Helping customers transform to a hybrid infrastructureImprove the user experience with accelerated the delivery of apps & services

• Increase availability to gracefully support business growth and unpredictable

• Reduce time to service to enhance business agility

• Enhance customer choice for freedom to build networks that suite business requirements

• Lower total cost of ownership to gain competitive edge in the market

Types of FabricsLayer 2 or Layer 3 and more

Layer 2 STP and STP variants TRILL / SPB Proprietary protocols (IRF,

Fabricpath, VCS, MLAG) VXLAN (something in

between)

Layer 3 OSPF / BGP Better scalability Predictable path Easy to troubleshoot

9#ATM16

STP Variants

– STP– rPVST+, RSTP, MSTP

– Load-share across the available links on a per VLAN basis

– Root Bridge (RB) election - Who remembers this?– Lowest bridge ID (priority)– If bridge IDs are all the same lowest MAC address– HPE Comware devices reverse this (highest priority is elected RB)

– In PVST the lowest priority will become the root bridge for a VLAN

Example 1: Traditional IRF L2 Fabric

• Centralized IRF L2/L3 core switches

• IRF L2 access switches

• Loop free L2 fabric

• STP should still be enabled to prevent any possible loops in future

Example 2: L2 Fabric with control plane (SPB/TRILL)

• SPB/TRILL removes STP while still providing a loop free L2 network for east/west traffic• Distributed control plane (No single point of failure)• Architecture Neutral (leaf to leaf or spine leaf)• Lack of control plane interoperability L3 Gateway

Fabric

14#ATM16

What is a fabric?– Interconnected network nodes that look like a “fabric” when viewed collectively from a distance

– Spine leaf/ CLOS /Two-Tier /Ethernet Fabric /Network Fabric are interchangeable and commonly used terms

– For most it’s a scalable, high performing, resilient network architecture.

15#ATM16

Example 3: CLOS Fabric• CLOS (physical) network architecture provide edge/core multi-tier design• Each leaf switch is connected to all spine switches• Customers may choose to deploy a 2 spine fabric (2 x 40G uplinks) and expand to 4+ spines (4 x

40G uplinks or more) when they require additional bandwidth • Protocol independent (STP/TRILL/SPB/L3) over the physical fabric

Example 4: L3 Fabric

• Removal of STP• Usage of standards based routing protocol• Shortest path routing• Provides Equal Cost Multi Pathing (ECMP)• Traffic engineering

Example 5: Network Virtualization Enabled Fabric• Network Virtualization enabled fabric provides virtual to physical networking bridging capabilities• Underlay network fabric can be deployed either as L2 / L3• Most devices do not need to be VXLAN Tunnel End Points (VTEP) or VXLAN capable (e.g. SPINEs

only need to route traffic between VTEPs) • L3 fabric recommended if network virtualization software supports different subnets between VTEPs• Hardware VTEPs used to bridge between virtual and physical networks

Example 6: L2 over L3 VXLAN overlay Fabric

• Loop free L2 fabric without STP or network virtualization controllers

• VXLAN overlay tunnels provides link load sharing across the physical fabric

• High performance multicast forwarding in the underlay (compared to multicast forwarding using the overlay)

Example 7: Multiple Fabrics• Network fabrics can be deployed as different availability zones to limit failure domains• L2 network connectivity between VMs/Servers are provided within an availability zone• L3 used between different availability zones • Border leaf switches used to connect out of an availability zone

Example 8: Inter Data Center Fabric Connectivity• VXLAN and HPE EVI technologies can be combined for active/active inter-DC L2 DCI over L3

WAN• EVI provides additional benefits such as:

− Active/Active VRRP default gateways for VMs− STP failure domain local to each DC− Improves WAN utilization by dropping unknown frames and providing ARP suppression− Optimized Server/Client Traffic Paths

• VXLAN based DCI must avoid full networking “interconnect”

22#ATM16

Which Fabric deployment to choose?• It depends on customer requirements!

• L2 between access/core layer in the DC: Used in the DC mainly because it L2 connectivity is required by the applications across racks, L2 loops are typically more difficult to troubleshoot compared to L3

• Traditional IRF L2 fabric works and is mature

• L3 between access/core layer in the DC: Main benefit is STP is no longer required to prevent loops, L3 routing protocol is used, easier to troubleshoot for network OPs

• Decision for L2/L3 between access/core layer in the DC really depends on application network requirements.

• VXLAN over L3 fabric in the DC provides L3 fabric benefits while providing L2 network connectivity for applications

• Is there a requirement to support storage traffic FC/FCoE and/or iSCSI?
