CERN-CNAF Collaboration meeting
(Topic 1.4)
Edoardo Martelli (CERN)
Vincent Ducret (CERN)
Marian Babik (CERN)
Paolo Veronesi (INFN Bologna)
Riccardo Veraldi (INFN CNAF)
Stefano Zani (INFN CNAF)
Introductory presentation by CNAF
Common brainstorming on various aspects to be considered for a datacenter network design
CERN anticipated some aspects being studied for the evolution of the current datacenter and network implications
Information exchange on networking solutions on the following subjects are considered useful
-
Cabling systems
-
-
Type of fibres to be used
-
Type of connectors
-
Network Topology
-
-
Edge-Core
-
Spine-Leaf
-
VXLAN support network side (Vxlan managed at Core level, Vxlan managed at TOR level ?)
-
Virtualization sistems integration
-
-
Open Stack deployments and implication on the network infrastructure
-
K8s implications on network design ?
-
Network Automation Tools
-
-
Open Source/Proprietary (what it si needed and what’s available)
Next subject to focus in next meeting are essentially the 4 point mentioned.
CERN will try to elaborate some slide on some of the topics 1 to 4.
CNAF will collect more detailed informations on the sizing of the real parameters of next network and from its tech track activity to share
Possible area of interaction for the future .
Some other possible fields of future collaboration could be relative a possible DCI interconnection CERN-CNAF to be correctly addressed and finalised proposed by CNAF (Future)
Next meeting: 27-May at 16:00 (Zoom)
If there will be some aspects to expand in particular detail, starting from the next meeting we could define different format with more frequent meeting focused on a specific subject involving all the people interested and competent on the specific item.
