- Improve updates.
VMware ESXi the only real choice
- Ease of Access to all of my Virtual servers.
- Great performance visibility.
- Easy to Grow at a moment's notice.
- Complexity - if you're not familiar with the product there is a learning curve.
- VMware ESXi could find a way to boot faster.
Small environments of less than 3 or 4 servers might not need VMware ESXi. This is due to its higher ROI for them.
VMWare ESXi is still the king of Hypervisors
- Virtualization - it allows you to take full advantage of your hardware investments
- Flexibility - it allows you to run services across disparate hardware types
- Scalability - it allows you to expand and deploy new services rapidly
- Complexity - if you're not familiar with the product there is a learning curve.
- It does require other licensed VMWare products (vCenter Server, etc.) for full functionality.
ESXi is still the best virtual host platform among hypervisors
ESXi's purpose is to act as a host platform for creating, running and managing virtual machines of various types, i.e. servers, user endpoints, appliances, web servers, SQL servers, etc. It's similar to Hyper-V (the Microsoft-branded competition for ESXi) but in my opinion, it has more and better features, overall, although the learning curve for ESXi is both steeper and longer for system admins than most other hypervisors.
Why do we use it? ESXi enables us to host many virtual servers and other endpoints on one physical host machine. This saves on electricity, space, heating, and cooling and improves ease of management of the hosted devices for everything from rebooting them to backing them up to restoring them.
Short answer? For small, medium or large enterprises, ESXi is (still) the best choice for hosting virtual machines. It really doesn't have much legitimate, serious competition in the world of hypervisors.
- ESXi makes management of hosted machines easy. Everything is in one place. If you have a vCenter (which costs extra) to manage all your ESXi hosts, then everything is truly in one place and there is no need to hop around from management tool to management tool. Al the virtual machines' hardware settings, OS information, storage volume information, backup information, even a remote console just like a KVM ... all of it is in one place.
- ESXi balances workloads well when using vCenter. Behind the scenes, the vCenter allows an ESXi host to "talk to" other ESXi hosts and when one VM has resources usage that gets past a certain threshold, it can move virtual machines around to balance workloads, even while the machines are running and service users. It's completely invisible to the users, who don't experience latency or any kind of interruptions when their VM is being moved.
- The vSphere / vCenter GUI is complex. This is because there is just a crap-top of stuff that ESXi manages, so there is frankly a crap-top of necessary stuff that you have been able to manage in the user interfaces. The learning curve is a little steep. Just because it does a lot of things.
- Live (powered on) ESXi snapshots of VMs still don't act as SQL backups very well. Snapshots can't backup SQL reliably because of the architecture of SQL and how it interacts with the live resources running on the VM. This is one of the many reasons why taking a snapshot works better when the VM is powered off. This is also why we don't rely only on snapshots to backup our VMs. We also use Veeam and for critical SQL databases we use native SQL backups and in one case, another backup solution (Veritas) that can do SQL better.
If you want a free hypervisor? Then you need to try Hyper-V first to see if it can do everything you think it should be able to do. Hyper-V comes with Windows (both the server and PC flavors) as a role. It can do some basic functions of a host. But it doesn't have all the full capabilities and management features that ESXi hosts do when managed with vSphere / vCenter.
VMware ESXi is a rock solid choice for your hypervisor
- Just works. VMware ESXi is a proven solution with a lot of additional components that provide more value.
- VMware ESXi is a great platform for new users to learn. Having both GUI and CLI components to manage the host server and subsequent virtual machines allow for click-based admins to get work done, while also providing the avenues for streamlining with automation within CLI based connections.
- I would love for some of the features only available within the upper tiers of ESXi licensing to be available for Standard licensing purchases. There is a vast difference between free, standard, enterprise plus licensing.
- The learning curve might be an issue for some users, but can be overcome with the vast amount of resources available. You might have to train to find all of the resources as well.
