IBM Cloud for VMware Solutions vs. XenServer

VMware Cloud Foundation for Disaster Recovery environment, when the client needs to deploy a pay-as-you-go service or if they need to migrate SAP workloads, you can use VMware Cloud Foundation for Classic and VPC. We are the unique SAP-Certified VMware cloud service provider.

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.

• Adaptable valuing relying upon size and scale.
• The presentation is first rate. Our on-prem climate was continually experiencing slack and general languor. With IBM running everything, it's much smoother.
• Start another group as little as one ESXi worker or scale a current bunch.

Incentivized

• Citrix hypervisor does price very well for small organizations. It is free.
• Since this product is open source it does not have any type of vendor lockdown issues.
• Allows live migration of VM's so you can keep systems up and running when changes are needed to the hardware in the background.
• The GUI management tools are quite easy to learn.
• Has Snapshot capability which is a great way to protect against malware as well as do risk-free upgrades.

Incentivized

• Support is horrible and or non-existent
• Documentation is out of date and incorrect for the most part
• IBM employees and salespeople are not aware of features or offerings
• Does not integrate the Zerto, only Veeam and has limited options for data migration

Incentivized

• Adding or presenting additional storage to the host can often be a task that is far more involved than competitive products.
• The product can require reboots more frequently than competitors due to the DOM kernel getting "hung up".
• Sometimes when a virtual machine is deleted it still leaves behind orphaned vdisks.
• Recovering from the loss of a host can sometimes cause virtual machines to require lengthy command prompt scripting to fix so they can be powered back on from another host.

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.

It is easy to use and setting it up is simple. The only con is that the pricing is a little bit high as well as documentation is a little low; so we had to do some personal learning to be able to fully utilize the product, or hop on the phone with someone.

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.

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.

Overall, just a great experience here. No one in my opinion gets a perfect 10/10 rating (no one is ever perfect), so 9/10 is probably as good as it gets! From initial planning to post implementation support, the IBM Cloud and professional services has been there for my group as much as we have needed them. Great job!

Incentivized

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.

Incentivized

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

IBM professional services helped us plan and implement the project with great success. They guided the project from planning, scoping, pre-implementation, testing, roll-out, then production and post-production support. We were very impressed with their knowledge of VMware and really appreciated their desire to make our project a success. I would highly recommend them!

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.

IBM Cloud for VMware Solutions stacks up against them, we fully agree there are so many features in IBM cloud for VMware Solutions that make it unique and different. The system provides us hypervisor security level and the system even has live backup and storage capacity of data. This system provides us with accuracy that helps us to reduce errors and vulnerability.

Feature for feature they are neck and neck. I have used Hyper-V 2012 and 2016, VMware ESXi and XenServer evenly. XenServer is a fast install, good documentation, with enterprise features out the box that compare or exceed what VMWare offered with a higher cost of entry.

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.

• It has a positive impact on the cost required to maintain our vSphere environment by allowing us to get rid of our vsphere hardware and not worry about maintenance either.
• There have been very few negatives, but one would definitely be the open-ended cost associated with cloud products in general.

Incentivized

• 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.
