[asterisk-users] IOPS required by Asterisk for Call Recording

[Amit]

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 failed to record more than 80 calls.

If I run test with simple IVR, I achieved 400+ calls with same server.
So write seem to be an issue.
Is there any way to tune / optimize / configure for better write performance?

I am not sure if I need to post this query on developers list? Please guide...
