degradation • No unplanned costs • No systems outages

  4. What is Dell DX Object Storage? Objectsare files stored as a single data stream together with content-rich metadata Namespace is flat & efficient using 128-bit UUID Metadata enables storage policies and data protection Dell DX Object Store is a Cloud Storage technology platform

  5. Measures of Risk Reduction DellDX Object Storage reduces storage risks: No Traditional file systems limits: Number of files, File Size, Naming semantics Reduced Data Loss: • No Obsolescence, Data protection, Improved security High Up Time: Management, Data Replication Avoid Unplanned Costs

  6. Dell DX Object Storage Value Points • Modular Design Flexibility • Add capacity as needed • Massively scalable • Node capacity in 4 or 12 drive units • 1, 2, 3, 4, 6, 12, or 24 TB nodes • Storage capacity easy to manage • Add, replace, retire through a simple console interface • Quick and automatic • No provisioning, No LUNs • Self-Managing • Storage policies • Cluster-wide default policy • Per object policy over-rides • Implemented as a background process • Compliance management • Driven by object header metadata • Capable of full background processing • Efficient Design • Intelligently stores data objects • Reliable storage • Peer scaling • Each storage node is an intelligent storage server • Designed Integrity Management • Self healing • Assures integrity of stored data • Built-in data replication facilities • Easy to deploy DR sites • Robust Infrastructure • Designed for rapid recovery from hardware and node failure without impacting cluster operation • Designed for to remain current • Easy to update to new generations • Seamless upgrade process

  7. Cloud Storage Protocol: HTTP • HTTP-based protocol • Open standard protocol enabling ubiquitous access • Basic HTTP methods • Create with POST (write) • Retrieve with GET (read) • Update with PUT (update any part of an immutable object) • Update with COPY (update object metadata) • Update with APPEND (update object with appended content on the end of the existing stream) • Retrieve metadata with HEAD (info) • Remove with DELETE (delete)

  8. Cloud Use Cases: For Verticals Media:Allow professionals as well as non-technical experts to quickly and efficiently produce new media-rich content, re-purpose existing content and distribute content through multiple channels, for consumption by users on multiple types of end devices.Telco:Enable large numbers of mobile end-users to safely access content on heterogeneous devices. Enhance the efficiency of content-rich applications by allowing fast adaptation to change in user context (e.g., location and device).Healthcare:Access healthcare data based on its content and its relationships, and automatically extract metadata from large volumes of medical data.Enterprise:Support multi-tenant cloud-native business applications, leveraging the advanced data model to provide database-like capabilities and efficiently migrate tenant data.

  9. Cloud Storage is shared! Multipletenants share the same Storage Cloud: What about security?

  10. Multi-Tenancy:Essential for Cloud Storage Secure infrastructure isolates data andthe consumption of system resources between tenants. • Storage Network Layer • Network separation - Zoning, VLANS • Data Storage Layer • Control storage access between tenants for security • Traditional techniques: LUN masking, SAN zoning • Physical partitioning of resources for quality of service • Examples: Assigning CPU’s, cache, disks, interfaces to VM’s • Private Cloud = shared resources is main concern (QoS) • Public Cloud = data isolation is main concern (Security) This is how …

  11. Dell DX Object Storage Multi-tenancy To enable a new tenant define a new Domain in the cluster: • Buckets: Users can create containers for named objects • Domains and Buckets have associated Security Realms containing authorization lists - list of users and credentials • Maintenance and administration of these Security Realms can be delegated to administrators who own a Domain • Individual Objects can have authorization lists attached as well DX Cloud Storage

  12. Intelligent Distribution Enabled by Metadata Dell DX Object Store Regional Data Center • Policy-based replication to geographically distributed site(s) • Policies driven by defined rules based on object metadata • Multiple replication and distribution topologies supported • 1:1, 1:M, M:1, M:M • Customize to meet specific needs • Replicate some or all files • Fully automated • Extensible for use in other post-process functions Affiliate Primary Site Metadata filter Object Routing Branch Office Disaster Recovery Site

  13. Traditional storage an obstacle? • The ability to leverage Cloud Storage when presently committed to traditional storage technologies can be a challenge. Issues include: • Vendor lock-in • Proprietary infrastructure • High retooling cost • Costs of retraining

  14. Dell DX Object Storage Migration Strategies Some ways to take advantage of Dell DX Object Storage technologies: • Write or modify applications to use HTTP directly • Change exiting softwarearchitecture to direct data I/O through middleware • Connector abstracts I/O implementation • Application becomes independent of the storage technology • Use of a Gateway solution • Use gateway to provide a “temporary” interface • Looks like a block-storage system to redirect data to DX Object Storage • Capture metadata separately • Also store in DX Object Store • Later migrate metadata to stored objects

  15. Conclusion • Dell DX Object Storage tangible Cloud Storage benefits: • Risk reduction • Consolidation • Improved information systems integration • Improved data manageability • Partnerships provide a broad solutions value to the Cloud Storage spectrum
