Web Smart Switch vs Managed Switch

Speaking of today’s market of network switches, there are three main fiber switches having to be mentioned: unmanaged switch, managed switch and web smart switch. In the previous articles, we compared managed switch with unmanaged switch for home network. In this article, we will continue to make a contrast. So web smart switch vs managed switch, which one should you choose, the decision depends on the size of your network and how much control you need over that network.

alt Web Smart Switch vs Managed Switch

What Is Web Smart Switch?

A web smart switch, also named smart switch or smart managed switch, is a popular option for mid-sized networks that require management. It provides features like QoS (Quality of Service), RSTP (Rapid Spanning Tree Protocol), SNMP (Simple Network Management Protocol), CLI (Command Line Interface), LACP, VLANs, redundancy capability, and so on. Web smart switch is managed via a web browser that provides intuitive guidance for users to manage their networks. It has limited selection of advanced management, poorer scope of configuration flexibility and little to no security features.

What Is Managed Switch?

Similar to web smart switch, a managed switch can be configured and managed correctly to provide a more tailored experience for users. It not only offers tools and means to monitor the network but also gives the network administrator greater control over managing and prioritizing LAN (local area network) traffic. Managed switch allows users in charge of setting everything up, but users have to take all the responsibility for the operation.

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

The differences between web smart switch and managed switch have always been discussed. Here are some obvious differences between them.

Function

Web Smart Switch
  • It offers options like QoS, VLANs, and so on.
  • It’s ideal for VoIP phones, small VLANs, and working groups for places like labs.
  • It allows you to configure ports, basic settings and set up virtual networks.
  • It allows you to assign higher priority to critical traffic.
  • It can divide your network into multiple virtual networks for better traffic security and reliable connectivity.
  • It helps to allocate network bandwidth the way you work.
Managed Switch
  • It provides high-levels of network security, control and management.
  • It can limit access to specific devices, prioritize user traffic and partition a network.
  • It can use layer 3 routing capability to link smaller networks into much larger business-wide networks.
  • It can remotely monitor network performance, detect and repair network problems without having to physically check devices or requiring network services.
  • It can optimize a network’s speed and resource utilization.

Application

A web smart switch is an entry-level managed switch. It’s especially suitable for a business network hosting less than 100 active users. If there is no advanced applications required, web smart switch is the best solution for simple applications such as small and midsize enterprise networks.
An managed switch is ideal for businesses that need to remotely and securely manage and troubleshoot their network. It enables network managers to monitor and control traffic to achieve optimal network performance and reliability. It allows the network to be expanded with flexibility.

Price

Considering the features and functions provided by web smart switch and managed switch, there is no doubt that managed switch is more expensive than web smart switch. Since managed switch allows the network to grow in the future, it worth the price over time.

Web Smart Switch vs Managed Switch: Which Is Best for You?

Web smart switch vs managed switch, the differences do exist. No matter which type to choose, you have to consider your demands first. If you have no limit of expenditure and want to have more control over the network, managed switch is the best choice. If you want to support one small company or colleague with a lower price, web smart switch is good enough. If you don’t know which one suits you best, FS.COM provides various switches to satisfy all your needs.

Managed vs Unmanaged Switch: Which One Can Satisfy Your Real Need?
Managed or Unmanaged Switch for Home Network

Managed or Unmanaged Switch for Home Network

A network switch is a computer networking device, which uses packet switching to connect devices together on a computer network in order to receive, process and forward data to the destination device. There are two common types of switch: managed switch and unmanaged switch, both of which play an important role in home network. So should I use managed or unmanaged switch for home network?

Managed or Unmanaged Switch for Home Network

What Is a Managed Switch?

A managed switch can be configured and managed correctly to provide a more tailored experience for users. It not only offers tools and means to monitor the network but also gives the network administrator greater control over managing and prioritizing LAN (local area network) traffic. Managed switch allows users in charge of setting everything up, but users have to take all the responsibility for the operation.

What Is an Unmanaged Switch?

An unmanaged switch, on the contrary, is a plug-and-play switch that already has all the required program settled, and does not require user intervention, setup or configuration. Here’s one thing to note: the unmanaged switch is manufactured with a standard configuration that cannot be changed, you should think twice before you buy it.

Managed or Unmanaged Switch for Home Network?

Managed switch is able to be configured for more advanced functions while unmanaged switch can’t. Knowing the differences between the two will do a favor in selecting managed or unmanaged switch for home network.

