Ubuntu on Dell PowerEdge 2850

[Patrik Lermon]

My company are looking for a server to host a web service, and we have
been considering the Dell PowerEdge 2850 with:

- 2 x 64-bit Intel Xeon processor 3.0GHz with 2MB L2 cache and
- Integrated PERC4e/Di RAID Controller (RAID5)

We would like to run Ubuntu on it, but we would also accept pure Debian.

I have a couple of questions:

1. Does Ubuntu run on multiple 64-bit Intel Xeon processors, as standard?

1 a. If it does, are we supposed to use the amd64 distribution, even
though we are using Intel Xeon preocessors?

1 b. What processors does the amd64 distribution run on?

2. Are all packages that are available in the x86 architecture also
available in the distribution we are supposed to use?

3. Does Ubuntu support Dells integrated SCSI controller: PERC4e ?
