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.
|Databases backups/provisioning service||+10|
|Media storage backend||+6/8 per year (40 in 5 years)|
|Cloud||+8/10 (over 2 years)|
|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|
|Elasticsearch||Peaks close to 1G|
