And the increasing requirements of higher speeds in data centers have enhanced the adoption of 25G switch, which is the new buzz in recent years. In this post, a simple analysis of 25G switch market and comparison of commonly used 25G switches will be explored.

25G Switch Market Analysis

As we know, before 25G technology advent, the existing options are one lane for 10G, four lanes for 40G, or four lanes at 25Gbps for 100G. The 25G technology meets the specification for existing module form factors like SFP28 and QSFP28, and allows for a breakout connection between 25G and 100G without changing the port on the front of many 100G switches. Besides, driven by the high speed and bandwidth, various switch manufacturers have announced their new 25G switches in recent three years, just to occupy more market shares.

• Cisco delivered their Nexus 9300-FX platform switches for 10G/25G/100G switching;
• Mellanox launched 25G Ethernet switch SN2410 series for 25G/50G/100G Ethernet networks;
• Dell put forward EMC networking S-series 25/40/50/100GbE to help data centers migration;
• Broadcom announced its BCM56960 Series 25G switch for cloud-scale networking;
• FS.COM introduced N-Series spine/leaf 25G/100G switch for cost-effective data center solutions.

At the same time, 25G optical transceivers, DACs, and AOCs also spring up like mushrooms. According to a study by Dell’oro, Ethernet switch revenue will continue to grow through the end of the decade, with the biggest sales forecast for 25G and 100G ports.

Notes: the source of the research: Crehan research.Inc

From the research we can see, at least in the next three years, 25G/50G/100G bandwidth will continue to grow and occupy half of the total network bandwidth, which in turn enhances the development of 25G switch market. Though challenges still exist for 25G Ethernet, it’s not denied that the trend for ToR 25G switches cannot be blocked.

Comparison Between Commonly Used 25G Switches in the Market

As have mentioned above, 25G switch market is booming due to the growing speed and bandwidth as well as switch vendors promotion. Then how to achieve the optimized network performance with existing 25G Ethernet switches, and control the total investment at the same time? Firstly, let’s have a look at the 25G switches in the market.

All the 25G SFP28 switches listed in the table have the same port configuration: 48 SFP28 ports and 6 QSFP28 uplink ports. And there are ToR/Leaf switches. Usually 25G switch is often used for switch-to-server applications, as for how to realize this, please read the article: How to Use 25G Switch for Switch-to-Server Connection.

For choosing ToR 25G switch, if you have no limited cost budget, Cisco 25G switch maybe a not bad choice, because except for the expensive price, it has high-level performance and configuration as well as its good reputation. All these make Cisco switches are perfect for data centers. Of course, other 25G switch vendors like Dell, Brocade and Mellanox also provide good options for migration from 10G, 25G to 50G and 100G networks.

However, for those who have a tight budget or do not pursue brand, a more wise choices is to select 25G switch like FS.COM N8500-48B6C. This switch supports ONIE installer for 3rd party network operating systems and compatibility with SDN (Software Defined Networks) via OpenFlow 1.3.11. And it also supports the advanced hardware based VXLAN feature to support over 16M virtual networks, making it a suitable option for cost-effective data center solutions.

Summary

25G switch offers a more convenient way to migrate to 100G network. Because it reduces the numbers of cables and switches needed in network designs, which in turn decrease the CAPEX and OPEX. Facing with the fast evolving 25G switch market, are you ready for it?

 

Stack Switch: Optimize Your Network Performance to the Maximum

Stacking switch is a common technology used in network design, especially when large numbers of ports are required in data centers or large size networks. Stack switch not only provides high performance, but also maximizes network scalability and simplify network management. That’s why stackable switches are popular among network builders. Then what is stack switch? What’s the common way for switch stacking in the market?

What Is Stack Switch?

Stack switch, also called stackable switch by vendors, allows several switches to stack via specific stackwise port or uplink port. Traditionally the switches stacked together usually is limited to the same series of network switches. Mixed switch stacking is allowed for today’s switches. The number of stacked switches is often determined by switch brand. For example, Cisco 3850 stack switch can have a maximum of eight switches to be stacked, while Dell N4000 series stack switches are up to twelve. When switches are stacked, all members in this stack share the same IP address and can be managed as “one unit” through the CLI (command line interface) or embedded Web interface, which offers great convenience for network administrators without lowering its performance.

