Achieving best performance for PowerEdge 2850, RAID0, partition, sector alignment, Windows 2008 Server

I have Poweredge 2850 with RAID 0.

Want to install Windows 2008 Server. Currently using Windows 2003 R2.
The problem is my current hard drive partition clustering and alignment which
is not optimized for database I/O performance.

The disk has 1 partition formatted with default 512 byte clusters and default alignment.

Windows 2003 uses the first 63 sectors for volume information before the start of the first partition,
causing the first partition to start on the last sector of the first track.

Typical database writes out data in 4,000 chunks so every eighth I/O will cross a track boundary,
resulting in additional latency on the I/O request. Using the DiskPart utility before formatting the drive,
the alignment can be set so that the first partition begins with a sector offset alignment of 64,
rather than the default 63, which causes the first partition to begin on a new track without incurring
any track overlapping.  

Now the question is - which steps Dell recommends in order to prepare the disk for Windows Server 2008
installation?

Thanks in advance
