    Best practice - zfs (ssd, optane, spinning disk)

    Correct. The speed should improve significantly. For Raid6 you can expect x4 read speed and x1 write speed (where x1 is speed of 1 drive). For Raid 10 you can expect x6 read speed and x3 write speed, meaning +50% read speed and +200% write speed compared to Raid6. What you lose is 2TB of space...

    WANT TO CONVERT A PHYSICAL MACHINE TO VIRTUAL MACHINE

    Hey! This is what Google throws as first result for backing up CentOS: https://serverfault.com/questions/120431/how-to-backup-a-full-centos-server. What is a more interesting topic - how is the system being used. I expect that you have a stack that serves a particular purpose. Maybe it'd be...

    [TUTORIAL] Configuring Fusion-Io (SanDisk) ioDrive, ioDrive2, ioScale and ioScale2 cards with Proxmox

    @Psilospiral, for now, yes. But the whole purpose is to make them reconsider. The changes to the drivers should be minimal, so it's a matter of principle.

    change server question.

    Hey! Keep in mind that the hardware settings may differ on different servers. For instance, your CPU type needs to match the system and so are the flags if any are set. I think it should be of type kvm64 or host for CPU, but if it's different - i'd look into changing the settings prior to...

    Sockets vs Cores vs vCPUs

    Hey! Socket is the physical slot for a CPU. It matters if, for instance, you need NUMA (allocated RAM per CPU, which speeds up computation). Core - is the physical core a CPU has. Here it gets a bit confusing - within Proxmox the number of cores equals the number of threads, so if your CPU...

    Server build for small office

    You can find a quick summary about RAID levels here: https://calomel.org/zfs_raid_speed_capacity.html In a nutshell, you need at least 4 drives for RaidZ2 and going with RaidZ1 on 10TB drives seems like a recipe for disaster. You can either go with: 2 drives in Raid0 for speed purposes, while...

    Best practice for Proxmox self-backup

    If i were to add to this discussion, i personally think it's not the most appropriate way to address the Proxmox backup. I'd separate the backup part into 2 aspects: backing up the configs (storage, cluster, network, VMs, containers, backup cron) restoring the OS I see that the optimal...

    Proxmox on remote server: security best practices?

    @mdbraber, The gist of 3) is using a VPN to connect to your server. The main difference i see is traffic limitation and encryption, rather than just limitation. You can attempt achieving a similar effect with SSL, but SSL does not encrypt non-http traffic. So, for instance, if you were to...
