VMware vSphere Review

It is very easy to get things working and it is more difficult to get things working smoothly

Valuable Features

Stability of the Hypervisor, DRS, and HA are some of the more valuable features.

Improvements to My Organization

VMWare (and any virtualization platform) completely changes the way an organization functions. The way you investment in hardware is done from a completely different perspective, in that an initial capital investment is required, and the resources would then be available for the organizations' use.

This, of course, allowed the organization to have a ton of flexibility in resource availability. We were then able to create and build high availability across deployed hardware that would've otherwise been much more complex to accomplish using more traditional methods.

Room for Improvement

Nothing I can think of. For a while, allowing for HA without shared storage was a missing feature, but as of 5.1, VMware introduced that feature.

Use of Solution

I have used vSphere v4.0/5.0/5.1 alongside vCenter v5.1, and VMware Vieew v4.0 and v5.2.

Deployment Issues

There is a lot of know how required to deploy VMWare correctly, especially if it is being architectured to be highly available. A simple deployment is not too hard, but the issues that I had faced initially were mostly related to adequate shared storage connectivity, etc.

Stability Issues

As mentioned above, the stability issues have been caused mostly by the inadequacy of the storage (90% of problems have been related storage).

Scalability Issues

Not at all. Scalability is one of VMware strengths. Running out of resources has really never been an issue, as it is easy to add new hardware, and/or storage, and expand existing infrastructure.

Customer Service and Technical Support

Customer Service:

Customer service has always been available, in a more or less adequate time. VMware is good at responding at critical issues that have a high business impact, though sometimes I had experience less than stellar experience in slightly less urgent issues. This is mostly referring to the timeliness of service. Getting the help needed after getting in touch with support has never been an issue.

Technical Support:

The support is usually pretty good. VMware support is good at making an effort to resolve the problem on first contact, and escalate as necessary. I have always received a solution to my problem.

Previous Solutions

For an enterprise virtualization platform, I have only used VMware. I have also used Amazon Web Services as an IaaS, but that doesn't exactly sit in the same category as an on premises virtualization platform.

Initial Setup

As mentioned above, a simple setup is not hard. However, there are lot of intricacies to the product to set it up correctly with shared storage, so that fail over can function correctly, and DRS, HA, and vMotion to function efficiently.

Implementation Team

I initially did the implementation on my own, with some help from VMware on best practices. I did get some help in getting my enterprise storage installed, and got some guidance from them to fine tune configuration of VMware vSwitches, to achieve optimal performance.


The ROI on virtualization platform isn't always necessarily completely obvious at first glance, as the initial cost to implement it is typically fairly high. However, keeping in mind the soft costs, it would easily prove to be more economical than traditional solutions. Not only that, but it also will require less engineers to manage the system, as all the management tools are built-in within vCenter, to create a unified solution that would ultimately reduce management cost.

Pricing, Setup Cost and Licensing

The original cost of the first set of servers to migrate a whole school district to, was close to $100,000. More recently, an upgrade to an SSD SAN cost an additional $120,000. Keeping in mind software costs of maintaining the product, and all virtualized servers, the day to day cost of the product is essentially the cost of running the hosts, (power, cooling, etc).

Other Solutions Considered

No. I had started with VMware very early on, and adopted it when it became a viable enterprise product.

Other Advice

For anyone looking to implement VMware, don't take the initial implementation lightly, and don't cheapen up on the hardware, especially the storage. You will save a ton of headaches by investing in good storage that would be adequate for at least three years.

Also, do your homework on best practices, and how to implement things. It is very easy to get things working and it is more difficult to get things working smoothly. Never had I thought that I had to get familiar with the deep workings of disks, and IOPs, read and write/s ... but these are really necessary if a good implementation is the goal.

This is a great article and as stated know your stuff when implementing to save time in the long run and configuration nightmares.
