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.

• Ease of use - we don't want to spend extra hours trying to figure out a problem.
• Easy Setup - onboarding was simple and quick.
• Great documentation - Most of the answers to our questions are very easily accessible without additional help.

Incentivized

• Creating VMS - virtualizing physical or already virtual images is a snap
• Configuration - in a smaller environment, configuration is simple and easy to understand
• Templates and Clones - the ability to create these on the fly make it great for a dev environment

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• Documentation is out of date and incorrect for the most part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

• 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.

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.

Everything is very clearly laid out. Being familiar with vSphere already, it was a quick transition over to the IBM environment. This allowed us to spend less time on the implementation phase and move quickly to actually utilizing the system on a day to day basis. Also, the performance is very good. No lagginess to the website like our previous on-prem environment.

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!

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.

We chose VMware over Azure App Service because of the way that it was at that point natural and still offered similar cloud capacities that Azure would have acquired us. This permitted us to continue to utilize a similar interface and not need to relearn everything beginning to end with another item.

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.

• One of our business objectives was to ensure as close to 100% uptime of our servers and applications. This solution has helped us achieve that goal.
• Another goal was to try and minimize our datacenter footprint. This was achieved by using the product.

• 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.
