What is Network Storage? (Introduction)

 

 

Before directly navigating towards knowing What is Network Storage, let’s see how network storage is invented. As you know we were lucky enough to witness the rise of technology. Multimedia technology is one of them which enjoyed unimaginable rise. We have seen tremendous change in multimedia technology, let us consider an example of mobile multimedia technology that requires a sort of local storage device, in the form of a memory card to store multimedia files.

Storage devices are requiring to store objects such as text, image, video, audio, etc. Traditional storage devices include pen drives, hard drives, SSD any many more. They are heavily used in today’s Personal computers, Laptops, Mobiles phones but they are having two most important problems associated with them, these are

  1. Sharing is not possible
  2. Cannot Scalable

We have used a Nokia3310 up to today’s latest android and iPhone mobile handsets. If we compare the image size of the Nokia 6600 and the latest mobile phones then we observe that image size increases about 5 times as the camera megapixel increases. The same case happens in the term of size of the video. Latest video technologies include 4K resolution, increased frame rate, 3D/5D/7D immersion and thus it requires tremendous local storage memory of about several hundred MB for about 1 min of video. Overall the memory requirement of individual users increases at ultra-high speed and to cope up with this speed one requires a very huge amount of external storage.

New solutions such as external drives were very famous among users which overcome the problem but this strategy again began to inefficient as user method began to change. Nowadays user is multi-device and globally roaming thus external storage method strategy will not be enough and useful. Also, this is a very costly solution and not feasible too.

To tackle this problem researchers and engineers have coined the new term that is network storage technology. It’s a type of virtual memory and can be accessed through an internet connection irrespective of device, irrespective of location.

What is Network Storage? (Technically Concept)

 

Network storage is simply virtual storage but seems like physical storage that we are going to use. The storage devices are remotely placed and can be accessed with the help of internet thus network connectivity is most important here while considering this type of storages. It removes storage limitation and availability problems which are worth of concern in terms of physical storage devices

Network storage is a very important aspect while considering the individual or business sector. Due to proper storage management techniques, the small-scale industries can concentrate on their improvement of server performance & availability of their web applications. Today we are having multiple flavors of network storage technologies, some of which are Cloud, NAS, and SAN, etc. We will see each of these in brief and will head towards block storage.

Types of Network Storage

 

 

1. Cloud Storage

 

 

Cloud storages are very popular nowadays. Here the user data is transmitted and stored at remote storage devices which may be in the form of multiple servers and multiple locations too with the help of the internet. This data is in the form of a logical pool called “the cloud” which is further managed for maintenance and backups. It is made available to end-user as per their requirement. Some cloud services are paid while some services are free to the user. The best example of cloud service is Google Drive, Dropbox, iCloud, Microsoft One Drive and other dozens of cloud storage providers.

There are a lot of benefits we can enjoy while using cloud storage but there are also some areas that require our attention. While enjoying several benefits such as Usability and accessibility, Cost-efficiency, Synchronization, Scalability, Disaster recovery etc. we shouldn’t neglect the most critical issues such as Internet dependency, Data security, and privacy, the Expensive cloud storages.

Thus, it’s your decision whether to go to the cloud or not??

2. NAS (Network Attached Storage)

 

 

NAS Storage

If you are not happy with the risk of security which is the most critical parameter in cloud storage, then you can have NAS which gives a little confidence regarding your security-related doubts.

Technically speaking NAS is a type of external drive but which is mounted itself on a local area network such as Ethernet or Wi-Fi. What is the most important thing is that the NAS should be always connected to the internet. Once it active on the network anyone can access it like a local hard drive. The data on NAS can be accessed as “files”

You can access NAS remotely by proper configuring your local area network, without any risk of security but again it has a limitation of maximum capacity.We can have one option to solve this problem that is we have to create a series of NAS to increase the capacity but again this is not a feasible solution because each NAS must be controlled separately and it’s a bit complex and difficult.

3. SAN (Storage Area Network)

 

 

As discussed earlier problems related to NAS can be tackled with SAN. SAN is a network of interconnected storage devices that can be accessed with the help of internet connectivity. We can compare SAN with disk server. SAN is preferred mostly by Developers, Data centers, Businesses, large establishments, etc. In SAN the data is accessed in the form of “blocks” therefore sometimes referred to as block-level storage. Nowadays NAS is synonymously called block storage. They require different protocols instead of TCP/IP such as Fiber Channel and iSCSI (Internet Small Computer System Interface

Benefits of SAN:

 

 

  1. As it is a group of storage devices thus there is not any limitation on capacity. We can add multiple storage devices as per our requirement. A storage pool can provide limitless access to the resources being used.
  2.  The most important benefits of SAN are Data backups this is very useful in disaster recovery.
  3. Synchronization is also one of the great benefits SAN gives.We can have the facility to automate the synchronization as per our required time frame. It takes care that no single piece of data remains unhandled

Block Storage Server (SAN)

 

 

We can use the block storage method as an alternative to the file storage method block storage method is also known as block-level storage, is a fixed-sized, row storage method that is reliable, fast, efficient, and redundant. Here the data is being chopped into smaller pieces called “blocks”, which are then assigned a unique number for proper identification required for retrieving data. All the blocks are of the same size and each one is having a unique identifier. As the files are braked into different pieces they lost their original meaning and therefore cannot be readable or able to execute.

