HA Proxmox without license

[fab.aravena]

Hi community,

I'm new using Proxmox and i found it very useful and complete. My questions:
- I can use HA and network storage without license?
- What are the features or service give me the license?

I'm interesting in configure 3 nodes with DELL Storage PV MD3420 with SAS disks. I need to know if i'll need license and if this storage (or Dell storage) is compatible with Proxmox. Any succesful story?

Are many questions ... i hope you can help me.
Thanks!

1. Yes, you sure can.

2. The subscription allows you to access the enterprise repository, which is generally more stable and well supported than the others. However, even the non-enterprise repository is very stable, most days. The subscription, depending on your level, also gets you access to support if/when you need it. And finally, you're helping support the project with your sub, which is always good.

As for the storage, I honestly couldn't tell you specially. However, I'm assuming with Multipath you should be fine as long as the controllers are supported in the kernel.

Just to clarify that, all code is licensed under 'AGPL'. So we do not sell 'licenses', only service subscriptions.

You are right!

Thanks for your reply 1nerdguy! So, my only question is the compatibility of this storage:

Storage PV MD3420, 8 puertas de SAS 12Gbps (4 por controladora), Dell 1.2TB, SAS, 6Gb, 2.5", 10K, HDD (Tier-2) 12, Mission Critical Package: 4-Hours 7X24 On-Site Service w/Emergency Dispatch, 3 Year

I saw topics in this forum with SAS storage and LVM or NFS, but with LVM is not possible do snapshot ... so i dont know what is the best or recommend escenario for this kind of implementation with SAS storage.

I hope the community can help me, thanks!

I'm using a MD3200 as shared LVM storage. The only thing you should pay attention to is that you can't snapshot for backup on one node while the VM is running on another. Consequently, if you have two VMs on different nodes configured to concurrently access the same LV, you can't snapshot it.

Thanks for your reply NdK73!
Then, based in your reply and topics in the forum LVM is the best choise.
So i have 3 nodes (DELL R620) and 1 shared SAS storage (MD3420). I need to configurate the storage like LVM ... i need to know another things? ... some type of special configuration? guide or wiki?

Thanks for help me!

Look at multipath configuration. And test it before going live.
For example try disconnecting a cable while it's being heavily used both for read and write. Check if recovery works as expected.

I don't know MD3420, but with MD3200 we've had a complete lockup (something that should never happen on such a machine) because of 5 consecutive failed controller reboots -- took about 3 days to return to normal operativity. Plan having backups offsite for such a disaster.