Usually stack switches come with fixed configuration like 12, 24, or 48 gigabit Ethernet ports. Compared with modular switches that allow line cards or service modules in and out as needed, stack switches are more cost-effective in enterprise campus networks which offer endpoint connectivity and uplink capabilities for users at a price per port. Therefore, for those who has limited switch port or enterprise networks that lack of physical expandability, stack switch is an excellent choice for network expansion.

How to Achieve Network Switch Stack?

From the first generation of of Cisco 3750 series stack switches, the stackable switch market has become more mature, so does the switch stacking technology. Like Cisco, other network switch vendors like Dell, Brocade and FS.COM also add their own unique features and functionality to their stack switches, which enhance the virtuous circle of switch stacking technology development.

The typical method for switch stacking is to use stacking cable via stackwise port. Take Cisco 3750 series stack switches for example. Stackwise port lies on the rear-panel. Only approved cables can be used to connect the 3750 stack switches with other similar switches. If not, devices easily get damage. In addition, Cisco offers different connection types for this stack: full bandwidth connection and half bandwidth connection, which provide great flexibility for different application requirements.

Another way to achieve switch stack is to use the uplink ports. As has mentioned, many switch vendors upgrade the switch stacking technology to improve their competitiveness. Today’s stack switches can be stacked using several types of Ethernet ports such as 10GBASE-T copper port, 10G SFP+ fiber port and 40G QSFP+ port. Here take FS S3800-24F4S stackable managed switch as an example. As shown in the following picture, in the stack, one fiber cable from a 10G SFP+ port on a stack switch is connected to a SFP+ stacking port on the next switch. This process is repeated until all of the devices are connected. And the first stack switch is also connected with the last one to complete the stacking topology.

Conclusion

Stack switch, no matter uses stack cable or SFP+ stacking/uplink port, provides high bandwidth port density and easy management for network design. But compared with the way of using stack cable, stacking/uplink port is more cost-effective. Besides, using fiber uplink port to stack switch can realize long distance stacking in different areas, which are more popular in today’s network infrastructures.

What to Consider When Buying PoE Switch for IP Cameras?

As the growing of business and the increasing awareness of security, IP cameras are widely deployed in areas like schools, public areas and even at home. All these arouse the increasing demand for PoE (power over Ethernet) switches which enabling big benefits for IP surveillance system. However, many users may ask a question: how to choose a PoE switch for my IP cameras? 8-port PoE switch or 24-port gigabit PoE switch? Cisco PoE switch or Netgear PoE switch? This post intends to explore the necessary considerations for buying PoE switch.

Understanding How PoE Switch Works for IP Cameras

As we know, power consumption of different IP cameras is different. The power consumption of PTZ (pan-tilt zoom) cameras is up to 20W, while other IP cameras like indoor/outdoor dome IP cameras may just consume as little as 3 or 4W. In addition, PoE switches transmit both data and power for PoE-enabled devices via a single network/Ethernet cables such as Cat5e, Cat6 and Cat6a. Usually, PoE switch comes with multiple ports to support more than two IP cameras. Take a 8-port PoE switch as an example, it can connect IP cameras, NVR, router, etc. Just like the below picture shows.

Essential Considerations When Buying a PoE Switch

There are various questions about buying a gigabit PoE switch in forums and communities. For example, one user ask in forum: “I have 5 IP cameras in a warehouse, two NVRs in the office, considering the distances, which switch should I choose, is 8-port PoE managed switch enough?” Then if you have the same question, what should you do? Here are some necessary factors to consider.

1.Port Count of PoE Switch

This is a basic factor that should be considered when buy a PoE switch. And it is easy to decide how many ports you need. According to the number of PoE-enabled devices, choosing the switch that has larger PoE ports than your device number, which is for your future-proofing upgrade.

2.PoE Switch Power Budget and IP Camera Power Consumption

The power budget of PoE switch matters a lot. Network designers need to know the power consumption for each switch port. It helps users to know how many IP cameras can be deployed. And this is easy to get. Take FS 8-port gigabit PoE managed switch for example, the power consumption per port is 30W (IEEE 802.3at ). Keep in mind that not all PoE port can reach the max. power consumption at the same time. As has mentioned above, the power consumption of IP camera varies from types to types. Therefore, to ensure the normal work of IP cameras, the power budget of PoE switches is important.

