Hi, I have loaded CentOS 5.6 on HP DL 180G6 2U Rack Server and the physical RAM is 32 GB. As per http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-swapspace.html It says it should be 1 x of Physical RAM or less. Not sure about the "less" word in deciding swap space size Please suggest/guide further on what all parameters i should decide to set swap space. Regards, Kaushal
