Linux Installation
we are actually replacing our oracle apps and oracle db servers and both servers are running on oracle enterprise linux. since we are purchasing new 64bit architecture (fujitsu pyrx300 s6 model servers one with 16gb mem and 32gb mem. presently the existing servers are connected to san. since we are going for the new ones we are going to install oracle enterprise linux 6 on x86 64 on both new servers. beofre doing this we need to know the best installation pratices. even though we had gone through sites regarding this, we would like to have the best steps.
the total hard disks are going to be
hd 6g 300gb X 6 no:
what would be the parition size to be kept for each imp file systems.
the existing file systems of database and apps servers are as
db server

i have received the new servers today and just wanted to know that since it is having 6 hdd's of 300gb how about having two hdds mirrored for OS ans rest 4 hdds in raid 5 . the idea is that we can have better OS reliablity and production data is going to be in san.
is there any other solution to have a better scalability

thanks for the best practises and tips for hardening the server. the server is configured with raid 5 and data is yet to load.
thanks for the replies

2) windows partitions doesnt exist here
3) our db and apps are mission critical and at the moment we wont be having any redundancy as we are going to have one server for apps and other for db. (multiuser)
once we set these two serves we will have a dr server (singlenode) for any disaster.
apart from these we have san where we will connect our db server to san for better capacity and i/o performance
hope x86 64 will be compatible for apps 12.1.1 and db 10gr2
