  1. Virtualization Infrastructure Administration Network Jakub Yaghob

  2. vSphere networking • Network services for hosts and VMs • Connecting virtual machines to the physical network and to each other • Connecting VMkernel services (such as NFS, iSCSI, or vMotion) to the physical network

  3. application application application operating system operating system operating system vSphere networking overview Virtual NIC Virtual NIC Virtual NIC Physical NIC physical switch ports External World

  4. vSphere port group

  5. vSphere port group • Port group • Aggregates multiple ports under a common configuration • Network label • Unique on a host • VLAN ID • 802.1q, 802.1ad? • Traffic shaping • Security

  6. vSphere port group • VM port group • Connecting VMs to the switch • Common VLAN ID • VM can migrate only when on the same Layer 2 subnet • VMkernel port group • Connecting host to the switch • IP, VLAN ID • Using • Management • vMotion • Fault Tolerance • iSCSI, NFS

  7. vSphere virtual switch • Networking for host and VMs • Directs network traffic between virtual machines and links to external networks • Combines the bandwidth of multiple network adapters and balances traffic among them. It can also handle physical network interface card (NIC) failover • Models a physical Ethernet switch • A virtual machine’s NIC can connect to a port • Each uplink adapter uses one port

  8. vSphere virtual switch • Standard • Local for a single host • Distributed • Over all hosts in a datacenter • Only for Enterprise Plus license • Consistent network configuration for migrating VMs • Port mirroring, Netflow, Network I/O Control • Network statistics and policies migrate with VM • Third party development • Cisco Nexus 1000V

  9. vSphere virtual switch vSwitch vSwitch vSwitch Distributed Virtual Switch standard switches distributed switches

  10. vSphere virtual switch • Uplinks • Assign real host’s NIC • Teaming • Failover • Capacity • LACP, LAG • Network discovery protocol • CDP, LLCP • No uplink • Internal communication

  11. VLAN • Segmenting physical LAN • Isolating groups • Using VLAN • EST – external switch tagging • Port groups with VLAN ID=0 • VST – virtual switch tagging • Trunk port on physical switch • VGT – virtual guest tagging • Trunk port on physical switch • Tagging performed by the VM • Secondary VLAN IDs • VLAN ID • 0 – no tagging • 1-4094 – valid VLAN ID • 4095 – private ID, used for VGT
