Network appliances help ease major changes to the system

Traditional values

Blade servers may be cutting into the market for traditional servers, but there are still many applications where rack or tower servers are an appropriate and sensible choice. While traditional servers and blade servers perform the same tasks, the main differences are in expandability and processing density.

Blade servers: Cutting edge

The market for blade servers is growing rapidly, especially for new installations, but also for those replacing older server farms. What's surprising is not that blades are soaring in popularity, but why it took so long.

Power User: Still seeking common sense, the Power User logs off

I've spent years in Washington and elsewhere and have concluded that lack of common sense is by far the greatest threat facing this country.

An unprotected PC or server connected to the Internet has about 65,500 open ports. That translates into thousands of possible points of attack for hackers.

Power User: Record what you want, where you want

For the second Power User column in a row, I actually have some new products to talk about. This is unusual for me because these days I seldom see anything new and worthwhile.

Enterprise storage - it's SAN-tastic

Whether you're part of a large agency that has long dealt with massive storage requirements, or a smaller agency just beginning to buckle under the weight of accumulated data, the storage area network'in all its increasingly varied flavors'remains a popular solution

Cybersecurity

Don't be put off by PKI

Implementing a public-key infrastructure is a daunting task. It is a very expensive and complex project, in which many components have to be tightly integrated with an existing network.

Power User: Hardware that works: A truly portable scanner

Sometimes I like to use this space to talk about a new product that's crossed my desk. So here's one for you.

Cybersecurity

Spy vs. anti-spyware

The question is simple.

Power user: For agencies, it's Firefox no, OpenOffice yes

Several weeks ago, I wrote a somewhat lukewarm review of Firefox that got a big response from defenders of the open-source Web browser.

Power user: Avoiding the Longhorn stampede starts now

Power users are always checking out operating systems still in development.

Cybersecurity

Lines of defense

The last year or so has seen unprecedented consolidation in the IT security field'especially in the antivirus business, where big companies, including Microsoft Corp., have gobbled up innovative small companies.
