4 1. Introduction This system select guide describes CommScope s pre-terminated structured cabling solutions for the most common networking architectures in data centers using the data center switches. It covers the structured cabling within and between switching layers (core, aggregation and access resp. spine/leaf) and highlights several cabling options and migration paths for ethernet applications from 1 Gb/s to 100 Gb/s. Due to the participation in the Cisco Solution Partner Program, CommScope was able to define a powerful but small selection of cabling model types, both copper and fiber optic, allowing an easy selection of structured cabling types for the most common networking variations with switches. This booklet uses 2 structured cabling types from CommScope: The MRJ21 XG solution from CommScope is a preterminated copper cabling system designed to deliver 10 GbE throughout all architectures where copper cabling is required. The 24 Fiber MPOptimate system comprises a portfolio of cassettes, trunks, patch-cords and mounting hardware. This system enables data center managers to easily migrate their infrastructure to support the 10, 40 and 100 Gb/s data speeds required to support the next generation of servers, storage and switching platforms in the data center. For simplification reasons, the cabling model types for fiber optic use the OM4 fiber in the bill of material for each type. All fiber optic products are available with OM3 fiber as well. Covering the data center backbone (core & aggregation) in the main and zone distribution as well as all the networking & cabling variants in the equipment area, the guide helps data center designers and operators as well as data center networking specialist to select quick & easy the structured cabling type needed for any specific environment. 4

17 4.4. Architectures with 7xxx in aggregation Nexus 5xxx/2xxx in Access xxx switches The 5600 platform is designed for top-of-rack (ToR) and middle-of-row (MoR) deployment in data centers that support enterprise applications, service provider hosting, and cloud computing environments. The Cisco 5600 platform switches come in these configurations: 5672UP Switch: Figure 16: 5672UP switch port view (rear) (source: Cisco) The 5672UP is a 1RU 10 and 40 Gigabit Ethernet switch offering wire-speed performance for up to seventy-two 10 Gigabit Ethernet ports (using quad small form-factor pluggable [QSFP] breakout cables). 5672UP switches are layer 2 and 3 non-blocking 10 and 40 Gigabit Ethernet and FCoE-capable switches with up to 1.44 terabits per second (Tbps) of internal bandwidth. The 5672UP offers 48 fixed 1 Gigabit and 10 Gigabit Ethernet ports of which 16 ports can be unified ports (UP). The 16 unified ports provide 8/4/2-Gbps Fiber Channel as well as 10/40 Gigabit Ethernet and FCoE connectivity options. The 5672UP also offers 6 ports of 40 Gbps using QSFP transceivers for Ethernet and FCoE support. The 5672UP has three fan modules and two power supplies. The 5672UP is VXLAN ready, with VXLAN support in bridging and routing modes, on all ports at line rate, enabling the migration of virtual machines between servers across layer 3 networks P Switch: The 56128P is a 2RU switch that supports 2.56 Tbps of bandwidth across 48 fixed 1 Gigabit and 10 Gigabit Ethernet SFP+ ports, and four 40-Gbps QSFP+ ports. The 56128P offers two expansion slots to support 24 ports of 10 Gigabit Ethernet and FCoE or 8/4/2-Gbps Fiber Channel and two ports of 40 Gigabit Ethernet using QSFP optics. The 56128P also offers two slots for a generic expansion modules (GEM). The GEM for the 56128P provides 24 ports 10G Ethernet/FCoE or 2/4/8G Fiber Channel and 2 ports 40 Gigabit QSFP+ Ethernet/FCoE ports. The expansion module supports native 40 Gigabit Ethernet on the QSFP+ ports. The expansion module is supported on the 56128P chassis only and can be populated in either of the two expansion slots. Figure 17: 56128P Port View (rear) (source: Cisco) Figure 18: Generic expansion module for 5672UP (source: Cisco) Note: For simplification reasons, this chapter uses the 56xx only to demonstrate the access layer configurations. In case of usage of the 55xx, the same structured cabling types apply. 17

