Hi,
I'm posting this to -hackers, since there was a related thread just recently. If this is unappropriate and would belong to -questions, please accept my apologies.
We've just bought a Dell PowerEdge 2650 with Dual Xeons and 2 GB of RAM. I thought I would just install it the usual way, which would include reserving 4 GB swap. Now I'm not sure if I would run into problems, as this would match the entire address space. There has been a recent thread about someone who ran into possible problems because of that.
I wonder what I could do to prevent any problems. Is is advisable to increase the kernel address space (KVA is this?) in my custom kernel?
I've found in the handbook (could also be the FAQ) a paragraph that stated, if the hardware (MMU) would support it, FreeBSD could address 8 TB of (I guess virtual) memory. The poweredge can even be equipped with 6 GB RAM, which is already past the 4GB limit of a standard 32bit address space. So I wonder if it would be possible to just use the memory as usual?
I don't know of the Xeon's have a different MMU which enables to address more than 4 GB, but from my guts I would doubt it. It seems that some people have machines like this in production. So any hints or advice would be appreciated.
Thanks & best regards, Daniel
