Introduction
Series Overview
Fixed-Configuration Switches
Cisco Nexus 5000 Series
The Cisco Nexus 5000 Series
Switches help you transform the data
center with innovative, standards-
based, multilayer, multiprotocol, and
multipurpose Ethernet-based fabric.
Now with the Unified Ports functionality
you can help enable any transport over
Ethernet, including Layer 2 and Layer
3 traffic, and storage traffic, all on one
common data center-class platform.
• Based on the Cisco ® NX-OS
operating system, that is resilient,
efficient, virtualized and extensible
• High performance, low latency
system with up to 1.92 Tbps
switching fabric and 1428 Mpps
forwarding rate
• Front-to-back cooling supports
efficient data center hot- and
cold-aisle designs
• Unified ports provides flexibility in
choosing SAN and LAN port options
consistent with the virtualized data
center and offer a migration path
to FCoE
• LAN and SAN Convergence ready
through FCoE-based unified fabric
and Fibre Channel support in a
lossless Ethernet service platform.
Energy efficiency achieved with the
convergence of the networks
• Virtualization-aware networking
through virtualization optimized
services and mobility by mapping
virtual machines to network profiles
• Supports the extension of the fabric
extender technology into the servers
and virtual machines via Adapter
FEX and VM-FEX technologies.
Nexus 5000 Series Switches acts
as the single point of network
management for these servers and
virtual machines
• Pair with Nexus 5000 for up to 24
fabric extenders per Cisco Nexus

Cisco Nexus 3000 Series
Cisco Nexus 3064 Switch is a high
performance, high density, sub-micro-
second latency ethernet switch, which
is part of the brand new Cisco Nexus
3000 Series Switches. This compact
1RU form factor 10GbE switch provides
wire-rate L2 and L3 switching and
future-proofs networks with 40GbE
standards-based technologies while
also being backward compatible with
1GbE. Cisco Nexus 3064 is ideal for
financial co-location deployments
requiring support for advanced unicast
and multicast routing protocol features
at ultra-low latency.Cisco Nexus 3000
Series Switches extends the compre-
hensive proven innovations of Cisco
Data Center Business Advantage into
the HFT market too. The switch does
so by delivering functionalities such as
ultra-low latency and wire-rate L2/L3
switching on data center class NX-OS
operating system.
The key challenges addressed by the
Cisco Nexus 3000 series include:
• Increased application sensitivity to
network latency
• Increasing bandwidth requirements
due to increasing application
workloads
• Need for supporting advanced
routing protocols with resiliency
• Need to measure network latency
between servers
Key highlights of Cisco Nexus 3000
Series Switches:
• Ultra Low Latency
- Cisco Nexus 3000 Series Switches
delivers ultra-low latency that
translates to faster data transactions
thereby resulting in increased
revenue for the financial companies.
• Wire-rate 10 Gigabit Ethernet
Switching on all 64 10GbE ports
- Layer 2/3 switching up to 1.2Tbps,
over 950Mpps (Million Packets per
second) in a compact 1RU form
factor switch.
- Future-proof with 40GbE
standards-based support
• Purpose-built on NX-OS operating
system with comprehensive, proven
innovations
- Modular OS built from the ground
up for resiliency
- Full L3 routing protocol suites
including BGP, OSPF, EIGRP, RIPv2
- Integration with Cisco DCNM and
XML management tools
- Support for Precision Time Protocol
(IEEE-1588) to synchronize system
clocks with nanosecond accuracy
Cisco Catalyst 4500-X Series
The Cisco Catalyst ® 4500-X Series
offers best-in-class Layer 2 and
Layer 3 services in a small form
factor for space-constrained LAN
aggregation in campus and branch-
office deployments. The switch
simplifies aggregation deployments
using the new Cisco IOS ® XE Software
Operating System with several
important innovations such as virtual-
ization, application visibility, and hosted
applications such as Wireshark.
• Layer 2–4 switching and intelligent
services with 250-Mpps IPv4 and
125-Mpps IPv6
• Rich IP Multicast, quality of service
(QoS), and security
• Flexible NetFlow and Wireshark
• Simplified virtualization and
application monitoring
• Wire-rate performance delivering
800 Gbps
• Configurations from sixteen to forty
10 Gigabit Ethernet ports
• Every port configurable in 1 or 10
Gigabit Ethernet mode
• Resilient with dual hot-swappable
internal AC or DC power supplies
• Hot-swappable fans with N + 1
redundancy
