25GE Data Center Access Switch RG-S6510-48VS8CQ

8 x 25GE SFP28 ports and 8 x 100GE QSFP28 ports, delivering line-rate forwarding capacity
32 MB buffer and advanced buffer scheduling mechanism, providing fast data processing and easily coping with burst traffic

Hardware-level Redundancy, Ensuring Service Continuity

Hot-swappable redundant power modules

Hot-swappable redundant fan modules

Power modules in 1+1 redundancy mode, and failover in seconds, providing nonstop services

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.

VXLAN Tunneling Technology, Achieving Unlimited Data Transmission and Flexible Resource Allocation and Scheduling

VXLAN technology creates virtual tunnels on an IP network by building a virtual Layer 2 network, implementing cross-region and cross-DC data migration, and flexible resource allocation and scheduling. The switch supports EVPN VXLAN to enhance the number of tenants, meeting requirements of identification and isolation between different networks on a large scale.

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/gRPC/sFlow/SPAN 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.
