vmware vmx parameters

Hi

I am installing a 2 node 10gR2 RAC in my labtop using vmware. I have come
across some doubts

Setup:
-------------------------------------------
Host OS: Windows XP PRO SP2
Guest OS: CentOS 4.2
VMWare Workstations 5.0

I am using a external USB Drive for all this setup, both Virtual Machines
and the shared storage.

I have questions regarding vmware parameters, to start with does anyone know
what does these paraneters do? (I understand they are used for Shared
Storage). The best list I have found is here:
http://dev.remotenetworktechnology.com/vmware/vmxfiles.htm

diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
scsi1.present = "TRUE"
scsi1.sharedBus = "virtual"
scsi1.virtualDev = "lsilogic"

I cant find anything in Vmware documentation which explains about these
parameters. Since I am going to use them I would like to know at least what
am I doing :-)

Regards

LSC
