Question RHAS2.1 Itainium - Max swap size?


Anyone know what is the maximum swap size allowed in Red Hat Advanced Server 2.1 for Itainium?

Does the 2GB per partition still carry over from x86?

I need to create a single 16GB swap partition.

thanks!

To the best of my knowledge the 2GB swap partition is still the limit. I do not however know if the 8GB limit of total swap space still exists.

What on earth do you need 16GB of swap space for?

The system we have has 16GB of physical memory installed and we're still following the age-old rule: minimum swap = total physical memory

I see many recommendations to make SWAP space equal to your physical RAM or TWICE your physical RAM, however, I don't think those rules hold when you start getting above 1GB or so of RAM. The only reason to have SWAP is when you run out of physical RAM, something that is highly unlikely with 16GB, depending on your specific application.

Take a look at the swap space mini how-to here:
http://www.xenotime.net/linux/doc/swap-mini-howto.txt

For my opinion, if you have a system that USES 16GB of physical memory, and NEEDS 16GB of swap, or almost any swap for that matter... you need to get more memory. Obviously this is for a commercial application, and whatever it is serving would be better served without having to rely on that much swap.
