For anyone else googling trying to find the answer to this, as I was today, I refer you to the following Red Hat article:
To paraphrase, the solution is to take the RAID card out the server and throw it in the bin. The S300 isn’t a real RAID card, it’s a fakeraid. You’re better off just using Linux software RAID.
Unfortunately, the cabling in the server doesn’t allow for connecting to the on-board SATA ports, or rather for powering them. Speaking to Dell support, they initially suggested that just disabling the card in the BIOS would be sufficient; they later admitted it isn’t, and offered to send out suitable cables.
I seem to remember Dell making a big deal of their entire server line offering full Linux support some time ago, so I’m surprised to see them making this retrograde step – particularly as Linux represents a large percentage of the server market. In Dell’s defence they do make it reasonably clear that the S300 card isn’t supported under Linux at the ordering stage.

For obvious reasons everyone is looking to make cost savings at the moment, and for inspiration you can look to the French Gendarmerie, who have saved millions of Euros as part of a transition to Linux.
“A report published by the European Commission’s Open Source Observatory provides some details from a recent presentation given by Gendarmerie Lieutenant-Colonel Xavier Guimard, who says that the Gendarmerie has been able to reduced its annual IT budget by 70 percent without having to reduce its capabilities.”
Read the full story over at Ars Technica.
One often overlooked issue with regards to calculating the total cost of ownership for an OS: power consumption.
These figures from http://mjg59.livejournal.com/103511.html:
- Idle power draw of Fedora 10: 100W
- Idle power draw of Opensolaris 2008-11: 135W
A bit late to the party with this one, as he started whilst I was on holiday, but Linux create Linus Torvalds has started his own blog.
It’s interestingly entitled ‘Torvalds Family Blog’, although Linus being Linus I’m sure we’ll see some excellent highly controversial non-family posts, just like his mailing list postings.
Some of you may have heard about the kerfuffle surrounding poor Perl performance on Red Hat 5/CentOS 5 – it got a bit of attention on reddit/digg. Red Hat had been issuing hot fixes to people who complained, but now Karanbir Singh has created an updated Perl package.
This issue should be fixed in RHEL/CentOS 5.3, but until then, if you’re experiencing slowness I’d advise installing this – after appropriate testing on staging/UAT servers of course.
