824,106 professionals have used our research since 2012.

What do I think about the stability of the solution?

Due to the multitude of configuration options, you can occasionally experience compatibility issues with 3rd party storage vendors such as NetApp which recently had a known issue with NFS reporting all ports down.

What do I think about the scalability of the solution?

Never encountered any scalability issues with this product. It is truly enterprise.

How are customer service and support?

Customer Service: Good to excellent.Technical Support: Good to Excellent depending on what engineer is assigned to you.

Which solution did I use previously and why did I switch?

I have tried other hypervisor technologies including XenServer, Hyper V, KVM, Parallels and virtual box. They all do the same thing, but ESXi has been doing it better for longer.

How was the initial setup?

Exceedingly simple setup. You can make it more complex depending how truly enterprise your needs are, like stateless implementations of ESXi.

What was our ROI?

Reduced Electricity Bills, reduced hardware and warranty costs. Reduced server implementation time. Increased management and availability of corporate services.

Which other solutions did I evaluate?

Not on this occasion but I have assessed other hypervisors.

What other advice do I have?

Assess why you think virtualisation is the answer to your problem. Research hypervisor choices, perform Proof of Concept exercises with those products you choose to assess and most of all think about the legacy of what you're doing. i.e. what do you want to leave behind?

There will be no performance issues as long as you run the correct no of vm that is supported by the hardware.
Here is a simple calculation to find out the no of vm you can run on your hardware.
A Hard disk with
7,200 rpm - 100 iops
10,000 rpm-150 iops
15,000 rpm- 200 iops
For Example : You have 9 Hard disks configured in Raid ,Count the no of hard disks that contribute to the storage.
In this case all 9 hard disks contribute to the storage.And the hard disk has a 10,000 rpm speed so the no of iops is 150
Hard disk*no of iops=Total no of iops
9*150= 1350
if we would like to run 40 virtual machines
1350/40 = 33.75 each vm would get around 33 iops which would give you no performance issues.
Instead you chose to run 50 vm
1350/50 = 27 each vm would get around 27 iops which would cause performance issues.

vSphere Review

Valuable Features:

- Enterprise class solution - Live Migration (both server and storage) - High Availability and Load Balancing - Disaster Recovery - Lots of 3rd party vendor support - Excellent technical support

Room for Improvement:

- Cost - Lack of support for virtualization (all hypervisors) - Licensing- Started with VMware ESX ver 2.1 in 2004. Currently using vSphere 4.1i and working on upgrade to 5.1 - Chose VMware for several reasons (1) Had experience with Desktop and GSX products (2) Ran on bare metal (3) No other real competitors at the time

Other Advice:

Advice: - VMware is not the only game in town anymore - Look at your requirements: - If you are a small to medium shop other server virtualization products may provide what you need - If you are a large shop I would recommendVMware

When you say a con is lack of virtualization (all hypervisors), can you elaborate?
I have multiple hypervisors running nested on my VMware vSphere environment (works better with 5.5).
Otoh, if you are referring to being able to manage other hypervisors with native vSphere (e.g. client), then fair point as you would have to add the multi hypervisor manager download part of vCenter to be able to do that.
However as you say, many options, Hyper-V is often overlooked or perceived to be expensive as from Microsoft which is not always the case. Likewise there is Xen and KVM among others. From a management perspective you can also do things such as layer OpenStack compute over different hypervisors (e.g. Hyper-V, vSphere/ESXi, KVM, etc). Hence explore your options.

Easily move images of virtual machines between different workspaces and environments
Pros and Cons
  • "The feature that I find very valuable is the ability to move images of virtual machines from different workspaces to other workspaces between different installations."
  • "An area for improvement is that when comparing VMware to Nutanix, Nutanix has higher availability, like clustering for virtual machines. That is a good idea and VMware could profit from something like that for higher availability installations."

What is our primary use case?

We primarily use VMware vSphere for virtualization.

We use it mostly on-premise, but for the last year on cloud.

How has it helped my organization?

It has facilitated the adoption of DevOps practices and technology.

What is most valuable?

The feature that I find very valuable is the ability to move images of virtual machines from different workspaces to other workspaces between different installations.

What needs improvement?

An area for improvement is that when comparing VMware to Nutanix, Nutanix has higher availability, like clustering for virtual machines. That is a good idea and VMware could profit from something like that for higher availability installations.

For how long have I used the solution?

I have been using VMware vSphere for the last eight to 10 years using different scopes for different projects.

What do I think about the stability of the solution?

It is pretty stable.

What do I think about the scalability of the solution?

I haven't had a chance to do any scalability exercises, just some tests, but not on real-time or on real production. Probably later I will get a chance to test scalability.

There are about 10 or 15 people using it directly in the environments and between 500 and 600 people that are enabled with the VMware.

We require just another engineer and myself for the deployment of VMware.

We probably will not increase the licensing for the VMware, but we will increase the load on the installation that is being handled by VMware.

How are customer service and support?

I haven't had a chance yet to use technical support, but from past experience I would say that it's very good. For this project we have not had a chance to use direct technical support, but for previous projects it has been good. So hopefully it stays like that.

How was the initial setup?

The initial setup is relatively simple. Between one and 10, I would give it a six.

For the product that I'm working on right now it took about three weeks because it had several different virtual machines and inside the virtual machines there were a lot of containers. So there were certain complexities that extended the complexity of the VMware installation itself. But for just the VMware only it took about a week and a half or something like that.

We did not use consultants or resellers for deployment, just the documentation.

What's my experience with pricing, setup cost, and licensing?

