vSphere Web Client 6.0: working remote via tethering. Bandwidth comparison RDP vs. local Browser

When I first installed vSphere 6.0 I was pretty impressed about the performance gain of the vSphere Web Client. Finally the Web Client is a tool I can work productive with and mustn’t be afraid to be marked as unproductive from my customers (it’s tough to argument a higher hour-rate if I wait 20% of my time for the UI 😉 ).

So my homelab was installed with vSphere 6.0 and I tried to connect to it via VPN from my hotel wifi. Since the wifi was blocking my VPN attempts I was forced to tether/share the internet via my smartphone.

Sharing internet on… starting OpenVPN against my homelab… opened Chrome to use the Web Client and.… the useability with the Web Client 6.0 was really really good.

After a few minutes I received a warning by my provider T-mobile that my data plan has reached the 80% thresholds. I know 500MB included in my data plan is not that much, but still I was really suprised seeing this OpenVPN statistics after a few minutes.

Since I haven’t used any other services than the vSphere Web Client I wanted to know how much bandwidth working in a local Browser via the Web Client really needs.

I created a test-case (it’s Sunday, weather is bad, Bundesliga is pausing) which should take around 3-4 minutes:

  1. Login to the vCenter via the Web Client
  2. Navigate around in the home menu
  3. Select Hosts and Clusters
  4. Choose an ESXi Host and navigate to Manage / Settings / Networking
  5. View the vSwitch, virtual adapater and physical Nics settings
  6. Go to related Objects and select a datastore
  7. Browse the content of the datastore
  8. Create a new VM with default settings
  9. Power on the VM

I did this test with 2 Browsers Chrome and Firefox (to make sure the results are nearly identical) and observed the results via the activity monitor of MacOS. As a 3rd alternative I have chosen to use a remote connection via Microsoft Remote Desktop (native resolution, 16 Bit color) and did the same test-case steps mentioned above.

Here are the results:

  1. Chrome – duration: <4 minutes, bandwidth: ca. 21 MB
  2. Firefox – duration: < 4 minutes, bandwidth: ca:26 MB
  3. RDP – duration: < 3.5 minutes, bandwidth: ca. 2 MB

Of course there are a lot of factors not considered (high activity on the vCenter that might increase the data most certainly), but the numbers should give you a feeling that the better performance of the Web Client seems to come side by side with a pretty bandwidth sensitive caching on the client side. So if you work with limited bandwidth or any kind of throughput limitation use an RDP connection to a Control-Center VM within your environment that is able to use the Web Client for your daily vSphere operations.

Linux and the Web Client in vSphere 5.5

If you use Linux and read the vSphere 5.5 release notes you might have noticed this:

vSphere Web Client. Because Linux platforms are no longer supported by Adobe Flash, vSphere Web Client is not supported on the Linux OS. Third party browsers that add support for Adobe Flash on the Linux desktop OS might continue to function.

Puhh, pretty bad news! I found out VMware’s vSphere Web Client in 5.5 requires Adobe Flash 11.5 whereas Adobe provides flash for Linux only up to version 11.2. As a result, starting Web Client with Firefox on Linux you see this:

Here is the good news: It works with Google Chrome:

For your information I copy my software package versions so you know what exactly I am working with:

vxltsupport@desktop:~$ dpkg -l | grep -E "flash|firefox|google-chrome"

Should you be aware of any other browser or flash plugins that work or do not work, please drop me a mail to mathias.ewald@vxpertise.net and I will add the information here!

Web Client becoming more and more important

I have to admit.: Although I know I would have to get used to VMware Web Client, I’m still doing a lot of tasks in the good old .NET client. But I just recognized that I couldn’t edit the virtual machines hardware settings of a hardware version 10 VM:

hw10

So the vSphere Web Client Server is getting more and more a very critical component in your environment, since one day we probably won’t be able to use .NET Client even for basic administration tasks.

Seriously, VMware? …(a not so serious article)

Since I’m really kinda busy with my master’s thesis at the moment, I lack time to write about really important things right now … unfortunately. But luckily, I’m not busy/dedicated enough not to write about ***** icon wink Seriously, VMware? ...(a not so serious article)

Look at this and find the mistake:

Sorry we lost this figure due to an HDD crash. We are going to replace it soon!

Found it? No??? Then look again:

What could be wrong about a performance chart showing four metrics with only 3 line graphs? Well, the 3rd one is in WHITE color … Common icon biggrin Seriously, VMware? ...(a not so serious article) Luckily, we’ve got the new vSphere Web Client – which displayed the same chart correctly;

I will come back with the real stuff in about a month…the idea catalog is full of interesting topics…

So long!
