Abstract
A storage processor of a set of virtual-machine-implemented storage processors (SPs) of a virtual storage appliance (VSA) is operated to avoid potential mis-communications among non-peer SPs in a virtualized environment having multiple VSAs. An operating method includes receiving a peer-SP identifier that uniquely identifies a peer storage processor of the VSA in network packets sent by the peer storage processor via an internal inter-SP network. The peer-SP identifier, which may be a machine-level network address such as a MAC address, is used to configure a network firewall to accept peer-SP packets and reject non-peer-SP packets from the internal inter-SP network. The network firewall is subsequently operated as configured to accept the peer-SP packets for delivery to the main operating logic of the one storage processor and to reject the non-peer-SP network packets.
