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.

DataCore SANsymphony software-defined storage aims to deliver flexibility, scalability, and cost-efficiency in a HCI platform. Powered by a block-level storage virtualization technology, SANsymphony is designed to provide flexibility to control how data is stored, protected, and accessed. The vendor states users can ensure business continuity with just 2 nodes, easily scaling out to 64 nodes, and achieve productivity for performance-demanding workloads by improving I/O processing and reducing…
I would highly recommend using Nutanix HCI for any of your infrastructure needs. I would highly suggest saving money and using the free included AHV hypervisor. The performance is incredible, and the data reduction capabilities are on par with vSAN. I would only recommend using ESXi with Nutanix AOS if AHV does not yet support some one-off configurations or if you still want to use horizon while the frame is still growing.
Now that you have virtualized your server's CPU and memory resources, you should look to do the same for your storage. Separation of hardware and software has many added benefits not only for CPUs and memory but for storage as well. Without this solution, we would not have been able to afford black-box type SANs at every location. This allowed us to virtualize over 90% of the server environment saving costs and power consumption/cooling and provides all the features costly black-box SANs, including true-HA (which most SAN vendors don't have). Migration from variant SAN storage and using mixed back-end storage solutions is as easier than ever before because the storage being virtualized.
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.
Nutanix AOS performance is light years ahead of HPE. We were nervous about using Nutanix AHV but it has been a vast improvement and saves on cost. Applications has been much improved and end users have commented. It has also freed up time for our Network Administrators and made their lives easier.
Modernizing with HCI, which creates private cloud-like data centers, is, for many organizations, the first step in their digital transformation. Companies that have kept their eye on the long game and made decisions based on a fully-developed ROI analysis have found themselves uniquely positioned to make the critical operational changes the COVID-19 situation has demanded.
In the 3 years I have been running this, I have contacted support around 4 or 5 times and that was for minor questions with exception of one time when I was performing an update on the system. And in that one time, they were very timely in assisting me with correcting the problem. Top notch customer support!
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.
We've decided to go for both VxRail and Nutanix AOS to make sure we can get the best deals from both sides. I appreciate this may not be a path most companies can go down, but always good to have a bit of healthy competition between vendors to ensure you're getting the best pricing from both sides!
DataCore is far easier to manage as well as deal with when it comes to hardware (as DataCore works with any hardware). It also seems way more affordable.
More uptime - Typical SANs have redundant controllers, redundant power supply's and can make the drives redundant by leveraging RAID-0, 5, 6, and 10. The claim to be HA but they are not. That is because if I spay water all over them or catch the SAN on fire, the storage will go down. With DataCore's solution we have identical systems (maybe even at different datacenters connected with long-haul-fiber) including duplicate storage. So one side of the solution can totally be taken offline by water, fire, etc. and the other side will remain up providing true-HA storage. Because of this, we can upgrade the SANs during the day and still keep storage services running (zero-downtime).
Lower Costs - Ability to use 3rd party hardware which lowers the costs, not only for the initial investment but as storage capacity grows.
All the features one can want - High Availability, Thin Provisioning, Asynchronous and Synchronous mirroring/replication, snap-shotting, continues data protection, deduplication, storage reporting, trending with graphs, centralized console for easier management and many more.
