Hi, I'm looking to run 3cx v9 with 20 concurrent calls going at one time with the recording feature on. Aiming for 80 calls or so a day for each user averaging say 5 minutes a call. Can I get a quick run down of what sort of specs the server would require? I'm looking at the following at the moment. I know 3cx will scale well and it's only 20 users but am concerned I guess only on the disks for when there are 20 odd calls being recorded at one go. Would it be wiser for SAS or would SATA is good enough. Would like to scale it to like 50 in the next 1 - 2 years. Intel Quad-Core Xeon X3430 2.40 GHz 4GB RAM x 2 DDR3 2 x 500GB SATA 7200RPM HD RAID 1 for System 2 x 2TB SATA 7200RPM HD RAID 1 for Data Thanks for any advice.
