we have CENTOS 4.7 (X86) on DELL server, I already put 32 GB RAM on it. I can use "top" or "free" to check memory and it did show 32 GB.
I check REDHAT site and found it say:
The "SMP" kernel supports a maximum of 16GB of main memory. Systems with more than 16GB of main memory use the "Hugemem" kernel.
I use "uname -r" to check kernel and it show:
# uname -r
It did NOT show "Hugemem", does this server kernel support 32 GB or not? If NOT how can I change kernel to "hugeme"?
