Understanding Data Center Redundancy

Maximizing the uptime should be the top priority for every data center, be they small or hyperscale. To keep your data center constantly running, a plan for redundancy systems is a must.

What Is Data Center Redundancy?

Data center redundancy refers to a system design where critical components such as UPS units, cooling systems and backup generators are duplicated so that data center operations can continue even if a component fails. For example, a redundant UPS system starts working when a power outage happens. In the event of downtime due to hazardous weather, power outages or component failures, data center backup components play their role to keep the whole system running.

Why Is Data Center Redundancy Important?

It is imperative for businesses to increase uptime and recover more quickly from downtime, whether unexpected or planned. Downtime hurts business. It can have serious and direct impact on brand images, business operations, and customer experience, resulting in devastating financial losses, missed business opportunities and a tarnished reputation. Even for small businesses, unscheduled downtime can still cost hundreds of dollars per minute.

Redundancy configuration in data centers helps cut the risk of downtime, thus reducing losses caused by undesired impacts. A well planned redundancy design means shorter potential downtime in the long run. Moreover, redundant components also ensure that data is safe and secure as data center operations keep working and never fail.

Redundancy is also a crucial factor in gauging data center reliability, performance and availability. The Uptime Institute offers a tier classification system that certifies data centers according to four distinct tiers—Tier 1, Tier 2, Tier 3 and Tier 4. Each tier has strict and specific requirements around data center redundancy level.

Different Levels of Redundancy

There is no one-size-fits-all redundancy design. Lower levels of redundancy mean increased potential downtime in the long run. While more redundancy will result in less downtime but increased costs of maintaining the redundant components. however, if your business model requires as little downtime as possible, this is often justifiable in terms of profit and overall net growth. To choose the right configuration for your business, it is important to recognize the capabilities and risks of different redundancy models, including N, N+1, N+X, 2N, 2N+1 and 3N/2.

N Model

N equals the amount of capacity required to power, backup or cool a facility at full IT load. It can represent the units that you want to duplicate such as a generator, UPS, or cooling unit. For example, if a data center requires three UPS units to operate at full capacity, N would equal three.

An architecture of N means the facility is designed only to keep a data center running at full capacity. Simply put, N is the same as zero redundancy. If the data center facility is at full load and there is a hardware failure, scheduled maintenance or an unexpected outage, mission critical applications would suffer. With an N design, any interruption would leave your business unable to access your data until the issue is resolved.

N+1 or N+X Model

An N+1 redundancy model provides a minimal level of resiliency by adding a single component—a UPS, HVAC system or generator—to the N architecture to support a failure and maintain a full workload. When one system is offline, the extra component takes over the load. Going back to the previous example, if N equals three UPS units, N+1 provides four. Likewise, an N+2 redundancy design provides two extra components. In our example, N+1 provides five UPS units instead of four. So N+X provides N+X extra components to reduce risks in the event of multiple simultaneous failures.

2N Model

2N redundancy creates a mirror image of the original UPS, cooling system or generators to provide full fault tolerance. It means if three UPS units are necessary to support full capacity, this redundancy model would include an additional set of three UPS units, for a total of six systems. This design also utilizes two independent distribution systems.

With a 2N model, data center operators can take down an entire set of components for maintenance without affecting normal operations. Moreover, in the event of unscheduled multiple component failures, the additional set takes over to maintain full capacity. The resiliency of this model greatly cuts the risks of downtime.

2N+1 Model

If 2N means full fault tolerance, 2N+1 delivers the fully fault-tolerant 2N model plus an extra component for extra protection. Not only can this model withstand multiple component failures, even in a worst-case scenario when the entire primary system is offline, it can still sustain N+1 redundancy. For its high level of reliability, this redundancy model is generally used by businesses that cannot tolerate even minor service disruptions.

N+1 2N+1 redundancy

3N/2 Model

The three-to-make-two or 3N/2 redundant model refers to a redundancy methodology where additional capacity is based on the load of the system. If we consider a 3N/2 scenario, three power delivery systems will power two servers, which means each power delivery system utilizes 67% of the available capacity. Likewise, in a 4N/3, there will be four power delivery systems powering three workloads (three servers). The 3N/2 could be upgraded to 4N/3, but only in theory. This is because such an elaborate model has so many components that it would be very difficult to manage and balance loads to maintain redundancy.

3N/2 redundancy

What’s the Right One for You?

Choosing a redundant model that meets your business needs can be challenging. Finding the right balance between reliability and cost is the key. For businesses that require as little downtime as possible, higher levels of redundancy are justifiable in terms of profit and overall net growth. For those that do not, lower levels of redundancy are acceptable. They are cheaper and more energy efficient than the other more sophisticated redundancy designs.

