  • hello abhagat - i do not expect PDL when a single uniform activecluster array (or site) goes down. the healthy array should continue to serve IO after a brief pause. as jjozelj mentioned, a race to the mediator will likely occur, but that should not trigger a PDL. one thing i'd like to note is that both latency based PSP and RR IOPS 1 are supported from a Pure perspective with ESXi 6.7U1 and later. this is definitely something worth getting a support case open with Pure support on (and possibly VMware support) to figure out what happened and why. ```In Uniform configurations, enabling this setting is less important since the volume is presented via two arrays, and full PDL would require the volume to be removed from both FlashArray.``` https://support.purestorage.com/Solutions/VMware_Platform_Guide/User_Guides_for_VMware_Solutions/ActiveCluster_with_VMware_User_Guide/vSphere_Metro_Storage_Cluster_With_ActiveCluster%3A_Configuring_vSphere_HA#Datastore_with_PDL|https://support.purestorage.com/Solutions/VMware_Platform_Guide/User_Guides_for_VMware_S[…]rage_Cluster_With_ActiveCluster%3A_Configuring_vSphere_HA
