ISS Technology Update Volume 8, Number 7
Meet the Expert—Alan Goodrum
Alan Goodrum is a Fellow with HP Industry Standard Servers (ISS). His career with
HP actually began in 1985 with Compaq and over the last several years, his
primary focus has been power management both in servers and the data center as
a whole. Today, power management is arguably the “hotest” area of the server
industry, but it hasn’t always been. Dwight Barron, Alan’s manager says, “Alan
started working on power efficiency of servers long before it was recognized as
one of the most critical problems to be solved by the computer industry.” Power
efficiency appears to be a perfect venue for Alan’s skills because “he understands
and solves problems by simultaneously working at multiple levels of abstraction
and detail,” according to Dwight.
A solid foundation
Alan’s experience has taught him that the spiritual aspects of life are the most
important. Most of his activities outside of work revolve around his church. He
teaches a weekly adult Bible study class and visits nursing homes around the
Tomball area as part of a group of volunteers. Several years ago, he discovered

that residents of nursing homes appreciate a smile, a kind word, and a prayer. He

also discovered that “once you have a solid foundation based on who you are
Servers
and where you want to go, all the other things just seem to fit into place.”

engineer. He liked the challenge of understanding the tools of mathematicians and
scientists and then applying those tools to build things that actually work.
His favorite accomplishments
Alan’s favorite accomplishment to date is Dynamic Power Capping. Several years ago, he was on the team that conceived the
technical possibility of allowing system administrators to manage server power consumption. Dynamic Power Capping controls
the maximum power that a server can consume, allowing administrators to fit more servers into the same power and cooling
space. The goal of Dynamic Power Capping is not to save energy but to provide predictability in server power consumption.
Predictability allows for better planning, which can delay enormously expensive data center expansions. Alan helped with early
testing of the power capping concept; nurtured it through a complex joint development process with Intel; drove the detailed
functional specifications; and finally saw it launched as a key Thermal Logic Technology in ProLiant G6 servers.
Alan had a similar sense of satisfaction during the development of the PCI-X bus. PCI-X extended the bandwidth of the popular
PCI bus to 133 MT/s (megatransfers per second) and later to 266 MT/s. The concept was first proposed by some key ASIC
designers at Compaq. And although other companies had proposed abandoning the PCI bus, a coalition of Compaq, HP, and
IBM eventually took the idea to the PCI SIG. Alan chaired the committee that published the specification. Eventually, Compaq
servers were the first to market with PCI-X slots. Alan noted that for several years a major competitor used our PCI-X ASIC inside
their servers but had to put a heatsink on top of it to cover up the Compaq logo.
He has a strong customer focus
Alan believes that customer input is critical, but finding the right solution can be difficult because often, customers can describe
only their problems, not the solutions. He says that the key is to talk to enough customers to be able to anticipate the kinds of
solutions they will find useful. Dwight believes that Alan’s strength resides in understanding the business constraints that
customers face in adopting new solutions and then helping them work through those issues.
