Abstract: A virtual machine (VM) system includes a network, hosts that are able to communicate over the network, a storage cluster of nodes made up by the hosts, and VMs running on the hosts. As part of the storage cluster, the nodes pool their storage devices into a clustered datastore shared across all the nodes. The VMs are stored in the clustered datastore. Two of the nodes take roles of a reflector node and a backup reflector node. The other nodes, excluding the reflector node but including the backup reflector node, are configured to establish unicast connections over the network with the reflector node. The nodes in the storage cluster are configured to communicate clustering service information over the unicast connections.

Abstract: Example methods are provided for a host to perform packet processing using a service chain in a software-defined networking (SDN) environment. The method may comprise establishing a datapath between a first virtualized computing instance and a second virtualized computing instance in the service chain, the datapath bypassing a forwarding element to which the first virtualized computing instance and the second virtualized computing instance are connected. The method may also comprise: the first virtualized computing instance obtaining a packet that requires processing by the service chain, and performing packet processing according to a first service. The method may further comprise: the second virtualized computing instance obtaining the processed packet via the datapath, and performing packet processing according to a second service.
