You need to configure 32bit Oracle for PAE and AWE extensions in order to address more memory than what the default Win32 memory manager allows. But are these extensions not only applicable to a Win32 kernel? Does a Win64 kernel supports memory extensions for Win32 virtual machines running in it?
Keep every thing as is except change the OS from 32 bit to 64 bit so that the memory can increase upto 32 G, its a big change will give us some time.
Two new servers (which we have) Install RAC, Oracle same version, use Grid and no ASM.Not using ASM would be a mistake. Yesterday I moved a production database (RAC) from an old SAN to a new SAN. Database downtime? 0 seconds. Thanks to ASM.
Upgrade to 11g
The only thing is that I search but could not find any document for installing RAC on two seperate servers (64 bit 2003), they are either ASM or Oracle Cluster or Virtual.
I did found some links and documentation on moving from 32 bit to 64 bit.

Keeping my skills and the DBA who is much more qualified then me but with no RAC experience can you refer any document that can guide us step by step. I do not want to get help from our support as they are charging us very high and I do not have that many hours left (part of the contract). I want to take up the task and do it but before I step in I want to cover everything. One last question, for a DBA with RAC experience how much time will this project take?
I took your advice had to convince my boss, and now we have decided to install RAC on 2008 windows with ASM.About ASM:
The Question asked by the SA is how many disks and what sizes do you need?
We have a database size of 800GB and the size on SAN is 1TB.
