Subject: 128 GiB memory question-- kernel only sees 64GiB?
Date: Tue, 22 Jul 2008 10:21:44 -0400 (EDT)	[thread overview]
Message-ID: <alpine.DEB.1.10.0807221019570.8455@p34.internal.lan> (raw)

Hello,

To be able to utilize 128 GiB of memory on a host, does one need to enable 
NUMA support? Currently only 64 GiB is showing up.

As far as machine name/motherboard type, I do not have this information 
currently but I am told there are one or two of these boxes are running 
CentOS 5.x and/or RHEL5/AS.

Is there something special you need to do to utilize all 128 GiB of 
memory?

Thanks,

Justin.
