I have a dell disk array that is a few years old as well as a pci-x scsi card. I would like to put pci-x scsi card in my dell r805. The dell r805 only has 4 pci express slots and no pci-x slots. I have searched all over google and have not found out the answer. Will the pci-x card work in the pci express slot in my r805?

You must have skipped the first page of google results. en.wikipedia.org/wiki/PCI-X –  Ben M Jan 20 '10 at 19:15

I don't know where you got that link from Dan but right now it's giving a 404. –  John Gardeniers Jan 20 '10 at 21:38

No it won't work, they're physically and electrically incompatible. Let us know what model of disk array you have and we'll try to find you something that will work.

It is a dell powervault 220s. –  eodchop Jan 20 '10 at 20:34
I bought an LSI pci express card. It works wonderfully. Thank you for your help! –  eodchop Feb 8 '10 at 0:12

No it will not, PCI-X and PCI-E are very different hardware devices. Definitely not compatible.
