collected into

Groups to

The Storage

Controller

“insulates” the host

systems from the

effects of changes

in the physical

environment so disk

subystems can be

moved in and out

and copy services

can span dissimilar

subsystems

Storwize V7000 storage virtualization principles


Benefits of External Storage Virtualization

View all storage as one virtualized storage pool, independent of physical location

Ability to consolidate and integrate 3rd party storage systems into one multitiered storage architecture

Exploit the advanced storage software with all externally attached storage systems

Common management and business continuity software

– Any-to-any replication between all attached systems

Add the enterprise storage capabilities to other midrange modular or legacy storage systems


Thin Provisioning


Without thin provisioning,

pre-allocated space is

reserved whether the

application uses it or not. It

is static

With thin provisioning,

applications can grow

dynamically, but only

consume space they are

actually using.

Dynamic

growth

• More productive use of available storage.

• Improve storage utilization

• Decrease CAPEX and OPEX

Thick versus Thin Capacity Provisioning

What is Page Zeroing?

• “Fat” to “Thin” migration• Unused pages to return physical storage to Thin provisioning

pool• Decreases the capital expenses

The I/O Monitor captures access patterns

and generates usage statistics sending them

to the Data Placement Advisor

The Data Placement Advisor identifies hot

spots and outputs potential data migrations to

the Data Migration Planner

The Data Migration Planner performs

analysis to deliver recommended data

migration plan to the Data Migrator based on

the physical storage characteristics

Data Migrator confirms and schedules data

migration activity based on the data migration

plan using SVC function to seamlessly

relocate the data to higher performing storage

without any application interruption

A “hot spot” is formed on a magnetic disk

when an application makes frequent use of

the same area or extent of a volume

Advanced Solution Options with Storwize V7000


IBM Storwize V7000 Value and Summary

Very compact packaging: controllers and disk in just 2U– Half to one-third rack space required by EMC CLARiiON CX4-240

Completely new GUI based on well-received XIV GUI– Provision a volume in as few as six clicks; setup system in as few as ten clicks

– Proven to be very easy even for novice users in UCD tests

Enterprise-class capability– Sophisticated local and remote mirroring

– Integrated server and storage management

High performance in a midrange disk system– Up to almost 1M IOPS

– Up to 82,000 IOPS for “database-like” 70/30 R/W workload

Integrated non disruptive migration function– Speeds time-to-value from weeks or months to just days

– Minimizes downtime for migration

– Eliminates cost of add-on migration tools

Integrated no-charge Easy Tier function– Application throughput improved up to 200%, up to 30% improved response time

Integrated no-charge thin provisioning function– Reduce disk capacity required by 20% or more; reduce disk capacity for copies by 75% or more

Similar benefits to SVC when virtualizing external storage
