Never purchase under time pressure

Use a dual-supplier policy wherever feasible

Don’t allow a vendor to bypass the technical staff

Align the deal time with the vendor’s timings and sales incentive programs

Don’t show enthusiasm

Always obtain line-item pricing

Lean toward purchase rather than standard lease if upgrades or extension are planned

Destroy the self-confidence of the sales representative

Residual Value vs. Technological Life

The annual price erosion will continue with at least 30-50 percent The cost are shifting into storage features and storage management. Current product cycles are 18 to 24 months Maintenance becomes prohibitively expensive after two cycles Products more than two cycles old are economically obsolete Upgrades are uneconomical after one cycle if the warranty

is not extended

Consolidated Disk Storage

SAN, NAS or High-End Enterprise Larger investment in procurement, but

Better use of “spare capacity,” flexible LUN sizes with dynamic reconfiguration

Improved availability, performance, security and disaster recovery

Ability to consolidate and automate backups, tape libraries

Multi-platform data transfer and new file systems

More efficient access, sharing and distribution of information throughout the enterprise

Lower storage management costs

Hosted by

When to Acquire? Big Steps or Small?What to consider

• Price erosion

• Vendor upgrade granularity

• Software band’s granularity

• Operation disruptions

• Faster utilization of spare capacity

• RFP overhead

• Contract administration overhead

New Financing Models

Standard lease• Subsystem storage costs are spread equally

over the lifecycle of the lease (flat rate).

• Match situation when storage requirements are not growing or grows by new lease or purchase of additional subsystems

Pay per forecast • This model is designed for users with constant,

continuous and predictable growth rates.

• Instead of paying flat leasing rates up front, the monthly lease payments are made according to the usesage forecast

Hosted by

New Financing Models (cont’d)

Capacity on demand or pay per use — This “utility” model is best suited for users with unpredictable storage demands.

Emerging metering metering applications extract usage data at regular intervals from the customer’s storage devices. Usage data is averaged and the customer receives a monthly bill based on average usage.

Capacity-on-demand considerations• Speed of activation• Dynamic activation?• Coverage of temporary peak demands.

• Challenges to overcome

• Variable cost vs. static budget

• Tracking peaks

• Measurement rationale

Hosted by

Storage Management Costs

Up to 1– 4 ratio between cost of capacity and cost of storage management (most of costs are labor costs)

Required manpower to manage• Distributed storage: 500GB/manager

• Central location but not consolidated: 600GB/mgr. to 800GB/mgr.

• Multiplatform consolidated storage: 2,000GB/mgr. to 4,000GB/mgr.

Future • Increase in personal costs

• Data capacity explosion

Storage Network InfrastructureThe Fibre Channel SAN component market

continues to consolidate dramatically; will new switch vendors finally reverse the trend?

iSCSI tentatively explores a complementary market and waits for the “10 Gbps” performance kick

Native InfiniBand storage is generally off the map for storage networking

Vendors of competing technologies (falsely) blame economic factors for slow market progress

The 10-Gbps convergence will likely be a no-show

Hosted by

Ask the server providers, not the storage systemOEM customers

Increasing SAN awareness on part of servers

Switching support of 4-Gbps connections for servers

10-Gbps connections for storage systems

Existing standards-based backward compatibility

Favorable incremental costs of connecting a server to a SAN

Technology upgrade without price premium

Implementation in low-cost copper

Better match to available buses in 2004

Why 4-Gbps FC Infrastructure?

Hosted by

IP versus Fibre Channel Scenarios

The market for iSCSI and IP block storage

will evolve as a complement to FC in the

market where lower cost and enhanced

connectivity is paramount (0.7 probability)

Competition for next-generation SAN

infrastructure will play out on a level playing

field with a common 10-Gbps physical layer

for both Ethernet and Fibre Channel (0.3

probability)

• Storage is a peripheral to the server

• Much manual administration

• Poor asset utilization

• External high availability, fault-tolerant storage

• Some sharing, but mostly DAS

• Much manual administration

• Poor asset utilization

• More productive storage administration

• Storage networks, pools, virtualization, event consoles, some automated provisioning

• Separately managed processes, services, devices and media

• Autonomic active management

• Policy-based management• Full-scope automated

RecommendationsBuy storage, not visions

Negotiate everything and get creative

Deploy ATA-based systems carefully

Plan for Fibre Channel to remain the dominant high-performance technology for SANs from 2 to 10 Gbps

Choose FC link extenders and SAN extenderswith careful consideration of requirements

Plan for IP storage technology to provide lower-costand extended-connectivity solutions

Continue to view all SAN management and ASAM purchases as tactical
