What is most valuable?
VMware vSphere has proven to be robust in nature, and the new features are quite acceptable. The new features in NSX network switching make it more useful in the reliability management of data centers.
vMotion has helped my organization's business continuity strategies during our planned DR drill activity. The migration of VMs from DC to DR is quite smooth with respect to the network link.
I assess the impact of VMware vSphere's High Availability feature on my infrastructure resilience as effective during DR drill activities and firmware upgrades, which we perform every six months. During those times, we rely on maintenance mode of several servers, and HA works properly. I have nothing to complain about.
We have utilized VMware vSphere's Distributed Resource Scheduler effectively. Even though we have over-provisioned the vCPUs, it efficiently manages the CPU cores and memory of the servers intelligently, so I am not experiencing any bottleneck in resource utilization.
Distributed Resource Scheduler has affected my resource allocation performance positively, providing a 20 percent advantage over my old hardware.
What needs improvement?
I think VMware vSphere could be improved by simplifying the packages and add-ons, which are continuously accumulating. Each feature is offered as a separate add-on, making business support and operation complex. For example, if I want to add micro-segmentation for a particular set of VMs, I need to purchase it as an add-on, but after purchasing, I cannot utilize it due to license limitations. I need to purchase more licenses if I need to provision more VMs, which delays business operations.
For how long have I used the solution?
I have been using VMware vSphere for the past four years.
What do I think about the stability of the solution?
Regarding its stability and reliability, I would give VMware vSphere a stability rating of 8.5 and a reliability rating of 8.5 out of 10.
Most features will not fail, such as vMotion, snapshot recovery, and disaster recovery points. Everything works on time. The generic and advanced features do not have issues, and we find very minimal issues in the advanced features, which is bearable.
What do I think about the scalability of the solution?
I evaluate how scalable VMware vSphere is and find that it supports both horizontal and vertical scaling. There are no questions about its scalability, as it is quite supportive.
In terms of scalability, I would rate it an 8 out of 10.
How are customer service and support?
I often communicate with the technical support of VMware vSphere.
I find the technical support satisfactory. They follow the escalation matrix and adhere to timelines. Some critical cases may get delayed, but overall my experience is a solid 8.5 out of 10.
Which solution did I use previously and why did I switch?
Before VMware vSphere, I used KVM, which is open source.
I decided to switch from KVM to VMware vSphere because KVM is a very traditional virtualization platform, and being open source, it requires manual management of everything, even though it integrates with automation tools. It does not have the robust security and nature to support enterprise-level applications. Managing it would require a vast team for operation and maintenance.
How was the initial setup?
To describe my experience with the initial setup of VMware vSphere, typically we go with ESXi with the server hardware, and each node will have a different ESXi installation. We set up a management IP and an ESXi host IP. After installing the ESXi host, we set up a separate vCenter host, which we add all the ESXi nodes to and apply the license. Then it is up and running, and afterward, we can configure HA, Fault Tolerance, or whatever we want.
I have found the initial setup process straightforward. I did not face any challenges along the way.
What about the implementation team?
I have played both roles. I am an implementer and a customer as well.
What's my experience with pricing, setup cost, and licensing?
When it comes to pricing and licensing of VMware vSphere, I think it is the costliest option in the market. When comparing to any product, VMware is the costliest, and because of that, the business top-level people are looking for alternatives.
Which other solutions did I evaluate?
Before choosing VMware vSphere, I did not evaluate other options, as VMware was the only option in the market at that time.
What other advice do I have?
I am currently working with VMware vSphere, Hyper-V, and Nutanix as well.
Both VMware vSphere and Nutanix Cloud Infrastructure have their own advantages and disadvantages. We have implemented both Nutanix and vCenter with VMware vSphere 8.0. In Nutanix, sometimes there is an appliance where it is not getting supported for some features such as snapshot functionality.
Currently, we are not using vSAN configuration as we are using a separate SAN.
We have a 96 core server cluster provisioned in a manner of 1:4 provisioning, meaning four times the physical core of the server cluster. We have provisioned 192 VMs, and everything is running smoothly. We have not experienced any VM downtime for the past eight months.
My overall review rating for VMware vSphere is 8.5 out of 10.
