Oracle Solaris vs. VMware ESXi

Oracle Solaris is great due to the fact that it actually is meant for high-end servers. Supports a wide range of hardware. The Stability of the solution is great. The documentation does not support some solutions, and there are no other options. Most of the product is still command-line, despite the fact that they've got a graphical user interface in some areas. For some reason, core administration is still done via command-line.

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!

• Preferred Operating System to run Oracle Databases
• Performs well with Java and Oracle applications
• Great for Virtualizations.

Incentivized

• 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

• This could make things easier for novice users, since those who have never used the tool will have some difficulty learning at the beginning.

• 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 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.

You need to take the time to learn it. It is a massive product.

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.

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.

The support teams are well trained and responsive. Patches are rolled out regularly and are easy to deploy and backout.

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

Stress testing and timing is key. You need test systems that mirror the live environments. User testing must be reflected in peak loads.

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.

We used Windows Server quite a bit because of the ease of use for the team, file sharing, Active Directory, and systems integrated with Windows; learning was easier, and the interface was more user-friendly. On the other hand, Oracle stood out for its stability because we provide services that keep environments up and running 24/7.

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.

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

• It just runs like a top, this mean TCO is low
• We've not had issues with Solaris running on Sparc.
• Reliability is above reproach.

• 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.
