Business and Technology Scenario
Continued economic uncertainty
Constrained/declining IT budgets though 2003
2003 net storage capacity growth of 60%-65%
10x growth by 2005/6 Hardware cost declines @
35% PA (55% in 2001) People do not get cheaper
Storage represents upwards of 15% of the IT budget, and 60%+ of the hardware budget
Hardware budget impact 8%, 1.6% of total IT budget

Uncontrolled storage growth will strain IT budgets. Leading ITOs will focus on “demand management”.

Matching Storage to Business Needs
Understand the business’ storage requirements
What services are important
Create a “portfolio” of storage services
Defined by SLAs Limit to 3-4 services Offer a range of cost/risks
Package people, process and technology into a service
Sell packaged services not raw technology
Optimise operations around these services/SLAs

Business Impact: A storage service portfolio makes cost explicit, enabling business units to choose
storage appropriate to their needs and understand the impact of this choice on their budget.
Creating a Storage Services Portfolio
Create a storage services portfolio that makes costs explicit in terms the business understands
Package people, process & technology into services
Create 3-5 services each with a SLA and unit cost Bill business units based on volume and unit cost
of the service they consume

Finding Meaningful Metrics
Question authority The ROI/TCO mandate
ROI is earnings/invested capital
What’s the revenue of disk drive?
What senior management really wants is payback
TCO relies heavily on forecasts and assumptions
Quantify efficiency, Question vendor claims

What’s the Target?
ROI and TCO require extensive assumptions, making them prone to self-fulfilling calculations

“Measuring” the Storage Infrastructure
If you are not keeping score you are just practicing
1. Storage per administrator 3.8TB benchmark Include B/R with disk
2. Data availability # of hours of annual
downtime (all causes)3. Mean time to recovery
Compare to application service levels
4. Latency to capacity agility Measured from
acquisition to application use

Compare to application service levels
4. Latency to capacity agility Measured from

5. Data life-cycle multiplier Number of times
specific data is copied6. % storage utilization
Used storage divided by total storage
Target 60%-85% Prioritize focus
7. Days storage in inventory How many days before
high-water threshold? Target 90-180 days

Develop Storage Procedures
List major areas of storage process
Provisioning and B/R are usually the largest
Analyse how these impact cost What are the cost drivers? How is efficiency affected?
Work on process with largest impact
Automate, Delegate & Eliminate to reduce cost

Business Impact: If the business is to be accountable for storage consumption, it has to know what it’s
consuming.
Measuring the Effectiveness of Storage Management Find meaningful metrics
Quantify what you can. Identify what you can’t. Qualify assumptions, while understanding ROI/TCO
limitations. Measure the storage infrastructure
Begin internal benchmarking to capture operational improvements
The goal is to measure internal operations as if it was a outsourcing deal

Virtualization means many different things to many vendors — scrutinize what business case it solves

Planning for Storage Virtualisation
Virtualisation defined Pooled, heterogeneous storage
managed as an single entity Logical access separate from
physical location Value is in storage apps, not the
virtualisation engine Engine moves to the fabric
(Brocade, Cisco) Who will write the apps for
these engines? Focus on delivering policy-based
storage through 2004/05 Event driven vs. process driven Increase storage administrator
efficiency

Business Impact: Virtualization promises to transform storage management from static to dynamic
Virtualising Storage
Understand the benefits (and costs) Don’t let the hype draw you in too early
Match vendor selection with strategic objective and requirements’
Virtualisation engines enable the applications Virtualisation's (empty?) promises
Although good in theory, it will be fraught with technical limitations, inhibiting large-scale deployments until 2004/05
