Build your network the way real data centers do. Traffic now shares every parallel path, so pairs of routers, firewalls and spines all carry their share. A 100G firewall guards a big hall’s edge, servers get 100G cards, clients’ servers talk to each other across your switches, and a management network brings any server’s console, and its power switch, to your desk.
New
- Firewall 100G. From National: two pairs of 100G QSFP28 ports for the edge of a big hall, outside to your core routers and inside to your spines. Two side by side share the load and cover for each other.
- Dual 100 Gb card. From Regional: two QSFP28 ports for a GPU or HPC server, cabled to a 100G switch. With both cabled, it gets 200 Gb.
- The management network. Every server’s MGMT port is a real port now. Cable it to a switch that leads to a router (or into the router), and the server shows in Server Consoles at the desk as one on a KVM does: its screen, updates, hang alerts and watchdog. You can switch it on and off from there too.
- Traffic between a client’s servers. Clients on several servers send traffic between them as well: storage replicating, databases, HPC nodes swapping results (mining clients don’t). It crosses the switches between them, never your lines. GigBid shows how much each offer sends, a client’s card checks it, and NetOps shows it server by server. If the links between their switches are full, or the servers can’t reach each other, the client misses its promise, so keep its servers together or join their switches with fast links.
- Building a fabric. A new Handbook article on laying out a big hall’s network: two routers, a firewall pair, spines, leaves, servers on two switches, and a management network.
Changed
- Traffic shares every parallel path. Where there’s more than one equally short way out, traffic splits over them by link speed, as in a real fabric. Two routers each carry their share over their own lines, firewall pairs and spines share the load, and a server cabled to two switches uses both links. When one fails, the others carry everything.
- Clients you’d already signed aren’t held to the traffic between their servers until they renew.
- Server Consoles (the KVM Console, before) opens once you have a KVM switch or a cabled MGMT port, and lists servers on the management network apart from those on KVM switches.
- In a slid-out server, the 100 Gb card and dual-rotor fans have models of their own.
- Saves from earlier versions load. In a shared game, everyone needs this version.
