The Need for Storage Optimization
• In 2000 10 TB was considered a large storage environment
• Today it is common to have 100s of TBsand PBs
• What will happen in the next 10 years• Capital budgets no longer support p g g pp
endless storage purchases• Power, cooling and floor space is limited, g p• People resources find it hard to manage
all of this infrastructure
Market Dynamics• 70% to 90% of data is never used 90 days
after its creation• Lots of copies of data including drafts• Capacity utilization rates are low often in p y
the 30% range• Storage optimization can result in
i ifi i h d d f significant cost savings – hundreds of thousands to millions

Thin Provisioning
• Just-in-Time Capacity • Provision what you anticipate but only • Provision what you anticipate but only
consume what is needed• Shared storage pool to allocate physical
capacity as neededp y• Create thresholds and alerts
d d d l• Provide reports and trending analysis
Thin Provisioning in the Real World• Most storage systems support some form of thin • Most storage systems support some form of thin
provisioning• Thousands of users are using thin provisioning• Thousands of users are using thin provisioning• Many are using it with mission-critical applications
C i ft f 30% tili ti t 70% • Companies often go from 30% utilization to 70% +• Companies that use thin provisioning regard it as a
i it i f drequisite going forward• However many users still believe there’s a risk• We are unaware of any user reporting a major or
sustainable issue with thin provisioning
Intelligent Tiering• Sub-Volume and Volume Tiering• The ability to move data to different
l fclasses of storage• Classes can include RAID levels and
d ff ddifferent drive types – SSD to SATA• Transparent demotion and promotion• Policy-based and automated• In-the-box tieringe bo e g• External tiering• Thin Provisioning DR VDI Dedupe• Thin Provisioning, DR, VDI, Dedupe
Sub-Volume Tiering• Volume tiering has limited value• If 10% of a volume is active and the
h h h lother 90% is inactive then that volume is still regarded as “active”
b l k f• Sub-volume keeps active portion of volume on Tier 1 and moves inactive portions to lower tiersportions to lower tiers
• Tiering includes disk drives but also RAID levelslevels
• Tiering is not archiving – you can move primary data to and from tiers primary data to and from tiers immediately as needed
Tiering in the Real World• Today Compellent and 3PAR have sub• Today Compellent and 3PAR have sub-
volume tiering• Compellent is the leader and has the most • Compellent is the leader and has the most
granular solution• EMC and HDS projected to have this later • EMC and HDS projected to have this later
this year• Others will follow• Others will follow• The impact could truly be significant –
Compellent claims up to 80% reduction in Compellent claims up to 80% reduction in cost over time
• At some point – we will have no choice to • At some point – we will have no choice to implement intelligent tiering
Writable Snapshots• The ability to create volumes making • The ability to create volumes making
logical copies of primary volumes that are writable writable
• New writes are the only thing that consume more capacityconsume more capacity
• Great for test and development environmentsenvironments
• users can make a large number of copies without impacting capacitywithout impacting capacity
Storage Virtualization• The ability to manage third party storage • The ability to manage third-party storage
from an external storage controller• Leverage the intelligence of a high end • Leverage the intelligence of a high-end
storage system to manage less intelligent devicesdevices
• Functions such as thin provisioning and replicationreplication
• One user was able to reclaim $3M in allocated but unused capacityallocated but unused capacity
• Vendors include HDS, IBM and NetApp
Storage Virtualization in the Real World• Over ten thousand users doing this today• Over ten thousand users doing this today• users have saved millions of dollars
implementingimplementing• Sub-LUN tiering should raise the value

deployed storage virtualization and then deployed storage virtualization and then changed their minds
• Some users still see the risk – who • Some users still see the risk – who supports what?
MAID• Spin down drives so they reduce power • Spin down drives so they reduce power
and cooling while increasing MTBF• Not widely deployed• Not widely deployed• Part of the issue includes performance and
reliability concernsreliability concerns• Spin down will make more sense with sub-
LUN tiering – it could be the “killer app”LUN tiering – it could be the killer app
Data Compression• Some primary storage systems are adopting • Some primary storage systems are adopting
data compression• Can support lossless compression without Can support lossless compression without
rehydration reaching 2:1 and even 4:1• Data compression will add latency during the p y g
compression process but depending on the architecture could be minimalDell q i ed O in nd IBM q i ed • Dell acquired Ocarina and IBM acquired Storwize
• Startup Nimble Storage supports compression • Startup Nimble Storage supports compression natively
• EMC announce compression for CLARiiON and EMC announce compression for CLARiiON and Celerra storage systems
Data Deduplication• Adopted in D2D Backup but not for • Adopted in D2D Backup but not for
primary storage• We are on our way to PB environments • We are on our way to PB environments

primary but the solutions are limited• Other solutions are coming – BlueArc • Other solutions are coming – BlueArc
announced this capability• Primary dedupe is very effective within • Primary dedupe is very effective within
VMware environments• Dedupe and compression are • Dedupe and compression are
complementary technologies
Making Primary Dedupe Work • Moore’s Law • Moore s Law • Intelligent and efficient indexing
P li i f i li d t • Policies for in-line and post process• Tiering• Eliminate rehydration
File Management and Optimization
• Files are quickly becoming the majority of the capacity consumed
b l h l f d• No visibility with lots of unused, unimportant and duplicate files stored on Tier One storageTier One storage
• IT is not allowed to delete user dataWh i i d i di • What is required is a way to discover, auto-classify, optimize and migrate files heterogeneouslyheterogeneously
File Management in the Real World
• One of the biggest challenges in the data center going forward
l ll h f f l d d• users literally have PBs of file data and their only course of action is getting more NAS systemsNAS systems
• This challenge requires scale, intelligence and the tools to analyze and act on the and the tools to analyze and act on the problem
The Cloud?• Are we past the hype?• Are we past the hype?• Using the public cloud as a lower tier
requires better understanding of the costsrequires better understanding of the costs• There are appliances that will provide
connectivity to the cloud automaticallyconnectivity to the cloud automatically• Consider the reduced floor space, power
and coolingand cooling• users are getting some aggressive pricing
from cloud vendorsfrom cloud vendors• Applications in the cloud is where much of
the focus is – changing the IT model above the focus is – changing the IT model above the infrastructure layer
