VMware vSphere Review

High Availability works with a series of sub-features that ensure customer resources are online during critical changes.

What is most valuable?

vSphere has many great features. It is very hard choose just one because most of them work together. But, based on the way how vSphere manages all resources provided by the physical system, I believe that the high availability system is the greatest feature of the solution. It works with a series of sub-features that ensure customer resources are online during critical changes.

How has it helped my organization?

We are constantly updating and migrating systems here in my current company. With this product, we can run parallel systems with a low cost and without impacting our customers. With this solution, we can provide more resources, cheaper, quickly, and still keep the integrity and quality of our services.

What needs improvement?

This product already does this very well, but all improvements are related to how physical resources, as well as memory and CPU, are managed . These are the main problems of the virtualization, it uses more memory than CPU. We still have problems with memory in virtualization environments, and some cases can present problems of throughput with virtual disks, too.

For how long have I used the solution?

I have been working directly with vSphere solution for about four years, but I work with virtualization about six years.

What do I think about the stability of the solution?

This solution is very stable. Hardly ever do critical issues appear in the environment, and most analyses that are done in the system are about performance improvements.

What do I think about the scalability of the solution?

No, this solution is prepared to expand or decrease as necessary.

How are customer service and technical support?

Customer Service:

It is great. They really have a good service.

Technical Support:

The support service is very efficient. They are fast and usually they have a great technical knowledge beyond an effort to solve your problem.

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

I work with more than one virtualization technology. The solution implemented varies according to client requests.

How was the initial setup?

The implementation of the solution is relatively simple. Of course, you need to have some knowledge about infrastructure to be able to create an environment without performance issues. But in general, the deployment of the vSphere system is easy. Just some feature configurations need to be really studied to improve if they really have to be implemented. VMWare provides all the documentation necessary to implement and manage vSphere throughout your environment.

The most common problem in implementing this solution is the incompatibility with some physical hardware, but it was more frequent in the past. All current physical hardware can support virtualization technology.

What about the implementation team?

The implementation was done in-house.

What was our ROI?

This solution is recommended for environments considered medium and above (in the number of servers and hosts). If you are intending deploy this solution to small environments, the cost-benefit is not worth it. VMware provides a free license to be put in small environments, but all the good features of the systems will be disabled. For smaller businesses, I would recommend another solution.

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

As prices vary, the ideal would be to contact a direct sales team, and report the company's needs so they can point out the best license to use.

Which other solutions did I evaluate?

As I said, I work with more than one virtualization technologies. Beyond VMWare vSphere, I've worked with Microsoft Hyper-V, which is a great virtualization solution too.

What other advice do I have?

It is necessary to be sure about the systems that will be migrated to a virtualized environment. Although nowadays virtualization is at an advanced stage, some systems still present problems when they are migrated from a physical server to a virtualized one. Systems that require too much performance need to have a different configuration, then it's a necessary study on how to implement them.

Which version of this solution are you currently using?

5.0, 5.5, and 6.0
