| Seven Simple Steps

|
| 1. Think green
| |
| | 6. Investigate liquid cooling
|
| Environmental concerns are front of mind

| | To meet the challenges of blade servers

| | 7. Utilize greener energy sources
|
| by legislation, standards and market
| |
| | Many energy utilities are now offering
|
| demands in this area.

| | greener options for customers, with power

| 2. Virtualise and consolidate
