De-fragging is the equivalent to dusting as a housekeeping chore. What it does is rearrange the "furniture" such that a sequential read of a file can be done optimally. How often...
I use such raids extensively on servers. My present POE has raids on all servers, and personally I have set up two raids for important personal stuff. Most os stored on both, and they are in different servers on two different locations.
They tend to run hot, and the leading edge drives have a tendency to fail quite early.
That said, the optimum price point has moved from 120GB to 200 GB drives since summer. The cheaper, 2nd generation 200GB drives are upon us.
Two of those raid disks that have been swapped out are now 200GB disks where only 120GB is actually used in a raid. I may change out the last 3 soon, before they fail by themselves, and build another logical volume on those 80G chunks.
What I am doing now is insert cheap 80G disks in all desktop boxes as well. Raids everywhere. I am even looking at having a raid in my laptop. Would require changning out the DVD, but it may be worth it.
I am moving towards PXE boot. I already have it set up for OpenBSD, and that was as easy as they come. Fedora is next. Plug in box, boot etc. May do some dedicated scripting in that case.
It is all backed up on those raids via NFS anyway, so it just has to be exported back.
We cannot possible backup directly to tape with current technology. We must go through storage hoops over a VPN. It is an exercise in making Amanda do stoopid pet tricks.
Fast, reliable, cheap (OK, I know, pick two) tape jukeboxes would be an alternative.
I have the fortunate fate to work a place where Windows boxes are explicitly not a priority. The owners are responsible for those.
We DO have to support Linux servers though. In that respect, 2.6 is a whole new OS to relate to. Linux has grown up.
How versatile was this configuration base? Let me ask this in a different way. How did you evaluate a system that had non-IBM gear and-or connections to it? As sophisticated as that benchmark...
