Facing Hub-Networking Problems? Go For Switches

In modern times network communication is an intrinsic part of any business setup. However, in setting up a hub based network connection many problems arise that seem to grow with the growth of the networking setup. Basically there are four different types of problems that arise. The Problems 1. Scalability – this is the first problem that arises in a network that uses hubs. In hubs the problem exists of choosing growth over performance. As the bandwidth is limited it is shared between the computers and so there is no significant growth. Today’s network hungry applications need more bandwidth than provided and so sometimes the whole network setup has to redesigned to allow for growth. 2. Latency – this is another problem that bothers network setups that have hubs instead of switches. Latency can be simply defined as the amount of time that is needed by the packets of data to reach their destinations. In a hub connected network, the problem is that one node has to wait for a time before it can send its data to the destination. This increases the latency period. Moreover, transferring large files can also take up a chunk of the bandwidth pie and so will result in slower movement of data. This actually happens to avoid collisions. 3. Failure of network – a hub does not have the settings required to configure the speeds between devices. If the speed settings are different than what they should be the problem of network failures arise. 4. Collisions – this occurs when two computers in a hub-network send data packets at the same time and those data packets collide with each other. The situation worsens when there are more computers or nodes connected and each attempt to send data packets. The part of the network where a chance exists for a collision is called as collision domain. The Solution To avoid the problems that a hub network faces, switches are used. A switch is basically a device that allows computers to connect with each other. But it has certain advancements over a hub as it overcomes the problems. The areas where a switch overcomes the problems are: 1. Allowing full bandwidth – a switch allows full bandwidth to all of its linked computers and so the computers do not have to share the bandwidth. This results in proper utilization of bandwidth resources and applications that require more network speed can work fine. 2. Ability to configure – a switch has the ability to configure the ways to check and limit the broadcast limits for each of its connected computers. 3. Avoiding collisions – to avoid collisions switches have a system of CSMA/CD which is present in Ethernet connectivity. Unless a line is clear a computer will not send out data packets to another computer. This helps avoid collision and no data packets are lost. To get the best out of networking switches should always be preferred over hubs. In data centric businesses the WS-C3560G-24TS-S or the WS-C3560V2-48PS-S are good quality switches that provide superior quality networking solutions.

What Are The Data Storage Problems?

Storage for data needs is a growing concern and small and medium scale businesses in data centric businesses face this problem. As companies grow the need to store huge amounts of data grows too. This can be viewed as the price a business has to pay for growth. The problem of data storage is persistent and never ending. However, one of the ways is to be alert to the needs and scale the availability of storage.

Data Storage – Real Problems

As businesses have grown so has grown the amount of data storage. When we check the real figures we are astounded by the sheer size of them. For example, the retail giant Walmart does transactions on a day to day basis. The size of their database is a whopping 2.5 petabytes. The social networking leader Facebook has in its database about 40 billion images and photos. And, more is following. It has been reported that since 2011 the amount of information generated will be doubled.

Duplicate Data

This is one of the real problems faced by businesses. This deals with the fact that there are multiple entries for a single customer/product and that can lead to the wastage of valuable storage space. It also prevents easy retrieval of data and slows down data processing. Businesses should be wise to avoid this kind of problem and focus on an initiative to get rid of duplicate data to save energy and costs. However, historical data should never be deleted or cleansed to make way for new as this could prove to be disastrous.

Virtualization

Many businesses are now embracing virtualization as they see the benefits of it. However, with virtualization comes the problem of storage, pattern of data flowing, security etc. Proper knowledge about the mode of interaction between servers and virtual machines is essential to reduce the problem.

Backing up Problems

Nowadays, almost all the businesses are spending a good amount of money on data backups. They have realized that the backup data which seems useless today might one day save their businesses. Obviously it takes some time to back up data including those that may not have been touched for quite a period. To solve this, file virtualization is employed which backs up changed data more frequently than that which has not been touched for a while.

Lastly

As businesses do better their need for data storage grows too. It is essential in this regard that the growth can be managed in a systematic way so as not get carried away with unnecessary demands for storage solutions. Here is where capacity management and cost accounting comes to play. Moreover, the issue of low storage of data should not be addressed as merely a hardware issue.

For ultimate storage solutions many businesses nowadays rely on the StorageWorks EVA 4400 or the HP D2700. Both are manufactured by HP and are very good data storage solutions.

What Are The Common Network Cable Types?

In this modern of wireless connectivity using cables seems like old fashioned. However, majority of computers are still connected via cables. The cables or the network cables as they are called are unlike normal electrical wirings and they are of mainly 3 types. These types of cables have evolved and are mainly used in LAN connections.

