Nutanix AHV

Nutanix is a good solution if:
  1. You cannot afford to have your services go offline.
  2. You want peace of mind that comes from total hardware redundancy.
  3. You are comfortable running commands through a terminal emulator.
  4. You want a system that largely manages itself in terms of keeping your VMs online.
  5. You're concerned more about bullets 1-4 than you are cost.
Nutanix is probably not a good solution for you if:
  1. Cost is your primary concern. In this case, you would probably be better served using something like Microsoft's Hyper-V replication, which is included with the cost of a Windows Server license.
  2. 24x7 uptime is not critical, there are cheaper and easier solutions to achieve near-constant uptime (see bullet one, above).
  3. You are not comfortable working at a command line or don't want to pay for tech support.

VMware ESXi is well suited in almost every environment. Even the smallest of organizations can benefit from the ease of migration and backup/business continuity that this product allows for. Where it struggles for these small businesses is in the cost model. The redundant hardware and licensing can be cost-prohibitive to a small business. Beyond that, I wouldn't run a business without it if I could scrape up the resources.

Pros

Nutanix AHV

  • Nutanix AHV removes the headache from clustering. Once it's set up--which a Nutanix rep completed--the system is largely self-managed.
  • It was a turnkey installation, and I was building virtual machines from day one.
  • The system automatically manages moving VMs from cluster to cluster when software updates are performed on the Nutanix system that require the nodes to be rebooted, so there is no down time.
  • System management from a web browser is easy management, as it can be managed from anywhere there is Internet connectivity.
  • It supports Windows and Linux VMs equally well, allowing access to the VMs from within the browser. This can be much easier than using remote desktop or VNC.

VMware ESXi

  • Virtualization allows us to create machines that handle specific tasks rather than a bare metal OS that uses the entire hardware; on bare metal, an admin has to use the machine to handle multiple tasks which is confusing to administrate.
  • VMware is fantastic at migrating systems between hosts. This is important to distribute load and for consideration in case of hardware failure.
  • VMware makes automation a snap, we currently use puppet & kickstart for our automation software. Virtualization allows us to be agile in creating systems and destroying them. Before VMware we had to provision machines by hand which is costly in labor costs.
  • VMware has some exciting verticals that integrate well with its hypervisor, VSan comes to mind which helped us address our need for resiliency in case of a hardware fault.

Cons

Nutanix AHV

  • Nutanix has a huge learning curve. We purchased the on-line training course when we moved to the platform and it was literally weeks of instruction. It was so extensive, in fact, that we ran out of time to complete it before the test.
  • Operations that cannot be done from the browser require running commands from a terminal emulator; perhaps owing to the newness of the platform, documentation is not robust. I highly recommend you buy the tech support.
  • Software updates are sometimes rushed to release. I've gotten to where I wait at least a few weeks after release before installing them, as I've run into significant issues with buggy software. Such installations have required time-consuming tech support calls to resolve.
  • While the promise of perpetual VM uptime is being fulfilled, the dashboard frequently reports issues that need to be resolved.
  • Because of significant hardware redundancy, the cost per byte of storage capacity is high.

  • They continue to improve on moving from Flash to HTML 5 based management.
  • I'd like to see more flexibility in how multi-site VCSA redundancy can be deployed.
  • I'd like to see some of the automation and orchestration tools become more affordable for the small to mid-sized business market. vRA/vRO/vCloud..

Me, not likely as my current company doesn't use it nor do I use it at home. However, I don't see my previous company ever switching away from it.

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.

If VMware ESXi support is needed and you have the correct support contract, the support is fast and usually very straightforward. But it is, in most cases, possible to find helpful troubleshooting information or tips with a well-defined Google search.

Alternatives Considered

Nutanix AHV

There are other clustering solutions, to be sure. And there are significantly less expensive solutions for preventing downtime, such as Hyper-V replication, which is what I was using before Nutanix. But Nutanix is in the upper-right of the Gartner magic quadrant for hyperconverged solutions. If you want an all-in-one solution that comes highly rated by industry experts, it can be a great way to go. It was also selected because several peers had selected it and had good experiences. I've used Hyper-V (which you can run on Nutanix instead of AHV, by the way, although you lose many of the cool features AHV offers) and VMware (which you could also run on Nutanix), I have not found myself wholly missing either of those products by using AHV.

VMware ESXi

The only alternative I see is the Microsoft Hyper-V, however in our case we have used VMware products for years and have not thought of migration mainly because of the great stability level and ease of management they provide to us. Also it fully integrates with our hyper-converged infrastructure as no other products can do.

Return on Investment

Nutanix AHV

  • In the 20 months we have had Nutanix, our VMs have always been available. That was the goal with this purchase.
  • The peace of mind is incalculable. Automatic failover, total hardware redundancy, automatic VM provisioning--while it's not always easy to work with and causes headaches in other ways, the bottom line is we are always up and it fulfills its promise. While I cannot measure the ROI in dollars and cents, the reduction in stress is a significant ROI, and management is pleased, too.

  • When speaking about ROI, it is excellent to think about all the hardware maintenance that you save.
  • It also saves when you are getting an A.V. solution since some technologies need only to license the number of CPU cores.
  • it helps to reduce the costs of backup since you can backup many severs within the same technology.