Server virtualization done right
- High Availability
- Resource management
- Hardware virtualization
- The licenses policy are not very rigid and the best options are stuck behind the most expensive license.
- Configuration management is limited versus some other products currently on the market.
- Better/simpler automation would be great, for example automated ways of doing blue green would be very welcome.
ESXi, hypervisor extraordinaire!
- Stable software.
- Supports many guest OS'es.
- Allows for automation.
- Allows for more uptime.
- Quality support can be hard to receive.
- Licensing for features can be expensive.
- The learning curve for new users can be steep.
ESXi fan because it makes my life easier
- Makes it incredibly easy to deploy new virtual machines.
- Works well with our SAN and our backup software integrates nicely with ESXi.
- Their support has been helpful when I've needed it.
- We are on version 6.0 and it has some Flash problem with browsers. We could not manage vCenter after a Flash update in google and had to use the thick client.
- It would be nice if it was easier to update. They have gotten better with subsequent releases but it's not great with 6.0.
- It's not cheap compared to Hyper-V
VMware Review
- Allows system administrators to manage multiple hosts via one interface.
- Perform multiple management tasks
- Provides excellent memory management
- Learning curve for support staff
- live migration of hosts supporting realtime protocols
- some maintenance requires downtime
VMs and ESXI info from a good user
- IT admin has complete control over these VMs through ESXi as well as being able to release a new VM if the prior VM system has any issue, this saves hundreds of hours for our admins.
- Using ESXi together with VCenter is a great platform for maintaining the VMs, virtual networks, building datacenters, and tracking what is going on with our VMs.
- ESXi that I had set up as a lab to learn from and to teach others off of saved our entire network from a serious hack out of China. When I set up this ESXi as a learning platform I set it in a way that it was the main point of our network (by accident) this accident stopped a brute force attack that was done through a 3 day weekend with over thousands of attempts to hack into. They only got into a BS VM that was set for learning. This saved us a lot of money and embarrassment.
- Better way of teaching, make ESXI easier to learn to use
- Configuration need to be a bit easier to understand
- VMware needs to do something about the learning costs
My experience using VMware ESXi
- VMware ESXi is number one in server virtualization for a reason. They have been doing it for a very long time and do it well!
- The ability to migrate workloads between hosts or even across different vCenters with no downtime is amazing.
- Being able to virtualize the storage with vSAN and networking with VDS switches or NSX is amazing!
- As vSphere has been my primary area of focus for the last 6 of the 10 years I've been using it, I really don't see problem areas anymore. The product has grown and continues to grow!
- Learning the entire VMware product family is not an easy thing to do without training. I recommend setting up a lab at home to learn. Look into the VMware User Group's VMUG Advantage program for licenses for a home lab.
VMware ESXI beneficial for server environments
- VMware allows us to save time by installing servers much quicker than before, through the use of templates.
- VMware vCenter controls all aspects of our server environment through one console and provides detailed hardware information.
- The ability to move virtual servers from one host to another in a matter of minutes, which allows us to install server upgrades with no downtime.
- Licensing costs are high, and are done by CPU, rather than per server host. As a result, this can add up pretty quickly with a large server environment.
- Learning curve may be higher for those people that have not used a virtual platform.
- Some applications have reduced performance in a virtual environment, and run better on physical hardware.
VMware would be less appropriate if a business only has several servers, because they will spend more on licensing and will not appreciate all the aspects that VMware provides (redundancy, disaster recovery, system upgrades).
No Money? Managing less than 5 physical nodes? Use Vmware ESXi!
- GUI is very easy to use. Learning curve is low.
- This software can be deployed for many nodes through puppet.
- The ability to do snapshot restores quickly is great compared with ovirt.
- To utilize vmware esxi fully, you need to couple it with paid software (vcenter).
- Not easy to automate the deployment this software on many nodes unless you purchase vcenter or puppet.
- No ability for DRS unless you buy vcenter.
VMware ROCKS
- Hardware utilization for virtual machines
