[Asterisk-Users] Re: update - 512 Simultaneous Calls with DigitalRecording

[Boris Bakchiev]

The simplest solution and the one already implemented in linux, tmpfs.
It would be best to allocate 4-8GB to tmpfs on /tmp and let the kernel
do the work it was designed to do. And you would not be limited to PCI
bus speeds. The DDR2800 is about 12GB/sec. Some would say "overheads,
etc, etc".
Agreed, even at 95% loss (doubtful) you still get higher badwitch then
PCI bus/hard rive could do :)

Asterisk can be directed to save files to tmp and them you can move the
files to remote server with least possible priority.

Interesting device. Looks like the burst throughput is right on par
with good drives, but you have better sustained throughput and
obviously near zero latency. But what truly is the advantage compared
to having 4 GB (dedicated) RAM in the machine and making a RAM disk
with it? You need the RAM either way and that ought to be at least as
fast as this card on a 33 MHz PCI bus. You loose the "non-volatile"
advantage but that's about it, no?