Here in block storage data is considered as the raw piece and each piece is considered as a separate individual hard drive thus we can use it for any purpose such as database, virtual machine file storage.

Block storages mostly suitable for container technologies. File system storage operates data into files and folders but here chunk of data is stored in the form blocks. They are generally used to take snapshots which is backup taken at different specific point in time.

What is Virtualization? What are the benefits of using Virtualization?

What is Virtualization

What is Virtualization?

Suppose there is a number of applications to be performed to run your business and eventually it will require the same number of servers i.e. one server for one application. This is the simplest strategy one can consider while designing IT infrastructure, but it will be costliest that is it will increase the operating cost of business also It will not utilize available recourses properly.

The solution to this problem is virtualization. If you are the guy from the technology industry then you must have been heard about multiplexing. It’s simply nothing but sharing single communication media between multiple users. You can apply the same analogy to virtualization, here physical hardware is shared among the various operating system or applications and gives them a look of an independent entity.

What is Virtualization – Explained

The main component which separates the single physical hardware among various virtual machines is called a hypervisor.it is a type of operating system and software, which operates on physical hardware. It dynamically allocates available physical resources to virtual machines to be created.

What are the benefits of using Virtualization?

There are multiple advantages of a virtualization, out of which important ones are

  1. Infrastructure cost reduced to a great extent
  2. Energy efficient
  3. Enhance the productivity of the system
  4. Enable remote login

What are types of Virtualization?

The concept of Virtualization can be further extended to Server, Application, Memory, Storage and networking virtualization.

1. Server Virtualization

The most common type which generally considered virtualization is server virtualization. It is nothing but running multiple operating systems on a single physical hardware and most important is they are running independently. As the resources are shared among different OS the proper utilization of resources takes place. Each separate O.S. is also pronounced as guests, instances, or containers.

2. Desktop Virtualization

In this type of virtualization, multiple user desktop instances are created on a single host. Users are having the facility to access these desktop instances remotely. The best example of desktop virtualization is N-computing.

3. Application Virtualization

Here the application to be virtualized is installed on a host and can be used by multiple number of users remotely. The WINE is the example of software which is used for application virtualization. It allows UNIX based operating systems to run Microsoft Windows based software directly on host. With the help of application virtualization, the application data is synchronized with main server and can available anytime to the user.

4. Application Virtualization

It is nothing but pool of different physical storage units. It is managed by a software generally by hypervisor. it provides scalability, redundancy, improved performance. Due to storage virtualization the problem of limited storage can be resolved because one can add memory quickly into a pool. The storage virtualization can be further classified as

Block Virtualization

File Virtualization

5. Network Virtualization

It combines number of physical networks into a virtual single network or vice-versa. This new virtual network is software managed network.

The best example of network virtualization is to create virtual LAN. It is logical to a group of computers. They are appearing to be on the same LAN but they are virtually created. The advantage of network virtualization is that the network admin can automate the networking task and no need to control it manually. Also, it is very easy to scale the network according to requirements. Some of the advantages of network virtualization are

  1. It reduces the cost of hardware purchase
  2. Faster application delivery
  3. Improved security
  4. Centralized control
  5. Scalable network

What is Hypervisor? What are the types of Hypervisor?

It is software that is responsible to create and control virtual machines. Currently, there is a number of hypervisors which are available in the market, some of the famous examples are, Oracle Virtual Box (Apple, Linux, Microsoft), Microsoft Virtual PC 2007 (Microsoft), Parallels (Apple), Microsoft Hyper–V (Microsoft), VMware (Apple, Linux, Microsoft), Citrix (Apple, Linux, Microsoft), Linux VServer (Linux).

What are the types of Hypervisor?

Hypervisors are mainly categorized according to their placement into the system. Generally, there are two types of hypervisors are there which are

Types of Hypervisor
Types of Hypervisor

Type 1 (native) hypervisor:

In this type of hypervisor, then it is installed directly onto hardware without being managed by the operating system into the middle. They are also known as bare-metal types of hypervisors. As it is having direct access to the hardware is faster than the next type of hypervisor that we will be going to discuss soon. It’s more secure and scalable too.

VMware ESX and ESXi, Microsoft Hyper-V, Citrix XenServer, Oracle VM are some examples of type 1 hypervisor.

