Cisco FlexPod vs. Nutanix Cloud Infrastructure

FlexPod is great for mid to large size companies, where the flexibility and depth of a traditional SAN and high performance servers is required. For smaller companies, it might make more sense to go with a hyper converged solution such as Hyperflex or Nutanix (both of which can still run on Cisco UCS servers, but would not be making use of Netapp storage), to meet the requirements in a smaller footprint.

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.

• Single Pane of Glass Server Administration.
• Ease of firmware upgrades.
• Incredible support when you have an issue. The Cisco/NetApp/VMware FlexPod support teams work together and drive your issues down to the root cause.

• 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!

• KVM control of the blades still requires Java. Avocent is using HTML5 now, and it would be nice if the KVM console for these UCS blades could too.
• Price - Like any Cisco product, there are cheaper options. They aren't nearly as fully featured, but at times, it would be nice if UCS could be a bit cheaper.

Incentivized

• Can be priced high at times.
• 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

So far no issue on availability during no issue on network or power outage

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.

We requested more training than typical which was very in depth

A lot of online training courses, most of them are free.

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.

Being a Cisco shop already it was a natural fit to go with a solution based on their technology. Then add in VMware which we are were already using - that was two out of the three for the FlexPod. Then factor in NetApp's de-duplication technology and flexibility in configuration and options and it's a match made in heaven. Not to say we haven't had some stumbles and some issues but it works and it works well.

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 have scaled our products over the years and continue to do so very easily.

• FlexPod has allowed our team to be extremely quick to resopnd to new VM build requests. The amount of RAM, CPU and backplane offered by B series blades allows us to go with very high VM density. The quick deployment of service profile templates also means that when we have to add new hosts, it is done quicker.
• FlexPod and the service profile portability (along with VMware) has allowed for full upgrades and migrations from M1/M2 series hardware to M4 hardware without any downtime or outages to the clients. Blades can be moved into new chassis, or service profiles moved to new generation blades, with no impact to the customers' ability to work.

• 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.
