Zero-trust dynamic discovery in provided by identifying a plurality of endpoints, including targets and initiators, connected to a software defined network, wherein the targets are provided on the software defined network according to a network addressable memory standard that lacks a native discovery service; grouping the targets into a plurality of target groups and the initiators into a plurality of initiator groups; and in response to receiving a discovery request from a given initiator grouped in a given initiator group of the plurality of initiator groups, returning addressing information for a target group of the plurality of target groups associated with the given initiator group in a security policy configuration for the software defined network.

Embodiments provide for mitigating priority flow control deadlock in stretch topologies by initializing a plurality of queues in a buffer of a leaf switch at a local cluster of a site having a plurality of clusters, wherein each queue of the plurality of queues corresponds to a respective one cluster of the plurality of clusters; receiving a pause command for no-drop traffic on the leaf switch, the pause command including an internal Class-of-Service (iCoS) identifier associated with a particular cluster of the plurality of cluster and a corresponding queue in the plurality of queues; and in response to determining, based on the iCoS identifier, that the pause command was received from a remote spine switch associated with a different cluster than the local cluster: forwarding the pause command to a local spine switch in the local cluster; and implementing the pause command on the corresponding queue in the buffer.
