Nexenta Storage in the Cloud

Andy BennettDirector Field Operations EMEA

Cloud Storage

Requirements and Market Trends

Storage Trends

• Storage virtualization– Abstracting physical attributes helps commoditize

the storage

• Commodity components replacing specialized hardware for data storage

• Global economic downturn putting pressure on capital and energy costs– Motivation to by newer, more energy-efficient

hardware

Exponential Data Growth

• New use cases and types of data– Unstructured data– Machine-generated files to be processed by other applications– Video streaming– Video surveillance

• Regulatory requirements for protecting and retaining data• Reliance on data as competitive advantage

“More data will be stored in the next three years than in the previous 40,000”- Berkeley’s School of Management (2010)

NAS Market: Compound annual growth rate of over 50% for capacity – IDC 2011

Cloud Storage

Use Cases• Storage for cloud applications• File replication of critical data for disaster recovery• Off-site backup for power and floorspace benefits in the

datacenter• Geographically dispersed teams that need to write to

centralized storage for long-term data access• Long-term deep data archives

What is it? Storage accessed over the Internet and purchased based on usage

Key Requirements

• Priced competitively• Flexible• Scalable• Elastic• Easy to manage• Optimized for virtual environments

Requirement: Competitive Price

• Cloud vendors must offer a low $/GB to users to be competitive

• Baseline set by Amazon Web Services and Amazon Simple Storage Service (S3)

Free 5GB S3 storage for first year! Free 5GB S3 storage for first year!

$0.14/GB per month or less$0.14/GB per month or less

Requirement: Flexible

• Cloud storage is new and optimal protocol choices are not agreed upon

What's the best storage protocolto use with VMware? NFS? iSCSI?What's the best storage protocolto use with VMware? NFS? iSCSI?

Should I replicate the data? How?Should I replicate the data? How?

Should high availability be handledby the application or the storage

layer?

Should high availability be handledby the application or the storage

layer?

Requirement: Scalable

• Is architecture designed to support tens of petabytes?

• Predictable linear performance improvements expected as storage is added

• As easy to manage 1 system as n

Requirement: Elastic

• Shrink and grow capacity dynamically to align with user needs

• Customers want to pay only for what they use

Requirement: Manageable

• Integrate easily with the cloud vendor's management portal

• REST and SOAP APIs preferred

Requirement: VM-optimized

• Virtualization being heavily used in cloud deployments

• Make efficient use of physical resources• Virtualization can offer isolation for multi-

tenancy

Competitively Priced

• NexentaStor runs on commodity x86 servers– Gives customer more control over hardware component choices

• Customers own perpetual licenses– Hardware refresh can proceed without any additional payment to Nexenta– Refresh of legacy storage is often more expensive than the initial purchase

• Reduce effective price through storage efficiency:– instantaneous snapshots– compression– de-duplication– thin provisioning– hybrid storage pools– reservations– quotas (including user and group quotas)

16

Flexible

• Unified storage appliance– NAS + SAN

• Supports key protocols– CIFS, NFS, iSCSI, FCOE, FC WebDAV

• APIs and Web GUI to easily reconfigure

Designed to scale

• Multi-core support• SSD support• “No limits”

18

“just add hardware – and it accelerates”

Increased chance of silent data corruption as you scale.NexentaStor can detect and correct the corruption.
