2 node cluster - low cost robo


Badge +6
Bring the cost down by allowing the 2 nodes to direct connect w/10g. This would eliminate the added cost of a 10g network infrastructure for small/robo sites.

Hey Brian - Do me a favor, submit a support ticket on portal.nutanix.com with priority RFE, and ask them to associate this 2 node request to FEAT-1818.

That helps engineering and product management accurately track volume for feature requests.

That said, we're an open book, and I'll be honest, you'll be the first customer to actually formally request it. It's come up in conversations before, and has boiled down (in those conversations) to a different ask actually, which is as follows:

1 - License exposure - wanting ESXi in a ROBO, but not licensing 3 nodes
2 - cost of hardware, not cost of switching, as most ROBO environments do not need 10G performance

We've covered #1 by allowing two node ESXi + 1 node AHV clusters, that just launched in the last ~month or so

We're covering #2 with the SX line as well as a ton of ROBO sales bundles that get the cost down where it needs to be.

Thanks,
Jon

Hi Jon,

I agree that only licencing 2 nodes w/ESX is a motivator, but also not licencing Nutanix is as well. 🙂 Reducing the hardware and licensing cost from 3 to 2 on all fronts is key. Also, while 10g is not required it does give a nice warm and fuzzy that the nodes will always be in sync, also it would be a much cleaner deployment if you only had 2 x 10g crossover cables plus 2 x 1g uplinks instead of 6 or 8x 1g uplinks.

Thanks for the reply and I'll submit a feature request. 🙂

ok, great, totally understood. I'm following that feature ticket internally, so I'll keep an eye on it.

Jon, I have 2 1050 nodes that im removing from Cluster. I would like to create a 2 node cluster from these using the 1 Gb connections. Has this request been resolved. So far the answers i am getting from Nutanix support is that I must have a minumun of 3 nodes.

dbauer1 - This feature request has not been resolved yet. Current minimum is 3 nodes.

I would be interested in such an offering. If there was a 2-mode, 10gb offering we would have procured at least 2 of them last fall. A 2-node 1gb would be plenty of bandwidth for branch locations which I would love to have to displace at least 1 existing VMware installations.

hey bennro01 - following up on some old threads. Not sure if you talked to dane and ben about this, but if not, feel free to drop me a line and we can chat about 2 node stuff

I haven't but will.

I am still looking for a solution to using 2 nodes as a cluster. These are on our old 2 node 1050's. I am taking them off line next week and would like to reuse the as a stand alone cluster.

dbauer1 - Minimum is still 3 nodes as of today, and the exact requirements for a future 2 node solution have not been released yet. Just wanted to say this as I want to make sure we dont improperly set expectations that a two node 1050 cluster will ever work, as it simply just isn't a feature yet.

Has there been any update to this request on the CE platform?

The mentioned 1,2,3..... node clusters at .NEXT. I'm not 100% sure when it happens but it was mentioned.

I heard the same, didn't know if that included CE or not.

Jon. Jon, you probably know better than all of us.

...and it would be great if Jon would finally come up with an answer: 1- and 2-node clusters were already promised on the .NEXT in Vienna.

Any Update on 1- 2- node clusters?

Hi Jon,

I would actually support Brian idea with 2 node cluster for low cost robo.
I recently attend Dell-EMC MasterClass and Nutanix 1-day bootcamp, and discuss this idea with presenter. Both said it's not something Nutanix consider at this moment... citing the 3-node cluster cost still going to be better than traditional single node. IF the robo only run 1 or 2 VM, the extra capacity just a waste of resource. Maybe the 3rd node (witness) can be linked back to (utilise) HQ cluster... although the latency might be an issue.

Cheers,
Tonij

Hi,
My company would be interested by a low cost Robo solution.
Small remote sites have one or two rooms. They just need of a few VM but a replication to be able to restart quickly.
The only alternative I found is to setup 2 ESXi with local disks and use vSphere replication between the two nodes.

What is the budget? the SX1000 series for robo can be affordable, even with 3 node cluster.

In fact, we need of around 5TB of disk space for VM and NAS service.on many sites. Some of them need only of 1 TB. The NAS service could be AFS, if it support NFS/SMB on the same data, I just made a feature request. The workaround for this service is a Centos VM with samba, but one have to manage this OS.

As we have only 2 rooms/site, I don't know what to do with the third node of a nutanix cluster.
If the room with 2 nodes is lost, all the VM are lost. So the third node is useless in our case.

We want the data replicated on the 2 rooms.
So today, the only solution would be to have 2 nutanix clusters of 3 nodes.
- One cluster in room 1
- One cluster in room 2
Sync or async replication between them.

BTW, what is the public price of a SX1000 ?

I've seen them as low as 31K... Hard to justify buying two, why do you need the two boxes? one box could handle the workload- decrease your footprint.... I am assuming the two rooms are within the same building. Where are you located?
Badge +3
We need of 2 hypervisor for redundancy. If one room is down, one must be able to restart VM on the remaining room of the site.
The room can be in the same building if it's a store. Or a few kilometers away, at the other side of a plant.
Most of the sites are in Europe. But some of them are in Africa, Russia, India, Korea, Japan, US,
Thanks

Heyo! Sorry for me being so absent from the public forums in the last several months. I've been working on a handful of very large projects, which have taken up almost every minute of the day. That, plus having a 19 month old, keeps me on my toes.

RE One node clusters
We've had the ability to run one node clusters for backup only for a bit, but no VMs. We're going to add the ability to run VM's in 5.5, which is currently in the last stages of QA. Assuming that QA goes well and nothing gets clipped at the end, that feature will be out shortly. I will say, depending on use case, this make sense, and it may make no sense (think all of the standard draw backs of not having HA between servers, etc).

As for CE, we should be able to use this in CE as well once the feature is complete

RE Two node clusters
We announced 2 node, as well as one node, at .NEXT in DC (and have talked about the idea of doing it for quite some time). We took the time to do it right, and we're still working on the two node side. That said, since we're a public company and I can't make forward looking statements on the internet, I wont say specifically what release this is targeted for; however, I'll point you to our ROBO page (https://www.nutanix.com/solutions/remote-and-branch-office/), which we just recently updated with the following language:

Turnkey Virtual Infrastructure

Leverage an affordable hyperconverged solution that keeps remote applications, VMs and data protected while reducing space and power by up to 80%. Nutanix provides cluster configurations for all common ROBO environments: Micro (1 Node), Small / Medium (2 Node) and Large (3 Node). These configurations provide a consistent experience and are centrally managed via Nutanix Prism.

I'll let your imagination run wild as to what that means. 🙂
