v6 Webclient - I can’t say it’s been an overly positive experience, largely because of browser compatibility issues rather the the design of the webclient itself.
Summary: The vSphere Webclient has been around since vSphere 5.0 but it’s fighting an uphill battle to gain user acceptance. I’ve recently tried using it as my primary administration tool with mixed success.
Recently I’ve been rebuilding my home lab to test out new features in vSphere6 among others. As VMware have been very vocal about moving to the webclient I thought it was about time I took the plunge and started using it in anger – after all it’s been out for several years and like many others until now I’ve stuck with the C# client. Unfortunately I can’t say it’s been an overly positive experience, largely because of browser compatibility issues rather the the design of the webclient itself. To be fair it does seem faster than in earlier releases. VMware KB2005083 lists the prerequisites for the WebClient (both server and client components) but it doesn’t detail the browser specific configuration you need to get it working successfully. This post will cover a bunch of settings you need to make but it’s largely for my own reference as I couldn’t find a single source of information elsewhere.
Browser and server tweaks to make it work
Surely one of the perks of a web based client is no client side setup right? Sadly no. I’m using a Windows 2012 server as my management station for my home lab, which isn’t representative of a real production environment as I’m less concerned with compliance, security etc. While mine is a niche use case some of the same settings apply to desktop Windows editions, especially Windows 8. There are a few configuration changes you need to make on Windows to allow you to work with vSphere via the web client;
- Enable desktop experience (instructions in VMware KB2054049) to allow Flash which is required by the web client (this is only required on Windows Server editions).
- Install the client integration plugin as Administrator, run IE as Administrator. Discussed in this forum post (and this one) though I’ve had mixed success getting it to work at all. Based on the fact that those two forums posts between them have over 50,000 views I’d say this is a very common issue and one that seems to vary with each browser.
- Disable Protected mode (internet and intranet zone) as per VMware’s advice. Obviously this reduces the security but if you’re choosing to use client applications on a server you’ve already made that choice!
- Install the root CA certificate (instructions here) to remove those annoying ‘this site is untrusted’ errors. Alternatively deploy certificates to replace the self-signed one’s that ship with vSphere, although that’s considerably more work!
- Disable pop-up blockers for the following sites;
I’m not sure if VMware publish a compatibility matrix across all their products but I’d suggest you have two different browsers installed so you can switch between them as required. For example IE is supposedly the fastest when using the webclient, but doesn’t work at all when trying to login to the Orchestrator configuration web service.
Tuning performance
Here are a few tips;
- Java heap tweaks are no longer required (unless you’re using NSX apparently – I’ve not tried it myself).
- Tweak Flash settings to allow more local storage
- Modify the web.properties file (just as I was finishing this post I found this Wikibooks entry which covers many of the configuration tweaks covered here. Who knew! Anyway I’m going to publish as I’ve written it now).
- If you’re working remotely be aware that the WebClient can be pretty bandwidth intensive. Use RDP if possible!
Let VMware know what you think
VMware are apparently listening to user feedback, according to this forum post, although in reality it’s largely an outlet for frustrated users!

Hopefully Long-Distance vMotion is only going to get better.
One of the major new features of vSphere 6 is the ability to vMotion over very long distances. With previous releases of vSphere the maximum network Round Trip Time (RTT) was 10 ms which equates to a distance of almost 400 miles. With Long-Distance vMotion the RTT has been increased to a whopping 100 ms which increases the distance to 4,000 miles – far enough to move a VM from London to New York.
Of course you do still require a L2 stretched network (L2 adjacency) which is where technologies like vSphere NSX come in, but what about the storage?
vSphere 5.1 introduced Enhanced vMotion which combined vMotion and Storage vMotion into a single operation so that shared storage was no longer required – essentially Long-Distance vMotion moves all of the storage for a given VM along with its memory.
This does not sound ideal as you would need to move an awful lot of data between London and New York – it is one thing to move a few GBs of RAM, but 100s of GBs of disk per VM is another matter. The answer to the problem is to combine Long-Distance vMotion with asynchronous storage array or vSphere replication.
For vSphere Replication this should be relatively straight forward as it is integrated into the hypervisor and it works at the VM level, storage array replication will be much more of a challenge as typically it replicates an entire datastore containing many VMs.
This is where Virtual Volumes comes in to play as they should allow replication to be controlled at the VM level. Long-Distance vMotion would need to synchronise the replication and switch the active site – sounds like a complex task, but it would bring tremendous advantages and make Disaster Avoidance available over almost any distance.
I am quite sure that this is something that VMware is currently working on with the likes of EMC and NetApp – so watch this space as hopefully Long-Distance vMotion is only going to get better.
Disclosure: My company has a business relationship with this vendor other than being a customer: We are Partners with VMware.
This sounds very interesting and I will be watching how VMWARE develops this technology further.

