Thanks for response.
How do I derive the requirement? I need to size IO system to record multiple
calls concurrently.
I ran test with following configuration
Quad Core Xeon with 4GB RAM
250GB SATA disk (No RAID)
Linux (CentOS 5.9)
Asterisk 1.8.20
I'd suggest testing your system while monitoring with top and iotop
(which should be a "yum install" away).
That should show you your bottlenecks.
It looks to me like Asterisk doesn't do compression until the call is
ended, so recording to a compressed format would actually increase IO
load (write, read and compress, write compressed data).
