2. hIOmon Overview (9/01) © 2001 hyperI/O LLC. 2 More about hIOmon Looking for answers – how hIOmon can help Presentation Outline So whats the problem?

3. hIOmon Overview (9/01) © 2001 hyperI/O LLC. 3 More Productivity More Information More Profit More Time Benefits of Improved Performance: So how do you gain better performance? Better Performance Focus upon Performance

4. hIOmon Overview (9/01) © 2001 hyperI/O LLC. 4 Faster: processors (>1GHz, SMP, x-Way) busses (PCI-X, InfiniBand) Faster computer hardware But how much performance have you actually gained? - and whats the actual Return-On-Investment (ROI)? (Moores Law: 2x every 18 months) NAS, SAN, DAFS, iSCSI Storage I/O connections: Storage I/O interfaces: SCSI, FC, 10GbE, VIA Computer hardware keeps getting Faster

5. hIOmon Overview (9/01) © 2001 hyperI/O LLC. 5 Storage capacity deployed How do you get and manage better storage performance, especially with more and more storage capacity? Individual storage device capacity keeps doubling (even faster than Moores Law) Storage device capacity Digital data growth: 45-60+% / year >50% capital investment Managing the storage costs more than the storage itself Storage is a major component of computer systems The explosive growth of Storage

6. hIOmon Overview (9/01) © 2001 hyperI/O LLC. 6 There is an enormous gulf between the performance capabilities of the faster computer hardware (particularly processors) and … the performance capabilities of storage:A Performance Predicament Waiting, waiting, waiting … for your Data

7. hIOmon Overview (9/01) © 2001 hyperI/O LLC. 7 Computer hardware keeps getting faster And the amount of storage keeps growing So how much performance: - have you actually gained? - and whats the bottom line ROI? But storage performance has not kept pace Better performance is important (many benefits to be gained) Problem Summary
