Evolution of the Data Center
Once, Campus-class was good enough
Traditional networks are
designed for north/south
traffic – ToR Switches
interconnected by the
Core or Aggregation…
Rack 1

• 20-30 microseconds
for every hop
• Modern applications
have an average of
8 transactions

Evolution of the Data Center
Traffic patterns were traditional
• What this meant:
– Application traffic
traverses multiple
Switch hops – Access
/ Core / ToR / Core /
Access
– Uplinks were more
important than InterRack capacity
Traditionally:
The North-South
to East-West
ratio has been
80:20
Top-of-Rack
Switches
Racked Servers

What’s the approach of the “Big 2”..?
• Cisco’s Vblock “marketecture” was the first salvo
• HP responded by purchasing 3COM/Huawei assets
• Both offered “end-to-end” architectures
• Server/Storage/ToR/EoR/Core
• The explosion of Virtual Machines has changed
everything
• What’s next..?
• Collapsed 2-Tier architecture and “Fabric”
• Why..?
• Better L2 scale, overcoming STP & VLAN limits
• Scalable support for L3 & VRFs

HP’s 2-Tier Network Design
An Improvement..?
Switch Clustering has done this for the last 12 years..!
2-Layer may reduce cost, but all traffic still goes to Core

Avaya Fabric DToR
Winning on Throughput & Latency
• Avaya Fabric Connect provides more throughput than
competing solutions.
• Competitors offer 128Gbps stacking or 4x40GE
(160Gbps) links.
• FI Stacking up to 20Tbs and Fabric Connect Mesh
supports up to 262.5Tbs.
• Avaya Fabric Connect provides lower latency than
competitors.
• “Ultra Low Latency” competitor provides
7.9uS latency (ToR-Distribution-ToR)
• Fabric Connect Stacking provides latency of 2.1uS –
5.3uS (4 hop maximum in stack of 8)

Avaya Fabric DToR
Winning on Price
•
•
Avaya Fabric DToR provides cost effective means to interconnect ToRs vs
typical Fat Tree designs of 4 - 20x lower cost.
Typical Fabric Connect deployment costs with 640Gbps for $6,780
•
•
•
4 x 3m Fabric Connect cables (640Gbps) per VSP 7000 with MSRP $6,780.
Fabric Connect cables range from $995 for 0.46m to $8,995 for 100m.
Competing designs with 160Gbp from $27,150 - $142,150
•
•
Competing ToR limited to 160Gbps due to 4 x 40GE ports per ToR.
Due to placement of ToR to Core or Distribution switches require longer cable
runs
• 8 x 40GBASE-SR4 @ $1,100ea + 8 x Fibre @ $250ea = $12,150
•
Require 8 modular ports at costs from $1,875 ea to $ 16,250ea
•
•
•
•
Arista (standalone) $1,875/port
Cisco Nexus 7000: $9,940/port
Juniper (standalone) $2,306/port, QFX3008 $7,226 - $16,250/port

VSP 7000 Fabric DToR
Fabric Interconnect Stacking
•
•
Fabric Stack Mode, in which up to 8 units create a DToR (distributed Top
of Rack) delivering up to 5Tbps using two Fabric Connect cables in
parallel between each switch.
For Fabric DToR Stack operation, the stack operates in the same manner
as other Avaya stackable products and features many of the associated
benefits of Stacking
•
•
•
•
•
Single IP Address Management for Fabric Connect Stack.
Hot Swap Unit replacement with AUR, DAUR, AAUR.
Hot Unit Insertion with NUQC.
Distributed uplinks with DMLT and LAGs.
For Fabric Connect Stack operation each pair of the Up/Down ports
should be thought of as a single connection between each switch.
•
You will need 2 Fabric DToR Cables between each switch to form full adjacency
and the top port on the Up must be connected to the top Down port on an
adjacent switch and similarly for the bottom connector

While application scale

Server virtualization brings scale
and efficiency to applications. VMs
become essentially “jailed” and
network flexibility is reduced.
VM Mobility is seriously limited. What is the alternative…?

•
•
Avaya’s FI Mesh delivers unmatched scalability
to address low latency East-West requirements in
the Data Centre
Switches in the Mesh are managed through COM
& VPS providing unified provisioning.
Fabric Connect Mesh is scalable from 4 to 480
switches per region.
• Providing low latency fabric.
• Fabric is scalable up to 262.5Tbps.
• Extensible up to 15,360 10GE ports.
• Designed to enable either 24/32/48/56/64
10GE ports per rack.
Fabric DToR ports interconnect each VSP7000:
• Can use mix of different Fabric DToR cable
lengths.
• Optimum performance will be achieved
when the same colour designated ports are
connected to one another.

Avaya Fabric Connect DToR Mesh
•
•
•
Extending the FI Mesh of the
VSP 7000 can be easily
achieved through adding VSP
9000 (or ERS 8800).
VSP 9000 are connected to the
VSP 7000 via high speed
connections to handle traditional
North-South traffic.
VSP 9000 provide advanced
services to the Fabric Connect
Mesh.
