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?
Objects are 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
Dell DX 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

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
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!
Multiple tenants share the same Storage Cloud: What about security?

10. Multi-Tenancy: Essential for Cloud Storage
Secure infrastructure isolates data and the 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
DX Cloud Storage
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

12. Intelligent Distribution Enabled by Metadata
Disaster Recovery
Site
Affiliate
Branch Office
Regional Data Center
Metadata filter
Object Routing
Primary
Dell DX Object Store
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

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 software architecture 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. Dell DX Object Storage tangible Cloud Storage benefits:
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
