<span style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:11pt; color:black">I'll chime in as the host of one of the vm setups tested with Jeremie. It wasn't nice. Sipwise is very sensitive to storage latency. It will not run on shared storage
consisting of 7200 rpm desktop SATA drives. I suspect it would run fine on lightly loaded shared 15k sas drives fine. What we found was even 100ms of storage latency would kill sipwise to the point of dropping calls. I now run it on a physical server with
15k sas drives in raid 1 and have no issues and believe in a true carrier class installation this is how it should be. I'll keep my vms for running pbx instances, mail servers and internal systems. They do a good job of that. Anything database / disk io intensive
needs something a little more dedicated. <br>

<div>My response was not to prove or disprove the merits of running your business on a VM. It was merely to illustrate my experiences. I have run sipwise for about a year and a half and have learned the ins and outs of having it to run well. Out of the box
sipwise works and works well. It will handle the load they say it will and not break a sweat. In my experience it works best on a physical server but in your situation if it works well as a VM that's great. If you need help I would be glad to help. Also Kevin
is very knowledgable in everything sipwise. <br>

<p class="MsoNormal">We tested our sipwise on several VM style setups from amazon to linode and an in house VM with very poor results. Even with a light load we were able to crash a linode servers hard drives. If you want to truly provide high quality service
put sipwise on a physical server with 15K rpm sas drives and it will handle whatever you throw at it with ease. <br>