 

3.Unmanaged or Managed PoE Switch

It’s known to all that PoE switches come with managed switch and unmanaged switch. People who have experience in network design will know clearly the benefits of managed PoE switches. They enable network administrators to check the quality of the network copper cables linked to each switch port. And administrators also can use advanced management functions to have a good command of the whole network.

4.What’s the Distance of PoE? How to Select Ethernet Cable for PoE Switch?

Usually the transmission of PoE switch is 100m, and the commonly used cable is Cat5 Ethernet cable. According to the IEEE802.3af PoE standard, the required PoE output power is 15.4W. And the PD can receive 12.95W power after 100m transmission. FS PoE switches are compliant with 802.3af/at, which is definitely meet this demand. In addition, standard Cat5 cable is enough for the PoE connections. Make sure the Ethernet cable you buy is a standard network cable.

Summary

Choosing a suitable PoE switch is not an easy work, this post explores several considerations when buying a PoE switch for home or small business networks. If you still have questions about buying a PoE switch, you can do the same work like the user who confused about whether to buy a 8-port gigabit PoE switch or not. asking for help in forums or community, or just consult your sale rap.

Review: Popular 24-Port PoE Switch for Different Size Networks

Purpose built for converged networks where video, voice and data are carried over a single network platform, PoE switches with 8 port, 24 port and 48 port represents an ideal solutions for different size networks like home or SMBs (small and mid-size business networks). 24-port gigabit PoE switch is a relatively commonly used network switch, which in turn cause hot discussions in forums and communities. Then what to consider when choosing a 24-port PoE switch? What’s the popular 24-port gigabit PoE switch to select? This post will give an answer.

Considerations to Choose a 24-port PoE Switch

As we know, the basic types of a network switch are managed switch, smart managed switch and unmanaged switch. Usually, managed and smart managed switches are an optimal choice for SMB applications because of its better control of networks.

Power budget—PoE switches are designed to power devices like IP cameras, VoIP phone, AP, etc. The power the 24-port PoE switch provides should meet the requirements. After all, not all the 24 port on gigabit PoE switches can offer power.

Cost—this factor is that many users care about. Buying a satisfying PoE switch with low cost is a pleasant experience. Here I’d like to say, with the same configuration, not all managed switches are expensive than smart managed switches. Therefore, before buying a 24-port PoE managed switch, try to get more suggestions in related forums or communities like Reddit.

Warranty—do not ignore this factor when choosing a gigabit PoE switch. There are many switch vendors supplying 24-port gigabit PoE switches, but not all manufacturers offer the same warranty. And many buyers are complaint with warranty after buying a network switch.

Switch Stacking vs Trunking: What’s the Difference?

The performance of Ethernet switches is important in network design, for it will affect the whole network system working. Therefore, to achieve high performance, network managers may use different methods to improve performance of network switches, which cause a hot topic: switch stacking vs trunking. In the article, the knowledge of switch stacking and trunking will be explored as well as the comparison between them.

Switch Stacking vs Trunking: Differences in Basic Definition

Switching Stacking

Switch stacking is to connect two or more stackable switches, usually up to nine, through a stack cable and uses Cisco propriety StackWise protocol. Stacked switches can be regarded as one unit, and use the same IP address. The stack master which contains the saved and running configuration files for the switch stack controls the whole stack units and can be replaced if it fails. And stacking connects the backplane of the switches thus having full backplane speed connectivity between the switches.

Figure 1: Stacking of Cisco Stackable Switch

Trunking

Trunking is different from switch stacking. It is a method to handle multiple signals simultaneously. And trunking is often used to form an internetwork including LANs (local area networks), VLANs (virtual LANs) and WANs (wide ares networks). For example, if two switches are divided into four VLANs, and each switch has two VLANs. When communications are needed between the four VLANs, each switch must have a port designated as a trunk port to allow data flows between these VLANs. That’s trunking. Look at the following trunking example of FS 10G switches.

Figure 2: Port Trunking on FS 10G Switches

Switch Stacking vs Trunking: Further Comparison in Parameters

Switching stacking and trunking are two technologies in network management, then what’s the difference between them?