In a word, there’s no right or wrong redundancy model because it depends on a range of factors like your business goals, budget, and IT environment. Consult your data center provider or discuss with your IT team to figure out the best option for you.

DWDM Mux/Demux Overview-Working Principle and Different Types

DWDM (Dense Wavelength Division Multiplexing) is a combination of a set of optical wavelengths that can be transmitted with one fiber. This is a laser technology used to increase bandwidth on existing fiber-optic backbones. It enables optical fiber networks to transmit signals of several wavelengths simultaneously. In DWDM system, Mux/Demux are two indispensable components. How do these two components work in DWDM system and how to choose a DWDM Mux/Demux? We have the answers for you in the following contents.

What Is DWDM Mux/Demux

To understand DWDM Mux/Demux, you have to know what DWDM is. DWDM (Dense Wavelength Division Multiplexing) is an optical multiplexing technology used to increase bandwidth over existing fiber optic backbones. The data from various different sources is put together on optical fiber in which each signal travels at the same speed on its own light wavelength. In DWDM system, Mux/Demux are two indispensable modules. Mux (Multiplexer) is a module at the transmitter end that brings several data signals together for transporting over a single fiber, while Demux (Demultiplexer) is a module at the receiver end that separates the signals that come together and passes each channel to an optical receiver. DWDM Mux/Demux modules are made to multiplex multiple DWDM channels into one or two fibers. It can extend the bandwidth of optical communication network with low cost and long transmission distance, which makes it an ideal network solution.

DWDM Mux/Demux

How Does DWDM Mux/Demux Work

The DWDM network structure begins with transponders or transceivers accepting data input from a variety of traffic types and protocols. This forwarder performs the basic function of mapping input data to a separate DWDM wavelength. Each individual wavelength will be fed to the Mux, and the Mux filters and combines multiple wavelengths onto a single output port for transmission through the main DWDM fiber. Then, at the receiving end, individual channels can be isolated by using Demux to separate wavelengths, and each channel can then be routed to the appropriate client-side output via additional wavelength-matched transponders or transceivers. The picture below can be a good reference.


Factors to Consider When Choosing the DWDM Mux/Demux

Line Port

Line port is one of the important ports for each DWDM channel multiplexing and demultiplexing. There are dual fiber and single fiber types of line port, and which to select depends on the use of DWDM wavelengths. As for single-fiber DWDM Mux/Demux, it requires only one single optical fiber to transmit the signals. However, the transmission line can be either unidirectional or bi-directional. Single-fiber unidirectional indicates that optical modules are connected through only one optical fiber and signals can only be sent from the transmitter to the receiver, not in reverse. The advantage of this transmission is that the system is relatively easier to design and more convenient for separate wavelength monitoring. Picture below can be the reference for single-fiber unidirectional transmission.

DWDM Mux/Demux

Single-fiber bi-directional is used to transmit and receive optical signals in two directions at the same time in an optical fiber, just like the positive and negative lanes separated by the separation belt on the road. Vehicles on both sides of the road run in their own lanes without interfering with each other. The advantages are also obvious. Single fiber bidirectional technology can use only one fiber to complete the work that two fibers can do, the existing fiber transmission capacity has been doubled, thus greatly saving fiber resources. Picture below can be the reference for single-fiber bi-directional transmission.

DWDM Mux/Demux

Dual-fiber DWDM Mux/Demux uses two optical fibers, one of which only transmits the optical signal in one direction, while the other transmits the optical signal in the other direction. The advantage is that dual-fiber DWDM Mux/Demux requires two fibers for transmission, each signal is carried by different wavelengths and will not affect each other, the reliability would be higher.

DWDM Mux/Demux

Channel Port

Like line port, channel port is another important port. A DWDM Mux/Demux usually has several channel ports on different wavelengths and each channel port works for a specific wavelength. The channel port of a DWDM Mux Demux is usually ranging from 4 to 96, using the wavelength ranging from 1470nm to 1625nm with a channel spacing of 0.8nm (100GHz) or 0.4nm (50GHz). A DWDM Mux/Demux with more channels offers more capacity, yet the price would be higher as well.

Monitoring Port

Except for the must-have line port and channel port, DWDM Mux/Demux can also be added with other ports such as monitoring port for better network monitoring and management. The monitoring port offers flexible monitoring ways to test the power, wavelength and optical-signal-to-noise ratio (OSNR) of the optical signal without service interruption. Besides, early warning can be provided in time if there is any deviation. Therefore, it can also improve the stability of system transmission. The monitoring port can be either a simplex or duplex fiber port, which depends on the type of DWDM Mux/Demux you are using. The simplex fiber port can monitor only the DWDM, while the duplex fiber port can monitor the entire network.

