Linux memory optimisation in 64bit IBM processor


Hi All,

Its my first thread in my SDN.

We are about to migrate a new system in our environment

The new hardware will be IBM x3500 64bit with 20GB and for some unavoidable reasons we are planning to the use this system as 32 bit OS

I am aware if we use the system as 32 bit we have to compromise the memory and performance. But I like to know will this cause a performance problem in SAP or we will not be able to avail the complete usage of memory in the applications and also in case of hardware issue will IBM support us?

Kindly give your thoughts and with your inputs i can take it up further.
