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 6

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) 12

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 HP (no offering) 13 Avaya Fabric Connect – the new DNA for your Data Centre Network

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 14