Differences and Similarities Between Managed and Unmanaged Switch

Similarities
  • They allow multiple devices to connected to the network to communicate with each other.
Differences
  • An unmanaged switch is a “plug and play” switch, simply allows Ethernet devices to communicate with one another, such as a desktop PC or router.
  • A managed switch not only provides all the features of an unmanaged switch but also gives you the tools and means to monitor your LAN traffic for a stable and ideal network.
  • A managed switch prioritizes through configuration changes whereas an unmanaged switch is shipped with a fixed configuration and does not allow any changes to this configuration.

Managed Switch for Home Network

A managed switch offers high-levels of network security. It incorporates STP (Spanning Tree Protocol) to provide path redundancy to keep your network safe. So if you need to handle some sensitive information at home, we recommend going with managed switch. It is able to implement VLANs, which allow network administrators to group devices together without running new cables or changing the network infrastructure, to prioritize user traffic for a better performance in a network. A managed switch allows you to configure port mirroring to forward copies of traffic to a single port on the same switch for analysis by a network analyser. The benefit of using managed switch at home is you can diagnose and fix problems without taking the network out of service. In short, a managed switch is ideal for operations that require monitoring and control capabilities. It costs the most, but worth the price over time.

Unmanaged Switch for Home Network

However, an unmanaged switch will work in the most basic form. It can’t be modified or managed. It allows your devices to connect with one another, handles everything automatically. If you’re using unmanaged switch in your home or a small network of fewer than 5-10 computers, it provides ample support. To sum it up, an unmanaged switch is ideal for primary learners with cheaper price.

Conclusion

Now that you know the advantages of managed and unmanaged switches, also the differences between them, you should be able to decide managed or unmanaged switch for home network. For home network, managed switch is for configuring, managing, and monitoring, while unmanaged switch is for simple operating, low in cost. If you are still unsure about the features mentioned above or are confused about the problem confronted, please do not hesitate in getting in touch with FS.COM, we will be more than happy to help with your networking needs.

Managed vs Unmanaged Switch: Which One Can Satisfy Your Real Need?

Top of Rack VS End of Row: Which to Choose for Data Center Network

The topic, top of rack vs end of row, has been under a hot debate when IT technicians talk about data center designs. With the ever-increasing demand for switch-to-server connections in the data center network, the network cabling is required to be more flexible and effective than ever. In that way, a large of installations for greater computing power can be satisfied. Thus, the two commonly deployed designs (top of rack vs end of row) have been put in the spotlight.

Top of Rack (ToR) Design

In a Data Center, there are several racks of servers or storage equipment. Each rack contains multiple computing devices. The top of rack architecture recommends network fiber switches should be placed in every rack to connect with all the computing devices in the rack. In turn, these network switches will be connected to aggregation switches via fiber optic cables.

Top-of-Rack Network Connectivity

Figure 1: Top-of-Rack Network Connectivity

Notably, the top-of-rack switch, like a gigabit Ethernet switch, can be put anywhere in the rack, not just limited at the top. However, when in applications, the engineers prefer to put on the top instead of the middle or bottom of the rack for their easier accessibility and cleaner cable management.

End of Row (EoR) Design

In the end of row design, each server in individual racks is required to connect with a common aggregation switch directly, without connecting to individual switches in each rack. Usually, aggregation switches are placed at either end of the “server row” for the purpose of providing network connectivity to the servers within that row. In light of that, the aggregation switch is also called the end of row switch. With such a design, each server cabinet will have a bundle of twisted pair copper cabling containing as many as 48 (or more) individual cables routed to the end of row switch.

End-of-Row Network Connectivity

Figure 2: End-of-Row Network Connectivity

Just like the top-of-rack switch, the end of row switch may not just be placed at the end of each actual row. Even just a handful of network racks collectively placed in a small row of their own, the end of row switch is still available to provide copper connectivity for more than one row of servers.

Top of Rack vs End of Row

Top of rack vs end of row data center designs are both popular options for data centers and other network arrangements calling for connections with a large number of servers. In fact, it’s hard to decisively say which type is best. Every type shares both advantages and disadvantages.

Advantages

The top of rack switching can relieve the complexity of cabling and increase the efficiency of on-site deployment. For the reason that all the servers in the same server cabinet are connected to the switch, like 10GBE switches in the same rack, only a few cables go outside the rack reaching to the aggregation switch. In thus doing, fewer cables are installed between the server and network racks, which contributes to a reduction of cable cost. Moreover, this design enables easily upgrade from 1GE/ 10GE network to 10GE/ 40GE network in the future with minimum costs and changes to cabling.
In the EoR design, the number of the device is decreased because not every rack needs to be equipped with switches. Undoubtedly, less rack space is required in the architecture. With fewer devices in the data center, requirements for the cooling system will be reduced which also can save the electric power.