Chief Technology Officer at perfekt
Stable, scalable, easy to install and has good tech support
Pros and Cons
- "The initial setup is very simple."
- "The integration with containers should be addressed."
What is our primary use case?
While we work with the latest version, we also support customers when it comes to backing up their older versions, meaning we work with a variety of different ones.
Many of our customers have their core infrastructure on vSphere platforms. They make use of the solution for their virtual environments when it comes to their educational and healthcare institutions.
What is most valuable?
We consider the virtualization of CPU and storage resources to be a valuable feature.
What needs improvement?
The integration with containers should be addressed. While they have started to integrate with Tanzu, the integration is not that good at the moment.
For how long have I used the solution?
I have been using VMware vSphere for 15 years.
What do I think about the stability of the solution?
As the solution has been around for a while, it's quite stable.
What do I think about the scalability of the solution?
The solution is easy to scale.
How are customer service and technical support?
We have take advantage of technical support. It is very good.
How was the initial setup?
The initial setup is very simple.
Its duration depends on how big the environment is. Huge ones may take several weeks for implementation, while smaller ones would take several days.
What about the implementation team?
Once the solution is deployed, there is a need for specific maintenance, as there are security vulnerabilities which must be considered, or new features or versions that may be put out.
We provide all the maintenance for the customers. As we also have services organizations, we manage some of these environments on the customers behalf.
What's my experience with pricing, setup cost, and licensing?
As the vSphere platform allows for a variety of additions, it is quite good. There is enterprise plus, enterprise and standard, so the pricing is not too bad.
What other advice do I have?
The solution is mostly deployed on-premises, although we also have cloud deployments.
This product is suitable for a company of any size.
The solution rates competitively against Nutanix and Microsoft. Overall, I feel it to be a pretty proven platform, although the underlying platform, or the management and features that surround it, are of secondary importance. BDI is the main focus.
I rate VMware vSphere as an eight out of ten.

It has an intuitive user experience that simplifies and helps operational management
Pros and Cons
- "vSphere has enabled an enterprise class virtualization environment with a central point of monitoring and management stretched over multiple datacenters (multi-site use), adding all the features of clustering for high-availability and failover, VM migration, and operations."
- "vSphere brings the features required for an enterprise class system with a lot of supporting components: An intuitive user experience that simplifies and helps operational management."
- "As we introduce the DevOps culture, we need to make sure that the principles and tools used to support this approach can be easily integrated and interoperated with the vSphere environment with no (or less) redundancy in tools and functionality."
What is our primary use case?
I have been a VMware Certified Professional (VCP) since 2008 and did several projects for server consolidation on-premise and migration to vSphere-based cloud. Currently, I am working on project to build a private cloud on-premise with Cisco FlexPod (Multipod environment stretched over two datacenters). The Cisco FlexPod includes Cisco UCS (computing), Cisco ACI (networking), VMware vSphere (virtualization), and NetApp (storage).
How has it helped my organization?
vSphere has enabled an enterprise class virtualization environment with a central point of monitoring and management stretched over multiple datacenters (multi-site use), adding all the features of clustering for high-availability and failover, VM migration, and operations.
What is most valuable?
vSphere brings the features required for an enterprise class system with a lot of supporting components: An intuitive user experience that simplifies and helps operational management, e.g. provisioning and monitoring the status of the VMs and the underlying resources capacity.
What needs improvement?
As we introduce the DevOps culture, we need to make sure that the principles and tools used to support this approach can be easily integrated and interoperated with the vSphere environment with no (or less) redundancy in tools and functionality.
For how long have I used the solution?
More than five years.

The High Availability, and flexibility are what we've found to be important for us It's made us a lot more agile.
Pros and Cons
- "We've found the High Availability and flexibility to be important."
- "They need to further develop graphics virtualization."
How has it helped my organization?
It's made us a lot more agile. We don't have to acquire new hardware just to bring it up or utilize new services for our customers. It makes it a lot easier for my team to allocate resources for the other business teams at the company.
What is most valuable?
The most important feature for us is clearly the foundation it provides. In addition to that, we've found the High Availability and flexibility to be important as well.
What needs improvement?
I definitely could see some improvements in Operations Management. That's another product that they have, but it's lacking in a few things. I feel that it's not as aggressive as it should or could be. They have different levels built into it, but I think they should have more aggressive levels.
Another area of improvement would be the further development of graphics virtualization. They've starting dabbling in that, it seems, but it definitely needs a lot more. They need to make it a little quicker and better.
What do I think about the stability of the solution?
I could count on one hand the number of times I've had issues with it and it's generally been related to hardware faults.
What do I think about the scalability of the solution?
It's been very much scalable. When we started using it, we only virtualized a handful of servers. We've since expanded it to virtualize about 90% of our infrastructure at this point.
How are customer service and technical support?
Customer Service:
Not really applicable to my situation. I've always had a good relationship with the regional sales rep but I don't need to contact him very often.
Technical Support:
It's been a little bit hit-or-miss at times. I think that's related to who picks up the phone first. They always get my problems resolved, but sometimes it ends up being quicker for me to figure out on my own than it is for them to get back to me. I've probably rate technical support a 6 out of 10.
Which solution did I use previously and why did I switch?
We evaluated Citrix, but in our testing, vSphere was definitely more stable. Once we got started with vSphere and saw what it could do, we liked it more and more.
How was the initial setup?
The initial setup is pretty straightforward, but it can get complex as you want to use more features. When we first started, it was very, very simple, but we've since made it a lot more complex to account for redundancy.
What about the implementation team?
We implemented using in-house talent.
What's my experience with pricing, setup cost, and licensing?
Make sure you find a good reseller you can trust. I don't have any advice with regard to pricing though, because the product is worth what you pay for it. I definitely feel like I"m getting good value.
Because there are multiple tiers, you want to make sure that you size your licensing appropriately. If you're going to have a stack, you're going to want to weigh the features that are available with the Enterprise versions versus the standard versions and really understand what you're going to get out of it.
Which other solutions did I evaluate?
Yes we looked at Xen server, but we had issues with VM stability. This was over 8 years ago though so obviously that isn't likely the same anymore.
Disclosure: PeerSpot contacted the reviewer to collect the review and to validate authenticity. The reviewer was referred by the vendor, but the review is not subject to editing or approval by the vendor.
Ops Manager is a good product but also requires Orchestrator for automation. Be sure to check out other vendors for this type of thing if you are looking for this. Very well written review of vSphere.