The three types of cables are: A. Coaxial Cables – these cables are similar looking to those that TV wires. A solid copper wire sheathed with insulation is present in the core. A braided wire and metallic foil covers the insulation from any sort of electromagnetic interference. Lastly, there is a layer of insulation that covers the wire coating. Coaxial cables are of two types: 1. Thinnet – used for short distance cabling it connects directly to the computer. Only ¼ inch thick, the maximum length of this cable can be 185 m. 2. Thicknet – about ½ inch thick, this cable can be about 500 m in length. This has the ability to transfer data for longer distances and is used as backbone cabling. B. Twisted Pair Cable – a pair of wires is used to form data transmitting circuit. The twisting is done to reduce the negative impacts of crosstalk and noise generation. In this type of wire, the signals are sent in opposite directions so that the magnetic field that is created cancels out. Two types of fiber cable exist. They are: 1. Unshielded twisted pair – made up of four pairs of copper wiring sheathed in different colored plastic. In addition to this there is a plastic outer jacket for extra protection. These cables have small diameters and do not need grounding and are the most common. There are many different types of UTP cables and the most common are Cat 5, Cat 5e and Cat 6. 2. Shielded twisted pair – this is a pair of copper wires that are covered with insulations that gives an extra protection from electromagnetic interference. This is commonly used in Ethernet networks. C. Optical Fibers – these carry signals in the form of light impulses. The cables are made up of a very thin glass core and concentric layers of glass cladding. One of the fibers transmits light while the other one receives light. The types of optical fibers: 1. Single mode fiber – transmission is carried over long distances with a single ray of light.

2. Multi mode fibers – multiple rays of light run at different angles and carry the transmission. These are the types of cabling that are used for data transmission. Among them, optical fibers are the best form of transmission but they are expensive too. For switching needs in LAN based connections the WS-X6716-10G-3C and the WS-C2960S-48TS-L are very good.

Concepts Related To Networking – General Terms

A network switch is a device that connects different network connection points to get in touch with one another. Switches are extremely useful as they speed things up and help connect in a smooth and effective way.

A LAN switch connects two devices that are to communicate with each other at any one particular time. To understand the working of networking we need to clear out a few of the facts associated with networking:

A network can be defined as a set of computers to allow information to be sent back and forth between them.

A node can be defined as any electronic device that is connected to a network. A node may consist of not only a computer but also a printer or any other peripheral devices.

When a switch or a bridge separates a portion of a network from other parts of the network, a segment is formed.

The main cabling that connects all the segments together and transmits information between them is called the backbone. Since, the main cabling carries more information it is imperative that the speed of it should be more than the individual segments.

The way a node (computer or other devices) is connected physically in a network is called as topology.

A set of computers present in more or less the same physical location and connected through a network is called a LAN. This is generally present in an office building.

A Network Interface Card connects computers (for desktop computers this is an Ethernet card) with the network.

The MAC address or the Media Access Control address is a 6 byte long address that identifies the computer on the network. The first of the parts identifies the company which made the NIC and the rest identifies the NIC itself. In other words the MAC address is the physical address of the computer.

A mode of transmission where one node is specifically addressed by another is called as unicast mode of transmission.

When a node transmits to a special group address, that method of transmission is called as multicast mode of transmission. A device will only be able to receive data if and only if, it is authorized to receive information.

Broadcasting is the mode of transmission when data is sent out by a node to all other nodes to which they are all connected.

These are some of the terms that are connected with the concept of networking. Switches are a very essential part of the networking architecture. The WS-X6716-10G-3C and the WS-C2960S-48TS-L are very good switches that possess genuinely good qualities.

A Few Tips before Buying Server Racks

A server rack is an enclosure that is used to house key components like server machines, kvm switches, monitors, network equipment etc. This is used for vertically storing the equipments that need to be kept in that position. It would be a folly to look at them as just another piece of shelving equipment as a good server rack will always provide good security and ease of management network.

These racks can be found in various sizes and shapes but the standard size is 19 inch. Other things are sometimes attached to server racks as accessories like fans, power strips etc.

There are a lot of features, advantages and important points to consider before one considers a server rack:

The first thing to consider is the needs of a company – the equipment to be installed, the number of equipment pieces to be housed, the power requirement etc. A good understanding of the requirements will enable one to find the right one.

One important aspect to consider about server racks is that they should be of the right dimensions. There are wall-mounted, desktop or standing racks and the one that is chosen should be based on its usability. The dimensions and the type of the racks should be dependent upon the work area and the network equipment load.

Depending upon the need for the equipment to be connected, the server rack should be bought. Moreover, there are accessories that help customize the server rack.

Regarding security, there are server racks that can be barely simplistic (least secured) or fitted with 4 sided panels and multiple locking systems. They may be fitted with smoke screened locking doors that provide good visibility or fitted with removable locked side panels that provide access to equipments as and when necessary. The choice of security will depend upon the level of threat one has to face in keeping the server machines not prone to attacks.

Next comes the point of whether the rack is assembled or to be fitted and also the build material of the rack – steel or aluminum.

The accessories of the server racks can be from fixed or rollout shelves, keyboard trays, power strips, blanking panels, cables etc.

The final words lie in the ability to understand the needs of an organization and the best possible server rack that can be bought. It should depend upon the security, configuration etc and not be influenced by deals being thrown.

There are many other considerations that need to be cleared about before getting a server rack. Some thought must be spent on this equipment though the contents that it will house are more important. Among good rack servers the PowerEdge C6100 is a good product from Dell. Other than servers, if one considers host bus adapters, then the QLE2560-CK may be considered.
