DNS scheme
The internal domain is atlas.local (managed by us), external domain might be atlas.uni-hannover.de (managed by RRZN)
Nodes
Nodes have three networking interfaces:
eth0 will be known by two names, e.g. mg0123 and ipmi0123 for the management network and the
IPMI card respectively.
eth1 will be known only by n0123.
Thus the FQDN of a node may be n0123.atlas.local
Linux storage nodes
These nodes have in total 6 network interfaces, i.e.
eth0 and eth1 (data network): d04a and d04b where the may exist an alias for d04==d04a, i.e. d04.atlas.local
eth2 and eth3 (external network): d04a and d04b where the may exist an alias for d04==d04a, i.e. d04.atlas.uni-hannover.de
IPMI: ipmi04.atlas.local (four digits for nodes, two digits for data server)
Areca: raid04.atlas.local
Linux head nodes
These nodes have in total 4 network interfaces, i.e.
eth0 (data network): h3.atlas.local
eth1 (external network): h3.atlas.uni-hannover.de
IPMI: ipmi3.atlas.local (four digits for nodes, two digits for data server, single digits for head nodes)
Areca: raid3.atlas.local (single digits for head nodes)
X4500
These boxes will have 6 network interfaces, but not all are used:
10 Gb/s ethernet (data network): s08.atlas.local
1 Gb/s etherner (external): s08a.atlas.uni-hannover.de, s08b.atlas.uni-hannover.de, ... (if needed)
ILOM: ilom08.atlas.local
