Comparison Between Managed Switch And Unmanaged Switch

As an important part of the whole data link, switch has been a hot spot. According to Ethernet standard, it can be divided into 1G switch, 10G switch, 40G switch and 100G switch; according to port configuration, it can be classified as 8 port switch, 16 port switch, 24 port switch and 48 port switch; according to PoE technology, there are PoE switch and non-PoE switch. But, do you know there are managed switch and unmanaged switch? This article will make a comparison between them.

Overview of Managed Switch And Unmanaged Switch

In a networking, a switch receives a message from any device connected to it and then transmits the message to the target device. Within a LAN, the switch can handle and transmit data among multiple devices via a intelligent and efficient way. As for managed switch and unmanaged switch, the key difference between them is that managed switch can be configured and it can prioritize LAN traffic to make the most important data get through; while unmanaged switch is a “plug and play” device. It can’t be configured or analyze the data traffic.

Comparison Between Managed Switch And Unmanaged Switch
  • Managed switch gives you better control over your LAN traffic and offers advanced features to control the traffic.
  • Managed switch has all the features of unmanaged switch and additionally has the ability to configure, manage, and monitor your LAN. So this helps you to monitor and decide who should have access to your network and gives you greater control over data flow through your network.
  • Unmanaged switch does not support any configuration interface and options. It is like plug and play device and you need to connect your computer or other network devices directly to the unmanaged switch. If there are no advanced applications needed, then unmanaged switches should be the best choice.
  • Managed switch uses protocols such as SNMP or Simple Network Management Protocol for monitoring the devices on the network, which helps in the exchange of management information between network devices.
  • Managed switch with Quality of Service (QoS) feature allows you to prioritize your network traffic by assigning a higher priority to the critical traffic. This helps to improve network performance and helps in better transmission of delay-sensitive data such as real-time voice.
  • Managed switch can be used to isolate traffic between different user groups. This segmentation and isolation of network traffic help to reduce unnecessary traffic. For instance, you can segregate traffic between your finance and marketing groups, so that critical finance information can flow without delay to the finance users and not get bogged down by marketing traffic. This allows better network performance and additional level of security.
Conclusion

When it comes to which one to choose, it is mostly about two things: budget and application. Managed switches are costlier than unmanaged switches. But managed switches definitely have more benefits and ensure improved, consistent network performance. Weighing the pros and cons of both the types of switches, each business needs to evaluate its network needs. If you just want to setup a network, unmanaged switches are good enough. If you need configuration options like like VLAN, QoS you will have to use a managed switch. FS.COM can provide quality managed switch, such as 8 port managed PoE/PoE+ switch, 24 port managed PoE/PoE+ switch. Also, they have cost-effective optical transceiver and optical cable.

Set Up 10G Home Network

Nowadays, nobody would deny the importance of the network. It has become an inseparable part of our daily life. As it developed, people’s demand for bandwidth is increasing. And 10G network is widely applied in small and middle sized business. In addition, 10G home network can be also commonly found. This article will share some tips to set up 10G home network.

Consideration Before Setting Up 10G Home Network

Why do you need 10G network? It is not difficult to find that almost everything nowadays rely on a fast and reliable network, which leads to tremendous traffic and applications running on the network. It is necessary to upgrade your home network to support the growing of your business. Setting up 10G home network avoids network congestion at busy times while improves your productivity.

What do you want from 10G home network? Before you start to set up the network, better planning is needed. You should ask yourself a few questions, such as how many computers, printers and other peripherals will connect to your network? How much wireless coverage will you need at your location? What type of mobile devices will need access to your network?

Needs for 10G Home Network
10G Switch

To build a 10G home network, several components are required: 10G core switch, access switch with 10G uplink, and 10G network interface cards for servers and storage devices. The past few years had witness the price dropping of 10G network switch. For example, the cost of Ubiquiti Unifi and Edgeswitch switch are only $200. You can also find many 10G switch under $550, such as FS.COM 10G network switch S3800-48T4S only costs $480 by offering 48 100/1000Base-T and 4 10GE SFP+ ports.

