Proof of Concept Reduce top of rack switches costs 10/40GSW: 10/40Gigabit Ethernet Switch, SV: Server Top of Rack SW Aggregation SW Paper: How to build and manage a large scale switchless server clustering, Naoto MATSUMOTO,IOT28, 2015 / The Special Interest Group on Internet and Operation Technology (SIG-IOT) / Information Processing Society of Japan.
- 3. How does it works Using OSPFv3 Link-state advertisement for server clustering Quagga or another routing daemons
- 4. How to build it (CentOS7) # yum install -y quagga iptables-services # nmcli con mod eth0 connection.autoconnect yes # nmcli con mod eth1 connection.autoconnect yes # nmcli con mod eth2 connection.autoconnect yes # nmcli con mod eth3 connection.autoconnect yes # echo "net.ipv6.conf.all.forwarding = 1" >> /etc/sysctl.conf # cp -p /etc/quagga/zebra.conf /etc/quagga/ospf6d.conf # setsebool -P zebra_write_config 1 # systemctl mask firewalld # systemctl disable ip6tables # systemctl enable ospf6d # systemctl start ospf6d # vtysh # configure terminal # router ospf6 # router-id 10.0.0.16 # redistribute connected # area 0.0.0.0 range fd50:d026:7eee::/48 # interface eth0 area 0.0.0.0 # interface eth1 area 0.0.0.0 # interface eth2 area 0.0.0.0 # interface eth3 area 0.0.0.0 # interface lo # ipv6 address fd50:d026:7eee:16::16/64 # end # write # quit # reboot Routing daemon setup OSPFv3 configuration
- 5. Fast OSPFv3 Link Update TIPS # uname -sr ; cat /etc/redhat-release Linux 3.10.0-123.13.2.el7.x86_64 CentOS Linux release 7.0.1406 (Core) # vtysh # configure terminal # interface eth0 # ipv6 ospf6 hello-interval 1 # ipv6 ospf6 retransmit-interval 2 # ipv6 ospf6 dead-interval 3 # interface eth1 # ipv6 ospf6 hello-interval 1 # ipv6 ospf6 retransmit-interval 2 # ipv6 ospf6 dead-interval 3 # interface eth2 # ipv6 ospf6 hello-interval 1 # ipv6 ospf6 retransmit-interval 2 # ipv6 ospf6 dead-interval 3 # interface eth3 # ipv6 ospf6 hello-interval 1 # ipv6 ospf6 retransmit-interval 2 # ipv6 ospf6 dead-interval 3 # end # write # quit OSPFv3 update interval adjustment

- 7. Network Durability Using OSPFv3 Link-state updates for re-route and failover failover
- 8. Backward Compatibility Translation,proxy and tunneling for IPv4 backward compatibility 10/40GSW: 10/40Gigabit Ethernet Switch, SV: Server IPv4 IPv6 NAT, Proxy, L2TPv3 ..etc
- 9. 19' Rack Design Reduce networking cables costs 10/40GSW: 10/40Gigabit Ethernet Switch, SV: Server
- 10. Conclusion "An Easy way to build a server cluster without top of rack Switches" is ... - Reduce top of rack switches & cables costs. - Lightweight and simple configuration. - High network durability. - Good IPv4/IPv6 backward compatibility.
