BrownBag - vCloud Networking — Presentation Transcript

vCloud NetworkingUnderstanding the Design www.kendrickcoleman.com

The Basic Concepts• External Networks• Organization Networks• vApp Networks• Network Pools – Port-group – VLAN – vCD-NI

External Networks• Identified by a vSphere Portgroup• Must be created outside of vCD

Organization Networks• Organizations describe a tenant• Networks that belong to an Organization• 3 Types of Org Network Connections• Internal and External• Created by the cloud admin

vApp Networks• Networks available to a single vApp• Ability to Fence• vApp Networks connect to Organization’s Internals or External Networks

Network Pools• Giving the users control of L2• Creating the multi-tenant infrastructure• Declaring what L2 networks are available for consumption• 3 Different kinds of Network pools

Port-Group Backed• Pre-provisioned port-groups• Non-automated• vSphere Standard Switches• Currently Nexus 1000v, until 1.5 GA release

VLAN Backed• Automated provisioning• Specify a range of VLANs• Network re-use

vCD-NI Backed• vCloud Director Network Isolation• Mac-in-mac encapsulation• Breaking the 4094 VLAN barrier

More Resources• vCloud Director Networking for Dummies – http://it20.info/2010/09/vcloud-director- networking-for-dummies/• Mike D’s 2010 & 2011 VMworld Presentations – vCloud Networking Finally Explained

The Physical Design• 1Gb vs 10Gb• X NICs vs Y NICs• Service Offering• The Pod Approach

External Design• How many external networks are needed?

Enterprise

Service Provider

Enterprise or Service Provider

External Network Creation• Create portgroup before vCD external creation• Use Ephemeral binding• Assign a VLAN• Layer 2 or Layer 3• IP Address Range with Gateway• DNS• Load Balancing & Failover

External Network Creation

Network Pool Design• Which type of network pool?• Port-group vs VLAN vs vCD-NI

vCD-NI• VMware’s proprietary protocol• How many?• VLAN• L2 or L3?

vCD-NI and MTU• MTU > 1600 – Network Equipment – vNetwork Distributed Switch – vCloud

vCD-NI and MTU• MTU > 1600 – vCloud

vCD-NI Allocations• Quotas per organization

Different Organization Networks• Multiple Org vDCs can be in one Organization• Multiple Org vDCs can share Org Networks in one Organization

Internal & External Routed

Internal and External Direct

Scalability
