The document discusses the challenges of aging IT systems and the disruptions caused by limited HDD availability, emphasizing the need for increased capacity efficiency. It highlights strategies such as storage virtualization, capacity reclamation, and improved utilization to address both short-term and long-term issues. The overall goal is to reduce costs and improve ROI through effective storage management and economic principles.
Capacity Efficiency: Identifying the Right Solutions for the Right Challenge
- 1. HITACHI DATA SYSTEMS: CAPACITY EFFICIENCY SNW Spring 2012
- 3. LONG TERM : ITS A CHALLENGING ROAD AHEAD Aging IT systems and infrastructures Increasing burden to maintain Switching to new systems and infrastructure becomes more disruptive and resource-intensive Information becomes increasingly difficult to access and analyze Business is forced to work without the information it needs to make decisions New interfaces drive up transaction loads and require legacy storage systems to scale up Storage systems are long-term investments and changes are increasingly painful and expensive Compliance and regulatory pressures puts businesses with legacy systems at risk Power, cooling, and floor space limitations demand change
- 4. SHORT TERM: PRICE/SUPPLY DISRUPTION Unprecedented geological event caused worldwide disk shortage, resulting in Limited availability and increased price of HDD Compromised growth and business disruption Forecasting challenges Missed sales and revenue targets Shortage may persist into 2013, creating immediate need for increased capacity efficiency worldwide via Increased storage utilization Capacity purchase deferral Capacity reclamation Extension of useful life of existing assets
- 5. THE END OF A 50 YEAR TREND? PRICE PER CAPACITY OVER TIME 1950 3Q 2011 If the price decline in disk capacity slows down: Need to eliminate redundancies and wasteful practices Need to increase the efficiency of capacity utilization Need to Increase the capitalization from 3-5 year to 5-7 years and separate storage intelligence from storage capacity
- 7. WHAT IS CAPACITY EFFICIENCY? The RIGHT solution for the RIGHT storage challenge – at the RIGHT point in the data’s lifecycle Allocation: Thin provisioning Utilization : Storage tiering Performance: Page level tiering Data Protection: Active archive Energy: SSD and SFF Management : One platform for all data Application: VAAI Extend these benefits to existing storage assets with virtualization
- 8. A UNIVERSE OF TECHNOLOGY OPTIONS REDUCE NEED, RECLAIM EXISTING CAPACITY AND DEFER PURCHASES Storage pooling and thin provisioning Virtualization Tiered storage and dynamic tiering Disk configuration optimization − RAID 5 and 6 vs. RAID 10; high vs. low density Storage reclamation: ZPR and write same Thin replication Copy-on-write Service catalogs and chargeback information Intelligent archiving (compression, deduplication and single instancing)
- 9. STORAGE VIRTUALIZATION – THE FOUNDATION FOR CAPACITY EFFICIENCY Increase storage utilization Use more of existing and new assets – up to 30% Reclaim capacity and defer purchases Reclaim high performance capacity for future use – up to 50% Extend useful life of existing assets Non-disruptive migration allows for reduced tech refresh period, extending use of systems Repurpose existing assets Manage heterogeneous storage capacity as a single pool that inherits the benefits of the parent array Simplify IT infrastructure Common management Extend cost savings features to existing storage systems, not just new ones
- 10. STORAGE VIRTUALIZATION – THE FOUNDATION FOR CAPACITY EFFICIENCY It is cheaper to virtualize and reclaim than to buy net new capacity
- 11. VIRTUALIZATION IMPACT ON COSTS Heterogeneous storage pools ‒ Single point of management ‒ Consolidation of software licenses and maintenance fees ‒ Subordinate arrays inherit control system features and functions • Thin provisioning, dynamic tiers, VAAI Extend the useful life of assets – sweat the storage assets ‒ Virtualized assets can be demoted as they age and kept in the virtual pool ‒ Maintenance contracts can become creative to meet SLA and overall costs ‒ Environmental costs will, over time, determine cost inefficiencies of older arrays in the pool Capacity reclamation ‒ 20-30% space reclamation is not uncommon with virtualization alone ‒ Coupled with thin provisioning, reclamation of 50% is very common ‒ With large consolidations and virtualization initiatives • Reclaimed capacity can be used for organic growth and CAPEX avoidance • Capacity consolidation reduces number of frames on the floor
- 12. VIRTUALIZATION IMPACT ON COSTS Array migration, data migration ‒ Migration costs tend to be $7-15K per TB with monolithic architectures and can take several months to complete ‒ Virtualized storage migration is nondisruptive and can be completed in a few weekends at a fraction of the previous cost Advanced storage functionality ‒ SAN and NAS converged ‒ Multitenancy ‒ Chargeback, metering, policy-based management Virtualization can enable new storage architecture capabilities ‒ Dynamic tiers, and flexibility with data types (structured, unstructured, rich media, file, block, etc.) ‒ Virtual volumes and capacity on demand ‒ Content depot to share a common storage infrastructure ‒ Cloud services that include multitenancy, metering and billing ‒ Scale up, out and deep ‒ VM impact for scaling, performance and overall costs

HDS STORAGE ECONOMICS The application of economic and financial principles to storage It is becoming increasingly necessary to apply economic and financial principles to IT Architectures, roadmaps, standards Identify Operational excellence Consumption behaviors Measure Use TCO to measure and compare Reduce ROI and ROA to cost-justify 4 key principles of storage and IT economics Measure Again Price does not equal cost – price is about 20% of TCO 34 different types of cost – where is your sensitivity? There are economically superior IT architectures Econometrics – you cannot improve what you cannot measure

- 16. DIRECT COST REDUCTION BENEFITS OF STORAGE VIRTUALIZATION Lower CAPEX Software maintenance costs Reclaimed capacity Longer asset usefulness Hardware maintenance costs Lower cost of growth with overall Support rates commensurate with the tier utilization improvements of data Older assets can be demoted to lower Cost of migration tiers, different maintenance rates Labor, tools, outage, ROA Management, labor Migrations tend to be 10-20% of the cost and overall time required with virtualization Cost of software licenses Common pool, one source for control, replication It can be significantly cheaper for you to virtualize and reclaim, than to purchase new capacity

THE PROOF IS WITH OUR CUSTOMERS “With Hitachi virtualization technologies, we've seen storage capacity savings of 50% on some arrays, now provision storage in 25% of the time, and have increased utilization rates by over 30%. Overall, we've reduced our capital and operating costs for an improved return on our storage investment.” − Carter Lee Vice President of IT Operations, Overstock.com
