I'm still seeing system administrators using the old rule of thumb that swap should be double the memory, even in servers with 32GB of memory.
These systems have relatively expensive disks (shipping with 200GB drives) and allocating 64GB of that to swap seems a bit excessive.
I was wondering how much swap do you allocate for your Solaris servers, and why?
I saw there were other similar questions, but mostly focused on Linux. For Solaris there is another consideration deciding on your swap space because the /tmp filesystem is usually shared with swap.
