Well, I will admit to my taste being typically more along the expensive side
of things, but a fast, robust, multitasking, multi-user UNIX-style
operating system like GNU/Linux actually deserves true SCSI storage. ;-)

The machine I'm setting up Xen and Gentoo on has an Adaptec 32105 SAS RAID
PCIe controller, with 4 Hitachi UltraStar 147 GB 15k SAS disks, which is a
reliable and fast solution. ;-)

As a sidenote regarding that machine, when I installed the Xen hypervisor
and Xen tools, it took less time for Portage to fetch the sources - I did
an "emerge --sync" first - and then compile them and install them than I am
used to seeing via .rpm-based utilities on binary distributions.

I guess the Source is with me, Obi-Wan.