18 xxx Fabric Extenders The 2000 series fabric extenders comprise a category of data center products designed to simplify data center access architecture and operations. The 2000 series uses the Cisco fabric extender architecture to provide a highly scalable unified server-access platform across a range of 100 Megabit Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, unified fabric, copper and fiber connectivity, rack, and blade server environments. The platform is ideal to support today s traditional Gigabit Ethernet while allowing transparent migration to 10 Gigabit Ethernet, virtual machine-aware unified fabric technologies. The 2000 series fabric extenders behave as remote line cards for a parent switch. The fabric extenders are essentially extensions of the parent switch fabric, with the fabric extenders and the parent switch together forming a distributed modular system. This architecture enables physical topologies with the flexibility and benefits of both top-of-rack (ToR) and end-of-row (EoR) deployments The 2000 series is built for nonstop operation, with redundant hot-swappable power supplies and a hot-swappable fan tray with redundant fans. Its compact 1-rack-unit (1RU) form factor takes up relatively little space, making it easy to incorporate into rack designs. The fabric extenders are available in several models to provide speed, connectivity, and port-density options. Figure 19 (source: Cisco): 2000 series fabric extenders from bottom right to top left: 2224TP GE, 2248TP GE, 2248TP-E GE, 2232TM 10GE, 2232TM-E 10GE, 2232PP 10GE, and 2248PQ 10GE; Cost-Effective fabric extender transceivers for 2000 series and parent switch interconnect are in front of the fabric extenders The following table shows the specifications of the different fabric extender models: Description 2148T Specification 48t 1000BASE-T host interfaces and 4 10 Gigabit Ethernet fabric interfaces (enhanced small form-factor pluggable [SFP+]) 2224TP /1000BASE-T host interfaces and 2 10 Gigabit Ethernet fabric interfaces (SFP+) 2248TP /1000BASE-T host interfaces and 4 10 Gigabit Ethernet fabric interfaces (SFP+) 2248TP-E /1000BASE-T host interfaces and 4 10 Gigabit Ethernet fabric interfaces (SFP+) 2232PP 2248PQ 2232TM 32 1/10 Gigabit Ethernet and Fiber Channel over Ethernet (FCoE) host interfaces (SFP+) and 8 10 Gigabit Ethernet and FCoE fabric interfaces (SFP+) 48 1/10 Gigabit Ethernet and FCoE host interfaces (SFP+) and 4 QSFP+ Gigabit Ethernet and FCoE fabric interfaces (QSFP+) 32 1/10GBASE-T host interfaces and modular uplinks (8 10 Gigabit Ethernet fabric interfaces [SFP+]) 2232TM-E 32 1/10GBASE-T host interfaces and uplink module (8 10 Gigabit Ethernet fabric interfaces [SFP+]), FCoE support up to 30m with category 6 A /7 cables Table 4: Fabric extender specifications (source: Cisco) 18

The 9300 platform is composed of fixed-port switches designed for top-of-rack (ToR) and middle-of-row (MoR) deployment in data centers that support enterprise applications, service provider hosting, and cloud computing environments series switches are layer 2 and 3 nonblocking 10 and 40 Gigabit Ethernet and Fiber Channel over Ethernet (FCoE)-capable switches with up to 1.28 terabits per second (Tbps) of internal bandwidth. The 9396PX switch is a 2-rack-unit (2RU) switch that supports 960 Gbps of bandwidth across 48 fixed 10-Gbps SFP+ ports and 12 fixed 40-Gbps QSFP+ ports. The 40-Gbps ports are provided on an uplink module that can be serviced and replaced by the user. Figure 28: Cisco 3-layer switching architecture with Nexus 9xxx (source: Cisco) The 9396TX switch is a 2RU switch that supports 960 Gbps of bandwidth across 48 fixed 1/10GBASE-T ports and 12 fixed 40-Gbps QSFP+ ports. The 40-Gbps ports are provided on an uplink module that can be serviced and replaced by the user. Figure 29: Cisco 3-layer switching architecture with Nexus 9xxx (source: Cisco) The 93128TX switch is a 3RU switch that supports 1.28 Tbps across 96 fixed 1/10GBASE-T ports and 8 fixed 40-Gbps QSFP ports. The 40-Gbps ports are provided on an uplink module that can be serviced and replaced by the user. The uplink module is the same for both switches. If used with the 93128TX 8 out of the 12 40Gbps QSFP+ ports are available. Figure 30: Cisco 3-layer switching architecture with Nexus 9xxx (source: Cisco) With the 9000 series, organizations can quickly and easily upgrade existing data centers through advanced optics that enable the use of existing 10 Gigabit Ethernet fiber (a pair of multimode fiber strands) to carry 40 Gigabit Ethernet to the aggregation layer or to the spine (in a leaf-andspine configuration). Additionally, the series can be deployed in MoR or end-of-row (EoR) configurations to meet the 10 Gigabit Ethernet connectivity requirements of multiple racks or pods. Cisco provides two modes of operation for the 9000 series. Organizations can use Cisco NX-OS Software to deploy the 9000 series in standard switch environments. Organizations also can use the ACI-ready hardware infrastructure to take full advantage of an automated, policy-based, systems management approach. 23

