Quotes From Members Comparing XenServer vs. vSphere

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
Pros
As an end-user, I would say it has allowed us to have the flexibility of moving around our workloads on different machines, and not having to worry if anything is down.The ability to to virtualize systems and run those virtual workloads with a fewer number of servers is tremendous.I like the capability of logging into one system, then being able to shift over to another system within that single pane of glass.The scalability of the solution is good. You can scale up to maximum levels.The DRS feature of this solution is a very valuable feature.We have seen a tremendous performance boost. From when we started this VMware engagement in 2016 until now, we have seen around a 70 percent performance boost. This is a good number.The built-in encryption of vSphere really helps us to secure our customers, especially customers in the medical field who need to be HIPAA compliant. Being able to encrypt the VM itself helps out a ton.You see more responsiveness, especially now with having the HTML5 client. It feels like a much snappier product.

Cons
In addition, I think some of the backup features or the prediction features can be improved.The one area where I would love to see an improvement is the HTML5 client. It's great, but it could get better.In addition, I think they should come up with a backup feature which is more product enrichment-based. It should be a full-fledged backup solution. It just is not there right now.From my point of view, my advice is to design the solution properly the first time.There is still room for improvement with the HTML5 Web Client. They are working on it, as I can see on their blog. However, there is still room for improvement in the newer features that they can push into it.The biggest issue with stability is the SSO. That is still an issue as far as integrating it with Active Directory, and any large scale of it.The biggest thing to improve is to have more self-service in the portals. I would like to receive more help through the web interface.It is expensive.

Pricing and Cost Advice
I think the cost should be reconsidered. VMware is not the cheapest solution out there, despite the fact that it may be one of the best.I did a comparison between physical server to virtual. There was a point in time where we would size out a virtual server to be a massive size, then we'd buy a physical server of the equivalence. We saved somewhere around 20 percent going virtual, as opposed to the physical equivalent.The pricing is justified. It may be a bit high, but the features are worth it.The pricing is competitive.In the past six months, we have saved around 110TBs of storage, which is almost equivalent to $200,000 USD. That is a huge savings.vSphere is an expensive solution.VSphere is an expensive solution.In today's market, agility is the new currency. Without virtualization, and vSphere in particular, we wouldn't have the level of agility in the business that we have today.
