Helping customers transform to a hybrid infrastructure
Improve 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

“Organizations should consider HPE for any data center network
solution, especially those looking for open and standards-based
solutions.”

Types of Fabrics
Layer 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. 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

11. 11#ATM16
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

12. 13#ATM16
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

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.

14. 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)

16. 17#ATM16
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

19. 20#ATM16
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”

IP Fabric
Example 9: Storage & Converged Fabric
• When storage connectivity is required, converged both FC/Ethernet or FCoE/IP with universal access
• Spilt out to separate IP/SAN fabrics from leaf/ToR switches:

21. 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?

• HPE has comprehensive fabric capabilities
• HPE offers standard based “open” fabric
• Final design depends on customer
requirements
• Typical products:
− Spine = 7900/ 12900
− Leaf = 5900/ 5930/ 7900 / 12900