29 5. Fabric (Spine-Leaf) Architecture with 6xxx series switches x switches The 6004X is the latest switch in the 6000 series. It extends the industry-leading innovation and versatility of the 6000 series data center switches and runs the same industry-leading Cisco NX-OS Software operating system. The 6004X is versatile. Choose either front-to-back or back-to-front airflow options to suit traditional data center implementation or large-scale cloud deployments. And with 10 Gigabit Ethernet, 40 Gigabit Ethernet, and FCoE connectivity options, you can build a scalable Cisco Unified fabric across a range of physical and virtual server environments. An extensible architecture also makes the 6004X a low-cost entry point for small-scale deployments. The 6004X is a four-rack-unit (4RU) 10 and 40 Gigabit Ethernet switch with the industry s highest port density in a compact, energy-efficient form factor. It offers eight line-card expansion module (LEM) slots to support up to 96 ports of 40-Gbps throughput. Each LEM supports 12 ports of 40 Gigabit Ethernet in a quad small form-factor pluggable (QSFP) footprint. Each 40 Gigabit Ethernet port can also be split into four line-rate 10 Gigabit Ethernet ports using QSFP breakout cables. This flexibility makes the 6004X the only fully extensible fixed 10 and 40 Gigabit Ethernet platform in the industry. The 6004X also offers a Unified expansion module for 1/10 Gigabit Ethernet and FC/FCoE support. Figure 41: 6004X switch X Switch Expansion Module Options 6004X expansion modules offer multiple interface options with the chassis base. Each 40 Gigabit Ethernet expansion module provides 12 ports of 40 Gigabit Ethernet and FCoE ports using a QSFP interface. With all eight expansion modules installed, the 6004X delivers 96 ports of QSFP or 384 ports of 10 Gigabit Ethernet (SFP+) using the breakout cables. And all expansion modules are hot-swappable. The 40 Gigabit Ethernet expansion module for the 6004X is shown here: Figure 42: 12-Port 40-Gbps line-card expansion module 29

30 switches The 6001 switch is part of a robust fabric that can scale significantly to meet data center growth, delivering architectural flexibility that enables any data center to be a more agile, cost-effective, and efficient environment. The 6001 switch is an important component of the Cisco Unified Data Center architecture, complementing existing switches. The 6001 is an energy-efficient switch that offers high port density in one rack unit (1RU), supports 10 and 40 Gigabit Ethernet and fiber channel over Ethernet (FCoE), provides integrated layer 2 and 3 features at wire speed, and offers low latency of approximately 1 microsecond for any packet size. With a choice of front-to-back (port side exhaust) and back-to-front (port side intake) airflow options, the switch is designed for a broad range of traditional data center and large-scale virtualized cloud deployments. The 6001 switch comes in these configurations: 6001P The 6001P is a 1RU, 10- and 40- Gigabit Ethernet switch offering wire-speed performance for up to sixty-four 10 Gigabit Ethernet ports (using quad small form-factor pluggable [QSFP] breakout cables) for Ethernet and FCoE traffic, with an overall throughput of 1.28 terabits per second (Tbps). The 6001P offers 48 fixed 1/10 Gigabit Ethernet enhanced small form-factor pluggable (SFP+) ports and four 40 Gigabit Ethernet QSFP+ ports. Each 40 Gigabit Ethernet port can be split into four 10 Gigabit Ethernet ports using a QSFP+ breakout cable. The 6001P delivers low port-to-port latency of approximately 1 microsecond and low jitter independent of packet size using cut-through switching architecture and with features enabled. Figure 43: 6001P switch 6001T The 6001T (Figure 2) is a 1RU 10 and 40 Gigabit Ethernet switch offering wire-speed performance for up to sixty-four 10 Gigabit Ethernet ports (using quad small form-factor pluggable [QSFP] breakout cables) for Ethernet and FCoE traffic. It has an overall throughput of 1.28 terabits per second (Tbps). The 6001T offers 48 fixed 1/10G BASE-T and four 40 Gigabit Ethernet QSFP+ ports. Each 40 Gigabit Ethernet port can be split into four 10 Gigabit Ethernet ports using a QSFP breakout cable. The 6001T delivers low port-to-port latency of approximately 3.3 microsecond and low jitter independent of packet size using cut-through switching architecture and with features enabled. Figure 44: 6001T switch 30

31 Leaf-and-Spine Architecture Data center architectures are changing to more efficiently support multiple, high-traffic applications. New, large-scale nonblocking fabrics promote heavy east-west or north-south traffic. The leaf-and-spine design helps ensure low-latency fabric with a low hop count. spine switches create a nonblocking, lowlatency fabric, forwarding packets between leaves. The following graphic shows the 6004X as a spine switches connected to the leaf switches Nexus 6001x, providing connectivity to servers. A highly meshed architecture helps ensure high network availability with minimal impact on customer traffic if a failure occurs. The following graphic shows the spine/leaf architecture: 7000 Core 6004 L3 Spine 6004/ 6001 L2/L3 Fabric Leaf Figure 45: spine/leaf (Fat-Tree) architecture with Nexus 6xxx series (source: Cisco) Structured Cabling for 40 Gb/s Ethernet between spine and leaf switches The following graphic shows the different cabling channel configurations 40 Gb/s Ethernet between the spine and leaf switches: 12 x 40 Gb/s 40G BiDi TYPE 1 40G BiDi 3 x 40 Gb/s 6004x 40G SR 40G CSR TYPE 3 TYPE 4 6 x 40 Gb/s 40G SR 40G CSR 6001x Figure 46: Structured Cabling Model Types for Cisco 6004x 6001x: 40 Gb/s Ethernet 31
