On a modern server without IDE drives, you dont even need RAID to
accomplish this. Problems arise at around 50-60 calls in my experience
(HPDL 360, 3Ghz, Gig of RAM and RAID 1 mirroring. I run a cron job that
checks files sizes and when they do not change within a specified period
of time, they are considered complete and are FTPed to another server
running SOX to MUX and compress the audio.
Above that, checkout Orkaudio or RAMdisk. Orkaudio has my praises right
now. The team over there has tweaked a recording server for us to
handle about 200 simultaneous calls and all the recording is done
passively through Pcap and mirrored switch ports.
Thanks,
Steve

Hey i said that as per his requirement as an example :) . His
requirement is just around 20 calls . For a moderate server i think
sata raid should be fine ..Heres some result posted by someone for
recording calls on ram disk .

Hehe, UDMA sounds like EIDE drives.. nice to see they are fast
enough,
but I do not recommend those as server hardware. ;-)
But, if John is going to buy a extra new server, he could use two
drives
in a mirror setup extra for recordings of these files. As it is
not only
the frequency of reading/writing these files but other accesses of
the
media like starting programs or reading/writing of logfiles that
slowes
down the access to the recorded audio files.
