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.

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.
