Minimal issues encountered.
What do I think about the scalability of the solution?
Minimal issues encountered.
How are customer service and support?
Customer Service:
8.5-9/10
Technical Support:8.5-9/10
Which solution did I use previously and why did I switch?
I have experience with Microsoft Hyper-V, but production has always been VMware
How was the initial setup?
It's very straightforward for the hypervisor (ESXi/vSphere), but View (Desktop) is more complex, and needs extensive planning in an environment like ours with 15,000+ desktops.
What about the implementation team?
Hybrid. We brought in expertise from the vendor and reseller during the initial setup, and I would strongly suggest consulting. Expertise for initial deployments as the focus of a corporation, is the not the deployment, but the running and extension of the environment. Architecture and design is critical and specialized, and we used external resources.
What was our ROI?
This is always an issue. The ROI is heavily laden with soft dollar savings on an existing environment. Look two to three years out and make this a strategic decision rather than a tactical one and the ROI will be realized.
What's my experience with pricing, setup cost, and licensing?
Price/License – Free is not free. Review what capabilities you want to have v need to have and then select the appropriate license. With that said, “Good Enough” is a valid stance now. You do not need to get everything you want to make it successful.

We leveraged it to help us with our DR following power outages. However, we don't necessarily have a need for the expensive add-ons.
Valuable Features
- High Availability
- computability
- vMotion
- DR
Improvements to My Organization
Our DR count changed – we had quite a few power outtages that opened our eyes to DR and by leveraging vSphere we are able to get to our goal.
Room for Improvement
I know a lot of the stuff that we have issues with have been addressed in v6 like template management. Some of the add-ons are expensive without a specific large need.
Stability Issues
Very stable – its great.
Scalability Issues
Easy – very easy, expecially with Nutanix. It takes longer to get the hardware than to deploy it.
Customer Service and Technical Support
I’d say 10/10 – we’ve never had a problem that wasn’t solved right away if we have to call.
Initial Setup
It was straightforward.
Other Solutions Considered
We looked at a couple others and VMware was just better because of vMotion, its ease of management, and the interface.
Other Advice
Peer reviews are pretty important, more so than online resources.

Vice President, Systems Architect at a financial services firm with 1,001-5,000 employees
vMotion helps with core banking operations and time-to-market, but I'd like to see self-discovery of assets.
Valuable Features
- vMotion helps with core banking operations and time-to-market
- We define architecture tiering
- Availabity is important
- Lots of compliance requirements, so being able to maintain application and business continuity
Improvements to My Organization
It's helped bridge business requirements into infrastructure. Because of the cut down in provisioning time, we’ve proved that VMs are valuable as assets, and helps establish trust between business partners and IT department.
Room for Improvement
I'd like to see the self-discovery of assets and integration of application profile into different assets. Also, the challenge we have is deploying an asset into a datacenter.
Stability Issues
It’s very stable. Lots of fear in the past (“my application not a candidate for virtualization”), but we’ve proved them wrong.
Scalability Issues
It's very scalable, we have three core data centers and six to seven virtual data centers, and whenever possible, we consider VMs as first choice (can’t disclose numbers).
Customer Service and Technical Support
Some applications don’t perform well, so we engage our TAMs. The VMware engineering team works with TAMs.
Other Advice
Don’t hesitate, and go get it. From an architecture perspective, plan out a typical deployment, but you need to understand the business requirements and challenges, be able to define requirements, and make sure you choose the right-size server farm.

Network/Systems Administrator at South Plains Electric Co-Op
We were able to scale up from 10 to 80 machines, something we couldn't have done with physical servers. Training, however, should be made more available.
What is most valuable?
- Ease of upgrading
- Ease of backups
- Ease of deployment
How has it helped my organization?
We now have a quicker deployment of machines, as it’s been far more cost effective than our physical servers with a smaller footprint.
What needs improvement?
It’s pretty good the way it is, I can’t think of anything else I need.
What do I think about the stability of the solution?
It’s very stable.
What do I think about the scalability of the solution?
We started with maybe 10, we’re up to 80, and it’s been very easy to add them all on.
How are customer service and technical support?
I’d say they were very good, they’re very quick and responsive, I can’t think of them ever not being able to an issue.
Which solution did I use previously and why did I switch?
We were running physical servers, the industry was headed that way, and we knew that we had to. Furthermore, 80 physical servers is too much to fit into one room.
What about the implementation team?
I didn’t set it up, but I think they had a consultant come in.
What other advice do I have?
Probably the availability of training is the most important thing to look at when choosing a vendor. It’s not perfect but it’s pretty good, and VMware is great.
Peer reviews are pretty important, it’s an easy way to look at hands on market research that you don’t have to pay for, to be honest.

