Citrix Hypervisor

XenServer is well suited for all scenarios for deployment for a modern infrastructure. The weak link it has is of course for classic physical hardware that has key fobs or other telephony cards which aren't properly supported in a virtualized environment. Even if you have one physical server, virtualizing is the best practice to do.

Nutanix [AOS] is well-suited for virtualized environments requiring high performance computing with the flexibility to scale and grow the environment well into the future. The applications that can run on Nutanix is typically your business critical applications such ERP, CRM, BI, Microsoft Exchange On-premise, etc. If your application can run in a virtualized environment, it can then most likely run on Nutanix [AOS]. If you business requires an intelligent virtualized platform with insight into how the underlying infrastructure is performing, then Nutanix [AOS] has very good management tools which can provide these type of reports.

Pros

Citrix Hypervisor

  • Manages upgrades to the pool of hypervisor hosts with relative ease through a console (if licensed).
  • Makes it easy to create machine templates and clones and move them around within the pool of hosts.
  • Handles failures reasonably well through the use of the pool database copied on each host

  • One component to support both compute and storage needs for virtualization.
  • Easy expandable as business needs arise both at the node level and larger with blocks.
  • Well outlined interface with good historical data.
  • API tools are available to obtain logging information from Nutanix that can be used with other monitoring tools such as Splunk.

Cons

Citrix Hypervisor

  • Support - if free is what you need, great support is not what you'll get, keep in mind if support is necessary
  • Upgrades - the upgrade process is buggy and problematic at best
  • Partner Support - if you're looking for a product with multiple parters rolled in, I'd look elsewhere

  • Can be priced high at times.
  • The one downside I have working with Nutanix is the sales team. They seem to try to add in extra goodies to sales quotes or push for extras that you don't really need and you have to tell them to take them out. Don't be afraid to push back on them.
  • Need to analyze sizing with sales team to ensure right sizing.

With the knowledge and usage of solutions from VMware and Microsoft offering more compelling cloud integrated options it makes it more compelling in many environments which I consult. XenServer is a good product and fits the bill in many smaller environments but as clients look to the cloud or a hybrid cloud it can in some cases make it a bit more difficult.

We made a huge financial investment with this platform (four clusters, all-flash storage array), so we're in it for the long haul. Luckily it's a beast. I've had to use support more than any other platform I've administered, but the help has been very good. Nutanix continues to add features and innovations which increase the ROI

XenServer is quite usable due to the simplicity the management and installation provide for an administrator. The console for management is very intuitive and can easily be installed on any Windows operating system. There is a relatively simple web console that can be implemented as well that enhances the usability to provide service to non-administrators.

While you are going to have to comfortable with CLI to perform a lot of functions, the truth is most of the day-to-day work is done right through the web interface. That's one area that has improved a lot in the two years I've had it: how much can be done through the browser as opposed to the command line. And I still would like to see the system better documented. The articles often seem to presume a high level of knowledge about the system, making it difficult sometimes to complete tasks that I would like to be able to perform without contacting tech support.

It's been a little problematic in the past at larger VDI deployments requiring a bit more care and feeding than other vendors. But the latest releases (6.5.x) have brought about huge improvements in the stability and availability.

When running like a top XenServer is a fantastic hypervisor. There is relatively low overhead on the Dom0 so workloads get the most of the resources.

Most are very good, performance is good. But some of the pre-build VMs took a longer time to boot up. Sometimes, we transfer data from one VM to another VM, it is actually bit slower than we expected. Other than those, we do not have other challeges.

Anytime I had to request support from the Citrix Hypervisor website I had an instant answer and it was straight to the point. I also used the forums available to everyone and always had success from both the technical staff and from the community.

At Nutanix, support is one of their strongest points. Probably the best support I've worked with (EMC, HP, DELL, IBM, Netapp). Please note that most of these companies utilize third-party/partners for support in Brazil, so it's possible they have better support in other regions, especially USA.

Part of a training for certification to become a trainer for Citrix included an in-person training with a Master CCI. The XenServer training at this time was pretty simplified due to the product primarily being installed however you did have to work with it and mildly configure the system.

Haven't given it a real go with any online training however there are some options out there. I have taught a course following Citrix material for XenDesktop which leverages XenServer and it is pre-built so not the best for XenServer specifically for installation but configuration is mildly touched on

Ensure you review the HCL (hardware compatibility list) and reach out to the hardware vendors to ensure they support the platform and in case they have documentation that can be followed for the implementation. Also ensure the prerequisites are completed prior to implementation so that as few unexpected delays occur as you can control.

IPv6 is needed for link local discovery. We do not have IPv6 configured on our network so the easiest way to get our nodes configured and discovered by foundation was to configure the IPv4 addressing within the node prior to trying to discover with foundation.

Alternatives Considered

Citrix Hypervisor

The price is very good. Also, the support from the vendor in the process of implementation and maintenance is very important. Citrix offers this support. The implementation was easy, and gave us the ability to manage a large virtual infrastructure while reducing costs. The virtualization solution from Citrix offers more than other solutions had. Citrix is the best!

We looked at both Simplivity and Cisco HyperFlex. Both are pretty good in their own right. Simplivity was very 'efficient' in the way they handled data, but we didn't like the idea of a propitiatory hardware card. Cisco's HyperFlex was our second choice, but we were so impressed with what Nutanix had done for us already, that we were already leaning toward that.

Scalability

Based on 1 answer
The servers latest versions have made massive improvements to scalability. But from past experience there have been issues when running workloads for extended periods of time without reboot on the hosts. I would need to run similar workloads on the 6.5 release which has changed much of the bottlenecks or issues so I'd imagine its far more capable now, Perhaps able to stand near the best in the market.

Return on Investment

Citrix Hypervisor

  • We noticed a true ROI within the first 2 years of implementation. The longer hardware refresh cycles save organizations like ours a lot of money each year.

  • Found an immediate reclamation of time. SAN's are a pain to manage and update - Nutanix made turned a couple hours of work into one click.
  • They are a software company. Every Time they come out with an update I find my performance improving, or a new feature added. Soon I'll be able to give my developers controlled self-service capabilities. I originally bought hardware and it's evolving on me into a private cloud in a box.
