1 Storage Requirements for the Public and Private Cloud Siamak Nazari Principal Engineer September 2009

2 Agenda What is Cloud Computing Public versus Private Cloud Storage Requirements for the Private Cloud Case Study 1

3 3PAR: Leading Provider to the Enterprise Cloud Magic Quadrant for North American Hosting 8 of the 11 Leading Cloud Service Providers Choose 3PAR 2

4 Utility Computing drives new requirements Mainframe Computing Shared Virtualized Inflexible Expensive Distributed Computing Utility Computing Shared Virtualized Agile Lowest Cost Multi-tenant infrastructures Service Providers & Internal Service Bureaus Do More With Less Handle diverse/unpredictable Lowest TCO Dedicated Physical 1:1 Flexible Lower Cost Internal Virtualization Automation Clustering 3

5 Utility Computing enables New Service Delivery Models Enterprise IT as a Utility Service Cloud Computing Software as a Service (SaaS) Managed Hosting (HaaS), Web 2.0 Internet Internet Virtual Data Centers Private Cloud Internal Service Bureaus delivering to Depts, LoBs Intranet Utility Computing Utility Storage Server Virtualization Blade Servers Virtualization Automation Clustering 4

6 Distinguishing Attributes Traditional Data Center Public Cloud Utility Data Center or Private Cloud Acquisition Model Develop architecture and buy assets Buy service Develop architecture and buy assets Business Model Pay for fixed assets, recruit/maintain skilled workforce Pay based on use Asset purchases aligned with use, unburden workforce Access Model Internal network Internet Internal network Technical Model Single tenant, non-shared, static Scalable, dynamic, multitenant Scalable, dynamic, multitenant Source: Traditional, Cloud Computing Attributes from Gartner (September 2008) 5

7 Needs are Similar Between Public, Private Clouds Public Cloud AGILE Quickly adapt to the unpredictable to improve book-to-bill EFFICIENT Lower TCO and align costs with revenue SECURE Eliminate compromises associated with shared infrastructure Private Cloud AGILE Rapidly adapt to the unpredictable to improve project ROI EFFICIENT Lower TCO and align costs with IT/business goals SECURE Eliminate compromises associated with shared infrastructure 6

8 Agile: Adapt to the Unpredictable, Improve Project ROI Address unplanned demand Grow massively, non-disruptively Eliminate impediments to business growth Accelerate time to provision new or changing workloads Rapid, autonomic provisioning in seconds without pre-planning Dynamic optimization across storage tiers Remove storage from the critical path 7

9 Efficient: Lower TCO, Align Costs with Business Goals Purchase capacity only as needed for new application data Start and grow in small increments Reduce capacity and energy costs by up to 75% Thin provisioning, thin copy to eliminate allocated, unused capacity Fast RAID 5 to reduce RAID capacity overhead Reduce administration time Reduce administration time Rapid, autonomic provisioning in by up to 90% seconds without pre-planning One-time provisioning without up-front purchases 8

10 Secure: Eliminate the compromises of sharing assets Secure dedicated assets with shared cost structure Hypervisor-like technologies for storage to create secure virtual arrays within a single physical array Eliminate security as an objection to a shared array Assure service levels Full, automatic load balancing to maintain robust performance Mix workloads without service level impacts Carrier-class availability Deliver high and stable QoS for all workloads 9

11 Utility Storage: Ideal for Private Cloud Deployments Agile Grow massively, non-disruptively Rapid provisioning Dynamic optimization across storage tiers Efficient Start and grow in small increments Thin provisioning, thin copy Fast RAID 5 Rapid provisioning Secure Hypervisor-like technologies for storage Full, automatic load balancing Mixed workload support Carrier-class availability A highly-virtualized, tightly-clustered and dynamically tiered storage array 10

12 Major Usi US Storage Cloud Service History Provider Storage History Agility functionality? Stability performance

13 Major US Cloud Service Provider USi Storage: Present Storage Present 200 TB 2009 = PBs 200 TB 200 TB

14 Major US Cloud SP Architecture Model 20 new customers / week Benefits Agile - VM-based apps like SAP, Oracle, Peoplesoft - Dynamic optimization to manage SLAs Efficient - Thin provisioned - Snaps for daily backups - RAID 5 (7+1) - Cost effective DR Secure - Shared - Multi-tier FC & SATA - Committed SLAs 13