Configuration Requirements

Generally speaking, not all network switches support stacking. Stackable switches must belongs to one vendors when users want to achieve stacking. The original stackable switches are Cisco Catalyst 3750 series. But now more and more vendors like FS are capable of manufacturing stackable switches. The S3800-24T4S 24-port gigabit stackable managed switch and S3800-24F4S 24-port stackble SFP switch are two cost-effective switches for enterprise networks.

However, trunking is different from stacking. Most network switches in market support trunking, which ensure connection between different VLANs. No other special requirements for trunking.

Cost

Usually stackable switches are more expensive than common switches. Because some stackable switches needs additional cable and modules for stacking, which add extra investment for devices. However, there are also switches come with built-in ports for stacking, which can avoid the possible expense of the modules in stacking. FS gigabit stackable managed switches mentioned above are such type of switches, and the price of them is less than $500.

Figure 3: FS S3800 Series Stackable Managed Switches

Performance

When switches are stacked, they becomes one single unit logically. That is to say, the stack unit (up to nine switches) can be taken as “one switch”. There is just a single management interface for users to deal with, which greatly simplify network management, increase port count available and provide high bandwidth at the same time.

Trunking is based on a layer 2 technology. And a 4-byte header is added into each packet as they leave the first switch, and the header will be removed when the packet arrives at the second switch. That’s how trunking work. It eliminates the frequent port configuration when two or more VLANs need communications. In addition, LAG (Link Aggregation Group Protection) is a way to in trunking that protects links from errors.

Conclusion

In fact, switching stacking and trunking are two different concepts, even though both of them can simplify network management. Switch stacking vs trunking, choosing which one depends on users requirements. If high density port and high speed are the first parameter to consider, stacking and stackable switch are a better choice. If not, then trunking can be taken into consideration.

Smart Switch vs Managed Switch: What’s the True Difference?

Ethernet switches can be regarded as the “brain” of a network. In today’s market of network switches, there are mainly three types of Ethernet switches: managed switch, smart switch and unmanaged switch. Like the discussion about managed vs unmanaged switch, the topic of “smart switch vs managed switch” is also be discussed heatedly. Then what’s the true difference between smart switch and managed switch? Let’s have a further look.

Smart Switch vs Managed Switch: Differences lies in Definition

What Is a Smart Switch?

A smart switch provides basic managed switch features such as QoS, security, and web management. Usually, smart switches are managed via a web browser, which provides intuitive guidance for users to manage their networks. If there is no advanced applications needed, smart switch is an optimal solution for simple applications like small and mid-sized business networks.

What Is a Managed Switch?

Managed switch, such as FS S3800-24T24S stackable managed switch, is designed to work for large data center and enterprise networks. Generally speaking, managed switch has a serial port which allow recovery from misconfiguration with minimal downtime. And managed switches have more intelligent functions like port mirroring and monitoring management, which enables users to prioritize network traffic and get high degree control of their networks.

Smart Switch vs Managed Switch: What’s the True Difference?

Differences between smart switch and managed switch have got much attention in both technical forums and communities. Why so many guys are confused with smart switch and managed switch? In the market, to propagate their network switch, many vendors use different terms like smart switch, smart managed switch, web-smart switch to define their switches, which cause troubles for users to understand these terms. Here are some obvious differences between smart switch and managed switch.

Cost

If you search online and you will find that most smart switches in market are slightly crippled versions of managed switches with no CLI or telnet functions. And price seems to be the biggest difference, especially among brand switches like Cisco managed switch and HP managed switch. While some third vendors still supply self-developed managed network switches in a low price.

Performance

Working performance is an important factor to consider when users choose between smart switch and managed switch. Because most managed switches can be accessed by command line interface via a RS-232C console port and telnet and/or SSH session, and often a web GUI. While the so-called smart switches often lack console port, and they may not support telnet, SSH, though they have a web GUI. In addition, smart switches usually have limited selection of advanced management, poorer scope of configuration flexibility and little to no security features.

Summary

Smart switch vs managed switch, the differences do exist. Regardless of which type of network switch you choose, the features that best fit your network are what you should consider first. If you have no limit of expenditure and want to have more control over the network, managed switches are the best choice. If not, smart switches or unmanaged switches can be an alternative.
