Nutanix in San Jose, California offers their software-defined Enterprise Cloud as a hyper-converged infrastructure solution. The Nutanix Cloud Infrastructure solution combines the Nutanix Acropolis virtualization solution, Nutanix AHV hypervisor (though Acropolis works with other hypervisors), Prism cluster manager, Nutanix Calm and Nutanix Flow server management, and is available on the Nutanix NX series of server hardware appliances, as well as third-party OEM appliances.

TrueNAS is a network-attached storage featuring all-flash and hybrid storage editions, from iXsystems headquartered in San Jose.
For an organization that requires top-notch performance HCI, Nutanix is the best. You may start with 3 nodes and expand the cluster as required. The management through Nutanix Prism Central and Element was so easy that even a Junior Engineer was able to handle it. The Nutanix platform is not suitable for organizations with a small budget and fewer requirements for high-performance infrastructure, as the Nutanix solution itself is suited for enterprises.
We have many TrueNAS units deployed and they've served us well everywhere. Our most common use case is using it as storage backing for virtual machines. We have Proxmox talking to it, as well as having it acting as the hypervisor. We've never lost data with it, even when faced with multiple disk failures. We've also always found the performance to be robust and able to handle the needs of our clients. Our clients range from libraries, to medium sized enterprises and we've always been able to make it work, and work reliably.
One-click upgrades; whether it's hypervisor, firmware, disk or other updates. This feature has drastically decreased complexity and administration time.
Data Locality. Not all hyperconverged technology is created equal. When I first purchased Nutanix they were the only vendor (and as far as I know, still are) that made sure the storage a VM used was on the same host that VM was running on. Given a normal operating state, the [storage] network is literally only used for replication data.
They got rid of traditional RAID. Nutanix uses software to determine where a VM's storage should be written and replicated to. This dramatically decreases I/O when changing the number of nodes in a cluster, be it on purpose or during a failure scenario. Ex. adding a new node: If one uses RAID arrays then enough space has to be set aside to create a new array that includes the new node, then all the information has to be copied over, and the old array destroyed. RAID arrays do not grow and shrink gracefully so Nutanix has designed a better solution.
The Nutanix management interface was built on HTML5. No more flash headaches!
The one downside I have working with Nutanix is the sales team. They seem to try to add in extra goodies to sales quotes or push for extras that you don't really need and you have to tell them to take them out. Don't be afraid to push back on them.
Need to analyze sizing with sales team to ensure right sizing.
AOS definitely make our dev/test virtual environment management much easier than before. And the consolidation the test/dev environment from Azure and Cisco UCS, we have less need to transfer large amount of data between different hardware platforms which was very big challenge. To expand the capacity is very easy to archive as well.
The software has been amazing. It has saved me a lot of headache in the past few years. Also, it's nice to knowing that if any of our current Synology devices were to die I can have an iSCSI system up and running very shortly. I didn't give a 10 score because I find their support to be rather slow and pedantic. They test many things when the answer is right in front of them. The compute sytem (not storage) we purchased from them came with pcie gen4 nvme's. They didn't work, but rather than believe me about the spec's in the motherboard manual saying the onboard was pcie3 ONLY they shipped me 2 replacements until I showed them an old pcie3 device worked just fine. The part that rather frustrated me was the machine was claimed to have been tested / burnt in. How can this be true if the server won't even boot up into the BIOS?
It's not out of the box easy, but once you get the fundamentals the steep learning curve flattens out and the processes to get things done and how it works becomes very apparent. It's wrapping the slight change in workflow from prior VM management methods took time to unbox and apply the Nutanix Cloud Infrastructure way
The software is fairly straight forward and if you mess up the network interfaces you can login locally at the console and fix any issues that you may have had with VLANS etc denying you network access. There was a little bit of annoying issues when setting up multiple network interface cards. Rather than keeping one interface setup with DHCP, when you add a second one with a new network it disables the first. Which makes it impossible to login again. However if you wait it will revert. I learned after works that you need to set up the network cards and then go back and setup the first one again and THEN test / apply. After that it was pretty good. The summary of the devices is very nice to. You get an accurate snapshot of how well your system is doing as soon as you login
The performance is nothing short of amazing. This is an HCI solution, and as any all-flash HCI solution is amazingly fast, Nutanix AOS fills local IO requests until its local IO is saturated before reaching out over the network. This lowers latency substantially compared to vSAN.
Our implementation team were great and worked with us and got the program up and running very easily. Every time we called post implementation we immediately talked to an Engineer, which is so unusual in dealing with companies. Everything they have promised they have full filled. I think their support is top notch.
The support was responsive for opening cases. However I found solutions to simple problems took far too long. When we had a bad power supply and we had another with the exact same firmware version they should have sent replacement for both. We had to file another case for the other PSU that started dyeing the same week. They also had to do a lot of troubleshooting to replace the fans that were not behaving as they should. I'm not a home user. I know when certain things are failing and the silly hoops the jump through made it frustrating. However, once we finally got the problem identified we had parts shipped out via advance replacement which was nice.
IPv6 is needed for link local discovery. We do not have IPv6 configured on our network so the easiest way to get our nodes configured and discovered by foundation was to configure the IPv4 addressing within the node prior to trying to discover with foundation.
The implementation went well after we got the boot drive working properly. The device was setup exactly as i asked with the hardware except for the boot drive. The reason I chose 9 instead of 10 was the boot drive put us back about a week for the part to arrive. I ended up using a personal drive to show them that they were wrong sending use the gen4 drives.
Nutanix integrates very well with Rubrik for backup and protection of the environment. Nutanix gave us simplicity and scalability compared to VMware and allowed us to extend our infrastructure into the cloud using EC2. One unified management pane for all our workloads, unlike VMWare.
I chose TrueNAS (upgrading from FreeNAS) because of the small footprint, ease of use, and reliability of the ZFS file system. The file sharing protocols supported as well as the intuitive interface all make TrueNAS a great choice for business and hobbyists alike.
We find that return on investment is probably a better metric in most cases.
ROI analysis is more than an exercise. Companies must outline what their future looks like, even if it’s vastly different from what they’re used to and comfortable with.
As good as your financial analysis might be, displacing status quo infrastructure has a lot of emotions tied to it.
Using a TruNAS integrated solution has reduced support overhead compared to using custom hardware.
Being cheaper than full flash storage arrays, this unit allows for a good balance of speed with its use of SSD-based caching drives.
The reliability of the hardware/software integration means I spend less time troubleshooting and more time doing business. Coming from a custom-built solution it is apparent that IX Systems has done some extensive testing.
