Running Multiple Hypervisors Under vCenter: A Quick Look At Hotlink

Over the last couple weeks a very common question I am getting from customers is around switching off of VMware and onto another hypervisor. Usually when we go through the exercise to determine if this is something within their comfort zone we find quickly that the idea of rip and replace is much more of a burden than keeping the current infrastructure. But with that said, things are a changing and people are looking at a plan B so they are not married to a specific vendor incase of some sort of dramatic change, lets say pricing or feature set for example.

Until recently I could honestly say there wasn’t any alternatives that we would recommend that was apples to apples in features and scalability etc. Plus, even if a customer moved to a lateral competitor (Citrix or Hyper-v) they same “locked in” situation would occur. Now, only if there was a product that could manage all the different types of hyper-visors with the best of bread management software on a single platform?

Well we are all in luck because there is a new company that promises to help with this situation. Hotlink was founded last year and will be launching their new product, Hotlink SuperVISOR, very soon and I can say looking over their spec sheets that I am excited to see if this will be as advertised!

What Is it exactly:

In its simplest form it is a layer that sits in-between the hypervisor layer and your management console (vCenter for example).  Using their unique tools set including virtual object bus, transformation technology, proxy and integration services it allows for heterogeneous environment. This means, good or bad, you can run a multitude of different hypervisors under one single platform.


One thing that I do like about this technology is that it does take advantage of your best of breed products. For example, its first management plugin is designed for VMware vCenter and looking over the feature set this is a wise decision. Customer familiar with working in this management console will find the transition smooth with little to no disruption allowing them to leverage existing skills.

As well, you can now mix and match your hypervisors to match your application needs. This both increases efficiency and decreases cost as you put enterprise class programs on VMWare which is expensive and put tier 3 applications on Hyper-v which is less expensive. This puts you in a position to avoid vendor lock-in and if you are already running multiple hypervisors provide a single management console reducing your opex.


I want to be careful when pointing out good vs. bad when reviewing this product because to be transparent I haven’t seen a demo copy or tested it in the lab as of yet. So instead I just have a lot of questions about the functionality, performance and other technical details.

For starters, I am not sure on the performance overhead of my host machines? I don’t know what this does to my environment if lets say I structurally built around VMware now running several different products under the same hood? I don’t know how this would affect my storage infrastructure and included API’s from EMC, NetApp, etc? Design, deployment, troubleshooting are all questions at this point. This is just the tip of the iceberg. I will say I would be a bit nervous putting this layer in my environment without a firm understanding of all impacts it would put on my infrastructure.

What it won’t solve:

It still won’t address any licensing issues around cost reduction. True you could say move your file servers to Hyper-v which is free with Windows server licenses and only keep your primary machines under VMware but that falls into the 80/20 principle and willing to bet that most of your production applications are high to mission critical and cannot afford any downtime, which is why people move to VMware and pay the extra premium.  However it could help lead down the path were you could give VMware a solid threat to migrate and have a powerful tool at your disposal.


The base price for the SuperVISOR platform is $25k, which includes support for vSphere + 1 other hypervisor and 5 hosts. That is all the details I have at this point. As I hear more I will update this posting.


Overall this is a great step forward and depending on execution could change the virtualization landscape. I would assume that there will be a group of similar products over the next couple months as this idea gains traction. So I will be curious to see how fast Hotlink can move to market and get adoption going. Looking to seeing more updates.
