64bit/x64 Solaris 10 questions

Hi

I have some basic questions regarding Solaris 10 on Opteron (V40z) and would appreciate some advice.

1. If I run 32-bit Solaris on the V40z will I only be able to use 4GB of memory, even if the server has more. Is this a system-wide limit or just a per-application limit?

2. If I install 64-bit Solaris (x64) on the V40z will I be able to run 64-bit and 32-bit applications simultaneously.

3. Will 32-bit applications running on 64-bit Solaris still only be able to use a maximum of 4GB memory.

thanks in advance

4. If I use 64bit (x64) Solaris will I be able to run more than one 32-bit x86 app using 3-4GB simultaneously on the same system if I have enough physical memory?
