As you heard in today's project meeting, IT's consolidation of data centers will save us $900K/yr!! Yay! There will be some impact to the build farm as the move actually happens, and this posting outlines them.
The impact to engineering will be a slight capacity reduction in the build far for the first part of every week starting May 19 and continuing through the end of June. We believe no scheduled tree closures will be needed. However, sheriffs may need to slow down merges and/or close trees if the load becomes excessive. Thanks for your patience and understanding during this move! -- Hal for everyone in IT & Engineering involved in the move! The longer story: We have 20 racks of equipment to move, which impacts almost all build pools. We've scheduled machine moves to minimize the impact to any given platform. The goal is to reduce capacity evenly across the board, and thus be able to leave the trees open. (This also spreads the load across all the imaging servers, as each machine needs to be rebuilt in the new data center) The moves start on Monday, May 19, and will continue for approximately 6 weeks. The major impact is scheduled for Monday, and the "most critical" machines should be back on line Wednesday morning. Data Center Operations, Release Operations, and Release Engineering have been planning for the move for several months. There are approximately 20 racks of equipment to move. The plan is to move key machines in batches, spread across functional areas. That is, we'll degrade all platforms slightly, rather than take a single platform offline. We don't believe there will be any need to close the trees with this approach, although sheriffs may not merge as often. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
