hings I Wish I Knew When Becomming A Linux Admin
Ten years ago I installed Linux for the very first time. To be exact, it was Slackware 7, the best distribution at the time in my opinion. Since then I’ve come to favor Debian Linux as my favorite version…at least for my Linux servers. I like to have a solid core system installed that I can build from scratch, but this is for another time. This article is for you new Linux admins; here are the ten things I wish I knew when starting my Linux admin journey.

From parallel SCSI to serial SCSI
SCSI (Small Computer System Interface), often called Parallel SCSI, is almost 30 years old and can hardly keep up with the demands of today’s IT environment. Serial Attached SCSI (SAS) was developed to address the limitations inherent in SCSI. This article highlights the differences between these two interfaces and points out the attributes that account for the increasing popularity of SAS.
Scale your file system with Parallel NFS
The Network File System (NFS) is inadequate for the demanding input- and output-intensive applications commonly found in high-performance computing—or, at least it was. The newest revision of the NFS standard includes Parallel NFS (pNFS), a parallelized implementation of file sharing that multiplies transfer rates by orders of magnitude. Here's a primer.

Burning CDs Over the Network with webCDwriter
Most home and small offices really don't need more than one CD burner. Even many large companies only need one, or maybe two. Yet it only takes a few frustrating episodes to convince you that a few extra burners would be a good idea, especially if one of them was in your machine. Before you run out to purchase this new equipment, consider taking an older machine and setting it up by itself, with no other purpose than to be a CD burner.
