Cisco HyperFlex Systems is a hyper-converged infrastructure product, based on technology acquired with SpringPath (acquired September 2017).

A bare-metal hypervisor that installs directly onto a physical server. With direct access to and control of underlying resources, VMware ESXi partitions hardware to consolidate applications and cut costs.
Cisco was selected due to more favorable financing. HPE financing was more difficult to obtain. Hyperflex is very different from other solutions - highly redundant with a fast backplane, but many techs are not familiar with the solution and typically prefer the more traditional …
Hyperflex is that it is a simplified product that assists in the storage of software data and also provides an infrastructure for data optimization and network management quickly and efficiently.
Smaller sites that would benefit from a cluster of 2-5 nodes. Not saying that it can't scale above that, but I find HyperFlex a great solution for those sites. A simple 3-node edge cluster can provide a huge amount of resources and redundancy. It's also really easy to scale the environment to meet growth requirements.
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!
UCS manager in HX is truly helping us in doing one touch firmware upgrades. Scaling of HX cluster (in few minutes) is too seamlessly due to service profiles.
HX does not hold you back by creating a single data store unlike other HCI products. With HX, you can create multiple data stores and allocate those to desired services. This help logically separate the install base on HX and removes confusion for the admins too.
We run high IOPs workload on HX, and we never felt latency issues due to the Cisco backbone (as you get FI as a TOR switch and options to choose 10G or 40G speeds).
With HX you truly enjoy a single window support from Cisco including for the top of the rack switch (FI in HX case). In other HCI infra, you certainly have to bank on to network switch vendor for support and bring HCI and switch vendor at one pane for troubleshooting latency related issues.
While we increased our footprint on HX, we didn't added additional administrators to support the landscape. This was possible because of the simplicity in managing HX clusters.
With HX we had setup stretched cluster between two near site data centres. This is a unique proposition in HX (we have 2 nodes in each data centre) and data centre failover works absolutely seamless.
Resource management. The automatic load balancing works very well to ensure no host is taxed disproportionately compared to the others.
Templates and cloning. It is very easy to set up a template and spin up new servers based on a specific setup. This makes server management very streamlined.
VM management. The vSphere interface is very easy to use and navigate. Everything is responsive and it works when you need it to. The options are also robust while also being arranged in a straightforward manner.
there is the problem with starting cluster where there are not outside DNS and NTP services so we need to workaround this with additional storage or hosting it on the local storage.. many clusters has internal DNS/NTP services not available from outside and they need to be hosted on the HX
there is not RBAC or user mgmt on the CVMs so it is difficult to not add full permission for the people responsible for just shutdown and power on the cluster
native snapshots support with ibm backup products
running from not the only last snapshot in all use cases
VMware ESXi can improve on the UI that is installed on the bare metal machine. The menus can be hard to navigate when looking for simple configuration items.
VMware ESXi can improve on the stability of their overall hypervisor. There have been a few times we had to reinstall due to corruption of VMware ESXi.
I would like to see VMware ESXi do better at adding more standard free features in their consumer version of VMware ESXi. For example, having the ability to back up virtual machines is good practice and something that would be very nice if offered in their free version.
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.
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.
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.
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.
More documentation is available now than when the product initially came out (which was an issue early on). Because it only supports UCS hardware, I think it does help with support issues. Nutanix has to support much more hardware. At the same time, you're dealing with the Cisco TAC, which can be mixed at times.
I can't say enough good about VMware's support team. To an individual they take ownership of the case, provide thorough answers, and follow up regularly. On one occasion, a problem we experienced with NSX Endpoint was escalated to development for a permanent resolution after a workaround was found. In my experience, most companies would have tried to find a way to close a case like that instead of taking it all the way. Most importantly, when production is down and every second counts, they VMware teams understand that urgency and treat your issue as if it were the only one they had to deal with. You can't ask for better.
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.
HyperFlex is built on top of Cisco UCS infrastructure, which allows us to manage other non-HX servers attached to the same UCS environment. This allows us to tie everything together via Intersight and see all of the servers in our data centers. Other platforms don't really have a comparable offering.
As long as you're using Nutanix AOS on Nutanix hardware and are paying their software support fees, AOS is a valid competitor to VMware and can save money due to not needing a license and having their server management system built into the base host management system. If you aren't using Nutanix hardware, however, VMWare is in most cases the best way to go. I cannot comment on HyperV, but most IT people I know either use it because they have to (most) or they like it better (not many).
it has been fair and easy to understand. I know VMware is looking at wanting to change from CPU to core pricing so we will see what that looks like when it happens.
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
The simplified management makes it easier to operate and prevents mistakes.
Guided installation using the installer VM means you don't have to configure every component by hand. Improves deployment speed and lowers the risk of configuration issues.
Performance increase of 40-90% compared to our previous compute/storage cluster.
VMWare ESXi licensing is affordable for our business - and the licensing model is simplistic. Not like that of Microsoft with having to keep track of server licenses and CAL licenses for users.
VMWare ESXi also has hardware-monitoring built-in, so that further saves us money from having to be spent with another vendor.
As much as I hate the saying "a single pane of glass" does fit for this product. You can manage your servers, monitor hardware status, create and export backup snapshots, manage virtual NICs, connect to various storage devices. We're very happy with this product.
