First, HW. Get two Cisco Nexus 3064PQ (they typically go for $600-700 for 48 10G = ports) and two Intel X520-DA2 per server. Hook up each port of the Intel cards to each of the Nexuses, getting a = full redundancy between network cards and switches. Add 4x40G DAC cables between the switches, setup 2 as VPC peer-links, 2 = as a simple L2 trunk (can provide more details as why if needed). Use ports 0 from both NICs for ceph, ports 1 for VM traffic. This way = you get 2x10 Gbps for Ceph only and 2x10 Gbps for everything else, and = if you loose one card or one switch, you still have 10 Gbps for each. The benefits? With default configuration, your data lives in 3 places. = Also, scale out. You know the expensive stuff, hyperconverged servers = (nutanix and such) ? You get that with this. The performance is wild, just moved my customers from a proxmox cluster = backed by a TrueNAS server (full flash, 4x10Gbps) to a 3 node cluster of = AMD EPYC nodes with Ceph on local SATA SSDs and the VMs started flying. Keep your old storage infrastructure, whatever that is, for backups with = PBS. YMMV Regards, ic
