Use 10Gbase-t Switch to Upgrade Network

The need for 10 Gigabit Ethernet spans all markets and business types. And 10G copper switch wins broad deployment due to its great design flexibility, infrastructure simplification and other advantages.

With 10Gbase-t support, 10G copper switch, or 10Gbase-t switch, enables a standard RJ45 Ethernet jack. And existing copper Ethernet cables can be used to deliver network performance increase to 10GbE while minimizing network changes (cat6 up to 45 meters, cat6a/cat7 up to 100 meters). This post will have an introduction to the 10G copper switch. Why, and how to use 10G copper switch?

Why Use 10Gbase-t Switch?

First of all, compared to other 10G connections, such as SFP+ fiber and SFP+ DAC, 10G copper switch or 10Gbase-t switch offers IT managers a far greater level of flexibility in connecting devices in the data center and accommodating top of rack, middle of row and end of row network topologies. In addition, 10Gbase-t switch, working with existing structured cabling systems, provides IT managers the most flexibility in server placement.

Table 1: 10Gbase-t switch has greater design flexibility compared to other 10G alternatives.

SFP+ Fiber Top of Rack (ToR) Uplinks from ToR switches to aggregation layer switches
Middle of Row (MoR) Inter-cabinet connectivity from servers to MoR switches
End of Row (EoR) Inter-cabinet connectivity from servers to EoR switches

IDA/HDA/MDA Intermediate, Horizontal and Main distribution areas as outlined in TIA 942-A
MD/ZD/EO Main Distributor, zone distributor and Equipment Outlets as outlined in ISO 24764

Second, as 10Gbase-t is backward compatible with 1000base-t, the 10Gbase-t switch will be able to auto-negotiate/select and communicate effectively with legacy Gbit/s and 100Mbit/s server connections that are cabled with cat6 and cat6a cabling. While for any fiber based systems that cannot support lower speeds, wholesale rip and replace server upgrades may be required in addition to 10GbE switch upgrades. Thus 10G copper switch can help IT keep costs down while offering easy migration to 10GbE.

In a word, 10Gbase-t switch provides the most flexibility, the lowest cost media and is backward compatible with existing Gigabit Ethernet networks.

Use 10Gbase-t Switch to Upgrade Network

It’s simple to use 10G copper switch, you can use the same familiar RJ45 network cable to connect the 10Gbase-t switch with your servers, storages and other switches, and they go up the same 100 meters as in the Gigabit network. Just make sure you pick up a cat6a RJ45 cable. Here takes FS.COM 48 port 10Gbase-t aggregation switch with 40gb QSFP+ uplink (S5850-48T4Q) as an example to show the 10Gbase-t solution.

FS.COM S5850-48T4Q 48 Port 10Gbase-t Switch with 40gb QSFP+ Uplink Overview

The S5850-48T4Q 48 port 10Gbase-t switch with 4 QSFP+ comes with 48x 10GE Base-T Ethernet ports, 4x 40GE QSFP+ Ethernet ports and management & Console ports (RJ45). All the 10Gbase-t copper ports can auto-negotiate 100Mbit/s, 1 Gbit/s and 10 Gbit/s by requirements. And every 40G QSFP+ port can be configured into four 10G SFP+ links via breakout cables, so the maximum 10GbE density can be up to 64. On the back panel, it has 4 (3 + 1) pluggable redundant fans and 2 (1+1) hot-swap power supplies. The temperature and status of fans and power supply are real-time monitored by the system. In addition, the switch fan supports intelligent speed control function, green and energy-saving. This 10G copper switch has low power consumption and low latency and supports QinQ and vlan translation, MSTP, ERPS, port-block and storm control (unicast/broadcast/multicast).

S5850-48T4Q 48 Port 10Gbase-t Aggregation Switch Deployment Architectures

As stated above, 10Gbase-t switch can be deployed in various architectures like ToR, EoR, etc. Here will introduce these two different architecture deployments. Each of them has distinct benefits and constraints, therefore which to implement is typically based on the preferences of data center manager, the existing facilities, equipment layout, and the applications being run. Generally speaking, ToR is more common due to easier accessibility and cleaner cable management.

ToR (Top of Rack)

In ToR architecture, the S5850-48T4Q 48 port 10Gbase-t switch with 4 QSFP+ uplink , residing at the top of each server rack, provides the flexibility of connecting existing 1000base-t or older switches and servers to newer 10GbE equipment using cat6a patch cords. Generally, 10Gbase-t aggregation switch is well suited to ToR architecture in the following situations:

 New data center without any existing cabling or equipment  Need for scalability and ease of adding cabinets  Ease of migration from 10G networking toward 40G  High-density layouts using large numbers of servers per cabinet  Reduced cable congestion  Modular, pre-configured cabinets

EoR (End of Row)

Standard structured cabling practices are used in the EoR to provide efficient cable organization, allowing the user to take optimal advantage of 10Gbase-t switch. Cat6a cables can be used for the vast majority of connections between switches, fabric extenders, and servers, due to the 100-meter reach and backward compatibility of 10G copper switch. The utilization of RJ45 copper patch panels can simplify management and changes to the environment while helping to reduce the potential for airflow blockage. Typically, 10Gbase-t  switch is well suited to EoR architecture in the following situations:

Existing EoR networks with base-t cabling—currently the most common layout  Compatibility with existing GbE or slower networks  Potential for frequent network changes, which are easier to do with structured cabling Centralized security and network management  Sensitivity to downtime and strong value on redundancy  Optimized port utilization

Summary

10G copper switch, or 10Gbase-t switch, which can be used for all data center architectures, is well suited for widespread use in today’s networks. With the advantages of high flexibility for new data centers and the easiest upgrade path for existing ones, 10G copper switch simplifies data center infrastructure, and can meet the demands of virtualized and ever-flattening networks. The combination of reliability, flexibility, backward compatibility, cost-effectiveness, ease of use, and a 100-meter reach makes 10Gbase-t switch an ideal choice for next-generation networks.
