Huawei's end-to-end active-active data center solution is divided into six logical layers, namely, storage, computing, application, network, transmission, and security layers. Which are key points in designing these layers? (Multiple Choice)
- The security layer uses Huawei USG series to provide security protection functions such as FW and IDS for data centers.
- The storage layer uses the FastWrite function to reduce two round trips to one for each standard write I/O, thereby improving the write performance.
- The computing layer uses virtualization platforms such as FusionSphere and VMware to provide cross-data-center clustering, thereby enabling multiple mission-critical applications to run in active-active mode.
- The transmission layer employs optimization approaches such as dispersion compensation to ensure the minimum latency on the transmission layer.
