2. Data center operations evolving Continuous modulation Incremental adjustments Over-provisioned (Hours) (Days) (Months) Dynamically adjust capacity based on continuous input Energy Savings Waste … But HIGH margin for error Optimize demand and reduce the peaks by distributing computing load more evenly Still the problem of high peak demand Today Tomorrow Yesterday MODIUS – CONFIDENTIAL 2

3. Changing environment Macrolevel trends Evolving servertechnology Green regulation & green initiatives Rising electricity costs & limited supply • Increasingly dynamic power and heat loads • Decreasing over-provisioning (cooling) • Growing use of virtualization (CPU) • Power save features in CPUs Data centerevolution • Blade & other high density devices • Adds / Moves / Changes • Rising operational challenges • Smaller margins for error / less time to react • Greater risk of unanticipated capacity failure • Current tools not designed to manage dynamic environment Impact Need • New tools for greater visibility, early warning, & historical analysis MODIUS – CONFIDENTIAL 3
