VMware vSphere Review

WAN management has some stability issues, but it has given us a substantial increase in server density.


What is most valuable?

  • Virtualization
  • Clustering
  • High Availability
  • All the core functionalities

How has it helped my organization?

Allows for substantial increase in server density, reduced spin up times, allows for more remote site management. Recoverability in a server crash situation is substantially improved as well.

What needs improvement?

User interface and management. The ability to manage the underlying infrastructure is very poorly thought out and implemented. They moved from a C client to a web interface, but still require critical functions to use the client.

For how long have I used the solution?

I've been using it for seven years, since it was ESX v3.5.

What do I think about the stability of the solution?

WAN management of sites has some intermittent stability issues.

How are customer service and technical support?

I would rate it fairly high, as much as I complain about the changes their back end team make, their front end support, and sales guys are very communicative.

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

We used Microsoft Virtual Server before ESX3.5 was released. We switched because it was not an enterprise grade option.

How was the initial setup?

The setup for the current datacenter was complex, not because of VMware but because of the hosting limitations provided.

What about the implementation team?

We had it initially set up by a vendor team, and I spent four months afterwards fixing their work. I would advise that you verify in advance the skills and knowledge of the implementors.

What was our ROI?

No attempt to calculate ROI has been made on the current environment.

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

I am attempting to build an environment around ROBO licensing, which I would advise anyone who has remote offices to investigate. It should cut our costs bytwo-thirds when I am finished.

Which other solutions did I evaluate?

No evaluation was done.

The Web Interface has been really improved in vSphere 6.0 and has become usable.
