Sales by business segment and global market

2008 Total: EUR 2.8 Billion

Vision │ A leading water chemistry company

Target customers

Focus on customers operating in water-intensive industries

Water quality and quantity management

Water use, reuse, recycling, and recovery

Bringing value to customers’ processes

Improvement of energy, water, and raw material efficiency

Combining understanding of industrial processes and customer needs with a sustainable product portfolio and application expertise

Water footprint is becoming more important

A product’s water footprint consists of the total use of water in its value chain. For instance, the water footprint of beer also includes the water needed to grow barley. For industrial products, the water footprint is evaluated against the product's value – on average, 80 l / dollar. Source: www.waterfootprint.org

Decreasing the water footprint will be even more important with the increasing water shortage

Paper

10 l of water for a

sheet of A4 paper

Beer

75 l of water for a glass of beer

Leather

16,000 l

of water / kg

Industrial products

8 million l of water per

vehicle (value: $100,000)

Synchronous mirroring between local arrays: Recover image, but susceptible to logical corruption

Any Point-in-Time Recovery

Traditional recovery methods

Nightly backups, snapshots, mirrored images plagued by time gaps, corruption

RecoverPoint

Recovery to any point in time– Mount image to any host in SAN– Full read/write access to image

without protection loss

Use recovered image for a variety of purposes– Operational recovery– Backup, testing, or decision support– Reporting

Grouping for a Consistent View

Allows application recovery to be tiered by service level

• Multiple volumes per group• Mixed recovery point objectives

within same infrastructure

Provides independent replication controls

• Recover by group, locally or remotely

• Start/stop by group

Enables grouping of optimization • Importance• Resource usage• Recovery point and recovery time