Systems Services Representative at a financial services firm with 10,001+ employees
We've moved our secondary products to a virtualized environment. The web client in version 6.0, though, is inferior to the Windows client.
Valuable Features
- Training is really great
- Ease of use
- Ease of implementation
Improvements to My Organization
It's opened up new services for us that we can offer to our customers. We've moved all our secondary products to virtual environments, so we're able to offer other physical hardware, and have our system simplified.
Room for Improvement
I'm not a big fan of the web client, and would have liked to have had them stick with the Windows client, as the web one is quite a bit different.
Stability Issues
It's very stable, and just works which is one of the reasons we went with it instead of MS Hyper-V. It's more robust and feature rich than Hyper-V too.
Scalability Issues
Very scalable, and we can serve a wide range of clients with budgets ranging from $20 million to $20 billion.
Customer Service and Technical Support
They're knowledgable, and willing to help, but it's not as instantaneous as I’d like, but they do eventally answer.
Initial Setup
It's very easy. I wan't involved in the early stages, and I came in when v5 was in place and when lots of infrastructure was already set up.
Pricing, Setup Cost and Licensing
I’d recommend it, but take time evaluating to see which parts you need, as it can be a little more expensive, but it seems to work. Also, be sure to have a lengthy POC.
Other Advice
Nothing’s perfect, and they are docked points for moving to a web client. Also, single sign-on is unfriendly, and there were growing pains.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
Different is right but having a 'fat' client means more support and work for VMware, would rather than concentrate on hosting than client software. A Web site means that Linux, MAC and non-windows based shops can use the client as well..
Making people use windows to support Linux isn't a great idea at all.
Sr. IT Technical Engineer & Solutions Architect at a hospitality company with 1,001-5,000 employees
When we release our new applications, we just scale out without investing in new infrastructure. It's missing centralized management, however, which limits our troubleshooting ability.
Valuable Features
The level of consolidation that you can implement from a hardware reduction element – it is so valuable to us in our industry. Ease of use and simplicity.
Improvements to My Organization
The cost savings in itself from having to buy 15 servers in each hotel. Now we have one server for each hotel. When we release our new applications, we don’t have to invest in new infrastructure, we just scale because its already in place. We're on a five-year lifecycle so we can scale for five years with no further investments.
Room for Improvement
Centralized management could be better. A server can only be managed by one vCenter. This limits our visibility to remediate, troubleshoot and fix problems efficiently.
Stability Issues
It's very reliable. They're is not another product similar, and we've had no major outages for seven to eight years. We have hotels where you can barely reach and because of the stability of the product they can trust the reliability.
Scalability Issues
It grows beyond belief. In my situation, because Im always dealing with corporate, I have shown that virtual machines can scale to whatever we have asked it to do. If we need to scale we can, and the hardware just needs to be ordered, and setup.
Customer Service and Technical Support
I love them, they are the best in the world. We only call in emergencies, and they are the best in the world. We are changing to v6 and the support model is changing so we to procure the enterprise support even for the basic offices. In the earlier versions, I had it but now we're trying to persuade VMware for that additional 24/7 service.
Initial Setup
It's straightforward, and couldn't be any easier. I did training around the world for IT resources, even teams who have never seen it can adopt it, both in terms of administrative and installation.
Implementation Team

Network/Systems Administrator at Tidewell Hospice
It's allowed me to aggregate resources, including reducing the number of physical machines from about 200 to 30.
Valuable Features
The ability to aggregate resources.
Improvements to My Organization
We have saved money, reducing the number of physical machines. I probably would have had a couple hundred machines and I now have about thirty.
Room for Improvement
I can't even think of anything – it does everything I need it to.
Stability Issues
I love it – over the years its been one of the most stable platforms I've ever dealt with. The platform is more stable than the OS running on it.
Scalability Issues
I think it’s great. It’s been able to grow even as we care for more and more patients.
Customer Service and Technical Support
I love it. I’ve had great experience with VMware support – they have never failed to resolve an issue or understand how we got there so I don’t get to that issue again.
Initial Setup
I wasn’t there for the initial setup, but it's very straightforward.
Other Solutions Considered
When choosing a vendor we look at
- Support
- Usability
- Cost
You should also talk to someone knowledgeable not just online research – someone who can help cover questions that wouldn’t normally get covered.
Other Advice
Peer reviews are important but not the highest. There are a few groups I look to specifically, one of which is Spiceworks, but I respect the people I’ve dealt with.

Senior Systems Administrator at a energy/utilities company with 1,001-5,000 employees
It provides us a global standardization, ease of management on a global level, and helps our remote sites for those who don’t have a sufficient tech level. Training for it is expensive.
Valuable Features
Old school stuff - power savings, ability to consolidate, licensing savings, and ease of management. All the new features are great, but they’re just iterations of an already awesome product.
Improvements to My Organization
It provides us a global standardization, ease of management on a global level, and helps our remote sites for those who don’t have a sufficient tech level.
The core savings is huge and allows for quick and deep provisioning. It’s getting harder and harder to remember how physical servers work.
Room for Improvement
Ditch flash-based web client, make it HTML5. Would like more customization of the web client to make it do what I want. I occasionally flip to the old client because I know it. Web client is a better solution, but it's not done right.
Make training more accessible. Right now very expensive and hard to see the value. Lowering cost would be huge.
Stability Issues
Extremely stable. There’s occasional bugs, but very rare.
Scalability Issues
Very scalable, eventually do run into licensing costs, but the platform itself is scalable, almost infinitely. The business around it limits scalability.
Customer Service and Technical Support
Used tech support on couple of occasions, but no system-down type issues, just minor bugs.
Initial Setup
Easy to set up, not difficult, but more difficult to implement it the right way, especially for larger organizations, but that’s just knowing the platform. You have to do homework, and know what you’re doing. If you link vCenter, you must make sure, for example, to do it correctly (like MS SQL, you must know to separate logs and data files, etc.).
Pricing, Setup Cost and Licensing
It loses points on cost, as there are free solutions, but we don’t want to use them.
Other Advice
Depending on the size and budget, if there's a smaller shop with less money, and you could get by with just a couple VMs, vSphere would be difficult to recommend. But if you're larger with more money, it’s the best platform for virtualization and cloud integration. VMware is further along than anyone else in this regard.
