EB-LINK recently updated its data center high-speed interconnection solution. Focusing on the construction scenarios of Spine-Leaf two-layer architecture and common three-layer architecture, it integrates optical modules, fiber optic network cards, DAC/AOC high-speed cables and fiber jumpers into a directly comparable selection list, making it easier for projects to configure links at one time.

Two-tier and three-tier architectures are applicable respectively according to traffic flow.

The traditional access-aggregation-core three-tier architecture is suitable for scenarios where north-south traffic is the main component. However, the proportion of east-west traffic within the data center is increasing year by year, and the problems of delay superposition and bandwidth convergence in the three-tier structure will become more prominent. The updated plan provides clear division suggestions: Spine-Leaf is preferred for computing and storage interconnection domains, and only two hops are forwarded at any two points; the core layer is reserved for egress and inter-building aggregation to avoid waste caused by one-size-fits-all transformation of the entire network. Latency-sensitive financial transactions and HPC businesses will especially benefit. For campus computer rooms with only hundreds of virtual machines and mainly egress traffic, three layers are still sufficient when the budget is limited.

Manifest aligns models by link role

• Leaf to server access: recommended25G DAC high speed cable, the lowest cost and power consumption in short-distance scenarios in the same cabinet
• Spine uplink and short distance between buildings: Available100G DAC high speed cable, replace the single-mode module with long distance
• The matching jumper can be selected in LC/SC form according to the panel interface, and the length can be reported at one time

Code writing customization and spot matching

The optical modules in the list can be coded for free according to switch brands such as Cisco, Huawei, H3C, Ruijie, etc., and will be shipped after testing one by one; the complete comparison table can be found atData center high-speed interconnection solutionView the page and the list also provides recommended port ratios based on the number of cabinets to avoid secondary cutovers caused by insufficient uplink port reservations.
