Features
Data Center 10GE Access Switch RG-S6250-48XS8CQ
10GE high-density access switch with 10GE/100GE downlink ports and 100GE uplink ports backward compatible with 40GE 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
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.
M-LAG
M-LAG technology implements load sharing between links and improves link reliability. The independent control plane supports independent device upgrade, realizing service upgrade within seconds and consistent user experience.
VSU
VSU technology can virtualize multiple physical devices into one logical device, simplifying network configuration and architecture, eliminating loops, and improving reliability.
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.
