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

9. The Traditional Storage Models No Longer Work
4/17/2017
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

10. The Archaic View of Monolithic Storage
4/17/2017
The Archaic View of Monolithic Storage
What is a typical high-end storage system comprised of?
Cheap, Commodity Media (HDDs)
Control Unit
High technology central control unit encapsulated with cheap media
To recover control unit R&D costs, more and more disks are needed
Ever larger disk systems become more difficult to provision and refresh
This growth model is not sustainable !

11. The Archaic View of Modular Storage
4/17/2017
The Archaic View of Modular Storage
What is a Modular Storage System composed of?
Low cost, Active/ Passive, Dual Controllers
This architecture is designed to serve the few with great efficiency
Connectivity is Limited – 2 or 4 ports per controller
Availability is limited – Maintenance windows are required for controller failures, upgrades and configuration changes
Data mobility functions are limited and disruptive
Must be done during non production windows
Limitations are not viable in a 24/7, real time business

32. Efficient utilization of storage is Green Storage
4/17/2017
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

Questions/Discussion

34. 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
