Networking
One of the most important components of JINR and MICC providing access to resources and the possibility to work with the big data is a network infrastructure.
High-speed reliable network infrastructure with a dedicated reserved data link to CERN (
LHCOPN).
LHCOPN composed of many 10 Gbps links interconnecting the Tier-0 centre at CERN with the Tier-1 sites fulfilled its mission of providing stable high-capacity connectivity
The network architecture of the Tier-1 at JINR was constructed with
a double route between the access level and the server level
Each server have access to the network segment by
two equivalent
10Gbps links, with a total throughput of
20 Gbps.
The connection between the access level and distribution level has
four 40 Gbps routes, which, consequently, allow data transmission 160 Gbps, the oversubscription being 1:3.
The Tier-1 network segment is implemented on the
Brocade VDX 6740 capable of data communication with more than
230 10-Gigabit Ethernet ports and
40 Gigabit Ethernet ports.
The series comprises models with optical and copper
10 Gbps ports and
40 Gbps uplinks
