Reducing Risk with Cloud Storage

Dells’ Definition of Cloud

• 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

Provision of information resources that are dynamically scalable and virtualized - as a highly available service.

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

What is Dell DX Object Storage? Objects are files stored as a

single data stream together with content-rich metadataNamespace is flat & efficient using 128-bit UUIDMetadata enables storage policies and data protectionDell DX Object Store is a Cloud Storage technology platform

No Traditional file systems limits:

Number of files, File Size, Naming semantics

Measures of Risk Reduction

Dell DX Object Storage reduces storage risks:

High Up Time:Management,Data Replication

Avoid Unplanned

Costs

Reduced Data Loss:No Obsolescence,Data protection, Improved security

• 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

• 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

Cloud Storage Protocol: HTTP

• HTTP-based protocol

• Open standard protocol enabling ubiquitous access

Basic HTTP methodsCreate 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)

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.

Cloud Storage is shared!

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

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 …

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

Intelligent Distribution Enabled by Metadata

• 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

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

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
