Q & A
© 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 25Cisco Expo 2008
I/O Module Bandwidth Capacity
Initially shipping I/O module bandwidth: 80Gbps per slotAssumes 8 * 10G ports in dedicated mode per module
In Nexus 7000 10-slot chassis:(80Gbps/slot) * (8 payload slots) = 640Gbps
(640Gbps) * (2 for full duplex operation) = 1280Gbps = 1.2Tbps system bandwidth
1.2 Terabits per second initial system bandwidth
© 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 26Cisco Expo 2008
Fabric Bandwidth Capacity
Initially shipping fabric bandwidth: 230Gbps per payload slot, 115Gbps per supervisor slot
Initially shipping modules cannot fully leverage fabric bandwidthAssumes future modules that can leverage full bandwidth
In Nexus 7000 10-slot chassis:(230Gbps/slot) * (8 payload slots) = 1840Gbps(115Gbps/slot) * (2 supervisor slots) = 230Gbps(1840 + 230 = 2070Gbps) * (2 for full duplex operation) = 4140Gbps = 4.1Tbps system bandwidth
4.1 Terabits per second fabric bandwidth capacity
© 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 27Cisco Expo 2008
Future Vision for Platform Series
Future goal to double fabric bandwidth500+Gbps bandwidth per slot
Requires future fabric module
10 slot chassis will scale to 9+Tbps system bandwidth
18 slot chassis will scale to 15+Tbps system bandwidth
15+ Terabits per second platform bandwidth capacity
© 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 28Cisco Expo 2008
Fabric Module
Provides 46Gbps per I/O module slot
Also provides 23G per supervisor slot
Up to 230Gbps per slot with 5 fabric modules
Initially shipping I/O modules do not leverage full fabric bandwidth
Load-sharing across all fabric modules in chassis

46Gbps92Gbps138Gbps184Gbps230Gbps
Fabric Capacity and RedundancyPer-slot bandwidth capacity increases with each fabric module
1G module requires 2 fabrics for N+1 redundancy
10G module requires 3 fabrics for N+1 redundancy
4th and 5th fabric modules provide additional level of redundancy
Future modules will leverage additional fabric bandwidth
Fabric failure results in reduction of overall system bandwidth

(send traffic into fabric based on destination)

Centralized Fabric Arbitration
Access to fabric bandwidth on ingress module controlled by central arbiter on supervisor
In other words, access to the VOQ for the destination across the fabric
Arbitration works on credit request/grant basisModules communicate egress fabric buffer availability to central arbiterModules request credits from supervisor to place packets in VOQ for transmission to destination over fabricSupervisor grants credits based on egress fabric buffer availability for that destination
Arbiter discriminates among four classes of servicePriority traffic takes precedence over best-effort traffic across fabric

Ensures fair access to bandwidth for multiple ingress ports transmitting to one egress portPrevents congested egress ports from blocking ingress traffic destined to other portsPriority traffic takes precedence over best-effort traffic across fabricEngineered to support Unified I/O
Can provide no-drop service across fabric for future FCoE interfaces

NX-OSSoftwareArchitecture
‘Next-generation’ operating system that brings 3 fundamental technologies into a single platform:– Layer-2 classical (now) and unified I/O switching (future)– Layer-3 multi-protocol routing (now)– Storage protocols and SAN switching (future)
“100% features for 80% of the customers”– NX-OS is not all things to all people– But is state of the art for targeted environments
Design Philosophy– Invest in sophisticated software infrastructure so that multiple features can leverage it– Dealing with software complexity that is growing all the time– Focus on Serviceability– Provide comprehensive management that extends well beyond CLI using a Wizard-based GUI– Modularity is paramount

NX-OS LicensingSimple, Flexible Licensing Model
There are three levels of enforced licensing: Base, Enterprise Services, and Advanced Services
Grace periods facilitate feature testing and trials without buying a license (for example, 120 days), with some restrictions. The Cisco Trusted Security does not have a grace period because of export restrictions on strong cryptography
