The asw-a/b/c rows refresh in eqiad will add 1 more 10G switch (48 ports) per row. Bringing the total number of 10G ports in eqiad from ~432 to ~528. Switch cycle is ~5 years, and row D will most likely be re-trofitted with an extra 10G switch in the future.
This task is to track the 1G->10G upgrades or servers, so 1/ teams that need 10G are aware that we have the capacity, and 2/ we don't exceed that capacity
Talking with various teams in charge of servers usually heavy in data last August (when planning the switch upgrade) I noted those potential evolutions.
As this is from 7 months ago it's now mostly a baseline and should be update with more accurate numbers.
| Service | Evolution (5y) | Note |
| --- | --- | --- |
| Databases backups | +10 | |
| Media storage backend | +6/8 per year (40 in 5 years) | |
| Cloud | +8/10 (over 2 years) | |
| Traffic | decrease | |
| Memcache | no planned changes | |
| Hadoop | +10/12 nodes/y (no need for 10G) | |
| Kafka | max doubling (probably not 10G) | |
| Kubernetes | pretty sure wont need 10G | |
| Ganeti | | Peaks close to 1G |
| Backups | | |
| Elasticsearch | | Peaks close to 1G |
