6. © 2001-2006 Cloudmark Inc. | 10160206-00 6 Architecture Transformed Current (With growth) SJC Master:8U (DL580 G5 + 2x HP MSA70’s) SJC:9U (DL580 G5, 2x DL380 G5, DL360 G5 + 2x 160GB FIO/ea) NJ:4U (2x DL380 G5 + 2x 160GB FIO/ea) SFO2:1U (1x DL360 G5 + 2x 160GB FIO/ea) Total:22U (more space used, but far more performance and system redundancy) Growth is supported without any loss in performance

7. © 2001-2006 Cloudmark Inc. | 10160206-00 7 Cloudmark wins Off the chart performance improvement 5x improvement in replication performance 5x improvement in data analysis performance Dramatic Foot-print reduction 31U of rack-space recovered 180 points of failure (drives) eliminated from the architecture Greatly reduced power and cooling expenses A double-edged sword that cuts the bottleneck from both sides Gain Performance Reduce Operational costs
