IBM PowerVM vs. Nutanix AHV

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).

[Nutanix AOS] is good when you need easy scaling and high reliability. The good architecture of the solution allows to solve the tasks set for the platform. This solution allows to reduce the number of personnel serving the infrastructure due to the ease of management and a good knowledge base. As a disadvantage, I would attribute the complexity of customizing some types of loads to optimal work on DFS, for example, high-load databases.

• IBM PowerVM is reliable and fully redundant with no single points of failure
• Once it is set up, there is not a lot of maintenance that needs to be done on it
• It gives you a lot flexibility by using features like LPM

• One component to support both compute and storage needs for virtualization.
• Easy expandable as business needs arise both at the node level and larger with blocks.
• Well outlined interface with good historical data.
• API tools are available to obtain logging information from Nutanix that can be used with other monitoring tools such as Splunk.

• 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...

• Management of VMs on AHV take some getting used to. It's just a list of VMs that are displayed, and you search through it. Not the normal folder structure that I'm used to in VMware.
• Also can't disable a NIC card in a VM in AHV. Very handy feature present in VMware.
• Larger workloads may have to be tweaked to get the performance you need/want.

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.

We made a huge financial investment with this platform (four clusters, all-flash storage array), so we're in it for the long haul. Luckily it's a beast. I've had to use support more than any other platform I've administered, but the help has been very good. Nutanix continues to add features and innovations which increase the ROI

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.

Nutanix Prism Element and Prism Central are easy-to-use HTML5-based web consoles. The layout makes sense; you're only a few clicks away from getting to where you need to be. The AHV hypervisor is integrated into the platform for a fast and seamless experience. Rich data on VM metrics is also available.

The performance is very impressive. I am used to VMware and the snapshots were taking 10 minutes. The first time I had to restore from a snapshot on Nutanix it took 5 seconds and I couldn't believe it. Everything done on the server is fast. Powering on VM is done in seconds compared.to what we were using before.

Our first support ticket to Nutanix was responded to within 10 minutes of submission. That was kind of impressive. They have worldwide support so that when a support request is created, support is acknowledged in a relative short amount of time.

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.

By far, in my opinion, Nutanix AOS is heads above VMware. From the creation of a VM to updating the nodes themselves, Nutanix AOS is so much easier, faster, and just an overall better product. I would choose Nutanix AOS over VMware any day.

• 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.

• It is a highly redundant solution
• Nutanix [AOS] provides a simple easy to manage HCI platform with a reduced TCO and an increased ROI
• Centralized management solution of consolidated sever and storage solution in a virtualized environment which minimizes wastage of valuable resourses
• Offers businesses the agility and flexibility to run other virtualized platforms on the Nutanix environment
