3. mmap storage : max i can configure is 340 GB.
I was able to use only 340 GB of cache. any size after this, i would get error.

I was having this issue too.  After some googling it appears this is a
AMD64 Linux 2.6 issue.  According to
http://lists.humbug.org.au/pipermail/general/2004-July/024139.html

"It maybe important to note that as of the latest 2.6 kernels, Linux on
the AMD64 platform can only memory map a 340GB per process. This is due
mainly to a VM paging system ported from the ia32 platform that should
have been left on the hillside at birth to die. I have not tested *BSD
because we have not done enough research to confirm if the Linux
emulation works on AMD64 for AMD64."
