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

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
SHORT TERM: PRICE/SUPPLY DISRUPTION

?
PRICE PER CAPACITY OVER TIME
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
THE END OF A 50 YEAR TREND?

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
WHAT IS CAPACITY EFFICIENCY?
![Page 8: Capacity Efficiency: Identifying the Right Solutions for the Right Challenge](https://reader036.fdocuments.us/reader036/viewer/2022070317/5562fe7ed8b42a62598b4dbe/html5/thumbnails/8.jpg)

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)
A UNIVERSE OF TECHNOLOGY OPTIONS

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
STORAGE VIRTUALIZATION – THE FOUNDATION FOR CAPACITY EFFICIENCY
![Page 10: Capacity Efficiency: Identifying the Right Solutions for the Right Challenge](https://reader036.fdocuments.us/reader036/viewer/2022070317/5562fe7ed8b42a62598b4dbe/html5/thumbnails/10.jpg)

STORAGE VIRTUALIZATION – THE FOUNDATION FOR CAPACITY EFFICIENCY
It is cheaper to virtualize and reclaim than to buy net new capacity
![Page 11: Capacity Efficiency: Identifying the Right Solutions for the Right Challenge](https://reader036.fdocuments.us/reader036/viewer/2022070317/5562fe7ed8b42a62598b4dbe/html5/thumbnails/11.jpg)

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

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

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 Operational excellence Consumption behaviors
Use TCO to measure and compare
ROI and ROA to cost-justify
4 key principles of storage and IT economics
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

Lower CAPEX Reclaimed capacity Longer asset usefulness Lower cost of growth with overall
utilization improvements
Cost of migration Labor, tools, outage, ROA 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
DIRECT COST REDUCTION BENEFITS OF STORAGE VIRTUALIZATION
Software maintenance costs
Hardware maintenance costs Support rates commensurate with the tier
of data Older assets can be demoted to lower
tiers, different maintenance rates
Management, labor
It can be significantly cheaper for you to virtualize and reclaim, than to purchase new capacity

“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
