VMware ESXi Reviews

We used it to run production and development workloads. It is quite a stable product in comparison to alternatives like Hyper-V.

The best advantage is that it reduces the footprint in your data center. By utilizing virtualization and a highly optimized hypervisor, you can run more workloads and reduce the physical space needed in your data center.

We haven't encountered any limitations because we already have a vSphere license. When running VMs, people don't request excessive configurations. We haven't reached any limits regarding storage or memory, as customers don't demand such high-end services.

In ESXi, they use different technologies like memory compression, TPS, and ballooning for resource optimization. These features allow you to run more workloads on the servers.

So, these features have been effective in optimizing server resource management.

The 6.5 and 6.7 versions already have features like graphics card passthrough and virtual compatibility.

I'm happy with the product. But what I feel is that FT (Fault Tolerance) is not used much. So maybe more focus on that feature is needed.

Sometimes, it takes some time for the level-one support to troubleshoot and respond. So, that could be improved. 

I started working with VMware ESXi in 2009, so it has been around 15 years.

It's my favorite product due to its stability. I haven't seen many problems with it.

In terms of ESXi, scalability is good. Nowadays, we utilize the full capacity of physical servers, and ESXi allows for good scalability. You can create a cluster and run numerous VMs across multiple hosts.

I'm satisfied with the support. Sometimes, when you open a case, and it lands on the first level, it takes much time to get it sorted out. But whenever level two or level three guys are involved, it’s good.

With VMware, I have worked for around 15 years, and sometimes the initial support takes longer to resolve issues. It seems like they have level-one support that takes more time. However, once the case gets escalated to level two, they provide solutions. So, VMware has a very good resource in their support team, but there are occasional delays.

I worked on Hyper-V when I was part of an SOC around 2015 or 2016. I deployed it with a four-node cluster. We used antivirus software on top of it, and I feel that caused many problems, like cluster downtime. The resource optimization was also not that great. Later, I migrated that workload to VMware.

ESXi and vCenter. My current organization only uses those two products, but my previous organizations used mostly VMware products, like vSAN, vROps and vRealize. They were a cloud provider and mainly used VMware products.

The installation and deployment are very easy for both vCenter and ESXi.

The ESXi installation and upgrade process is very easy. Even backup is easy now. The recent appliances come with configuration backup, which is a good option.

It is easy to maintain, especially when compared to Hyper-V or AWS.

In my previous organization, we used all VMware products, which were all integrated without any complexity. It was integrated with the Zerto replication tool, vROps, vCloud Director, and NSX. All of these VMware products were integrated together seamlessly. 

We also integrated some monitoring tools, and that was easy as well.

Time-saving is there. Suppose your workload is running on physical data, it’s more time-consuming and costly. But in VMware, it's cost-saving. 

In the case of Hyper-V, you would require more effort because most of the time you need to manage the VM manually due to issues. So, that was time-consuming in Hyper-V. But here, it’s easy to manage in less time.  

One of my colleagues from my previous organization mentioned that Broadcom had increased the pricing on all the products after the acquisition. 

In my current company, we have vCenter and ESXi. The company was doing a POC for the lab environment with vSAN.

Overall, it is good. I would rate it a nine out of ten because there have been issues with the support.