Active/Passive DWDM Mux/Demux

DWDM Mux/Demux can be divided into active DWDM Mux/Demux and passive DWDM Mux/Demux according to whether the device needs power supply or not. Active DWDM Mux/Demux indicates the device needs power supply.

An active DWDM Mux/Demux includes wavelength adjustable laser, wavelength adjustable filter and wavelength selective amplifier, etc. Active setups grant you more control over your optical network, you can dynamically re-tune wavelengths without dropping connections. Active DWDM Mux/Demuxs are widely used in large capacity optical transmission applications.

“Passive” indicates the DWDM Mux/Demux is an unpowered, pure optical equipment. It requires zero maintenance, upgrades, or electricity to function properly. A passive DWDM Mux/Demux includes dispersion device, interference device, optical coupler and so on. Passive DWDM Mux/Demux is a plug and play system, which is simple and convenient to use. It is mainly applied to the access layer of MAN, campus network, enterprise network and various special industry networks (such as banking, public security, etc.). At present, passive DWDM Mux/Demux is widely used in optical fiber communication solutions.

However, passive DWDM Mux/Demux does not have the OAM function, and does not have protection means in case of link failure. To solve this problem, another type of DWDM Mux/Demux has been developed by FS. Based on the passive DWDM Mux/Demux, it adds optical switches, optical splitters and other devices in optical fiber link. This DWDM Mux/Demux device needs to be connected to the power supply by default, when the power is on, it can be used as an active DWDM Mux/Demux to monitor each port in real time; when the power is off, the device can still be used as a passive DWDM Mux/Demux without affecting the link transmission. It combines the advantages of active and passive DWDM Mux/Demuxs, and effectively solves the shortcoming of passive DWDM Mux/Demux which cannot be managed and maintained through the intervention of active equipment. Therefore, it is now becoming a more popular deployment choice in networking solutions.

Packaging Types

DWDM Mux/Demux come in three different packaging forms – 1U 19″ rack-mounted, FMU plug-in and splice/pigtailed ABS box. The first type is in 19″ rack-mounted package, easy for installation. The second one can be used with 19″ rack chassis, which is very convenient for use by just plugging in. The last one is in ABS box package based on standard thin film filter (TFF) technology and its pigtails are labeled with wavelengths. It takes little space and can be installed in various chassis. Pictures below can show more details.

 three different packaging forms


To improve the efficiency of network transmission, DWDM technology is often deployed in the devices. DWDM Mux/Demux is now recommended as one of the most cost-effective network solutions with expanded fiber capabilities. Hope the above explanation on its working principles and the analysis of different factors can help you make the best choice on the DWDM Mux/Demux for your network.

How to Choose a Network Interface Card?

Network interface cards, which are also called NIC cards or fiber LAN cards. Nowadays, there are a variety of network interface cards in the market. Various network interface cards differ in transmission rate, prices and other aspects. And using different network interface cards may get different network performance. So how to choose different network interface cards is important. This post will give you some tips on choosing network interface card, which is likely to help you to choose the most suitable one.

Types of Network Interface Card

According to the bus interface type of the network card, it can be generally divided into ISA interface network cards, PCI interface network cards, PCI-X bus interface network cards and PCIe network cards. Based on different interface, it can be grouped into Ethernet RJ-45 interface network cards, BNC interface network cards, AUI interface network card, FDDI interface network cards and ATM interface network cards. In terms of transmission speed, there are gigabit network cards, 10G fiber network cards, 25G fiber network cards and 40G fiber network cards. As you can see, there are many types of network interface card. So how can we choose different types of network interface card, some tips will be given in the following part.

Tips on Choosing Suitable Network Interface Card

In the following part, some useful suggestions about selecting different types of network interface cards will be elaborated in detail.

Checking Supported Connector Types

Due to different network transmission media, common network interface cards have three different connector types. some network interface cards provide two ports on one card at the same time, and some network interface cards also provide three ports on the card at the same time. These ports are AUI port, BNC port and RJ-45 port. The AUI connector is often used with the thick coaxial cable, the BNC connector IS often used with thin coaxial cable and the RJ-45 port connector is often used with the unshielded twisted pair. Many small local area networks use a thin coaxial cable and a bus network with a BNC connector. The cost of this connector is low, but it is not easy to manage, especially for a large local area network. So you need to choose different types of network interfaces card according to different supported connectors.

