VMware ESXi vs. VMware vSAN

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!

vSAN is well suited for any application that can run in Virtual Environment. vSAN serves better for VDI, NSX, and vSphere on Cloud solutions. vSAN is a good fit for small and medium business companies. vSAN can't be a good solution where you have Oracle Solaris or IBM power systems. vSAN can't provide storage space using FCP protocol.

• Incredibly quick to deploy. Total installation time of less than five minutes
• Able to easily mount ISCSI storage devices to VMWare ESXi hosts within the GUI
• Allows you to run the product for free - if you stay under the physical core count (and with some reduced features)
• Incredibly stable software - we have not run into any issues that were a direct result of VMWare ESXi being at fault
• Very low hardware resources utilized to run this product

• VMware runs VSAN certification programs to make sure the OEM sells validated nodes. It helps customers to select appropriate certified ready nodes like Lenovo ThinkAgile VX which comes factory configured and easy to set up.
• Hyperconverged solutions reduce real estate space and networking costs when compare with shared storage. The host overhead also less.
• Supports All-Flash (SATA and NVMe SSDs) and Hybrid vSAN with HDD and SSD. So customers can choose cost-effective solutions appropriate to their workloads.
• Supports different storage policies, RAID and duplication, and compression features and it makes a complete storage solution.

• 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.

• It would be nice to have fabric-based storage acceptance to disaggregate storage and expand beyond the node concept. The assumption that increased storage needs require increased compute or ram is simply not true.
• The licensing costs are high but you do get what you pay for.

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.

Deploying and configuring VSAN is a relatively simple process for people that are already used to working in virtual environments, primarily for those that are familiar with vSphere. The compatibility of those two products is amazing. You shouldn't really encounter any issues and if you do, you surely did something wrong.

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.

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

Support is (as always forVMware) top notch and easy to work with. The majority of computer companies are outsourcing their tech staff, and it seems they do as well. But their guys know the product well and are quick to respond to your ticket (if the severity is right!).

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.

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.

VMWare stand out compared to all the products. However, it is worthwhile mentioning the following products can be used to achive similar results. Hitachi Virtual Storage Systems Nutanix Cloud Infrastrucure. In case if we are using Nuatinux at the Hypervisor level then it would be recommended to use their very own product for storage virtulization even though the vendors say that all their products are cross platform supportable. However, during tests we have found high performance when using same products accross virtualization.

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.

• The ROI for VMware vSAN seems very positive. We have yet to need to upgrade since we put it in a few years ago, but without the heavy cost of dedicated storage, we have already seen reduced hardware maintenance costs and reduced management time spent.
• With the cost of dedicated storage and its separate maintenance costs, all this is rolled back into the hosts. The hosts cost more with drives in them, but not near as much as the separate dedicated storage did.
• Before VMware vSAN, you had hosts and storage devices aging out, running out of capacity, or underperforming. With vSAN you only have to worry about the hosts.
