Hardware Admin Basics, What You Need to Know
What does it take to create a successful career for yourself as a system administrator? It all depends on who you ask. Some believe certification is key, some say experience, a few consider that it boils down to the tools used, and still others point to the value of sound academic training.We wrap up our server skill set series with a look at what you need to know to manage the hardware side of the server room.
When it comes to hardware, Wally Edmondson, a system administration for the University of Tennessee at Chattanooga, feels that the most important thing a solid background in computer architecture. Such a background enables him to deal with new technologies as they come along and diagnose problems quickly.
"Having at least a B.S. [bachelor of science] in computer science is a great start," says Edmondson. "I use the theories that I learned in my systems architecture concentration so often that they have become second nature."
But not everyone has the opportunity to spend several years at college. So bachelor of science or not, Edmondson advises budding sys admins to read as much as they can about new technologies, and think about how they work and how they are used. He also recommends finding a couple of hardware blogs of interest and reading them every day.
Are You Experienced?
Experience, of course, is that insurmountable barrier that potential employers throw up in front of you. So where do you start if you don't have any? Building a home server from parts is a straightforward way to learn about hardware. Although it is getting easier to do every year, building a server from the ground up still requires some searching and reading about the capabilities of each component, weighing price/performance data, selecting vendors, worrying about noise and heat, and troubleshooting startup problems basically resolving every issue a server room manager deals with on a daily basis.
With that accomplished, a next step might be to try building a cluster. Run it for a little while, then rebuild it using what you learned along the way.
Another tip is to focus on specific types of devices and obtain training from their manufacturers.
"Choose a brand like MSI, Amtron Technology, or Intel and go see the company to learn as much as possible," suggests Hamid Azar, a computer consultant from Sherman Oaks, Calif., who gained a wealth of experience working for many years as a system builder for Micron. "Choose one brand, learn all about it, and get trained by the manufacturer."
Azar is a registered Intel System Builder, for example. Whenever a new product appears, he is contacted for training, and that keeps him up to date. He's also received similar training and updating from motherboard and other manufacturers. This, he says, has proven invaluable when trying to figure out what's wrong. But why does the rookie generally take a long while to troubleshoot, and the veteran arrives at the heart of the matter in short order? Azar considers that there is no substitute for experience.
"80 percent of troubleshooting and resolving problems is experience," he says.
On that score, however, opinions differ.
"Some might say that experience trumps all, but things change too often in a data center for yesterday's fix or workaround to be relevant a year from now," counters Edmondson. "Knowing the theories behind the technology allows me to interpret my experiences with an eye towards fixing problems on a more permanent basis instead of the regular break-fix cycle."
Certification is another good way to get into the game. The Microsoft Certified Systems Engineer (MCSE) is the gold standard in the Windows world. Another highly regarded certification is the The CompTIA A+, which is an international industry credential that validates the knowledge of computer service technicians with the equivalent of 500 hours of hands-on experience.
"MCSE and CompTIA A+ are usually recommended for sys admins," said Pet Natividad, chief technology officer at Micro 2000, a Glendale, Calif.-based company that offers computer diagnostics software and certification courses.
Micro 2000's A+ course, for example, is a home study program designed to prepare the student for the CompTIA A+ exam. This course meets all of CompTIA's objectives and is a certified CACQ (Curriculum Authorized/CompTIA Quality) program.
But that diploma may be too costly for some future sys admins. For them, Micro 2000 offers an excellent beginning level PC Hardware Made Easy home study course. Unlike most computer courses that throw acronyms at the student and assume the reader is already familiar with key concepts, this one breaks everything down and explains it in simple terms.
"It takes the student through the very basics of computer hardware all the way through to the more advanced hardware technology," says Natividad.
Certification, or its various undercut home study courses, is a great starting point for many who wish to enter the sys admin realm. But it may not be the right path for everyone. Azar and Edmondson both got their feet wet via an insatiable desire to fool around with and fix computers. Edmondson, for example, got his start with a Commodore 64 several decades ago.
"Certification might get you in the door, but your attitude is what makes you indispensable," said Edmondson.
