VMware Workstation Pro is virtualization software which allows running multiple x86-based operating systems on one PC. Users can run Windows, Linux and BSD virtual machines on a Windows or Linux desktop.
The best and easy to adjust all the functions for easy production of the appropriate and quality services via the Cloud and the deployment of the product can easily be done with all users even those with little basic knowledge on VMware Workstation Pro similar platforms. With …
IBM PowerVM only is available on IBM POWER machines. It makes live much easier, compared to bare metal machines (OPAL) or machines with KVM. Personally I would not like to manage systems that don't have IBM PowerVM. The current line-up always includes IBM PowerVM (firmware built-in).
Some scenarios where VMware Workstation pro is best suited are: 1. Utilization for testing software - can install a virtual machine to simulate software requirements and testing it on your network. 2. Testing operating systems upgrades and installation on specific hardware requirements. 3. Virtualizing a physical server 4. Being able to backup a whole server and restore from it in the event of any issue occurring.
Each LPAR comes with a profile that sets a minimum, desired and maximum capacity (like for CPU). You can freely change the allocated CPU between the minimum and maximum on-the-fly. If you want to change the resource below the set minimum or above the set maximum, you need to shutdown the partition first and change the profile. It would be nice if there was a way to do that without downtime too.
(Setting the maximum very high is fine for CPU but not for memory as it allocates a fixed percentage of the maximum (not the current) size for internal housekeeping).
When you manage your Power system with an HMC, a lot of firmware updates can be done concurrent (on-the-fly), not requiring a power-cycle of the machine. If you use Novalink to manage your systems, this proces becomes broken and you need downtime on your physical system. You can use Live Partition Mobility to move every partition off of this system first, but still...
Making it easy to export VMS is something that Workstation struggles with; exporting to OVA which is the primary type of VM we export to is cumbersome and can be difficult without proper knowledge on how to do this.
Management of VMS could be a little bit more in depth.
I think the networking portion of Workstation could use some slight improvements, more in-depth segmentation to support containers, however, this is a small issue and not something many people will miss or need.
The product works. It provides the proven environment to support IBM's primary operating systems that run on the IBM Power processing systems. This by extension includes the IBM various storage products that work within that environment. It has proven to be seamless as the environment has grown and as various new products and version updates have been added. As with most IBM products, the support is excellent.
Since it is built into the firmware (hardware) it requires no separate installation (except for the Virtual I/O servers, if you need those). Both HMC and Novalink (with PowerVC) support IBM PowerVM well and offer a user-friendly interface to setting up LPARs and making changes, most on the fly. Modern systems also give insights into performance, power consumption etc. A lot of separate tools exist to show more details, like LPAR2RRD, IBM Instana, IBM Turbonomic etc.
It is well documented since it is a long actor in the virtualization scene. Easy to use for most user cases. Pretty much not maintenance on the software besides the occasional software updates and/or compatibility issues from time to time.
I haven't had to call VMware Workstation support. The majority of the time, whenever I have a problem, I can perform an online search and find the answers I need. Online forums and users with similar situations are generally sufficient to answer any questions I have had, though, from previous experience at another company, their support is outstanding and responsive to circumstances. However, that is generally for a paid support contract and should be expected when you are paying for that support.
IBM PowerVM is the best and most stable product in the virtualization market. It gives the best performance with IBM Power Server, especially its best solution, where we have to run critical applications and save applications licensing costs. It provides a lot of good features like LPM, shared processor pool...etc, which makes the environment more flexible.
VMware Workstation does have a price unlike VirtualBox, that is free. But, Workstation Pro makes up for it by how many features comes with it. We are also able to take VM's in our vSphere Production environment and spin it up on and isolated laptop for sandbox testing within Workstation Pro. I'm not sure that VirtualBox is able to do that
It has provided the performance we need during month end and year end closing cycles.
It has been very reliable with little to no downtime.
We have been able to stretch our IT dollars because the refresh rate on IBM Power can run for years. Also, we have been able to add many more VMs to physical machines than other platforms can run.
The ROI on Workstation would be hard for us to compute. It makes things easier to do and to get access to, but there are other applications and methods to do much the same thing.
Where there has to be a some form of ROI is in the fact that you will actually do things that you might not otherwise do simply because Workstation makes them easier. Sandbox testing is a good example of this idea.
