Hi Swen,
Since you need a pool to present to linstor on each node do you use any
RAID (SW or HW) for the NVMe's (or you use ZFS / VG's)?

Hi David,
1. Are you running linstor just as HCI or you also have a dis-aggregated
cluster somewhere (and some recomendations regarding it)?
we run only HCI clusters, so I cannot tell you a lot about standalone clusters.
2. Whats the resource usage of linstor (even better if you have data for a
dis-aggregated cluster)? Info I got from linstor guys is not much (probably
true just for the replication) but looking at the blog from Andrei it seem to
be CPU intensive once you start utilizing it (RAM not so much).
much less than what ceph is using on CPU and RAM. But of course you will see
some impact on server resources like CPU and RAM. Reason is drbd and network
stack.
3. What kind of hardware are you running linstor on (CPU, Memory, disks)?
we are using different cpus. Even some older like Intel E5-2680v4 and NVMe only.

Swen

Hello Swen, Bryan,
We are just evaluating linstor at the moment as well (looks very promising). I
would like to run a standalone cluster (not HCI) just for linbit (so we would
use only diskless + nfs for secondary storage).
I would have a couple of questions for both:
1. Are you running linstor just as HCI or you also have a dis-aggregated
cluster somewhere (and some recomendations regarding it)?
2. Whats the resource usage of linstor (even better if you have data for a
dis-aggregated cluster)? Info I got from linstor guys is not much (probably
true just for the replication) but looking at the blog from Andrei it seem to
be CPU intensive once you start utilizing it (RAM not so much).
3. What kind of hardware are you running linstor on (CPU, Memory, disks)?
Thanks for your answers.

Hi Alexandru,
We are also using Linstor on KVM hosts in Cloudstack and are very happy with it.

Hi Bryan,
Interesting, thank you for the suggestion. Is this similar to ceph,
installation wise? I mean a controller and storage nodes added to it?

Hey Alexandru,
We are using Cloudstack + Linstor right now and are live with a few clients.
Its open source, performance is pretty great, and they support things like VM
Snapshots, Volume Snapshots, Storage Replication, Encryption in Rest/Transit,
VM HA and more.
I think it suits what you’re looking for.
Regards,
Bryan

Hi everyone,
We have a specific scenario in witch we want to have a functional Cloudstack
cluster but we can't seem to find/decide on a working storage solution, so if
anyone can recommend a setup that meets all our requirements, please do. So, we
are using KVM for hypervisors and we want to be able to offer vm snapshots
functionality to the clients and also vm HA - that excludes Ceph. If we go for
NFS, we don't have redundancy, since we're using nvme disks only and I believe
we all know what ar the choices of raid controllers for this right now.
We're considering Storpool too, but we've yet to receive a price list, and we
assume it's not cheap but who knows.
Thank you!
