Scale Computing Platform vs. XenServer

Scale is best suited to environments that do not have excessive external or proprietary peripherals. Integrating with tape drive backups or robot tape libraries can be problematic. The most effective use of Scale systems is for companies running multiple instances of the same operating system. The hypervisor's code/file-sharing nature does an excellent job managing new instances while keeping the increase in storage to a minimum.

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.

• Simplicity - I do not have to create storage buckets or micromanage anything.
• Efficiency - Lower power use since moving to a hyperconverged environment.
• Scalability - Adding additional hardware is easy, and increasing things like the amount of RAM or number of cores is easy.

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

• Display the IP address of the node on which the VM is running on the Devices (gear icon) tab. This would allow me to manage my Microsoft license easier.
• During the on-boarding I missed the step to install the Scale Computing Platform tools, and we didn't notice this until I had issues with backups. It would be helpful if some kind of alert notification would display on a VM card if the tools were not installed.
• Add a new health or diagnostics tab that would display alerts, diagnostic tools, performance concerns or pattern anomalies.
• Some kind of email/alert when a disk reaches near capacity

Incentivized

• 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.

I'm on the fence about renewing the support contract. The reliability of the HC3 makes it difficult to spend the cost of the renewal which is higher than the costs prior to Scale. I'm convinced if we were a larger district that the savings would be tremendous and I wouldn't hesitate to renew. In our specific situation, it may be more feasible to pay per incident.

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 you need to do is point-and-click easy. If you are the kind of admin who wants to edit every config file and endlessly customize your environment, then Scale may not be for you. On the other hand, if you just want it to work really well, and do what they told you it will do, then Scale is the ideal system.

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.

Never had an outage or an error. Once a hard drive failed, but Scale kept on working flawlessly without interruption.

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.

Incentivized

Performance has been just as outstanding as reliability. I have never experienced delays in any aspect of usage.

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.

We had one need for support post-setup, and the person who answered the phone was the support person I needed. No transfer, no level one, and our accents were similar enough that we understood each other easily. The problem was actually in my switch, not with Scale, but the support person still assisted me and got the entire cluster up and running again in under 30 minutes. They are truly a partner not just a vendor.

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.

I did not do in-person training.

Incentivized

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

Because Scale is so simple, the training is just as quick and easy.

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

The implementation was very easy. We had Scale support on standby and they were ready and eager to help if needed. The process went so fast the employees in the organization did not even know it was done.

Incentivized

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.

As mentioned previously, not having to worry about the compatibility between your hardware, hypervisor, and VM OS is a great help. On the downside, there is less ability to get deep in the weeds with your own system. Much of the Scale HyperCore OS is locked down intentionally, which prevents technical users from having much insight on broad error messages without support intervention.

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.

HC3 is one of the best products I have purchased for our district. It is unbelievably reliable to the point that they shoot themselves in the foot on support contracts.

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.

• With the high cost of the leading competitor the savings starts day one and saves every year after.
• Scale can be administered by a tier one technician so cost of labor is reduced.
• If there is a problem like a cyber attack, the savings kick in with the least amount of downtime.

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.
