The general view in the industry is that 400G is moving towards large-scale applications, while 800G mostly appears in discussions of large-scale cloud computing scenarios, and is still an object of observation for most medium-sized computer rooms. But the lessons for gear evolution are the same: if you prepare the foundation in advance, subsequent renovations will be much easier.

Leave some room for space and power first

The industry generally expects that the single power consumption of the new generation of high-speed modules will be higher. When expanding, cabinet power distribution and cooling margins should be reviewed simultaneously, and the filling rate of the cabling rack should be reserved to leave cabling space for the next link. The server side can be planned hierarchically according to the purpose and configured with high-throughput nodes.PCI-EX16 100G single optical port fiber optic network card (Intel E810 chip), general nodes use the 25G gear to avoid idleness caused by synchronous gear shifting in the entire domain.

Cabling and labeling systems should span different levels

• The polarity and labeling rules of jumpers are unified. Links at different speeds do not need to be manually identified. Changing speeds does not require changing the system.
• Reserve spare ports on ODF and distribution frames and register their locations, and the terminal data will be archived with the project.
• The port correspondence table is updated in real time with construction, so there is no need to start from scratch for the next batch of capacity expansions.

First clean the existing 100G pipe

Whether the evolution can go smoothly depends more on whether the existing links are clean. It is recommended that the light receiving power, DDM readings and bit error conditions be included in the ledger, and the high-risk segments should be repaired first, and then new gears can be discussed. Only after the baseline data is entered, there will be comparison standards for subsequent gear changes. EB-LINK modules are tested one by one during shipment, and the measured data can be archived into the ledger for baseline purposes.

Cabinet space, power and accounting can be done now.
