The doc and anyone of this forum is advising to use SSDs for PBS but I didn't found a performance doc that can show the differences. I have a cluster of 3 machines (3x 2T SAS HDD) that I want to backup. Would it be enough fast to use a DL380 witjh 6x4T disks in 1+0 zfs raid? What kind of...

I understand that with 3 nodes I will need at least 2 to have the cluster to be OK. Is this correct? Would it be ok for a smal production server to run on 3 nodes with recent versions of ceph? What should I take care? Also my disks are not SSD but HPE HDD midline 2TB 12G SAS 7.2K rpm. What...

hrm so i was thinking to a RAID 1+0 but so far having SSD would be kind of expensive ... Or i should find something not HP :)

are performance impacted a lot if we setup proxmox backup in a vm? I'm thinking to extend the use of the backup server and be able to launch different vms on it. The vm of the backup server would be mounted on a zvol . Thoughts?

i have the same question myself with a dl380 gen 9 12 LFF. just using it for backup looks like a waste of resources. right now i have installed pbs and do some others internal ops to use it as a NAS when i need cold storage for vms. As a xold storage endooint i was also thinking to add some...

I see I will check. The things I'm not sure reading the doc is if this node can be configured using the UI or do I need to modify the configuration file? Also should netbox be installed standalone?

i see . is there any howto for bgp-evpn? I am trying to understand how to build it with an exit node since my router isn't working ble to handle evpn.

i'm reading this paper: https://vincent.bernat.ch/en/blog/2018-l3-routing-hypervisor and I find it interresting to be able to use the hypervisor as a router instead of relying on another router. It makes the automation easier at some point. In some way this looks like the routed model but how...

Any hint would be welcome. I would like to assign a /48 to each promox nodes that will be used then to assign a /64 or more to the VMsor containers on these nodes. Each nodes would advertise its /48 over BGP so I can eventually also have a /48 unicast range assigned to each nodes for load...

PBS looks to have the same installer options so I guess it's feasible. Is there any interrest though to have the system on a different storage or mixed it with the special device write/read patterns?

I am actually trying to setup a backup server on a DL-380. Im'm wodndering what would be thedisk right layout when having 6x4TB (SATA DD) and 2x460GB SSD Sata Mixed-Use. I'm thinking to setup the 6x4TB as a RAID 1+0 . Should I install the system on them and use the SSD to build a special...

does it makes sense though to have the system disk shared with the special disk on the same SSDs? What is the possible issue?

that's thhe plan :)

@s thanks for the answers. The plan is to take a license for all mbackup machines on the long term. If it possible to mix i may takes the risk for some time but will see :)

What are the limitation of the backup server when we don't pay the community license for now? Can we mix a paid license node with another? I would like to eventually ahve a backup failover in case of crash of the main backup server.

So I hear many sirens around, and some are saying that using ceph with 3 nodes may not worth it. Either it is too slow or over complicated. Or don’t achieve the goals of having at least 2 nodes working. Is this really the case? Any feedback is welcome :)

OK, I see. Unfortunately switches are not stackable. Maybe I should use bond? Or can we have a configuration using IPs (L3) ? I am thinking to do the following configuration: 2x1G : corosync + management VLAN 2x10G : active-backup bond, used for vm discussion. Or would a bridge with STP...

right. the subscription :) thanks for the tip!

i am using the community « license ». if i reinstall the whole thing I will need to re-register the license whih goes to the license server. And imply to reset ig on your webdite also.

I have 3 nodes with 2x1GB and 2x10GB ports , 64B GB or RAM , 2x 2To SAS (12G) disks with used for the ceph storage. I have for now set proxmox using the Full Mesh Network configuration. But I would like to add redudancy to my network. Since I have 2 10G switch I am wondering if it would...
