Comparison of Server Virtualization features of Product A and Product B
[Nutanix AOS] is good when you need easy scaling and high reliability. The good architecture of the solution allows to solve the tasks set for the platform. This solution allows to reduce the number of personnel serving the infrastructure due to the ease of management and a good knowledge base. As a disadvantage, I would attribute the complexity of customizing some types of loads to optimal work on DFS, for example, high-load databases.
It can be really helpful & useful if we are using Citrix Hypervisor with other provisioning tools. Here are some specific scenarios where Citrix Hypervisor (formerly Citrix XenServer) is well-suited: Server Consolidation, Virtual Desktops, Disaster Recovery, Development & Testing Environments. On the other hand, there are some scenarios where Citrix Hypervisor may be less appropriate: Small-scale Deployments, Highly Heterogeneous Environments, and Limited Virtualization Requirements.
Management of VMs on AHV take some getting used to. It's just a list of VMs that are displayed, and you search through it. Not the normal folder structure that I'm used to in VMware.
Also can't disable a NIC card in a VM in AHV. Very handy feature present in VMware.
Larger workloads may have to be tweaked to get the performance you need/want.
Although part of this is free the free solution has limitations that make the purchase of the paid version a requirement for most medium and large enterprises.
Support for USB devices is lacking vs. its competitors.
Technical support is somewhat limited especially the free "Google browsing" type since the product is used much less vs. Hyper-V or VMWARE.
In a related issue to tech support, finding local IT support who have used the product is also challenging.
Networking/virtual networks are less stable than they should be.
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
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.
Nutanix Prism Element and Prism Central are easy-to-use HTML5-based web consoles. The layout makes sense; you're only a few clicks away from getting to where you need to be. The AHV hypervisor is integrated into the platform for a fast and seamless experience. Rich data on VM metrics is also available.
XenServer is a good product in its use and probably free if you have the right Citrix licenses already. However, it does require specific knowledge to manage, which makes it harder to manage if you don't have that knowledge in house.
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.
The performance is very impressive. I am used to VMware and the snapshots were taking 10 minutes. The first time I had to restore from a snapshot on Nutanix it took 5 seconds and I couldn't believe it. Everything done on the server is fast. Powering on VM is done in seconds compared.to what we were using before.
Our first support ticket to Nutanix was responded to within 10 minutes of submission. That was kind of impressive. They have worldwide support so that when a support request is created, support is acknowledged in a relative short amount of time.
The staff I've worked with are very knowledgeable or able to get a very well articulated and capable support team member on the phone or helping them if necessary and they always want to ensure the best experience possible for you on the platform. The ability for the support team to reach out to hardware vendors for assistance is a nice plus too.
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.
By far, in my opinion, Nutanix AOS is heads above VMware. From the creation of a VM to updating the nodes themselves, Nutanix AOS is so much easier, faster, and just an overall better product. I would choose Nutanix AOS over VMware any day.
In the scheme of the real world, Citrix Hypervisor is used much less than the other two main competing products; MS Hyper-V and VMWare vSphere. So, choosing Citrix Hypervisor for your organization comes down to whether you are comfortable going with a lesser-used product. All 3 products offer hardware layered hypervisor installation which means no OS overhead headaches. That is usually positive but in some cases, with very small shops, the OS layer is needed to host other workloads so Hyper-V running on Windows is the better choice. We run both MS Hyper-V and Citrix Hypervisor and we chose the Citrix product for our testbed environment since any risk of running the less public supported product was lessened by not being in full production.
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.
Xenserver is easy to learn. We paid for support only for installation and deployment in the first three years, and now our team has the knowledge to solve most problems.
Low CAPEX if you have a team that uses open source software day by day.
But paid support is necessary to solve critical problems. The open source community is not enough. Actually, we have difficulty solving some bugs without paying for support.
Medium OPEX if you have a team that uses open source software day by day.