Our license is on a yearly basis.

What other advice do I have?

My advice to anyone considering using VMware vSphere is you have to find out the requirements. You have to do a very good job finding the requirements so that the scoping and provisioning of the resources are okay. That way you don't have  later have to be constantly changing the configuration. It is good to spend some time doing requirements and finding out the loads, etc... that you are going to have to handle.

Generally, VMware vSphere is not perfect, but it's okay. On a scale of one to ten, I will give it an eight.

You get used to the interface. The pricing is getting cheaper, but it depends. Anyway, it is a good product.

Many good features including stability and reliability; lacks a snapshot feature
Pros and Cons
  • "Has many good features, and is stable and reliable."
  • "It lacks a snapshot feature."

What is our primary use case?

We have a partnership with VMware and I'm the professional service team lead. 

What is most valuable?

VMware has many good features, is stable and reliable. 

What needs improvement?

I'd like to see the snapshot feature that Nutanix has in their product. It takes a snapshot as a backup without processing as a third-party product. I'd like to see that backup feature in VMware.

For how long have I used the solution?

We've been using this solution for seven years. 

What do I think about the stability of the solution?

The solution is stable. 

What do I think about the scalability of the solution?

The solution is scalable.

How are customer service and support?

We're not very satisfied with the customer support. Sometimes I open a ticket and get a remote appointment with one of our customers and most of the time they're not there and I can't contact them. 

How was the initial setup?

The initial setup is pretty easy and took us a couple of days. We check that the hardware is compatible, then we update the firmware and set up an IP address and then test and tune it. Most of our clients are smaller sized companies. 

What other advice do I have?

This is generally a good and stable solution. It's about weighing up the cost against what the product offers for a specific use case. 

I rate this solution seven out of 10. 

Which deployment model are you using for this solution?

Useful management tools, scalable, and stable
Pros and Cons
  • "VMware vSphere has useful tools for management and support."
  • "We have had some problems setting up the monitoring with vSphere. The process could be simplified."

What is our primary use case?

We are using VMware vSphere for our internal management systems. Additionally, we are running the Acronis backup solution, which is partly running on vSphere.

What is most valuable?

VMware vSphere has useful tools for management and support.

What needs improvement?

We have had some problems setting up the monitoring with vSphere. The process could be simplified.

For how long have I used the solution?

I have been using VMware vSphere for approximately two years.

What do I think about the stability of the solution?

VMware vSphere is stable.

What do I think about the scalability of the solution?

The scalability of VMware vSphere has been very good for what we use it for.

Versatile, extremely stable, and very scalable with useful DRS and resource pooling features
Pros and Cons
  • "It is very versatile. All features are beneficial and very good, especially DRS and resource pooling."
  • "They can maybe review its price. They can also consider offering a free public version for development for a certain number of users."

What is our primary use case?

We use it for the virtualization of server infrastructure.

What is most valuable?

It is very versatile. All features are beneficial and very good, especially DRS and resource pooling.

What needs improvement?

They can maybe review its price. They can also consider offering a free public version for development for a certain number of users. 

I am using version 6.7, and it would be good if it has support for SaaS storage. They might already have this feature in the latest version 7.1.

For how long have I used the solution?

We have been using this solution in our company for 10 years.

What do I think about the stability of the solution?

It is extremely stable.

What do I think about the scalability of the solution?

It is very scalable. Its usage depends on each customer. We have small, medium, and large customers. 

As a company, we are not a big consumer of VMware solutions. We do VMware deployments in other companies. We sell it to other companies, and we have a partnership with VMware. 

How are customer service and technical support?

Based on my experience, they are very good. Their support used to be best, but it also depends on the number of subscriptions for each contract. Generally, their process is very good.

How was the initial setup?

It is easy.

What's my experience with pricing, setup cost, and licensing?

I'm not a pricing or budgeting person, but I know that its price is a little bit high, and they can consider reviewing it. Its price is probably the highest in this domain.

What other advice do I have?

I personally do not recommend Hyper-V based on my experience, but I can recommend others to also look at Proxmox. There is also a solution from IBM. They are, for sure, very good contenders.

I would rate VMware vSphere a nine out of 10. It satisfies our needs.

A transparent and independent solution
Pros and Cons
  • "It's very transparent and independent."
  • "The management could be simplified for base-level customers, but of course, it would be difficult to match all customer needs."

What is our primary use case?

Our deployments were formerly on-prem, but we have the role of a cloud provider. We have a distributed solution in our data center and several international cloud providers.

We use VMware vSphere for most of our business processes, including HR. 

What is most valuable?

We like a lot of the features, but none really stand out. It's very transparent and independent. 

What needs improvement?

We are very close to VM, all of our pain-points involve direct discussions. There are no special pain-points. This solution allows us to handle our system. It's required in business processes.

The management could be simplified for base-level customers, but of course, it would be difficult to match all customer needs. 

For how long have I used the solution?

We have been using VMware vSphere for over 20 years.

What do I think about the stability of the solution?

VMware vSphere is absolutely stable.

What do I think about the scalability of the solution?

We expand VMware vSphere daily. It's very scalable. 

How are customer service and technical support?

The technical support is great. 

How was the initial setup?

The initial setup is straightforward. The complexities lie on the TITO solution on-top.

What's my experience with pricing, setup cost, and licensing?

The price could always be lower, but I think it's fair. 

What other advice do I have?

I would absolutely recommend using this solution. It's clear-based, straightforward, and includes all of the options required in business. 

Overall, on a scale from one to ten, I would give this solution a rating of ten.