Disadvantages

For the ToR, with cables reduced, the number of racks is still increased. The management for switches will be a little bit tricky. In addition, the ToR approach takes up more rack space for the installation of switches.
As for the EoR, with fewer switches used, more cables are needed between racks resulting in the higher possibility of cable mess and higher cost for higher performance cables. Besides, it’s difficult and more expensive to upgrade cabling infrastructure to support higher speed network. Lengthier cables need to be replaced individually while upgrading from 1GE to 10GE, for example.

Conclusion

Top of rack vs end of row data center designs are the common deployments for data center architecture. Considering that each type bears with benefits and limits, you can hardly tell which one is best. Just as the saying, the most suitable, the best.

Managed Gigabit Switch Buying Guide

Nowadays, the managed Gigabit switch has been a hot cake in small and medium enterprise networks. In the context of that, it’s necessary for us to catch the trend and learn something about the managed Gigabit switch so that you can buy it more wisely.

What Is Managed Gigabit Switch?

Before we introduce the managed gigabit Ethernet switch, let’s overview the background information of it firstly. Gigabit Ethernet switch, also called network switch, refers to a box-like device connecting together a number of other devices, such as computers, printers, and servers on a Local Area Network (LAN) and utilize the packet switching to forward data to and from those connections.

While a managed switch is a kind of fiber switch offering a more tailored experience to users. It not only offers tools and the means to monitor the network, but also control over LAN traffic. Managed switches are very much like Virtual Private Servers where you’ll be in charge of setting everything up, managing the device and take responsibility for any configurations that cause downtime.

1GE PoE+ Series Managed Switches

Figure 1: 1GE PoE+ Series Managed Switches

How to Choose a Managed Gigabit Switch as Required?

According to different features and standards, such as the managed level and the number of ports, the managed Gigabit switch can be grouped into different types. And users can select the required managed switches based on these features.

Managed Level

Based on different managed levels, the managed Gigabit switch can be grouped into the partially managed (smart) switch and fully managed (enterprise) switch. Smart switches have a limited number of options for configuration. However, comparing with the fully managed switch, it can be a cheap managed gigabit switch for home and office use. While fully managed switches are targeted at servers and enterprises, offering a wide array of tools and features to manage the complicated network better.

Number of Ports

Classified by the number of ports, the managed Gigabit switch has been known in a different way. Typically, there are four types are commonly found in the market: 8-port managed gigabit switch, 16-port managed gigabit switch, 24-port managed gigabit switch, and 48-port managed gigabit switch. These ports may be a combination of SFP or SFP+ slots for fiber connectivity, but more commonly they are copper ports with RJ-45 connectors on the front, allowing for transmission distances up to 100 meters. With fiber SFP modules, the distances can be supported up to 40 kilometers.

8-Port Gigabit PoE+ Managed Switch with 2 SFP

Figure 2: 8-Port Gigabit PoE+ Managed Switch with 2 SFP

Buyers Guide

After we have a basic idea of types of managed Gigabit switches. it’s time to remind you some factors should be taken into consideration when you buy a managed Gigabit switch. Firstly, you should clear about the location you want to install whether just for home, office or enterprise. It decides that whether you need to buy a partially managed switch or a fully managed switch.

Then you should review your network environment and think about the number of users your network supports. In a short, the larger your organization is, the more ports you’ll need. For example, if you are a home user, an 8 or 24 port switch is enough, but a 48 port switch, designed for medium or larger network environment, will be a waste of resource.

24-Port Gigabit PoE+ Managed Switch with 4 SFP

Conclusion

Through this idea, we can have a basic mind about the background information of the managed Gigabit switch, such as meaning and types. Moreover, we also offer some tips for people who want to buy it. Hope this article can help you choose a right managed Gigabit switch.

What Is SNMP and How SNMP Works

IT System administrators are responsible for collecting work details of the servers and infrastructures, so as to provide a reference for subsequent network adjustment and improvement. But it’s a difficult task in large systems with hundreds or thousands of devices. SNMP protocol is born to solve this problem that lets the technicians monitor the network devices such as data switch, routers and other devices from a single management host. So what is SNMP, and how SNMP works?

What Is SNMP?

SNMP, also written as Simple Network Management Protocol, is an Internet standard protocol implemented on the application layer. The protocol was created in 1898 as a way of monitoring network performance, error rates and so on. The main purpose of SNMP is to define a unified interface and protocol for devices of different categories, versions and manufactures. Thus, assisted by SNMP, system administrators can remotely monitor and manage the numbers of systems and devices on a network, which can greatly simplify their work and improve efficiency of network administration.

