Would that be 32 or is it better to “reserve” two CPUs for the system and therefore leave 30 vCPU available?

VMware has no information what so ever that I can find regarding foundation edition. I have a case open and they are answering all questions but how to get it. Fishy... They made big deal out of it on VMworld, but again with vague information. I heard some rumor that it will be separately released mid November, but no one seems to be able to confirm that.

In USA and UK XenDektop is the most choosen VDI solution than VMware View. Spoken to many engineers in large company's they have choosen for XenDesktop because of TCO and performance.

From your video(btw, great video!) and from my testing, the physical switch connecting to 2 ESXi hosts can just define all vlans as regular vlans, the traffic will pass ok with end points as VDS doing private vlan. In your case, you just defined 4 regular(non PVLAN) vlans 23-26 and everything runs good. I think Vmware note is inaccurate. You need don't need PVLAN enabled on a transit physical switch. any thoughts?

Switch Dlink exact model unknown, 48 port enterprise class, 19" rackmountable, no other traffic there only my ESX hosts. - no other virtual machines installed/running on those hosts. This was dedicated platform for my testing only. - virtual machine v7 and v8 - Mikrotik linux distribution , versions v5.7, v5.15, v5.17 and current latest v5.20 tested. Each VM allocated one core, later two cores in repeated test which honestly didn't change the results at all. 512MB vRAM as it's plenty enough for this system and test (used around 40MB RAM only, hey this is linux right), vmxnet3, e1000, e1000e virtual adapters. Seems like the version of Mikrotik had absolutely no influence on result of test, read more below. There is built-in test in those Mikrotik distributions enabling user to test with random or compressible data. It is possible to have receive/send/both streams. Compressible data heavily load CPU as expected and is not representative measurement due to variations, but random generated uncompressible data leads to repeatitive statistically meaningful results as there is extremely low delta in results : usually it is within 3% which is excellent. As far as I understand, the built-in throughput test in Mikrotik is based on iperf. Mikrotik has their own CLI so it is not standard linux command line thus no verification of this is possible. But I think this is not important, as far as we believe the vendor and generate packets (for sure they are not read/written from disk !! easily verified) and those packets are not compressible (verifiable but sorry I won't capture the traffic and analyze it afterwards), the test is performed in absolutely repeated and correct way. Now the results : vmxnet3 gives little around 400Mbit/s throughput (380 to 410Mbit/s) while E1000 and E1000E both yield 990Mbit/s throughput with minimum of 975Mbit/s. Let me stress out stable and repeated EVERY TIME so this is extremely consistent, with every setting, every version of ESX, Mikrotik in virtual machines. This leads me to think : is the VMXNET3 driver in Mikrotik flawed and not working optimally ? The answer is probably no. Explanation - the result of 400Mbit/s I achieved with VMXNET3 is extremely aligned with the result presented here in your blog. The only huge difference is with the E1000/E1000E results where I have three times as much performance. I'm presenting detailed description so anyone of you can re-test. If you see any problems in my "methodology", let me know. So no eggs are created equal and it is heavily possible that E1000/E1000E are FASTER than VMXNET3. I dare to re-test this with Windows 2008, 2003 and Windows7, stay tuned :) Sat, 13 Oct 2012 20:00:06 +0200 http://www.ntpro.nl/blog/archives/1932-guid.html#c2649 http://www.ntpro.nl/blog/archives/2178-Cool-Tool-PsPing.html#c2647 http://www.ntpro.nl/blog/archives/2178-Cool-Tool-PsPing.html#comments http://www.ntpro.nl/blog/wfwcomment.php?cid=2178 nospam@example.com (Alex Muetstege) Just to be lazy, I use a GUI tool for this called MTR. MTR stands for Matty's TraceRoute or MyTraceRoute (depending on who you ask) and orignally was a Linux alternative for the traceroute command. It merges ping and ping stats with traceroute info so you cannot only see what the latency to your destination is, but also check where your latency on route is caused (i.e. faulty router config or bad transit somewhere). The Windows version can be downloaded at http://winmtr.net/, the original site can be found at http://www.bitwizard.nl/mtr/. There also is an OSX transcode (Cli version) but you can also download the sourcecode and compile it, see http://www.practiceofcode.com/post/457590665/compiling-mtr-for-mac-os-x-snow-leopard. My 2 cents about this :) Fri, 05 Oct 2012 10:25:35 +0200 http://www.ntpro.nl/blog/archives/2178-guid.html#c2647
