Re: RHEL5 Ram and Disk Partiton

Gentlemen,

for the Size of the SWAP it should be double the RAM
Quoted from Redhat site
"A swap partition (at least 32MB) — swap partitions are used to support
virtual memory. In other words, data is written to a swap partition when
there is not enough RAM to store the data your system is processing. The
size of your swap partition should be equal to twice your computer's RAM, or
32MB, whichever amount is larger."

Kind Regards
Samer Azmy
