Why Do We Need Another Server:

Management

Chassis Management•New management layer

Benefits•Consistency in chassis

•Shared chassis infrastructure

monitoring

Weakness•Additional mgmt overhead

•Additional cost overhead

•Need chassis aggregation management

Nexus 7000 Module Overview

Crossbar Switch Fabric Module

• Each fabric module provides 46Gbps per I/O module slot

• Initially shipping I/O modules do not leverage full fabric bandwidth

–Maximum 80G per slot with 10G module (160 full duplex)

–Future modules leverage additional available fabric bandwidth

• Access to fabric controlled using QoS-aware central arbitration with VOQ

What is FET-10G

• FET is an optical transceiver that provides a highly cost-effective solution for connecting Nexus 2000 to Nexus 5000 (N2K to N5K only).

• FET-10G must be connected to another FET-10G

• Supported on N2248TP / N2232PP uplinks and N5010P / N5020P 10G fabric links

• MMF: 25M (OM2), 100M (OM3)

• Not compatible with SR optics

New NX-OS 4.2(1)N1 Software Features

• Local Port Channels on FEX-10G and FEX-100/1000

• In-Service Software Upgrade (ISSU)

• F-Port Trunking and Channeling

• VTP Transparent Mode Support

Additional features:• ACLs for SNMP Communities• Increase to 8K Logical Ports• LLDP on FEX Ports• CDP on FEX Ports• AAA Command Authorization

Both protocols have- different Ethertypes

- different frame formats

Unified Fabric with FCoEProtocol Organization

FCoE Protocol

• is the data plane protocol

• is a Fiber Channel frame encapsulated within an Ethernet frame

• carries most of the FC frames and all the SCSI traffic

FIP (FCoE Initialization Protocol)

• the control plane protocol

• discovers the FCoE capable devices connected to an Ethernet cloud

• Responsible for the FC Login and Logout processes

FCoE Benefits

FC over Ethernet (FCoE)

• Mapping of FC frames

over Ethernet

• Enables FC to run

on a lossless Data Center

Ethernet network

• Wire Server Once

• Fewer cables and adapters

• Software Provisioning of I/O

• Interoperates with

existing SANs

• No gateway—stateless
