Looking for some guidance on disk space for Swap. What is the recommended disk space to allocate to Swap?
finid on Aug 25, 2011
Disk space assigned to Swap depends on the amount of installed memory or RAM. Current recommendation goes like so:
4GB of RAM or less === a minimum of 2GB of swap space
4GB to 16GB of RAM === a minimum of 4GB of swap space
16GB to 64GB of RAM === minimum of 8GB of swap space
64GB to 256GB of RAM === a minimum of 16GB of swap space
256GB to 512GB of RAM === a minimum of 32GB of swap space
These were taken from a current installation guide for Red Hat Enterprise Linux 5.
Keep in mind that the old recommendation to assign 2*RAM is, well, old. It no longer applies today.
