Features
Data Center 100GE Core Switch RG-S6920-4C
Four service slots, with 100GE and 400GE line cards, allowing for easy expansion and satisfying future bandwidth expansion needs
Various ports, up to 128 × 100GE ports or 32 × 400GE QSFP-DD ports., which are fit for different scenarios of data center networks
Hardware-level Redundancy, Ensuring Service Continuity
Hot-Swappable Redundant Power Modules
Power modules in 2+2 redundancy mode, failover in seconds, and power module replacement without network interruption, providing double protection for links
Hot-Swappable Redundant Fan Modules
Fan modules in 5+1 redundancy mode, intelligent fan speed adjustment, and highly-efficient heat dissipation, building low-carbon data centers
Lossless Ethernet with RDMA E2E Communication and Zero Packet Loss
With RDMA technology, data does not need to be handled by the CPU during device communication. This reduces the CPU burden
and effectively solves the network latency problem.
PFC+ECN, intelligent data exchange, and packet loss prevention, ensuring lossless data transmission
Telemetry-based Network Monitoring and Automated O&M, Making Management Simple and Efficient
The switch enabled with telemetry provides clear data status and hierarchy.
The switch uses the push mode to proactively collect and push information and to provide sub-second-level network monitoring in real time,
making network management more efficient and accurate.
