can you share info about your virtualization? versions?<br>
can you share your test-suite ?<br>

<pre>Hi,<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>My latest performance tests on a Dell R320 (4 cores @2.2GHz) with a pair<o:p></o:p></pre>
<pre>of PRO as only VMs on that host and 1 vCPU per host with 8GB RAM shows<o:p></o:p></pre>
<pre>that we top out at around 15 regs/sec and 10 calls/sec, with the CPU<o:p></o:p></pre>
<pre>being 100% utilized. IO is not a problem in this setup, iowait is pretty<o:p></o:p></pre>
<pre>much 0 with the disk utilization maxing out at ~50% in peaks.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>The number of regs it can do without calls is somewhere around 80<o:p></o:p></pre>
<pre>regs/sec, but if you add some calls, it degrades quite quickly.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Whether or not it's still sufficient depends on your number of<o:p></o:p></pre>
<pre>subscribers you plan to put onto one VM, and their typical Expiration<o:p></o:p></pre>
<pre>time for registers. All in all it could still easily do ~10k subscribers<o:p></o:p></pre>
<pre>with a 1 hour re-registration rate, where you'd end up with ~1800<o:p></o:p></pre>
<pre>concurrent calls at 10calls/sec. Not too bad for 1 vCPU. Your mileage<o:p></o:p></pre>
<pre>might vary though.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>As a comparison, on the same server in bare metal (4 cores @2.2GHz at<o:p></o:p></pre>
<pre>32GB RAM) you can do 250 regs/sec with 50 calls/sec without issues.<o:p></o:p></pre>

<pre>Dear Stephen,<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>This is super to hear you trust Sipwise NGCP as a basement for your own<o:p></o:p></pre>
<pre>company! In short there is no strict limitations to run on<o:p></o:p></pre>
<pre>virtual environment. While there some known minor issue there, like<o:p></o:p></pre>
<pre>sems eats ~5% CPU when doing nothing (on polling new sip packats), etc.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Sure the hardware and software you choose for virtualisation is very<o:p></o:p></pre>
<pre>important. The IO speed and latency is always a problem of any virtual<o:p></o:p></pre>
<pre>env. Also VM neighbours sitting on the same hardware can create lack of<o:p></o:p></pre>
<pre>IO in the most unexpected moment. So, be careful with sharing hardware<o:p></o:p></pre>
<pre>with other VMs. NGCP relies on IO a lot.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>For the high performance and high availability we recommend you to try<o:p></o:p></pre>
<pre>our PRO solution. It guarantees 50 cps rate providing high availability<o:p></o:p></pre>
<pre>for already established calls. Feel free to contact <a href="mailto:sales@sipwise.com">sales@sipwise.com</a><o:p></o:p></pre>
<pre>for more information.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>In the same time please share your experience with SPCE in virtual<o:p></o:p></pre>
<pre>environment. We see the good theoretical possibilities there.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Thank you!<o:p></o:p></pre>

<pre>Some (fuzzy) memories from a few years ago:<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>SPCE seemed to do okay running as a VM on xenserver until we reached a<o:p></o:p></pre>
<pre>certain threshold of concurrent calls, I don’t remember that number..but<o:p></o:p></pre>
<pre>it wasn’t very big. It seemed that IO wait was climbing at times,<o:p></o:p></pre>
<pre>causing call processing issues. The storage system in question was a<o:p></o:p></pre>
<pre>ZFS RAID Z2 array comprised of 7200rpm desktop class drives that were<o:p></o:p></pre>
<pre>not the fastest in the world by far. It was at that time I decided to<o:p></o:p></pre>
<pre>move back to bare metal and not look back.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Now that I have my own company, I’m again looking at virtualization as<o:p></o:p></pre>
<pre>an option for high(er) availability being that a single hardware failure<o:p></o:p></pre>
<pre>will not take the infrastructure down.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>What amount of concurrent calls and/or calls per second could I expect<o:p></o:p></pre>
<pre>to process given a certain amount of hardware?<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>The physical hosts in question will be dell R610 boxes with 2x xeon<o:p></o:p></pre>
<pre>x5550, 32GB RAM. I plan to only run voice servers on this platform,<o:p></o:p></pre>
<pre>I’ll have another resource pool for other workloads.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Since my last experience, xenserver has been greatly improved, as I’m<o:p></o:p></pre>
<pre>experiencing running most of my other servers on it at the current time.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>If it’s not a good idea, tell me so, I’ll go another way, I’m looking<o:p></o:p></pre>
