Hyper-V replication, Starwind, or something else?

Out of roughly 30 VMs, 2 are Windows server instances. We're mostly running Centos here.
I'll look into SA licensing. I'm not very familiar with it.Given that skill set, why look at Hyper-V instead of KVM? Both have been officially dropped from Starwind support temporarily until their new product roles out, which is KVM first, that's their key focus as they see it as the one with the greater future and potential. Hyper-V in general is more complex to manage than KVM. It's a fine product, but given your skill set and existing products, KVM seems like a more natural fit. Generally, Hyper-V makes sense only when you require a specific feature of it.

Oh and I've already got Veeam backup and replication (a 30 vm license) which gives me good agentless backup options for Hyper-V. 5-nine manager or something like it would likely be required as well.
5-Nine would be "extra" stuff only needed because Hyper-V doesn't have the native options that it provides. Another reason for KVM.
Veeam is great, but they have agent based for your scenario. We have another thread right now talking about this, but why do you see agentless as even something you want, let alone a driving factor in decision making? It sounds nice, but is very rarely (especially in such a large, diverse shop) viable.

@doyler3000 said in Hyper-V replication, Starwind, or something else?:
I'd need less technical people to be able to do some management when I'm not around.
This alone would be a vote for simpler KVM over complex and difficult Hyper-V. If you get everything set up and nothing goes wrong, the two will be roughly equal. But if something goes wrong, KVM is vastly simpler to maintain.

The Starwind tech was suggesting that the free Hyper-V Server wouldn't be suitable for the HCA for licensing reasons ....
Something is wrong as there is one and only one Hyper-V Server, and it is free. Hyper-V has no non-free option. There is no license for Hyper-V.

@doyler3000 said in Hyper-V replication, Starwind, or something else?:
VMWare would be a little more expensive but I do have more experience with it. This is quite a bit more expensive than option 1 but provides HA obviously which would be nice but not essential.
Hyper-V, KVM, and Xen all do HA for free. VMware is unique in that HA is not free.

@doyler3000 said in Hyper-V replication, Starwind, or something else?:
Is there something else I should be looking at that provides option 1 or 2 at lesser cost/complexity?
Without more details as to what is driving decisions, I'd use KVM, Starwind, and Veeam agent based. Takes all of your big complexities, and several of your costs, and removes them.
- Simpler than Hyper-V, and marginally better performance.
- Starwind's key platform focus.
- Solves the issues of unsupported applications and workloads for agentless backup.
- Makes your workloads platform agnostic, a key problem with agentless backup approaches.
- Simplifies everything, provides for free tools instead of costly ones to make Hyper-V usable.

If it's a good solution and solves problems he's facing with his proposed solution, it would be wrong not to bring it up. He specifically listed problems with his current approach and asked what he might do to improve it.

I was on a call with Starwind this morning including a sales person and a techie. KVM wasn't mentioned as an option. Perhaps that's because we were discussing the Hyper Converged Appliance and KVM isn't currently an option there. I'm honestly not sure though, I'd have expected them to mention it if it was going to be their focus in the future.
I was looking at the appliance because the price I was quoted for just the VSAN product i.e. the software without any of the hardware, was almost as much as the appliance (and for less usable storage space).
I know Starwind do the free version but since it lacks the management application I was sceptical about using this due to the fact I'd need less technical people to support it in my absence.
Agent versus agentless backups isn't a driving factor for me. I mentioned it because it's something I currently have. I'm not ideologically wedded to it.

That would do it, yes.

I got is straight from the horse's mouth at the time that I posted it. He definitely supersedes anyone you had on the phone.

Don't switch if you don't have to, but keep in mind that agent based is just as good and just as supported. So if the right options don't allow for agentless, don't sweat it.

In theory, that's how it should work. Basically the hardware is a wash and the software and support costs (it's all support costs actually) should be the same.
If Hyper-V is the right choice here, that's not a surprise. And if it is because it is part of the appliance, in a lot of ways you can ignore it. A server with a hypervisor is not exactly the same as an appliance with one. The appliance is a "black box" in theory and how it does its magic is of no concern, until it is exposed to you, if that makes sense.

@doyler3000 said in Hyper-V replication, Starwind, or something else?:
I want to setup a resilient two node virtualisation host production system.
So the goal is not for high-availability, but for host redundancy?
If that's the case, two Hyper-V hosts with the built-in replication just works, and works well.
Just keep in mind that going that direction, you could have between 30 seconds and 15 minutes of permanent data loss should you decide to spin up a replica if primary host dies. (unplanned fail-over)
However, planned-failover is a nice to have if live migration isn't suitable.
Being all Linux guests, no need to worry about licensing (so long as there's no software running on top of it with weird restrictions).

Yes that's how I've been trying to think about the appliance. Also since it comes with Active Support from Starwind, in theory my worry about less technical people having to support this when I'm away becomes less relevant. In fact, theoretically I would barely need to support it

Yup, that's a great way to go for exactly that purpose.

Oh so he doesn't already have the hardware?

Yes HA would be nice but I suspect we don't really need it. However when it's available (see what I did there?) for a price that doesn't break the budget then it becomes tempting.

He does not.

May be better to to go with SW's Appliance then, if the cost comparison makes sense.
