Data Center 100GE Access Switch RG-S6520-64CQ

100GE high-density access switch with 10GE/25GE/100GE downlink ports and 64 x 100GE uplink ports housed in a 2 RU enclosure for adaptation to different
scenarios, Large buffer and advanced buffer scheduling mechanism, providing fast data processing and easily coping with burst traffic

Cross-device Link Aggregation, Implementing Device-level Redundancy, Flexible Networking, and High Reliability

De-stacking

M-LAG

VSU

De-stacking technology logically aggregates multiple switches through LACP to allow servers on the same network segment or on different network segments to communicate. This eliminates the need to synchronize data between switches, without affecting service transmission.

PFC- and ECN-based Lossless Ethernet with High Throughput and Low Latency in RDMA Scenarios

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.