How SNMP Works?

Knowing what is SNMP, here we focus on how SNMP works. In SNMP tutorial, to monitor network effectively, SNMP relies on an architecture consisting of the three parts.

SNMP managers: They can be any type of network machine including but not limited to PoE network switch, access servers, etc that has run SNMP to collect and process information of the devices on the network.

SNMP agents: They are the network-management software modules that run on the network node. They are responsible for gathering local system’s information and translating it to an SNMP-specific form.

Network management station: It’s the base that is shared between agents and managers. And it offers the memory and processing resources to the network.

SNMP works by sending message which is called protocol data units (PDUs) between SNMP managers and agents. Using SNMP queries, the manager can identify and locate the devices by receiving the responses sent by the agent. Then the monitoring tool will record and analyze the information of device performance. Thus, the administrators can manage the devices through SNMP control commands. The following picture shows how SNMP works.

what is SNMPFigure 1: Picture of How SNMP Works

Using SNMP to Monitor Network Device

To help IP administrators solve monitoring issue, FS.COM has released a series of switches including 10gbe switch, 40gbe and even 100gbe switch that are equipped with SNMP function.

The S5800-48F4S is a low latency L2/L3 switch with 48 1GbE SFP ports and 4 10GbE SFP+ ports. It supports MLAG, MPLS, SNMP etc, which is perfect for traditional and fully virtualized data center. As for the SNMP configuration, first you should enter the switch administrative interface. Then find the SNMP tab, and select Enable. And follow the commands to create your SNMP account. Thus, you already are enabled to use SNMP to monitor your network.

Things You Should Know about IP SAN vs FC SAN

Now, data has become the most valuable asset since the Internet and e-commerce are growing at an explosive rate. How to store, protect and manage vital data in an effective way is a big challenge for IT technicians. Here, SAN, storage area network, has been developed to provide a creative model for data storing in the data center. Within its development, two types of IP SAN vs FC SAN has gained enough discussion. Today, we’ll talk about IP SAN vs FC SAN.

SAN

Figure 1: SAN Diagrammatic Drawing

What Is IP SAN

From IP SAN wiki, we know it means internet protocol storage area network. It’s a SAN that uses iSCSI protocol, a transmission standard over TCP/IP, to transfer block data over an Ethernet network. IP SAN allows different servers to access pools of the shared block storage devices by storage protocols. Besides, IP storage network can be extended to Wide Area Network via IP router or Gigabit Ethernet switch, which is good for synchronous applications like remote disk copy.

Advantages:

In addition, IP SAN brings several advantages.

  • Low cost. Ethernet, switches and IP network exist almost everywhere. There’s no need to buy extra equipment for connectivity. You can use the existing network to build a SAN.

  • Easy access. The IP technology makes it easier to achieve remote storage. Also, there’s no distance limitation over LAN/WAN connectivity.

  • Competitive speed. Thanks to the advent of 10G Ethernet and 10gbe switch, the transmission bandwidth has been increased. This leads to an improvement of the overall performance.

What Is FC SAN

FC SAN is a fiber channel network in which the SCSI-FCP protocol runs. Based on fiber channel technology, technicians use fiber switch to connect the storage devices and the servers, so as to build a regional network dedicated to data storage. Within FC SAN, the data will be transferred directly at an extremely high speed.

Advantages:

As an open, high-speed serial interface, FC SAN has some advantages.

  • High transmission bandwidth. Due to the design of fiber channel, it can deliver data at 1Gb/s, 2Gb/s, 4Gb/s, 8Gb/s and more. Also, the fiber channel can provide excellent redundancy.

  • Flexibility and extensibility. FC SAN has overcome the traditional cable limits that are associated with SCSI. Thus it greatly expands the distance between servers and storage devices, in order to increase the possibility of more connections,

  • Wide application. As the technology matures, FC SAN is widely used in big IT User Base.

IP SAN VS FC SAN

Figure 2: IP SAN and FC SAN

IP SAN vs FC SAN: What Is the Difference?

Here is a table shows the differences of IP SAN vs FC SAN.

IP SAN
 FC SAN
 Network  Gigabit Ethernet network  fiber channel network
 Cost  Low  High
 Transmission speed  Fast  Extremely fast
 Transmission protocol  fiber channel TCP/IP
 Extensibility  More easier to extend  Easy to extend

IP SAN vs FC SAN, IP SAN is generally regarded as the lower cost, simpler to manage than the FC SAN. FC SAN needs special hardware like fiber switches or host bus adapters, while the IP SAN just requires the existing Ethernet networking hardware. Therefore, FC SAN is the ideal storage platform for many business-critical applications. And IP SAN is the suitable choice for those organizations that want a cost-efficient solution.

