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.
Well suited for mainframe CKD based applications. There is unmatched synergy with IBM zSeries when compared to the competition, for example zHPF, SUPERPAV, zHyperLink, cache management and replication technologies. For distributed, the fact that Copy Services Manager comes with the box is a great move on IBMs part to provide replication capability no matter what the applicaiton. I think the DS8k is less suited for smaller distributed environments. I think product overlap with V9000 in this case
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.
Remote Copy -- The DS8k has decades of excellent code built to handle the most demanding environments for mainframe or open systems and can be combined with automation solutions like GDPS or Copy Services Manager
Reliability and Availability -- This is the platform that gets used for the most demanding environments, even when FICON attachment isn't required
Continued enhancement -- IBM continues to put resources into the DS8k and the platform has advanced with the technology from z and power
Mainframe synergy -- Poughkeepsie communicates and works very closely with the DS8k developers
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.
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 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.
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.
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.
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.
