How much swap space is needed for 32 GB RAM?
Hi,
Platform: Linux x86-64 with 32G RAM and 770 GB available RAID disk space

In my case, the required swap space would be 32 GB * 0.75 = 24 GB. My SA allocates only 4 GB of swap space. Do I really need 24 GB swap space? What is the appropriate amount of swap space in your opinion? Thanks, Simon0