Determining the Transmission Rate

Take Ethernet network cards for example, there are 10Mbps, 10/100Mbps, 1000Mbps, even 10Gbps network interface cards in the market. In general, people is more likely to think that the network interface cards which have higher transmission rate will be the better network card. but it is not true. For example, if you insert a 1000Mbps card network card into your computer which connected with the 100Mbps twisted pair, the maximum transmission rate can only reach 100Mbps, so it is a waste to use this type of network interface card. In order to avoid unnecessary waste, you need to be careful when selecting network interfaces with different transmission rate.

Considering Prices and Brands

The prices of network interface cards in different brands is various. But there are some well-known brands, such as Intel, Netgear, Mellanox, FSand so on. Those brands are popular in customers because their products have good quality and perfect network performance, which is more likely to meet your requirements for network interface cards. Since the prices of different interface cards are effected by many factors, such as transmission rate, different ports and so on. When you comparing different network interface cards, you should not only consider the prices, but also you need to take each parameter of network cards in different companies into consideration, then make a wise choice.

Paying Attention to the Bus Type

PCI, PCI-X or PCI-E bus intelligent card are commonly used by servers and workstations. And the ISA connector is no longer support the PC. So when you purchase network card for you PC, what you should choose is the PCI-X and PCI-E or PCI card instead of the outdated ISA network card. And the PCIe network interface cards are now widely used in the customers. Here gives several types of PCI-E network cards in FS. Just show as the below picture.

10G base-T, network interface card

Figure1: Different types of 10G  PCI-E network cards in FS

Compatibility of Operating System

If you want to buy a network interface card, you need to consider which network interface can support your operating system. In general, most network interface cards can support Microsoft® Windows®, but not every interface card will support Linux or Apple’s Mac OS X. So you need to make sure that the network interface is compatible with the operating system that you are using.


As is known to all, the performance of network interface card can greatly affects the network performance and the data transfer rate of overall network. With the tips mentioned above, we hope this post can give you some inspirations in choosing the proper network interface cards. If you need any help, feel free to contact us at sales@fs.com.

The first and foremost element to consider is the performance level. To effectively increase bandwidth speed, it is recommended to play Cat5e bulk cables with Cat5e plugs, Cat6 bulk cables with Cat6 RJ45 plugs, and cable Cat6a with Cat6a RJ45 plugs, say, match two components with the same performance level.

Conductor Gauges Supported

Conductor gauge refers to the size of the conductor cross section. It goes oppositely from the diameter, as the larger the figure is, the thicker the conductor looks. When punch down bulk Ethernet cables, the eight conductors should cling to the 8 contacts in the standardized order and they should be identical in gauge size. 23 AWG, 24 AWG and 26 AWG are supported by FS RJ45 connectors/plugs.

Cable Construction

According to cable construction, the network cable can be classified into stranded cable and solid cable, which is correlated with the contacts in the plugs. The first contact shown in the picture has the contact prongs that straddle the conductor, suitable for both solid and stranded cables. The second one suits only the solid cable as the jagged end pierces jacket and embeds into the strands of the conductor. The third one adopted by FS is applicable to both solid and stranded cables. Its long contact prongs spread apart to accept the conductor, ensuring the connectivity and reliability.

Shielded Vs. Unshielded RJ45 Connector/Plug

Shielded plugs are more expensive than unshielded ones, as shielded plugs have a metal outer shell and are often specified in areas where a shield or ground connection is required. Areas with high electrical noise use shielded cable and plugs.

What Is the Boot Cover?

Boot cover is a cable device that protects the connector from bulk cable snags while providing strain relief. It is slid over the RJ45 connector. An advantage of an RJ45 strain relief boot cover is that it completely closes the connection between the connector and the connection. This means that dust can not be added and the chance of malfunctions is reduced. One should first make the boot on the cable and then attach the connector. When you do this in reverse order, the connector can not be put over it anymore.

Things to Consider When Buying Boot Cover for Cat5e, Cat6 and Cat6a Bulk Cables

Cable Diameter

The diameter of the cover’s inner circle cannot be smaller than the cable diameter. Otherwise, the boot cover cannot be slid into the cable. FS provides different sizes of boot cover for bulk Ethernet cables: 5.8mm, 6mm, 6.5mm, 7mm and so on.

Cable Construction

Compared with solid cables which only contain one conductor, stranded cables that consists of several conductors woven together are more flexible. The boot covers for the two types of network cables are different. FS specifies them according to the cable construction for the customers.

