Introduction
The Cisco NX-OS software is a data center-class operating system built with modularity, resiliency, and serviceability at its foundation. Based on the industry-proven Cisco MDS 9000 SAN-OS software, Cisco NX-OS helps ensure continuous availability and sets the standard for mission-critical data center environments. The highly modular design of Cisco NX-OS makes zero-effect operations a reality and enables exceptional operational flexibility. Cisco NX-OS software offers the following benefits:
•Cisco NX-OS runs on all Cisco data center switch platforms: Cisco Nexus 7000, 5000, 4000, 2000, and 1000V Series.
•Cisco NX-OS interoperates with Cisco products running any variant of Cisco IOS software and also with any networking operating system (OS) that conforms to common networking standards.
•Cisco NX-OS modular processes are triggered on demand, each in a separate protected memory space. Processes are started and system resources are allocated only when a feature is enabled. The modular processes are governed by a real-time preemptive scheduler that helps ensure timely processing of critical functions.
•Cisco NX-OS provides a programmatic XML interface based on the NETCONF industry standard. The Cisco NX-OS XML interface provides a consistent API for devices. Cisco NX-OS also provides support for Simple Network Management Protocol (SNMP) Versions 1, 2, and 3 MIBs.
•Cisco NX-OS enables administrators to limit access to switch operations by assigning roles to users. Administrators can customize access and restrict it to the users who require it.
Cisco Nexus 3000 Series Switches
The Cisco Nexus 3064PQ switch is a high-performance, high-density, ultra-low-latency Ethernet switch that is part of the new Cisco Nexus 3000 Series Switches. This compact one-rack-unit (1 RU) form factor 1- and 10-Gigabit Ethernet switch provides line-rate Layer 2 and 3 switching. The switch runs the industry-leading Cisco NX-OS Software operating system. The Cisco Nexus 3064PQ is well suited for financial co-location deployments that require support for robust unicast and multicast routing protocol features at ultra-low latencies.
For information about the new Cisco Nexus 3064PQ switch, see the "New Hardware Features" section. For information about the Cisco Nexus 3000 Series, see the Cisco Nexus 3000 Series Hardware Installation Guide.

The Cisco Nexus 3064PQ delivers ultra-low nominal latency that enables you to implement high-performance infrastructures for high-frequency trading workloads.
•Wire-rate Layer 2 and 3 switching on all 64 10-Gigabit Ethernet ports
Layer 2 and 3 switching of up to 1.2 terabits per second (Tbps) and more than 950 million packets per second (mpps) in a compact 1 RU form-factor switch
•Purpose-built on Cisco NX-OS operating system with comprehensive, proven innovations
–Modular OS built for resiliency
–Full Layer 3 routing protocol suites, including Border Gateway Protocol (BGP), Open Shortest path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Routing Information Protocol Version 2 (RIPv2)
–Rich feature set including IP multicast, High Availability, Security, and IP services.
This section describes the following new hardware:
Cisco Nexus 3064PQ switch
The Cisco Nexus 3064PQ switch includes the following features:
•1 RU fixed form-factor 1-, 10-Gigabit Ethernet switch offering a throughput of up to 1.28 TBps
•64 10-Gigabit Ethernet ports (48 SFP+ and 4 QSFP+)
•48 fixed 1/10 Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) ports
•4 fixed Quad SFP+ (QSFP+) ports (each QSFP+ port is 4 x 10-Gigabit Ethernet capable)
•Locator LED
•Dual-redundant power supplies
•Hot-swappable fan tray with redundant fans that can function with up to one failed fan
•One 10/100/1000 management ports

•One USB port
•1.28-Tbps switching capacity
•Forwarding rate of 950 mpps
•Line-rate traffic throughput (both Layer 2 and 3) on all ports
•Configurable maximum transmission units (MTUs) of up to 9216 bytes (jumbo frames)
Note The Cisco Nexus 3064PQ switch includes two management ports; however, Cisco NX-OS Release 5.0(3)U1(1a) provides support for one management port.
Transceiver and Cabling
The Cisco Nexus 3064PQ switch supports 1- and 10-Gigabit Ethernet connectivity options using SFP+ transceivers in the first 48 ports, and 4 x 10-Gigabit Ethernet connectivity is achieved using QSFP+ transceivers in the last 4 ports.
QSFP+ technology allows smooth transition from 10- to 40-Gigabit Ethernet infrastructure in data centers. The Cisco Nexus 3064PQ switch supports connectivity over copper and fiber cables, providing excellent physical-layer flexibility. For low-cost cabling, copper-based 40-Gbps Twinax cables can be used.
Connectivity can be established from the QSFP ports to an upstream 10-Gigabit Ethernet switch using a cable that has a QSFP transceiver on one end and four SFP+ transceivers on the other end Similar capability can be achieved using optical transceivers by procuring third-party optical branching cables.
