| *[[home_server:home_server_setup:summary]] | As I have a computer with enough memory I see no need or value in a SWAP partition. In fact as I am using a SSD for the system drive a SWAP is a concern to the reliability of his drive. The following is a list of method to check and disable SWAP function. |
| *[[home_server:home_server_setup:home_it_setup]] | *The command ''sudo swapoff -a"''turns of an existing SWAP partition. (''sudo swapon -a'' turns it back on) |
| *[[home_server:home_server_setup:Network_setup]] | *To prevent a SWAP partition being mounted at boot comment out the swap partition in /etc/fstab, ''sudo vim /etc/fstab''. (Another open is to instead use the swapoff -a command in a boot cron job. This allows the swapon -a option to be later used.) |
| *[[home_server:home_server_setup:kvm]] | *The command ''free -hw'' shows the current memory status. |

| *[[home_server:home_server_setup:disk_check]] | *[[http://askubuntu.com/questions/214805/how-do-i-disable-swap|How do I disable swap?]] This article also refers to another that explains why turning of SWAP, even with a lot of RAM, may not be best, however this was written at a time SSD were not common and system RAM availability were in general significantly lower. |

It is interesting that this article also warns against use of SWAP partitions with SSD storage. This article also mentions the swappiness and vfs_cache_pressure setting. |
