Abstract: A SDN controller receives a packet related to flow which is uploaded from a vSwitch, and if source address and destination address of the packet related to flow belong to different physical servers, the SDN controller may distribute a source flow table entry to the vSwitch which uploads the packet related to flow. Wherein action corresponding to the source flow table entry may include: for a traffic packet whose destination address matches the destination address, by using MAC address of a vSwitch connected with the source address as outer layer source MAC address and using MAC address of a vSwitch connected with the destination address as outer layer destination MAC address, encapsulating the traffic packet into a packet having double layer VLAN tags, and forwarding the packet from a port leading to a physical network card of the physical server where the vSwitch is deployed.

Abstract: When monitoring that a host migrated, a software defined network (SDN) controller may actively detect a port located by the host. Besides, when detecting the port located by the host, the SDN controller may bind the host to the port where the host is located, so as to limit migration of the host. When not detecting a port located by the host, the SDN controller may also block packets from the host.

Abstract: Examples disclosed herein relate to processing transaction logs for storage nodes. Multiple nodes manage transactions for storage units including transaction logs. A node assumes control over a set of storage units and blocks host access requests to the storage units. Transaction logs are processed to determine a subset of the set to perform recovery for. In this example, the subset of storage units are locked. Host access requests are resumed.
