Hibernation (suspend-to-disk) The hibernation feature (suspend-to-disk) writes out the contents of RAM to the swap partition before turning off the machine. Therefore, your swap partition should be at least as big as your RAM size. The hibernation implementation currently used in Ubuntu, swsusp, needs a swap or suspend partition.

All operating systems require virtual memory, which is a combination of RAM and a portion of your hard drive called the Swap file, Paging file or Pagefile. Whenever RAM is not enough, Windows makes use of the Swap files to temporarily store files and, then, swap them back to the RAM when required. Virtual memory can be considered as being an extension of the computer's physical memory.In Windows 10 this file is named pagefil.sys (invisible to the user), and there's an easy way to adjust its default size or disable it.Change Default Virtual Memory Size on Windows 10Click Start File Explorer.

Old school recommends the Linux swap partition should be at least 1.5 to 2 times of total memory installed. You might have no question to apply this formula on an aging server with probably only 2GB of RAM or much lesser.But nowadays the new servers are easily built with few tens to hundreds of RAM and that means a lot of disk space will have to be allocated for swap partition if you have to apply the old formula.So, what is the new school suggestion? Well, there is a made for installing RHEL 5.4 on x86/64 platform. The RHEL engineers seem have found the relationship between memory workload and swap space utilization.However, it is not easy in practical to precisely determine memory workload before the server is installed with OS and deployed to production. Thus, they suggest a reference of recommended swap space size as follow:At least. 2GB swap space for 4GB of RAM or less.

4GB swap space for 4-16GB of RAM. 8GB swap space for 16-64GB of RAM. 16GB swap space for 64-256GB of RAM.

32GB swap space for 256-512GB of RAMIf there is more than 1 disk drive installed in the server, you should also try to allocate the swap space to multiple disk disks for better overall performance.If there is no dedicated recommendation made for your Linux distribution, then this reference is good for a guide. For those who are using CentOS, guess you know there is no difference between the two distributions.

1. ESX Custom Partition Sizes (original post) Do a custom installation of ESX and make your swap partition 1024 MB instead of the default 542 MB. Later you will need the room when you have to increase your service console memory from 272 MB to 512 (800 MB Max) to keep your systems from crashing when you access them from within a service console window.
2. Hibernation, i.e. On laptops/netbooks, may complicate things a little as IIRC Linux stores memory state in the swap space, so you definitely need more then your RAM size as swap if you plan to use hibernation (and I don't know if that needs to be partition/volume based swap or if file based can be used - it will certainly need to be something.
