I'd like to close this review with what I wish I'd done. I wish that:
- I had found a way to test software RAID to compare to hardware RAID and no RAID. I'm still worried about the step-by-step of repairing a software-managed RAID array. But, it would be interesting to see the speed hit. Especially across processors (Pentium, Centrino, x64 ...).
- I wish I'd tested XP Pro with the RAID5 hardware. I have done some informal testing, and it seemed like XP Pro did not have the large file performance hit that Linux has. It is time to go back and get the micrometer out an actually measure.
- I wish I'd known to test file system against write and read speeds on large files. That and, I wish I knew how to test file systems!
- I wish that I could get all the people posting to the Forumz from the first article to run iozone on their equipment and send me the equipment specifications (NAS and XP test system) and the .wks file that iozone creates.
Hope you enjoyed reading this as much as I enjoyed writing it!
Addendum: Making ISO CDs
ClarkConnect and Ubuntu 6.06 Desktop require you to download and then burn ISO CDs. Making an ISO CD is not hard. Here's how:
If you are on a Mac:
- Download the ISO image to your desktop.
- Open Disk Utility (/applications/utilities folder) then you can drag the ISO image from your desktop, and drop it on Disk Utility.
- Next, click on the ISO image in Disk Utility, and then click BURN on the Disk Utility toolbar.
- Follow the prompts, you are done. This ISO CD can be used to boot your x86 desktop computer and install Ubuntu and ClarkConnect software.
If you are using Windows XP:
- You can't burn an ISO CD with the stock software in XP. I'm sure there are other ways to do this, but I've always used Alex Feinman's excellent ISO Recorder to burn ISO CDs from Windows. Go to http://isorecorder.alexfeinman.com/isorecorder.htm and download the appropriate version of the software for your XP installation.
- Install the iso recorder software.
- Download the ISO images for ClarkConnect or Ubuntu to your desktop.
- After the ISO image finishes downloading, put a blank CDR in your optical disk drive.
- Finally, right-click the ISO image and then select burn from the popup menu. When the ISO is burned, you can use the CD to boot your computer and install software.
