IP Scheme

The goal is to create a scheme which eases daily life. IP mapping should be more or less straightforward and extensible. For servers look at:

Management Network

For this we will utilize parts of the RFC1918 172.x.y.z/12 network. Thus, please use a netmask of and NOT! Note that is special (legacy, historic reasons :()...

Data Network

For this we will utilize a 10.X.Y.Z/8 network (also RFC1918). The corresponding scheme for the host names can be found in hostnames .

The first free octet will tell what kind of thing we are talking about:

type Octet X Octet Y Octet Z resultSorted ascending example
Compute node 10 hundreds singles 10.10.H.S n1123 =>
GPGPU 12 0 singles 10.12.0.S gpu001, gpu054
Test Nodes 11 0 singles 10.15.0.S gpu01 =>
file server (Linux) 20 10 singles 10.20.10.S d31 =>
file server (Sun ATLAS.Internal.X4500) 20 20 singles 10.20.20.S s09 =>
head nodes 20 30 singles 10.20.30.S h03 =>
internal nodes 20 40 singles 10.20.40.S  
special purpose nodes 20 50 singles 10.20.50.S e.g. einstein-dl, einstein-db
TRX switch 25 0 singles 10.25.0.S rack05 =>

By Computer Class

This section is only for "classes" of computers, i.e. not individual servers
