I've got a server only running the single cpu kernel. I am going to be upgrading it today to the multi-processor kernel (going from 2.6.9-5.EL to kernel-smp-2.6.9-78.0.8.EL.) My question is, the user is planning on maxing out the RAM in this box in the near future (32gigs) which means I will need the hugemem kernel, correct? The only thing I see on RHN is the hugemem-devel package. I had thought there was a kernel-hugememsmp available. How do I install hugemem using just the devel rpm?
anomie - the Redhat link doesn't give any idea about what the "hugemem" kernel is ... or why it might be a bad idea.
I was originally going to object that we didn't even know if the op had Redhat ... until I noticed the cryptic reference to "RHN" (Red Hat Network, rhn.redhat.com).
But again - if you *can* go to a 64-bit CPU, then you *should* go to 64-bit.
Otherwise, if you're required to stick with 32-bits (for any number of perfectly good reasons), you should consider "hugemem" *only* as a last resort. It adds an extra level of indirection to your memory addressing, and an extra level of complexity to the OS.
