Max Calls Spec

[Incubugs]

Hi, so we are moving away from our vps mainly due to costs of vm's with them and setting up our own data centre. The specs are we will have a 100m over 1Gb bearer to start with and a 3 node proxmox cluster and an external shared iscsi storage. Two if the 3 cluster nodes will have 1 VM with 60Gb - 8-Gb ram and 2 10 core procs Intel Xeon E5-2690 V2 - 10-Core 3.00GHz (25MB Cache, 8.00GTs, 130W)Intel Xeon E5-2690 V2 - 10-Core 3.00GHz (25MB Cache, 8.00GTs, 130W), the 3rd node will be for failover if one of the others fails. The VM will not be nat as we will have 10 usable wan ip's however the proxmox vm will be using a firewall provided by proxmox, also the proxmox nodes will communicate over a separate lan and the VM will communicate direct with the cisco router and will be direct WAN Ip's.

The hardware will be Dell servers R620 raid 10 with fibre channels to the storage. Question is how many concurrent calls do you think the VM will be able to handle and what sort of max extensions ? all tenants of course will be domain based.

Thanks in advance.

No-one have any ideas ? a little guidance would be appreciated

The question comes up fairly often and there is no easy answer.
Max concurrent calls are dependent on how the media is handled. Bypassed media, proxied media, transcoding, call recording, etc have different server loads.
Calls per second, BLF updates, registrations, keep alive messages all add load to the server as well.

Every setup is different and every customer is different so the only real way to know the answer to your question is to start testing.