Shielded Vs. UnShielded

Shielded bulk cable has an additional shielding jacket around the conductors, so it is thicker than the unshielded one. You must make clear the type of your network cables before buying the boot cover, to avoid unnecessary cost waste caused by improper selection. FS provides boot covers designed specially for the shielded bulk cable.

Structured Fiber Cabling Solutions for Network & Server Cabinet

How does your network or server cabinet look like? Are they stocked with varied servers or networking equipment connected with long cables that reach out to the devices on the other cabinet or enclosure? This is exactly what we used to call point-to-point cabling. However, it is also an art to keep a neat cabling. This article unveils a compelling new cabling method—structured fiber cabling solutions for network&server cabinet.

What Is Structured Cabling and How Does It Matter?

In recent years it has become apparent that fiber-optics are replacing copper wire as an appropriate means of communication signal transmission. The standardized architecture and components for communications cabling formulated by the EIA/TIA TR42 committee—structured cabling is used as a voluntary standard by manufacturers to ensure fiber-optics interoperability. In a structured cabling system, a variety of patch panels and trunk cables are harnessed to create a structure that allows for hardware ports to be connected to a patch panel at the top of the server rack. That patch panel is then connected to another patch panel via a trunk (multi-fiber assembly designed for use in conveyance) in the MDA (Main Distribution Area). When you have several servers, with multiple patch connections and power cords running through your server rack, you need to keep them arranged and managed with an excellent rack cable management system.

Here some may wonder why bother to cost more on the connecting gadgets? Well, without running long patch cords from equipment racks, MACs are much quicker as the cable and port tracing becomes a much easier job. The potential for downtime goes down with the reduced potential for human error. A structured cabling system will look aesthetically pleasing.

Structured Fiber Cabling Solutions for Network & Server Cabinet

In the server room, there may be a server cabinet and a network cabinet for the storage of routers, patch panels, switches and a wide variety of networking equipment as well as networking accessories. Taking FS GR600-series server cabinet and GR800-series network & server cabinet housing 10G and 40G applications as an example, let’s see an exemplary structured fiber optic cabling.

What Is Open Networking and How Does It Benefit Customers?

Open networking possesses distinct interpretations in different fields. It gradually picked up steam when adopted in open network switching, attracting flocks of vendors to take a share from the giant and burgeoning market. What is open networking? This article facilitates us to have a close look at it.

What Is Open Networking?

Open networking appeals to breaking the tight linkage between the hardware and software. Previously, network switches are sold with hardware and software together. That is to say, if users buy a Juniper EX or MX series network switches, they also buy JUNOS; if customers buy a Cisco Catalyst network switch, they have to buy Cisco IOS. With the advent of open networking, things vary greatly alongside the separation of proprietary hardware from its software. Ethernet switch now lives in a disaggregated world where these elements can be chosen from the most appropriate supplier. Not only hardware and software, but also technical support and accessories are traded respectively.

How Does Open Networking Impact on Network Switch?

Open network switching hardware was first adopted by tech giants such as Google and Facebook, followed by a slew of enterprises. Besides, Cisco is jumping on the bandwagon of disaggregation in data center networks. It will allow data center customers to run its Nexus operating system (NX-OS) on third-party switches and to use other network operating system on its Nexus switches. Having been backed by several hyperscale companies, open networking drives the network switch to develop in a decentralized way.

How Can Network Users Benefit From Open Networking?


Open network vs. closed network, flexibility wins. As it is stated elsewhere, open means choices and options. You can configure the devices with equipment, software and architecture designs from different vendors. And you can turn down the affiliated OSes that may be feature-rich for you, and refer to those satisfying your rigid demand. Open networking entitles you to the architectural freedom to deploy the best topology and protocols for your environment. This has also fostered innovation dramatically with technologies and practices, allows enterprises to move faster to capture opportunity in the market.


With open networking, you can save budget on dealing with what breaks down rather than throwing away the malfunctioned network switch. That is to say, if open source hardware fails, then you can change it; if software can no longer satisfy your needs, then replace it with other open source software. For example, some people have encountered the issue that the switch whines loudly. In this case, you can decide to make changes only on the hardware. Targeted troubleshooting also saves time and energy.

Unified Development

From the perspective of the vendor, they can jump out of the scenario where they work behind closed doors, and turn to seek common points while reserving difference from others. You want to survive in the market, you need to be open, inclusive and be compatible to the third parties gadgets. A closed system by definition prevents others from openly interfacing with your offer, thus stifling collaboration and increasing the time to market. FS.COM not only released the open networking switch, but also recently sought cooperation with Cumulus Networks to add the leading open source operating system—Cumulus Linux to the FS N-series 40G and 100Gbe switches. This progress brings high-end features like automation to customers.
