The Best Storage VirtualizationPlatform on the Planet that your

Competitors will die for

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

• Technology changes faster than capitalization rate

• Utilization of storage is still fairly low - 30%

• Many companies are approaching the knee of the growth curve

Capacity Growth Rate

A refresh cycle follows 3 to 5 years behind

Outdated Storage: 20 Year Old Architectures

• Expensive High Function Monolithic Storage

• Lower Cost, lower 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

What Happened to the Promise of SAN?

• SAN promised consolidation through the elimination of islands of storage

• Ten Years later the utilization of storage is still about 20% to 30%

What happened?• SAN Networked servers to storage but left the

islands of storage• Storage systems are not networked to work

together • Storage systems are still provisioned

separately• There is no data mobility between storage

systems

Control Unit Virtualization:The key Enabler

• Only 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> Provides data mobility that is

transparent to the application

Volume Migration in a ST9900/ST9985

• Volume Migration is done in the controller cache

• Data that has not been moved yetcan be accessed from the S-Vol cache image

• Information in the control store keepstrack of where the data resides.

• No impact to the SAN switches or to the host

• Provides non-disruptive migration between multi tiers of storage

Dynamic 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

Gartner – Thin Provisioning is Revolutionary

"Thin provisioning coupled with virtualized back-end disks improves staff productivity by simplifying storage provisioning and eliminating most tuning activities associated with solving performance problems."

Different Approaches to Storage Virtualization

“SAN’s are the third leading cause of application failures, with an average outage of 25.5 hours” Disaster-Resource.com 2006

All Storage Controllers Do Virtualization Today

• Host servers talk to cache images of disks in a storage controller - not to the actual physical disk

• Storage Controllers create a Logical Unit Number (LUN) from a Redundant Array of Independent Disks (RAID)

• Controllers have years of proven data mobility functions like snap copies, remote replication, Copy on Write

• The storage control unit is the best platform for virtualization of external storage

> Because it has all the information needed to virtualize storage

Why Don’t Other Storage Vendors Do the Same?

No other Storage Controller has a Dynamic Cache Architecture

• Dynamic cache enables changing storage configurations without disruption to applications

• Virtual ports enable physical ports to support thousands of host connections

• Host Storage Domains provides each virtual port with it own address space for safe multi-tenancy

• Logical Partitioning insures QoS for critical applications by partitioning resources like cache

• Switch architecture insures availability by switching around failures and hot spots

The Evolution of Hitachi/SUN Storage Virtualization

Global Cache with separation of control and data

Introduction of first scalable crossbar switch architecture

Introduction of Virtual Storage Ports and Host Storage Domains with second generation of crossbar switch architecture

Introduction of Storage Area Management and heterogeneous (external) storage management

Cross-System Copy is introduced to move data between Lightning V and Thunder V without host intervention

ST9900 enables large-scale virtualization of externally attached storage behind third generation crossbar switch architecture

The Storage Industry: The Future View

• A Virtual storage infrastructure to match dynamic business growth • Consolidation of management through one common interface without

vendor lock-in• Add storage as business requires without giving up functionality or

over buying • Extend the life of current assets and enable easy technology upgrades• Dynamically move data to the appropriate tier of storage as required.
