The Dynamics of Storage Growth

• Storage growth rate is compounding

• Regulations and disaster recovery drive longer retention, with redundant copies

• Transaction access rates growing faster than capacity for operational data

• Utilization of storage continues to be less than 30%

• Technology changes faster than capitalization rate

• Whatever you install today will be replaced in 3 to 5 years

Technology refresh becomes more disruptive as capacity grows

Meanwhile, The Business EnvironmentIs Changing

• Opportunities – Mergers, acquisitions, consolidation – Global expansion – “The world is flat” – New services and technology enablers– Cross selling and up selling

• Exposures– Operational risk

• Threat of wide-scale disasters, Global Warming, over runs, terrorism

– Regulations and Corporate Governance• Tighter controls, audits, transparency

– Economic uncertainty• Rising interest rates, Rising energy Costs

• IT Constantly Must Align and Adapt to Changing Business Challenges

The ratio of Management to hardware costs are2:1 to 4:1 or more

As a result the Cost of IT is not tracking to Revenue


The Traditional Storage Models No Longer Work

• Expensive High Function Monolithic Storage

• Lower Cost, low function, Modular Storage

• 20-year-old architectures that were designed for:– Direct attached storage – No sharing– Two Shift Operations – Maintenance widows– GBs of Capacity – Easy to manage and migrate

Hitachi Storage Control Unit Based Virtualization:The Key Enabler for Services Oriented Storage

• Hitachi storage controller based virtualization:

– Provides common storage and data services for all heterogeneous storage and application requirements

– Adds no complexity or latency

– Is not limited to SAN connection

– Preserves end-to-end security

– Enables seamless integration of future capabilities

Hitachi Thin Provisioning Software

• Optimize Storage Capacity by provisioning only what is used

• Optimize Storage performance by spreading the I/O across more arms

• Simplify Management by allocating what is asked for and automatically provisioning only what is used

• Simplify performance tuning by spreading the I/O across all the disks in the Pool

Summary

• Storage growth continues to accelerate while utilization remains a challenge.

• Storage arrays built on 20 year old architectures can not meet today’s dynamic requirements

• New Storage Requirements Need to be addressed as services – not with box solutions

• Services Oriented Storage simplifies storage infrastructure, reduces risk, and reduces cost with common services that can be leveraged across all storage assets

• Efficient utilization of storage is Green Storage

• The Dynamic Data Center of the future will be based on services orientation, SOA, SOI, SOS


Technology

• Servers and Operating Systems – 2011 and beyond

– Predictions are that by 2013 a Supercomputer will be built that exceeds the computational capabilities of the human brain

– By 2023, it will take a $1000 computer to exceed the capabilities of the human brain

– …and while prediction beyond this are difficult to estimate, 15 years later in 2049 a $1000 computer will exceed the computational capabilities of the entire human race

– Digital Information will exceed the available capacity of storage
