Folks,
I am sort of at my wit's end. I need to install Linux, preferably Ubuntu in my Dell R5500 Workstation which originally shipped with Windows7. With Ubuntu 12.02 LTS disc, I am basically going nowhere, I believe it is having trouble with GPU driver since right after the boot sequence start it goes to a blank screen and stay at that till I do hard reboot.
With CentOS 6.4, installation goes a little further with nomodest in boot option, but system run into loop initializing the raid array. We are using Perc 6 raid controller with raid10.
Here is my hardware setup.
2X Xeon, 128GB RAM, 2X C2075 Tesla GPU, Quadro 600 GPU
4X 900GB SAS drives connected to dell Perc 6 raid controller with one hotswap drive.
Please let me know if you have suggestions.

System works perfectly under Windows7, so I know the raid is in great shape.

I have no experience with almost ANY of that hardware, but did you look up to see if RHEL or 12.02 says they work with that RAID controller? While if it's not absolutely brand new I'd be surprised if RHEL didn't support it, I'd not be in the least bit shocked if there are no open source drivers that LTS didn't have it in, doubly so since the kernel in LTS isn't exactly a recent branch.

RHEL 6 64bit looks to support the Model Dell Precision R5500N: https://hardware.redhat.com/show.cgi?id=689538

Check the RAID controller here: https://hardware.redhat.com/

Also have you typed your Dell Service Tag into the dell site to see if anything by chance shows for Linux?

The Perc6 is a hardware controller and should work perfectly under Linux. What GPU does the server have?

Sorry to bump a thread that is so old now. I noticed yesterday that right after my dealings with Dell support, they quietly released a BIOS update late May 2013. So I installed the BIOS yesterday and VOILA. CentOS 6.5 now roaring.
