The “Virtual Data Centre” Approach
© 2012 Cisco and/or its affiliates. All rights reserved. Cisco Connect 12
Data Centre Row 1
What’s Wrong With That?
Data Centre Row 2
 Virtualization (vMotion, Live Migration, etc.) are
changing multiple aspects of the Data Centre design
 Where is the server now?
 Where is the access port?
 Where does the VLAN exist?
 Any VLAN Anywhere?
 How large do we need to scale Layer 2?
 Capacity planning requirements
 Policy boundaries (Security, QoS, acceleration, …)?
 What about programmability and automation ?

Policy Plane
The business glue of the network. Rules execution, decision making, Service
Manager and all the other components to make a productize service.
Services Plane
Overlay “Layer 7” application flow built on the foundation of the other layers.
Dependent on the other layers.
Management
Plane
The management plane is the logical path of all traffic related to the system
management of the platform.
Control Plane
It’s the brain of any networking platform and the technical glue of the network. The
control plane is where all routing, switching, other protocols and control information
are exchanged
Data Plane
The data plane receives, processes, and transmits network data between network
elements, and represents the bulk of network traffic that passes to and through the
gear.

 Port Extenders can be Cascaded
 Traffic from each “Extended Port” is segregated in an E-channel,

Looking forward: Full Unified Fabric
SAN Separation at the Access Switch
• LAN/SAN traffic share switches and links
• FabricPath enabled
• All Access switches are FCoE FCF switches
• VE_Ports to each neighbor Access switch
• Shared forwarding engine (FabricPath)
• Improved (N + 1) redundancy for LAN & SAN
• Sharing links increases flexibility and scalability
• Distinct SAN ‘A’ & ‘B’ for zoning and multipath
• With FC-BB-6 on the future:
• Access switches for server connectivity to behave as FDF
• FDF to FCF transparent failover
• VA_Ports to each neighbor FCF switch

Before we get started: “SDN-related” Definitions
What Is Software Defined Network (SDN)?
“…Software Defined Networking (SDN) is a network
design concept in which the network control plane is
centrally accessible through an API to applications
wanting to better use the network…
Source: wikipidea
What is OpenStack?
Opensource software for building public
and private Clouds; includes Compute (Nova),
Networking (Quantum) and Storage (Swift)
services.
Source: www.openstack.org
What is Overlay Network?
Overlay network is created on existing network
infrastructure (physical and/or virtual) using a network
protocol. Examples of overlay network protocol are:
MPLS, GRE, IPSEC, LISP, OTV and VXLAN
What Is OpenFlow?
“…open standard that enables researchers
to run experimental protocols in campus networks.
Provides standard hook for researchers to run
experiments, without exposing internal working of
vendor devices…”

Opensource software for building public and private Clouds; includes Compute (Nova), Networking (Quantum) and Storage (Swift) services. Source: www.openstack.org What is Overlay Network? Overlay network is created on existing network infrastructure (physical and/or virtual) using a network protocol. Examples of overlay network protocol are: MPLS, GRE, IPSEC, LISP, OTV and VXLAN What Is OpenFlow? “…open standard that enables researchers to run experimental protocols in campus networks.
