We have had a major outage
We have had a major outage because of a combination of network outage and the way we designed our environment. Working with Cisco and Pure support to get to the exact details, but main issue is: Our design has ESXi hosts only connected to Pure array in DC1 and we have pods that replicate SYNC to DC2. During network maintenance there was a planned core switch failover that caused a longer outage then expected, which made the mediator unavailable and the latency for the preferred site too high. This all caused the pods to become unavailable on our preferred site and "switch" over the non-preferred site. We're still looking into the details, but I'm also searching for a possible work around during future core maintenance. For that, the question I have is if it is possible to automate (RestAPI / Powershell) the sync of pod's to pause, to prevent failovers during network maintenance and of course enable it again later on.Solved26Views0likes4Comments