Conclusion

IP SAN vs FC SAN, it’s important to know their advantages and differences when you decide to build a SAN. Make a suitable choice based on your unique demands and knowledge. Any questions about SAN setup on switches, contact us via sales@fs.com.

VLAN vs LAN: What Is the Difference?

LAN is widely used in the network to allow computers to connect with different computers of one limited area like a school, factory or building. While VLAN is functioned as a tool to improve Ethernet scalability. Yet, with regard to VLAN vs LAN, what’s the relationship between them and is there any differences? Hope you can find the answers in this article.

VLAN vs LAN—Definition

What Is LAN

LAN is short for local area network, which can connect multiple computers in one location for sending data among themselves. It can be comprised of two computers in an office or thousands in a company, sharing a network that is closed to outside use. Today, LAN is defined as a single broadcast domain. This means within this LAN, if one broadcasts message, all the others can receive it. Also, functions like file management, printer sharing and working group scheduling can be realized by LAN, which will help to improve working efficiency.

VLAN vs LAN-LAN example

Figure 1: LAN Example

What Is VLAN

As the name implies, VLAN, or virtual LAN, is a type of LAN which improves the capability of a flat LAN. VLAN is the logical separation of LAN that can create several LAN segments in one bandwidth regardless of devices’ physical locations. Thus, technicians can use a fiber switch to segment a LAN into different broadcast domains (VLANs). Because the separations are logical ones, users on different floors of one building or different buildings now can share the same LAN.

VLAN 图

Figure 2: VLAN Example

VLAN vs LAN—Differences

Basically, the need of implementing VLAN is to segment the network, which determines the differences when VLAN vs LAN. Initially, physical LANs mean that all working computers were connected to the same cable or sets of chained hubs. It’s a typically flat LAN. But with the technology develops, the demand of working computers on the LAN also grows. When one user wants to deliver a packet, he may find that the wire is already occupied by others’ packet. To solve this problem, the LAN should be split to eliminate the congestion and load. Only use Gigabit Ethernet switch or bridge can create VLANs. Since they’re logical separations, they can reduce the packet traffic. With a VLAN, it’s possible that working computers connect together on the same physical LAN but unable to communicate directly. The following table shows clearly the differences between VLAN and LAN.

Segment LAN into VLANs

Knowing the differences between VLAN and LAN, we know how VLAN and LAN work. As switches are available, FS.COM offers 1GbE switch, 10GbE switch, 40GbE switch and 100GbE switch that support VLAN to optimize your network experience. Here is one S3800-24F4S 24-port Gigabit stackable SFP managed switch for your reference.

How Much Do You Know About Gigabit Ethernet Switch?

In computer networking, an Ethernet switch connects multiple devices, such as computers, servers, or game systems, to a Local Area Network (LAN). Small business and home offices often use an Ethernet switch to allow more than one device to share a broadband Internet connection. A gigabit Ethernet switch operates in the same way, only differentiating in data rates. Gigabit Ethernet is much greater than standard or Fast Ethernet. People can use these switches to quickly transfer data between devices in a network, or to download from the Internet at very high speeds. Gigabit Ethernet transmits at approximately one gigabit per second. That is at speeds nearly 10 times those of Fast Ethernet, which transfers data at approximately 10 megabits per second. The gigabit Ethernet switch is designed to work at these increased speeds, without signal loss or transfer rate reduction.

Gigabit Ethernet Switch: Managed or Unmanaged?

Gigabit Ethernet switches are either managed or unmanaged. Usually an unmanaged switch is referred as a “dumb switch”, which can be easily operated by every noob. It behaves like a “plug and play” device. A basic unmanaged gigabit Ethernet switch has no user configuration. It is placed in the network with the cables plugged in and the unit turned on, and there is nothing else to do. In contrast, a mangaed gigabit switch can be configured, and can be monitored and adjusted at your discretion, such as adjust speeds, combine users in subgroups, monitor traffic and report network activity. Although a managed switch is typically more expensive than an unmanaged switch, it offer much greater flexibility.

Gigabit Ethernet Switch or Ethernet Hub?

Although an Ethernet switch is sometimes called a hub, because a switch performs the same job as a hub, there is a huge difference between a true hub and a gigabit Ethernet switch. An Ethernet hub is a device that connects multiple Ethernet devices to a single network. A hub does not gather information and input in one port results as an output in all ports on the network. While a gigabit switch is considered as a more intelligent hub, because it gathers information about the data packets it receives and forwards it to only the network that it was intended for.
