My "standard-disk" is currently the Intel D3-S4510 series. Can you recommend me any other disk, that offers comparable performance...

    Hi! I am just a bit confused on how to configure STP on a port facing to my ISP. My fear is, that the ISP could send BPDUs and so, he could change my STP-topology. Option 1: Disable STP on that port --> In that case: What happens, if BPDUs are received? Will they be dropped or forwarded in...

    Understanding DHCP-relay

    Hi! For hours now, I am trying to really understand how to configure: - a central Linux DHCPd-server - satellite DHCP-relays ...but I still did not reach my goal... The main problem is: - How does DHCPd "assign" the right subnet-zone to the relay-agent? If the DHCPd-server owns an interface...

    Hi! I need to setup a server as veeam-backup-storage. It will have 38 10TB drives, but I am not sure about the layout, as I did not use a ZFS system without anything else than striped mirrors. What would you recommend? It would be good to have a sequential read-performance of >4-5 Gbit/s 3...
