Virtual-to-physical Mapping The Storage

Groups to
facilitate different

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

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
IBM Storage Solutions © 2011 IBM Corporation8
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

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

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
