I am currently looking at setting up a server with the following specs:
Dual Xeon 3.2
RedHat Enterprise Linux 4 - 64 bit
8 GB RAM
4x400 GB SCSI drives in Raid 5
My main concerns are as follows:
1) Will Cpanel run stabily on a 64 bit system and be able to address and make use of the larger amount of RAM. I first and foremost want to ensure the server would be stable and the software run properly.
2) Will PHP, Apache and Perl all function properly and be able to use the larger amount of RAM.
3) For any 32 bit applications that are running will they only be able to access 4 GB of RAM rather than the 8GB? If this is the case and the above apps only use the 4 GB of ram rather than 8 GB would it not be worth having this much RAM.
As an option I could enable Physical Addressing Extensions (PAE) and recompile the Linux kernel however I am not familiar with this enough to know if there are any drawbacks to doing this or if the server will become unstable.
If anyone can share their thoughts on this it would be appreciated.
