Server Virtualization
Comparison of Server Virtualization features of Product A and Product B
We have used these servers as edge servers as well as core servers. They always perform extremely well and have very few hardware issues. If they do experience a hardware issue it is easy to find the replacement part and fix it without any issues. They are great performers and overall a great buy.
If you're looking for the industry standard in server virtualization, I would recommend ESXi. After decades of expertise in the field, VMware continues to provide a strong product, production-ready, with an easy-to-learn interface that allows for quick management along with less costly upfront onboarding and training. Grab the free personal-use license and install in your homelab to start!
It's very customizable. It's customizable as in you have a chassis, but you could pick and choose the size of your blades puff with full width depending on what your workloads are. So in a way, you're not locked in. It's not like you buy a chassis and you're stuck into one thing could go and put, you need something that's storage intensive or maybe you've got more graphics intensive workload. You could choose and mix and match in the same.
There are some odd issues with VMware's virtualized network drive (VMXNET3). On occasion, after a reboot of a Windows-based VM the NIC will fail to bind properly and network access is unavailable until an admin intervenes by disabling/re-enabling the adapter. While it's possible that our environment is a contributing factor, this never happens on VMs using Intel E1000 emulation, only the paravirtual NICs.
Logging is extensive but difficult to work with. VMware's solution is a product called Log Insight, which comes at additional cost. Fortunately this is somewhat mitigated by the extensive support documentation and robust user community, but in the heat of the moment obtaining the required detail can be a trying experience.
Cisco UCS has been a highly reliable compute platform for our workloads, handling MSSQL, SSIS, virtualization (VMware vSphere), and analytics workloads with low latency and high efficiency. UCS Service Profiles and centralized management (UCS Manager, Intersight) make it easy to provision, scale, and manage compute resources efficiently across production and non-production environments. Our UCS setup integrates well with Pure Storage and Nimble HF40, delivering high IOPS, low latency, and fast throughput for data-intensive workloads. Cisco UCS hardware and licensing can be expensive compared to some alternative compute platforms, especially when considering cloud-based or hyperconverged options. While UCS can work in a hybrid cloud setup, it doesn’t natively integrate as seamlessly with public cloud providers like Azure or AWS compared to some newer solutions. We may need to evaluate Azure Stack HCI or AWS Outposts for future flexibility.
It is critical to our business, what started out as a way to do certain functions, it has now become core to ensuring our product is available to our customers and reducing our costs to operate and reduce our recovery time and provisioning servers. Their support is great and the costs to renew is reasonable.
While Cisco's hardware is solid and long running, their software is usually the weak point. I will say that they are getting better with each release but if I had to find a problem with usability that would be it. Overall usability is good when you can work around software issues.
The interface is fairly intuitive for most things, and the areas that are a little less obvious usually have fantastic documentation in the online knowledgebase. In 3-4 years of managing our ESXi hosts, I think that I have only opened 4-5 support cases for things that I could not figure out myself or find answers to on the website.
The platform’s redundant fabric interconnects, power supplies, and built-in high-availability features ensure that systems remain online even during hardware failures or maintenance. Unplanned outages are rare, and when combined with proactive monitoring, UCS provides a very reliable environment for critical workloads.
Without the need to patch the servers with bug fixes and enhancements we whave not experienced any downtime with VMware issues. Even the bug fixes and updates do not cause of downtime as we just migrate the servers to the opposite node and update the one and then move servers back. Very simple and painless.
The platform delivers fast and consistent compute performance for a wide range of workloads, including virtualization, and high-throughput applications. Even when integrated with other systems or software, UCS maintains responsiveness, ensuring reports, applications, and services run efficiently without noticeable slowdowns.
We do not notice any difference between a physical and virtual server running the same workload. In fact we can scale quicker with the virtual server than we can with the physical.
Cisco TAC is simply unbeatable and that goes for Cisco UCS server support just as well as it does for Cisco CUCM software. TAC has a well-deserved, excellent reputation and I do not hesitate to call them or open a ticket online, because I always know that I will get the help that I need and get it quickly
I rarely ever need support for anything VMWare makes, but when I do, the documentation available just in the free community is generally enough. It's extensive and the community is truly robust and active. And if you have a myvmware account, you can get support for your owned products from VMWare support by the conventional case/ticket method
I would rate the in-person training as excellent. The sessions were well-structured, hands-on, and delivered by knowledgeable instructors who made UCS concepts easy to understand. It greatly improved our team’s confidence in managing the platform.
The training materials provided were generally informative and covered the essential aspects of the UCS platform, such as UCS Manager, Service Profiles, and integration with other systems. However, some of the training modules could benefit from being more hands-on and interactive. Additionally, certain advanced topics, like complex network configurations or troubleshooting hardware issues, were not covered in as much depth. Overall, while the training was useful, there’s room for improvement in terms of depth and practical application for more advanced users.
While there were some challenges, particularly with driver compatibility, network configuration, and hardware integration, the overall process was well-managed. The implementation team worked effectively to resolve issues, and we received great support from Cisco throughout the process. The training and knowledge gaps were addressed, and once the system was up and running, the UCS Series has significantly improved our infrastructure. The experience was generally positive, and any difficulties encountered were ultimately overcome with careful planning and support.
Jsut read and follow anything your storage provider may require to allow the integration of VMware with storage operations, outside of that VMware jsut works.
UCS integrates with VMware vSphere while adding hardware automation and unified fabric. Why UCS? Cisco UCS offers better infrastructure abstraction and automation via UCS Manager and Intersight. The integration of compute and fabric in a single system reduced configuration time and enabled faster troubleshooting. We selected Cisco UCS because it aligns with our long-term strategy, offering infrastructure, simplified lifecycle management, automated scaling, and reduced operational complexity. Additionally, we secured a significant discount from Cisco due to our use of another Cisco solution.
While Hyper-V also can work very well and can have licensing benefits, it does rely on Windows in order to run. This isn't necessarily a bad thing, but it can add another layer of potential failure and might not be running on as low of a level as ESXi does. The footprint for Hyper-V can be smaller if the Desktop Experience isn't used for the hosts, but this is the default fashion that ESXi has been running for many years. VMware's support has always been stellar, and its documentation is phenomenal. Hyper-V can work as a virtual environment option, but ESXi has never let me down in any environment I have managed. I will continue standing by this product and prefer it over other options. It has proven itself time and time again over time as the defacto virtual environment hosting platform.
Cisco UCS Series provides a highly flexible architecture with service profiles, fabric interconnects, and modular blades/rack servers, allowing organizations to scale compute and network resources across multiple departments and sites efficiently. The only minor limitation is that careful planning is required to maintain consistency at very large scales.
We started out with a two-server cluster and adding a third or fourth is very straightforward and simple with no issues. You just need to be aware of the size of your Vcenter Server to handle the workload, but still the resources needed is very minimal
Positively, it has saved us time in spinning up new servers for the different departments in our company. It is easy for us to spin up virtual machines with VMware ESXi and deploy applications at the drop of a hat.
Positively we are able to save space in our data closets as we no longer need to keep room for physical servers and workstations, allowing us to expand in other areas like networking equipment and physical backup solutions.
It has moved our business forward as we are able to migrate old servers and static workstations in the virtual environment allowing us to easily keep an eye on older applications and update/backup easily through VMware ESXi management console.
