VMware ESXI 4.0 How to partition local scsi disk

I am new to ESXi 4.0.   I am trying to understand how to partition a datastore if that is possible or correct.
When I installed ESXi on my new Dell server it detected both RAID arrays and created two datastores.  One 130gig and one 850gig.  I want to split up that 850gig drive into two partitions.  
How do I go about doing that?  Do I do it in Windows Server 2003 when I install it, or does it need to be done before I install Server 2003?  
Thanks,

Firstly, there is no need to split up the 850gig partition. It is fine as it is, if I understand you correctly. VMFS partitions are designed to cope with large VMDK (virtual disk ) files.
So, when you build your Windows 2003 VM guest, you can assign to it as many hard drives as you want, so e.g. if you want a C (50GB) and D(100GB) drive, you can create two Virtual disks with those sizes.  You then can store those VMDKs on your 850gig drive. So your windows guest will never see the 850GB or 130GB disk on the physical server. It will only see what you configured.
If you still want to split your 850gig drive. You can do the following:
In the VI client, click on configuration -> Storage. Then right click your 850GB datastore and say delete. You can then create two new datastores if you want but I still wouldn't recommend it!
Hope this helps
