New setup DC

[Testani]

Hi, i'm going to move my dc setup from 3 x ESxi nodes to 3 proxmox node using zfs and zfs sync. We need 3 node with 256 ram per node and 6/8TB usable SSd datastore for host. Can i have your advices?
I'm looking for experience using Kingston DC500M disks, is that a bad choice?

Thanks

When using 3 nodes you might also want to consider running ceph. Got some advantages over ZFS, for example, that it is a real shared storage and not just a synced local storage, so your guests won't lose a minute of data when using HA and one of the PVE nodes fails.

i need a very simple infrastructure due to lack of management skills of my team. I think that a cluster with zfs sync with 5/10min RTO could be fine for my needs. Ceph is great but i'm quite scared in 3 node setup.

If you don't care loosing 5 or 10 minutes of data then that's a valid option. Really depends on what you want to run on those nodes. I for example wouldn`t want to run a webserver with a online shop on it, where customers then order something and already paid for it but never receive any product because a node failed, so all orders of the last 10 minutes are lost, and nothing is ever shipped.

Maybe it's time to build skills or let others take care of your system. I would not run a system if I would not know exactly what's going on. Customers depend on it like @Dunuin already said.

ZFS has it's own quirks - same as ceph - and both have a steep learning curve. You will for example not be happy if you choose anything other than stripped mirrors and will run into problem with space usage down the line (a ton of posts here in the forums) because RAIDz works different than you think.

You are right. I am not afraid using ceph netgear zfs, i want a very simile setup be cause i don’t want to be the only one that can manage simile operation of management. There are no e commerce in this cluster so i am just thinking a solution to reduce esx and Windows license costs
