VMware ESXi still the best
- Consolidation
- Redundancy
- Stability
- Improve simplicity.
- Improve documentation.
- Improve updates.
- 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.
- We are not on the latest version yet (pre-7.0), so this might be related to our current version. Sometimes when VMs are rebooted, the virtual NIC will be in a bad state and will have no network connectivity. Disconnecting and reconnecting the vNIC will fix this quickly. It's easy to fix, but definitely an annoyance. We'll be upgrading in the near future, so we are optimistic this will be fixed.
- Due to the complexity of the environment, it can be difficult to figure out when some odd issues are related to storage or something else. For instance, there was a time when refreshing the storage connections for all hosts fixed an issue, but there was no direct indication that anything was going on with the storage connections. I don't know if this is clearer to see in newer versions, but having a way to indicate that in some way can make certain troubleshooting easier to do.
- Access to some resources requires a VMware account, while others do not. I can understand this is the case due to licenses being required for certain product support. We have never been in a situation where we couldn't access anything, plus we have all of the accounts and licenses we need. However, it can be confusing for someone new to managing a VMware environment why they can't access something they need to manage the environment.
- High-speed performance.
- Memory occupation is less than 150 MB.
- Itself allows for the basic creation and management of virtual machine.
- Remove API limitations in the free version.
- Allows more than 8 vCPUs per VM.
- Support from VMware and documentation.
VMware ESXI share hardware, save money
- Save money.
- Centralized computing.
- Allows easy evaluation of new software.
- Hardware monitoring.
Less appropriate: 24/7 environment (unless you spend lots of money on high availability servers.
VMWare ESXi - King of the Hypervisors
- Scalability
- Fault tolerance resilience.
- Centralized management.
- Host network hardware configuration.
- Physical-to-Virtual conversion can be tricky.
- Some of the back-end configurations are exceptionally tricky to learn.
On the professional end, racks of individual servers reduced to a few physical hosts save space, power consumption, and financial resources. The hosts may need to be a bit more powerful than the individual servers, so one host will cost more, but a single host will cost less than replacing 5 single servers. Even if you plan a cluster, which will cost physical raw hard drive storage space like a RAID will, the cost over replacing 5 individual physical servers still comes out cheaper. If you can justify the lower cost for the physical hardware and plan to use the money unspent there to help pay for the upper level license costs, you are good to go.
One of the best VMware Products, ESXi!
- VMware ESXi provides a wizard for the hypervisor to be installed making it very easy to configure on almost any bare metal box.
- It provides an easy interface to see information about the Virtual Machines you have set on the VMware ESXi hypervisor.
- VMware ESXi is also very easily upgradable. The hypervisor takes care of all the necessary tasks prior to a hypervisor upgrade, allowing for peace of mind when upgrading and no effect on the virtual machines you have running.
- 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.
VMware ESXi to the rescue!
- HA Failover
- SAN Management
- Cluster Resource Management
- iSCSI Storage connectivity
- Update Management
- Host Management
Backups are also made easy and straightforward using systems such as Veeam which plugs in directly to vCenter.
Highly recommended, you know what you're getting with VMware
- Quick deployment of VMs.
- Small footprint.
- Easy install.
- Backup integration.
- Secure.
- Premium Price
Highly recommended
- Allows control of VM's on the host, which is helpful if vSphere is unavailable.
- As you would expect, it integrates perfectly with vSphere.
- A better interface to monitor the logs in VMware Esxi would be helpful.
We recommend VMware ESXi
- Allows a single set of hardware to service many virtual servers.
- Great management interface.
- I haven't used it in a while, but the web client is not that great.
- I don't really have any complaints, the product just works.
VMware ESXi for K12 Schools
- Hugely reduces our need for physical hardware. Our four hosts handle over 130 virtual servers without any problems.
- It is stable. I have not had an ESXi server crash in years, nor do I really ever have to reboot them for problems. They just run smoothly.
- The HTML5 web interface has taken a while to be brought to parity with the old thick client, and a few features are sometimes tricky to find.
If your budget is low, and/or you might not have the latest hardware, some of the open source virtualization products might be a better fit.
ESXi is the gold standard for business virtualization
- Easy to install.
- Very powerful.
- Very picky about what hardware it will install on.
- Many features locked behind advanced licenses and/or additional products (like vCenter).
Well worth the investment
- VMware is not buggy. In IT we have to work around so many things for products to work the way we expect, or the way we want. I have not had to work around things with ESXi. It works as advertised.
- Sever uptime. Even with hardware failures, and system bugs, VMware keeps our systems up. ESXi has been reliable. I never even think about the OS failing or having issues. That is one less thing to worry about.
- Server deployment. We can deploy a new server in minutes. Some servers come preconfigured with OVF files where we just tell VMWare to set up a new server and point to the config file and tada there is a new server. We can create templates, where the OS and updates are already installed and we just create a new server from the template in minutes. I actually prefer creating one from scratch, and it only takes a few minutes to choose the hardware and start the OS installation. The longest part is installing the OS. It takes forever at my company to approve spending any money. With VMWare, I can set up new servers without any cost so there is no delay. When I want a server, I set it up. I don't have to wait over a month to design, get approval to order, wait for delivery, then set up the hardware, etc. It is fantastic, and such a time saver.
- VMWare's Compatibility Guide on-line is excellent. It is very detailed and easy to discover if there will be any hardware issues. When adding or replacing hosts, this is a must-visit site. It has answered every question I've had without having to call support or talk to anyone to analyze if this hardware will match that one. It is a user-friendly site that gives you all the information you need. It has given me a starting point for buying new servers when my company changed its standard on server hardware. I would not have known where to start in configuring a new host, but this site told me what was compatible with what I had and it became an easy task.
- The new interface for accessing the hosts directly doesn't work well with all browsers. We have restrictions at my company. We use Edge or IE. I had a lot of trouble uploading a file to the datastore because Edge and IE wouldn't play nice. The problem is probably mostly on MS's side, but it would be nice if it could work better with all browsers.
- Very efficient on bare hardware
- Installs a very small hypervisor footprint
- The web management interface utilizing HTML 5 is still not fully mature.
- Could use the ability to clone a host configuration in case the bootable media fails.
- Quick and accessible to provision servers as needed. Templates can be configured in VMware ESXi.
- VMware ESXi host software efficiently manages hardware resources so that a single-host server can support multiple virtual servers without causing resource contention.
- Understanding Resource groups and resource reservations can be difficult and cause issues if not fully understood.
- I would like to see better performance monitoring capabilities from the web GUI. The current options can be cumbersome, and many still need to be monitored from the command line.
VMware gives you flexibility and stability
- High availability. Clustered VMware ESXi hosts make it easy to take a host out of production.
- Storage DRS helps balance virtual disks across the cluster.
- The Flash and HTML5 web interfaces are missing simple sorting features for some lists.
- Errors messages can be vague at times, which requires searching the community for answers.
ESXi: Great for small and large businesses. Medium businesses, don't rush your decision.
- ESXi is probably more diverse in the operating systems it supports than other offerings.
- ESXi has a wide range of third party integrations to focus in on your businesses needs.
- ESXi is very rigid in its manageability.
- The management interface is not as simplistic as it could be.
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.
