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.

Figure 2: S5800-48F4S Switch with SNMP Function

Conclusion

What is SNMP and how SNMP works, now I have explained to you. It is an efficient tool to simplify network monitoring works. So using network switch with SNMP function is a convenient way to collect devices’ data and help IT professionals manage the devices efficiently.

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.

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

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.

Gigabit Ethernet Switch Recommendations

A gigabit Ethernet switch can be an inexpensive and easy way to expand your network in your home or small business. After probing into some parameters like brand, popularity, reviews and performance, here is a list of network switches including Ethernet switches for home, port gigabit Ethernet switches, cost-effective gigabit switches etc.

What Does Combo SFP Port Mean For Your Ethernet Switch?

To many noobs who are unfamiliar with the structure and functionality of Ethernet switches may get confused with Combo SFP ports. Combo SFP ports are often labeled obviously. You may have some questions in your mind like what is Combo port and how should I use with it. Since there are many Gigabit Ethernet ports and SFP slots on switches, you may ask whether I used these ports correctly? Don’t worry, this post aims to explain Combo SFP port for your reference.

SFP Transceiver

What Is Combo SFP Port?

A Gigabit Ethernet Combo port is both a copper port, i.e. a RJ-45 interface and a SFP port (also called Mini-GBIC connector). It supports both copper (RJ-45) connections and optional industry-standard SFP modules. Combo SFP ports share the same switch fabric and port number and allow the user to configure their switch according to their application. But you can’t use both of them at the same time. When either of the ports are enabled, the other port is automatically disabled. It means that you can either have a cable plugged into the copper 10/100/1000 interface, or the cable plugged into the SFP slot. If you have both plugged in Combo ports, only one will work. For example, a switch has 12 x 10/100/1000Base-T ports and 2 Gigabit Ethernet Combo ports, therefore it could be configured to have 14 copper ports or 13 copper ports & 1 SFP port, or 12 copper ports & 2 SFP ports, etc.

A Combo port is a way to provide different types of connectivity without taking up unused switch fabric, giving users the power and flexibility to configure their switch for their unique application requirements.

Introduction to FS.COM 24-Port Switch With 4 Combo SFP Ports

There are many switches with combo SFP ports, such as Linksys LGS318 which is a 18-port Smart Gigabit Switch with two combo shared ports and Netgear ProSafe 24-port Gigabit Switch with 2 Gigabit Combo SFP—JGS524F. Today I’m going to recommend FS.COM 24-port switch with 4 Combo SFP—S3800-24F4S.

24 port switch with 4 combo sfp

S3800-24F4S 24-port Gigabit switch is designed to meet the demand of cost-effective Gigabit access or aggregation for enterprise networks and operators customers. The Combo SFP ports—a single interface with dual front ends (an RJ-45 connector and an SFP module connector) on S3800-24F4S 24-port switch facilitate the use of different connectivity, making it more flexible to configure the switch. It has a console port, 4 × 1GE Combo ports, 20 × 100/1000Base SFP ports and 4 × 10GE SFP+ ports. It offers up to 128Gbps switching capacity to simultaneously process traffic on all ports at line rate without any packet loss.

Conclusion

Generally speaking, Combo SFP ports are labeled by vendors. If you can’t tell, here is a way to help you identify. Identifying a combo port is based on the interface identifier on the switch panel. If two ports have the same ID but connect to different transmission media, the two ports are multiplexed as a combo port. Then you can run the display interface command to display the combo port. If you need any 24-port switch or any other Ethernet switch, welcome to consult FS.COM.

They allow administrators visibility and control. But the benefits of managed switches are more than this. The following text will cover what managed switches can do and where 24 port PoE switches are used for your reference.

Why Should Choose Managed Switch Over Unmanaged Switch?

A managed switch can seriously expand the long-range flexibility of your network and it can adapt to changing priorities. As your organization grows, your business needs will continue to evolve. Having a device that can respond to the dynamic shape of your operation is a good investment. There are several reasons why a managed switch is recommended:

  • Managed switches have all the features of an unmanaged switch and additionally have 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.
  • If there is an unused port on your managed switch, you can disable that port or even apply MAC address filtering so as not to allow unauthorised users or devices to access the network by just plugging in. So you can secure your network connections and also protect any unused ports on your switch.
  • A major advantage of managed switches is the failover redundancy they add to your network, helping to achieve less network downtime. Managed switches incorporate Spanning Tree Protocol (STP) to provide path redundancy in the network. This provides redundant paths but prevents loops that are created by multiple active paths between switches.

Where Are 24-Port Managed PoE Switches Used?

What are some of the ways a 24 ports PoE managed switch can enhance your organization’s networking capabilities? We need not look any further than the devices these switches connect. Some of the many things a 24-port PoE switch may be used for are:

overview of PoE managed switch

Note: S1400-24T4F managed PoE switch comes with 24x 10/100/1000Base-T RJ45 Ethernet ports, 1x console port, 2x combo port, and 2x gigabit SFP slots.

IP Cameras

To power an IP megapixel camera network, you’ll need a total power per port of 30W. For a 24-Port gigabit PoE managed switch with a power budget of 360W, you can continue to add IP cameras until you reach your budget. If you have 2 SFP ports, you can also connect to multiple switches, as well.

PoE Wireless Access Points (WAPs)

PoE WiFi access points (WAPs) require roughly 30 watts per port for efficient functioning. When you adopt PoE managed switches, installation of controllers and access points is greatly simplified. You won’t need to provide separate power cables or install plugs near wi-fi locations. You’d simply run your Cat5e or Cat6 Cable from your HotSpot to your switch and leave it alone.

Thin Clients

According to wikipedia, thin client is a lightweight computer built to connect to a server from a remote location. It has a barebones design and rely heavily on servers, which allow customers to get access to virtual desktop applications. Furthermore, it help lower costs by about 97%. Since they can access applications, sensitive data and memory from a data center via a managed PoE switch, they have no hard drive.

Conclusion

Since a managed switch has much more advantages over an unmanaged one. It’s necessary for you to have a managed switch in your network. In many cases, future-proofing with a better PoE switch (with more ports) may actually be a much better investment than smaller switches that have fewer ports. Thus, 24 port PoE switch is recommended here.
