    Nic's bond for CEPH

    So you have much more experience then I do :) Do I understand correctly that if I add to bond 2 LAN adapters doing VLAN or without VLAN, in case of my one nic or switch failure the system will work?

    Nic's bond for CEPH

    If I can use rules for private network it makes sense. Thanks I will look for the information on QuS! My network cards don't support 802.3ad. As I read alb mode loadbalance a single stream, but CEPH makes more requests with a lot of streams so it useful I think. All my servers will have a single...

    Nic's bond for CEPH

    Let's say I bond two NICs and add on that bond one VLAN for public network and other VLAN for private network. As I understand that in case of disk failure, the restore process will start and all my private network bandwidth (1GB+1GB bond) will be used. Public network will suffer. So how does...

    Nic's bond for CEPH

    So you mean that I can do the bond on Proxmox and then I could set this bond also for VM or CT. That is great. I thought that it's impossible. Because my 2 switches ar not support stacking and my 1Gbps LAN cards not support 802.3ad, my best bet I think to use balance-alb (mode 6). I will asure...

    Nic's bond for CEPH

    Doing VLAN's the performance of the network won't be affected? I don't tell that I will have 2 switches. One cable from the NIC-A goes to Switch-A and the NIC-B goes to Switch-B. This is for loadbalancing and fail-over. Do I understand correctly that I don't need to configure anything on both...

    Backup speed KVM vs LXC

    Thanks. I plan that mechanical HDD will contain millions of small files after 3 years. So here is a dilemma, or to have LXC with better performance because servers are quite weak, but have trouble with backup/restore. Or use KVM, and always have lower performance and quicker restore procedure...

    Nic's bond for CEPH

    I want to bond NIC-A and NIC-B in order to have performance and fail-over. This bonded interface will be used for CEPH public and private networks. So now the question, can I create CT or VM from Proxmox GUI and add a network card NIC-A for CT's and VM's for networking?

    Backup speed KVM vs LXC

    LXC has more performance comparing to KVM. But as I read LXC container backup is a quite slow, because it is like a type of the file system backup. I mean you need to copy like all the files with LXC and KVM is just a single huge file. Could someone tell me if I backup 2TB container of very...

    Ceph, Proxmox cluster. OS on single disk or RAID?

    Ok, understood. Thanks for your time.

    Ceph, Proxmox cluster. OS on single disk or RAID?

    I see that you understand what you are talking. This is very useful information.Each server will have 2 networks cards. I read that Ceph needs to cards for internal and public traffic. So I safe here I guess. Would you suggest to go with LXC or KVM on Ceph, knowing that each server is with only...

    Ceph, Proxmox cluster. OS on single disk or RAID?

    Ok, thanks for the answer. I slowly get the whole picture. I didn't think that lower grade SSD is so low on IOPS. I also noticed that XFS, according to your document will use 50% of free RAM. Actually my servers are quite old and each has only 16GB RAM. Investing in better network cards will...

    Ceph, Proxmox cluster. OS on single disk or RAID?

    Hi, for each server I have 2 HHD and 1 SSD disks. I wonder do I really need to put Proxmox OS on ZFS raid1 with two disks or just use a single HDD disk, because in HA cluster environment in case of server (virtual machine) failure another server (VM) automatically will take place? So this...

    Proxmox cluster - disk layout for ceph

    Thanks for the answer. I plan to use onle 1 OSD, maybe up to 2 OSD and that is it. On every node I will use 1 guest (a single OpenVz or KVM machine, please advice me which is not so resource hungry on CEPH). This machine will have 10-12GB of RAM, so I can dedicate 6-4GB for the CEPH, Proxmox...

    Proxmox cluster - disk layout for ceph

    Hi, I plan to build my first ceph cluster and have some newbie questions. In the beginning I will start with 5 nodes, and plan to reach 50 nodes. Those nodes quite old (CPU E3,16GB RAM, 2x1Gbps network), so I think to gain the performance in adding more nodes but not upgrading RAM or CPU. I...
