Ii. Общий обзор

There are two main stacking connection methods: stacking card stacking and service port stacking. Stacking card stacking requires the purchase of dedicated stacking cards and stacking cables. Although this method is more expensive, it provides higher stability and transmission efficiency. Service port stacking, on the other hand, is more flexible, allowing users to use standard Ethernet cables or fiber optics for stacking. This method does not require additional hardware investment and is suitable for scenarios with limited budgets or temporary network expansion.

Stacking Card Stacking and Service Port Stacking: Specific Environments Where the Two Methods Apply

I. Suitable Environment for Stacking Card Stacking

Stacking card stacking connects switches through dedicated stacking cards (e.g., ES5D21VST000(1) and stacking cables, offering high reliability and performance. It is suitable for the following scenarios:

1. Enterprise Core or Aggregation Layers: In scenarios requiring high performance and reliability, such as core or aggregation layer switches in enterprise data centers, stacking card stacking enables connections with high bandwidth and low latency.

2. High-performance Requirement Scenarios: Ideal for environments that need to handle large volumes of data traffic, such as financial services and cloud computing centers, stacking card stacking provides higher bandwidth and lower latency.

3. High-density Access Scenarios: Under high-density access requirements, stacking card stacking can rapidly expand port numbers to meet the demands of large-scale user access.

4. Data Center Internal Networking: By employing stacking card stacking within data centers, it simplifies network architecture, enhancing overall performance and reliability.

II. Suitable Environment for Service Port Stacking

Service port stacking uses service ports (such as SFP+, GE, etc.) for stacking connections without needing dedicated stacking cards, making it flexible and cost-effective. It is applicable in the following scenarios:

1. Small and Medium Enterprise Networks: Within SME networks, service port stacking allows for flexible expansion of port numbers to meet access needs while reducing costs.

2. Campus Access Layers: At the campus network access layer, service port stacking enables virtualization of multiple switches, simplifying management and improving reliability.

3. Flexible Networking Requirements: Suitable for scenarios requiring flexible networking, such as multi-story buildings or long-distance networking, service port stacking facilitates extended-distance stacking connections.

4. Rapid Deployment Scenarios: Supporting configuration-free stacking (like the S5700 series), service port stacking is ideal for rapid deployment scenarios where complex configurations are unnecessary to establish a stacking system.

5. Cost-sensitive Scenarios: Applicable in budget-limited settings, avoiding the purchase of dedicated stacking cards through service port stacking reduces initial investment costs.

III. Conclusion

1. Stacking Card Stacking: Suitable for scenarios demanding high performance and reliability, such as enterprise cores and data centers.

2. Service Port Stacking: Best suited for scenarios requiring flexibility, cost-effectiveness, and quick deployment, like small and medium enterprises and campus access layers.

Selection of Stacking Methods Requires Comprehensive Consideration Based on Actual Needs (Such as Performance, Cost, Deployment Complexity, Etc.)
