Top-of-rack switch firmware, rows A–B — ZRH

计划安排

The top-of-rack switches in rows A to B of ZRH receive a firmware update. Each switch reloads once, which interrupts the network for the machines in its rack for about 90 seconds. Racks are done one at a time. Running workloads are not affected, only reachability during the reload. The interruption is counted against the SLA of the affected machines even though it is announced.
