This document discusses several new features in vSphere Distributed Switch version 6.0, including improved support for routed vMotion traffic using multiple TCP/IP stacks, enhanced vMotion capabilities between vCenters, and new capabilities for Network I/O Control version 3.0 to provide bandwidth reservations and guarantees for virtual machines and distributed port groups.

- 4. Migration VSS to VDS Mixing 1Gb and 10Gb Hosts Handling vMotion Saturation vSphere Replication Bandwidth Quality of Service Tagging Load Based Teaming vs Link Aggregation
- 5. 100% VDS Fueled Data Center • How to protect vCenter Server and other dependencies • Toss out the Standard vSwitch completely Using Multiple TCP/IP Stacks • Setup a supported Routed vMotion environment • Migrate workloads from one vCenter to another Granular Network Guarantees • Network I/O Control Version 3.0 • Setting guarantees on virtual machines and DPGs
- 6. The vSphere Distributed Switch 6.0
- 8. Network I/O Control (NIOC) Version 3.0 Multicast (IGMP) Snooping Multiple TCP/IP Stack for vMotion
- 9. • VMware no longer sells the Nexus 1000v • Nexus 1000v is supported in vSphere 6.0 Requires 5.2(1)SV3(1.4) or Later • Cisco Nexus 1000v AVS Mode = Not Supported
- 10. http://www.vmware.com/products/cisco-nexus-1000V
- 11. “The Nexus 1000v … is the market leading 3rd party virtual switch in the industry”
- 12. The vSphere Distributed Switch 6.0
- 13. VDS 4.0 We hardly knew thee
- 15. Beware!
- 16. VDS 5.0 VDS 5.1 VDS 5.5 VDS 5.5 + LACP VDS 6.0 VDS 6.0 + LACP VDS 5.1 VDS 5.5 VDS 5.5 + LACP VDS 6.0 VDS 6.0 + LACP VDS 5.5 VDS 5.5 + LACP VDS 6.0 VDS 6.0 + LACP VDS 5.5 + LACP VDS 6.0 + LACP VDS 6.0 VDS 6.0 + LACP VDS 6.0 + LACP
- 17. “Discover how easy it can be to begin using the vSphere Distributed Switch (VDS) for all workloads, even vCenter and other management dependencies”
- 19. Ephemeral Binding Per port group setting
- 20. Ephemeral Ports Still Available
- 21. Choosing a port binding type in ESX/ESXi http://kb.vmware.com/kb/1022312 Protecting a Distributed Switch with Ephemeral Binding http://wahlnetwork.com/2015/01/30/vds-ephemeral-binding/
- 22. “Gain valuable insight on how to best configure your VDS to take advantage of the new vMotion TCP/IP stack for routed traffic”
- 30. • Choose destination network when vMotioning VMs • Can go between vSS to vSS vSS to vDS vDS to vDS • Note that vDS to vSS is NOT supported vDS includes metadata that vSS doesn’t support • Does NOT change IP address
- 32. • vMotion VMs from one vCenter to another Must be in same SSO domain • Supports shared or shared nothing storage configurations • Even migrates things such as HA settings DRS settings Alarms Events
- 33. • Must be on Enterprise Plus licensing! • vCenter Servers must be in Enhanced Linked Mode • Make sure you have good time sync of the vCenters
- 34. • Can now vMotion across links up to *150ms* of latency! No more 10ms limit! • Keep in mind that this can affect VM application performance Do this in non-peak hours
- 35. “Learn how to leverage the new NIOC version 3 features found in the VDS 6.0 for building robust multi-tenant configurations”
- 36. • More guardrails = less fluidity in the data center • The best designs are simple • Are you solving a problem?
- 37. • Places VM’s network adapter on optimal NIC • Must be able to meet reservation • Still adheres to teaming policies Active, standby, and unused • Two control points Distributed Port Group (all VMs attached) Virtual Machine (per VM)
- 38. • Validation at VM power on Must meet minimum bandwidth to VM’s network adapter Reservation is less than the free quota in the pool • Changes are validated in real time Violations prevents change from applying
- 39. vSphere DRS DRS will migrate when … • Reservation exceeds host capacity • NIC fails vSphere HA HA considers the reservations when powering on a VM
- 44. Assign Reservation to the Virtual Machine System Class
- 45. Bandwidth reservation is based on network adapter quantity and speed Do the math! 0.5 Gbps per NIC x 6 NICs (2 per server) = 3.0 Gbps globally
- 46. Assign a reservation value (Mbps) to the Virtual Machine System Class
- 47. Associate port group(s) with the resource pool(s)
- 48. Bask in the amazement!
