Nutanix AHV is presented as a modern and secure virtualization platform that powers VMs and containers for applications and cloud-native workloads on-premises and in public clouds. Its tools and automated workflows simplify the day-to-day administration of VMs and containers.
If you are ready to build it yourself, FreeNAS is the best. I tried so many alternatives, including paid versions, and nothing compares to the power of FreeNAS. If you need an enterprise-grade NAS, you would go with an HPE or Dell because of the support, not the features. If …
FreeNAS is well suited for most storage serving scenarios, whether it be for an office file server, backup destinations, data replication across the internet, or as backend storage for virtual machines. It can serve various types of clients via a plethora of standard protocols and can easily integrate with existing infrastructure using LDAP authentication and so on. It's pretty simple to use (it helps to have at least a basic understanding of the underlying technologies) and almost maintenance-free. One scenario that springs to mind that it may not be appropriate for (yet) is as S3 storage. However, S3 functionality was added in a recent release and may have improved greatly since then. I'm sure it will eventually work very well for this.
I think Nutanix AOS is a great product and, I would recommend it to anyone. The only reason I did not give it a 10 out of 10 is because I don't do that for any product. Every product has room for improvement.
Windows Server and Active Directory is very robust and stable, it has been a staple in every IT environment I have worked in during my career. Junior to Intermediate admins can learn Windows Server easily, the user interfaces make administration tasks very easy as well as the documentation available through a vast amount of resources. There are other Operating Systems available with no GUI which has a smaller attack surface, faster update installation and reboot time. Windows Server does have the ability to remove the desktop experience, however it is not something I have had experience with and I believe most administrators choose not to remove it.
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.
Microsoft needs to minimize the update frequency by making the product more secure. It can become very exhausting trying to keep updated if you don't have a dedicated support team. It can become challenging where the business is unable to allow downtime for reboots as part of the update process.
Prone to security and audit vulnerabilities.
The operating system needs more CPU and memory resources compared to other options such as Linux.
Understanding the licensing model can be abit confusing.
Comes with a standard firewall, but not the most secured one available. Would suggest using a more secured firewall as part of your antivirus software.
Due to the number of vulnerabilities and the operating system being a target for hackers, anti-virus software is a must.
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
I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.
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.
Anyone new to IT could easily use the familiar Desktop Experience (GUI) version because we all know how to use Windows, whether a client or server version. Once an IT user is more comfortable with the operating system, they can move on to the Core version, which is the way to go in almost all situations.
Due to the cool DFS architecture, Nutanix has good read performance for loads. In general, everything works well. We only ran into problems with very specific workloads that did not allow multithreading. It is also worth noting that loads should be tuned according to best practices for best performance, which is not always an easy task.
Nutanix [AOS] is a leader in the HCI industry and it becomes evident after deploying the software. The solution runs effortlessly and can scale seamlessly. We ran the Nutanix solution on Lenovo Servers and since Lenovo has a close working relationship with Nutanix, you can procure the Nutanix software directly from Lenovo as part of your Lenovo HCI solution. The advantage of going this route is that the hardware has been tested and verified by Lenovo that it is thus certified for Nutanix. The support is then also directly with Lenovo for both hardware and software.
Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.
Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.
FreeNAS effectively uses all resources really well and it is highly recommended for in premises NAS. It has unlimited ROI as it is really free and open-source. The only payment we need to pay is when we need any support from those guys. FreeNAS helps us to effectively do our work with the legacy systems as it manages all the components really well. FreeNAS although rebranded to TrueNAS will still be there until our legacy systems run.
We looked at both Simplivity and Cisco HyperFlex. Both are pretty good in their own right. Simplivity was very 'efficient' in the way they handled data, but we didn't like the idea of a propitiatory hardware card. Cisco's HyperFlex was our second choice, but we were so impressed with what Nutanix had done for us already, that we were already leaning toward that.
They are different experiences, and while the other solutions offer enterprise-grade stability and, in some cases, address Windows server shortcomings (such as patching), they all do the trick, but the other solutions require a deeper technical background/configuration of items at the command line, which some people are not fully comfortable with.
Nutanix Beam helps enable enterprises to take control of their total cloud spend with automated cost governance policies. Beam provides unified visibility into public and private cloud spending, including clusters, VMs, and other services.
Lower administrative overhead, increased employee productivity, and costs savings.
Nutanix AHV is also generally free to use, which can benefit organizations with budget constraints.
