Which is better in terms of functionality and management? 
Deb BerczynskiPlease see response below from Shane Hill, PMP Arrow SI Practice Manager, Data Center Infrastructure vSAN was not originally designed to be a replacement for Enterprise storage systems. It was originally designed as a low cost alternative to them for Small Office Branch Office. It then got dragged kicking and screaming into today because of companies like Nutanix as competition. Even with vSAN R6.6, it’s still got some glaring misses. * Restricted write buffer size * Maxiumum number of nodes * Long rebuild time * Deduplication/compression/erasure coding are only available with All-Flash * No data locality * Only available with ESXi * Datastores/Disk Groups don’t survive an SSD failure in a hybrid system * You can’t pin a VM to flash As far as management goes, Nutanix kills vSAN hands down. In my opinion for 1 big reason. The rest are just icing on the cake. The big reason is one-click upgrades. I can upgrade all the nodes in a cluster by logging into the PRISM interface, choosing upgrade button, hitting download latest button, and hitting upgrade. That’s it. It will do a rolling upgrade of the Nutanix software with zero downtime. Upgrades of the bios, firmware and even ESXi(if you are using it) are done similarly. I upgraded the Nutanix clusters at a major health insurance company during business hours last week. That was 13 nodes in the primary cluster and 12 nodes in their DR cluster during the day without downtime. Now, doing hypervisor upgrades is a little different in that you still have to move the VM’s as each upgrades. Other things that I love about nutanix. * Native backup to AWS or Azure * Self Service Portal- allow a non technical user to deploy a VM. You can even script the SSP to authenticate with Service Now and allow a VM to be created from a Service Now template ticket. That is slick! * One pane of glass. All management for the AHV hypervisor and the cluster are done from within PRISM. There is even an integration to vCenter so from within the PRISM interface I can do 90% of VM management of ESXi VMs. IE, stop, start, console, edit, etc. * Integrated tools to allow migration from ESXi to AHV while the cluster is running. * Can run File Services natively and manage it from within PRISM * Publish iSCSI block storage to VMs AND bare metal servers outside the cluster. I love this. We use this a lot.
Hector MaldonadoI been using VMware for long time and they have a very robust product that for quite some time. We used vSan to consolidate some low budget storage in order to maximize their use however, We switched to Nutanix seeking performance, flexibility to use both SSD and HDD, Licensing savings and of course one of your questions, the usability and simplicity. After a year, I do recommend Nutanix because is simple to use (management and processing tasks are far more easy, fast and clean than VMware) , performance and the ability to select which kind of disk I wanted to run my VMs. Nutanix storage show you a single container for all vms that has the capability of managing I/O loads and prioritize them across disks. In terms of expansion of resources, just adding a new host or storage node will expand the cluster easily. In the case you use DELL XPS server, you can add Disks to each node to expand storage without adding new host (If you have the physical space of course). Nutanix user interface is clean, already tested in all browsers and their support is fast with a few clicks you can almost do everything. Really fast interface response. Replication and protection is built in with consistent snapshots and also it has real-time statistics of the health, network, protection and hardware in the same management console. Basically you do everything in the same place. Migration in Nutanix was a snap, easy and without complications, they had a tool that help schedule migrations without user input that connects to VMWare and migrate and translate all VM needs into the new system. I use the VMware Client completely because the interaction everyday, I found the Web version not as fast or responsive than the old client and also managing storage between the cluster sometimes get messy, compatibility issues, orphaned snapshots, even sometimes if a host failed, the vCenter Appliance does not respond well restoring the cluster HA sometimes and needed to disconnect, reconnect the hosts in order to make it work. I do not tested simplivity but I did use this link because I liked how they evaluate each solution: >> http://www.datacenterzombie.com/hyper-converged-infrastructure-comparison/ I recommend to specifically look at the upgrades section. I already did various 1-click upgrades without production interruption in my Nutanix Clusters in comparison of VMware with HPE where I need to upgrade SAN firmware to fix performance issues and I need to take all the cluster down to perform it and I rather prefer to let HP support (that of course has costs involved) to do it in case something go wrong. Another good information source ( see Figure 1. HCIS Key Feature Comparison) here: >> https://www.storagenewsletter.com/2015/07/08/hyperconverged-infrastructure-solutions-simplifies-midmarket-data-center-gartner/ We been with HP for more than 15 years and we switched to Nutanix hardware because instead of purchasing hardware, Hypervisor software and upgrades, monitoring and alerting software, backup software, basically we got it all from Nutanix tested, built in and ready for function in no time. This of course is my opinion while using both platforms while I finish the migration of very old databases to the new Nutanix system. Hope this information helps you.
JeffreyThat depends on many factors and understanding where HCI is going today. The marketecture of HCI would have you believe that architected with hybrid-cloud cloud in mind. For the enterprise, hybrid-cloud will be the new norm. I think Nutanix has done a remarkable job moving the discussion beyond an HCI to one that includes other things to a point where the Nutanix solution is an OS. As for AHV, it's grown by %25. On the flip side, VMware has also done a remarkable job in partnering with AWS and others. MSFT now has Azure stack and linux consumption has grown %70. The last man standing without an on prem HCI solution for a hybrid cloud is Google. The Nutanix DNA comes from Google and have signed a unique partnership with them. A lot of this could come down to, which public cloud makes the most sense for your business. The goal of Nutanix, VMWare and MSFT is to create a single pane of glass of O&A like VRA. Each one can do it today. But what if you want an HCI multi-cloud solution. Then you may need to consider Cisco C3 and pick the HCI solution of your choice.

Which solution would you recommend, Storpool or Red Hat Ceph? Why would you choose one solution over the other?  Thanks!
Naran McClungFrom a mate of mine who’s closer these technologies - pasted verbatim: “Ceph is an open source solution and part of the industry acknowledged OpenStack solution championed by Red Hat. StorPool is a startup out of Bulgaria with ties to Google and a couple of other industry darlings via alumni. It would all depend on the use case and the benefits of each solution against that, but I’d probably back Ceph as being more widely adopted and therefore widely tested, and with an army of Red Hatters behind it to remedy any issues and Red Hat support I doubt it will run out of funding like so many other niche players do without a benefactor. That being said if StorPool proves itself then I imagine it will be snapped up by someone fairly quickly ala Nimble/HP. Possibly one to watch but in a crowded market it would be hard to differentiate.”
CX & Product Strategy at a tech services company
I wanted to see if anybody had any opinions on why Nutanix is gaining such ground on VMware? Is it because of their interoperability, support transparency or relationship with their partners? Eager to hear your thoughts.
We are going to purchase a new main storage device. I would like to see more opinions on the selected products which are quite similar in my opinion.  The history of both products is also quite similar except the purchase of ScaleIO by EMC which increased the pricing of ScaleIO but made this product much more "reliable" in all points of view also. The pricing of Storpool is interesting, the bundled services also, in fact the whole sales model is OK. But I am not able to find enough independent information about Storpool which could mean that the product is just good or...  Do you have some deeper experiences with Storpool? Thank you.
