Dear All, This is a personal reminder for the Ceph Science meeting jointly organized by the person in cc on this message. This month we will be having a Ceph science/research/big cluster call on Tuesday July 29th instead of Tuesday 22nd as per ceph.io calendar. If anyone wants to discuss something specific they can add it to the pad linked below. If you have questions or comments or simply don't want to receive further announcements, you are most welcome to contact us. This round Tom Byrne from STFC will be presenting a short investigation about power and carbon cost of Ceph storage.

Updates, outages, features, maintenance, etc. There is no single set presenter for the length of the meeting, but it is somewhat moderated to keep the conversation flowing.
