    PBS with HDDs

    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...

    ceph production with 3 nodes and SAS HDD disks?

    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...

    proxmox backup in a vm

    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?

    L3 routing to the hypervisor with BGP ?

    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...

    how to assign a /48 to each proxmox nodes with BGP?

    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...

    is 3 nodes enough for ceph?

    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 :)

    which 10G switches to use with CEPH?

    I’m looking for relatively non expensive 10G switch to handle a convergent cluster fully redondant using BGP and vxlan. I had a look on mikrotik switches but they don’t have a stable MLAG yest and doesn’t seem to handle well a data network. Do anyone tested FS switches? What about a cumulus...

    HA and quorum

    I would like to setup a fault tolerant system with 2 nodes only in an Active-Passive pattern with the passive node getting all the data replicated to it. According the documentation [1] we can add an external node to maintain the quorum. Can it be used in a pseudo HA system with the data on a...
