Swift/Deploy Plan - R720xds in tampa
From Wikitech
Draft, edit at will
Current status
- Currently replaced: ms-be6,7,8,10
- Hosts with disk issues (so they should be replaced next): ms-be5,11,12
- Other hosts with ssds: ms-be9
- The rest: ms-be1-4
Proposed schedule
Pushing our luck a little bit, we can go from 33 weight for the object rings to 66 in 3 days and from 66 to 100 in another 4. This is a compressed schedule, it really doesn't let network traffic to the new hosts settle down completely, but it will let us get the new boxes in and the old ones shipped.
We should do these no more than two at a time. Schedule for first deployment in cluster with 33% weight:
- ms-be5 and ms-be11 on Thursday Nov 29
- ms-12 and ms-be9 on Dec 3 or 4
- ms-be1 and ms-be2 on Dec 7
- me be-3 and ms-be4 on Dec 12
This schedule will be adjusted (shorter or longer) as we see how the cluster behaves.
Logistics
What is our deadline for returning the C2100s?