10G switch
10G Cabling

There are two cabling ways for 10G home network—10GBASE-T and 10G SFP+.

If you choose 10GBASE-T, then upgrading the existing 1G network to 10G can be simple. If 10G switch is designed with RJ45 ports, you can use the same RJ45 network cable to connect the 10G switch with your server, storage and some other switches. The only difference is to use Cat6a network cable instead of Cat5e and Cat6 cable, because Cat6a can support 10G data rate over 100 meters; or you can choose SFP+ 10GBASE-T module with 2.5W power consumption and a maximum distance of 30 meters.

10G cabling

For 10G network switch that supports 10G SFP+, you can use it with devices that come with 10G SFP+ ports, too. For server or storage devices with 10G SFP+ port, the most cost efficient way to connect them with 10G network switch is to use 10G DAC cable (direct attach cable). It is basically copper cable with SFP+ connector on both sides. But this cabling way is only suitable for short connectivity. For data link over 100 meters, a pair of SFP+ modules and the matching fiber optic cable are needed. Depending on the length required in home network, you can use 10G optics such as 10GBASE SR SFP module and multimode fiber to reach 300 meters.

Conclusion

For home network set up, 10G is a trend. But before you migrate your network to 10G, you still have to think about what you want or what you need. After that, the choice for components and cabling procedure can be easy. FS.COM provides comprehensive 10G solutions: all the components mentioned to build a 10G home network are available at FS.COM, including 10G switches, network cables, 10G SFP+ transceivers, fiber patch cables and DAC cables.

How to Choose the Right Switch for Your Data Center?

If you plan to set up a 10G network, what do you need? The answer is 10G switch, 10G transceiver and optical cable. In addition, the option of switch is the most basic and important step to start the network deployment. How to choose the right switch for your data center? This article will introduce the three-tiered network model which can help you make a right choice.

Basic Knowledge of Switch

Before we come to the three-tiered network model, let’s learn about some basic knowledge of switch. All switches maintain a media access control (MAC) address-to-port table which is used to intelligently forward frames out the right ports to the intended destinations. Besides, all switches use standards-based protocols to segment traffic using the concept of virtual local area networks, 802.1q trunks and 802.3ad port aggregation. They also prevent network loops using one of the many variants of the 802.1d spanning-tree protocol.

Three-Tiered Network Model

We know that different types of switches have their own characteristics. And we have to compare them before making the decision. Here is an easy way to look at these differences that we can break them up into traditional three-tiered network model. The three tiers are core tier, distribution tier and access tier. Core switches interconnect with other core switches and down to the distribution tier. The distribution tier sits in between the core and the access tier. The access tier connects the entire structure to end devices like computers, printers and servers. To better understand this, here is a figure for you.

The Three-Tiered Network Model

Core Switch

The most striking feature of core switch is speed. The task of a core switch is routing at Layer 3 (the network layer) and switching at Layer 2 (the data link layer). In addition, core switch is high-throughput, high-performance packet and frame mover, which simply moves packets and frames from one core switch to another core switch, and eventually down to the next tier of switches—the distribution tier.

Distribution Switch

The function of distribution switch is connecting the core and access tier together on the network. Since there are many interconnections in a network, and distribution switch has higher port density than core switch, distribution switch also interconnects all access tier switches. What’s more, distribution switch enforces all forms of network policies.

Access Switch

Access switch directly interacts with end-user devices and it connects the majority of devices to the network. For this reason, the access tier typically has the highest port density of all switch types. Also, access switch usually provides the lowest throughput-per-port of all switches. It commonly supports Power over Ethernet, which can power many endpoint devices, including wireless access points and security cameras. Additionally, access switch is better able to interact with endpoints from a security perspective.

Conclusion

Tasks and workloads can be distinct for switches in different tiers. While all switches share universal functions like MAC tables, spanning-tree and trunking, they also have exclusive capabilities performed only within that network tier. Therefore, you have to figure out what type of switch you need. Then, you can buy compatible optical module and cable.
