SFP28 vs. SFP+ vs. QSFP28

The most prevalent Ethernet migration path until recently is accepted as 10G-40G-100G, however, the advancement in networking technology has ushered in a new alternative-25G Ethernet, indicating the lasted upgrade path could be 10G-25G-100G, or 10G-25G-50G-100G potentially. These migration solutions enable more efficient use of hardware and a more valid upgrade path to 100G. Optics like […]

Leaf-Spine Topology and Its Construction Examples

For many years, data centers have been built in three-tier architecture, comprised of the core, aggregation and access layers. But with the data center consolidation, virtualization, hyper-converged systems springing up, the way data flows is shifting from traditional north-south to east-west inside data center. As the volume of east to west traffic increases, network bottlenecks […]
