ISS Technology Update Volume 7, Number 6 To James and Kevin: Describe how Scott is an advocate for getting customer input into the design of HP products. Scott is eager to obtain customer information and input. Such input becomes an important design criteria when he architects and designs solutions to customer problems. Scott excels at considering all available aspects of design when he architects new features. He thoroughly considers customers' problems being solved by new features and how those customers will utilize those features. In addition, Scott does an unparalleled job of driving quality into his final solutions, delivering solutions that have few issues. An example of Scott's ability to consider customer input can be seen in his work on power management technologies. As power management and efficiency became important to customers, Scott worked diligently to understand our customers' issues and the technologies that could solve those issues. He strives to understand the customer's operating environment so that he can design solutions to meet their needs. Simultaneously, he ensures that HP does not invest resources in areas that would not address customer needs. Shut down servers gracefully with the HP ProLiant DL360 uninterruptible power supply solution Be prepared for brownouts and voltage fluctuations It is critical for servers to be able to shut down gracefully if a power supply brownout occurs or the input voltage varies beyond the range the equipment can accept. Any of these conditions pose serious threats to data integrity, potentially causing a loss of or corruption to a company's intellectual property and/or expensive equipment upon which it depends. To safeguard server and storage equipment against such threats, uninterruptible power supply (UPS) systems can be and should be installed. It is no longer enough to rely upon simple surge protectors in today's complex IT environments. How it works Basically, a high-quality UPS system⎯like the HP UPS R3000 shown in Figure 2-1 with an HP ProLiant DL360 Generation 5 (G5) server⎯will continually monitor the input sine wave within specified tolerances, watching for power anomalies to prevent complete power failure from occurring. Figure 2-1. Examples of rack-mountable UPS system and server HP UPS R3000 HP ProLiant DL360 G5 server series In the case of an anomaly, the UPS will attempt to adjust or switch over to batteries (using a built-in converter from DC to AC) until the input waveform is within specifications again. If management software is used in conjunction with the UPS, it sends the server a message to begin an orderly shutdown. Once back online, systems return to normal operation without interruption of power, and the battery automatically recharges itself. 5

To James and Kevin: Describe how Scott is an advocate for getting customer input into the design of HP products.
Scott is eager to obtain customer information and input. Such input becomes an important design criteria when he architects
and designs solutions to customer problems. Scott excels at considering all available aspects of design when he architects new
features. He thoroughly considers customers’ problems being solved by new features and how those customers will utilize those
features. In addition, Scott does an unparalleled job of driving quality into his final solutions, delivering solutions that have few
issues.
An example of Scott’s ability to consider customer input can be seen in his work on power management technologies. As
power management and efficiency became important to customers, Scott worked diligently to understand our customers’ issues
and the technologies that could solve those issues. He strives to understand the customer’s operating environment so that he can
design solutions to meet their needs. Simultaneously, he ensures that HP does not invest resources in areas that would not
address customer needs.
Shut down servers gracefully with the HP ProLiant DL360 uninterruptible power
supply solution
Be prepared for brownouts and voltage fluctuations
It is critical for servers to be able to shut down gracefully if a power supply brownout occurs or the input voltage varies beyond
the range the equipment can accept. Any of these conditions pose serious threats to data integrity, potentially causing a loss of
or corruption to a company’s intellectual property and/or expensive equipment upon which it depends.
To safeguard server and storage equipment against such threats, uninterruptible power supply (UPS) systems can be and should
be installed. It is no longer enough to rely upon simple surge protectors in today’s complex IT environments.
How it works
Basically, a high-quality UPS system
⎯
like the HP UPS R3000 shown in Figure 2-1 with an HP ProLiant DL360 Generation 5
(G5) server
⎯
will continually monitor the input sine wave within specified tolerances, watching for power anomalies to prevent
complete power failure from occurring.

until the input waveform is within specifications again. If management software is used in conjunction with the UPS, it sends the
server a message to begin an orderly shutdown. Once back online, systems return to normal operation without interruption of
power, and the battery automatically recharges itself.