Type 2 (hosted) hypervisor:

here the hypervisor is not installed directly onto hardware rather there is an operating system between hardware and hypervisor which controls the hypervisor. it uses the O.S. virtualization technique. As the operating system controls the hypervisor that’s why it is somewhat slower than type1 hypervisors. Scalability is also somewhat limited as compared with the previous type. It is less secure too.

VMware Workstation/Fusion/Player, VMware Server, Microsoft Virtual PC are some examples of type 1 hypervisor.

KVM As a Hypervisor

Kernel-based Virtual Machine is the Linux-based type-1 hypervisor. It supports native virtualization on the processor. Technically speaking it’s not a perfect type 1 neither type2, it’s somewhat middle between them. some of the key benefits are consist of loadable kernel modules.

  1. It is very secure due to SELinux and sVirt library.
  2. Gives near-native performance.
  3. KVM is also full virtualization technology thus no modification is required into the guest operating system.
  4. It also supports memory virtualization capabilities therefore all types of memory access mechanisms are supported
  5. Most of all It is open source and thus free to use

What is GPU Server? Uses & Benefits of having GPU

Dedicated GPU Server

What is GPU Server? Uses & Benefits of GPU

          People who are not tech savvy they feel like they have heard something wrong word, but you have heard correct word and it’s not CPU rather its GPU. Let me first tell you that GPU stands for Graphic Processing Unit. In simple words, GPUs look just like another chip, but inside, there is an array of dozens, hundreds or thousands of small computing units (or “GPU Cores”) that work in parallel, and this is the main reason for why GPUs are so much faster than CPUs to compute images. In GPU hundreds of small computing cores get the job done faster than a handful of big cores.

What is the difference between CPU and GPU?

         All of us know that CPU is central Processing Unit, but I strongly feel that it should be General Processing unit, because CPU does all the thing which are required for working of your Computer, Laptopo any other gadget.

        The main difference between CPU and GPU is their purpose, the CPU mainly designed to carry out general calculation as I said, and GPU is solely designed for graphic and video rendering purposes. More precisely here we can say GPU is a co-processor that helps CPU.

        Here again question arises, that why one should require separate GPU for graphics and all that??The answer is that graphical images and video processing requires too many things to do such as pre-rendering the files, making the files, compressing it, storing it, modifying it. etc. if all the processes are carried out by CPU then system performance will be degraded

       Very badly and to avoid this GPU will carry this compute-intensive works by itself and helps CPU to work fast

CPU Cores vs GPU Cores

CPU Cores vs GPU Cores

        Generally, CPU is having up to 8 cores but GPU is having hundreds of cores. Another difference is that CPU works linearly i.e. serially we can say, but GPU works parallelly. The highly compute-intense data will be crunched into parts and all the parts are computed parallelly into the GPU and that’s why GPU makes faster calculations.

Is graphic card and GPU being same?

        No… Not at all. Simply graphic card is hardware as a whole and GPU is one of the major parts of a graphic card. Sometimes GPU is integrated into the motherboard.

Do I really need GPU?

       This question is somewhat tricky because every computer or laptop or some other device has some sort of GPU. It’s not like some of the devices are not having GPU at all…. because without GPU it’s difficult to display an image. so, rather than saying that do I need a GPU we can ask Do I need a dedicated GPU???

       It depends on you. Our general-purpose applications such e-mails, word processing, listening music even watching HD like videos really don’t need any GPU. in a nutshell If one who does not have to deal with graphic and all that stuff then there is not any need of GPU, 

       GPU is mainly required for playing high graphic games like Asphalt 8: Airborne, Modern Combat 5, Player Unknown’s Battlegrounds (PUBG), Need for Speed – Most Wanted etc.

       GPU can be beneficial to non-gamers too such as if you do intense photoshop designs if you do intense 3D art design, intense video editing.

       One of the most important uses of GPU is to connect multiple displays at the same time. In today’s multimedia world it’s been necessary for video editors or gamers or YouTube creators to use multiple displays which is somewhat limited due to fewer HDMI or DVI ports provided by CPU but GPU can provide you multiple numbers of the port for your multi-screen experience

If GPU is such fast then why should not we replace the CPU with GPU?

       Again, it is tricky while answering this question. Can you compare Fish with an Eagle??? Certainly not because they are having totally different types of ability thus we can’t compare them. The same is applicable to this question. Actually, the CPU is made to handle general-purpose activities while GPU is solely for graphic rendering.

Differences between various hosting services

Which Shared Hosting is Good For me?

Differences between various hosting services

Hosting Service

Hosting technology makes a tremendous change in the IT industry and it bursts the data over the internet. Trust me guys, hosting is very old technology but just in new packaging. During the industrial revolution, OEM was and’s still very famous and hosting is a sort of OEM. Business textbooks often refer to OEMs as “contract manufacturers.” Hosting is the same concept where the hosting provider company acts as OEM and our application as VAR.

The two share a mutually beneficial relationship, as VARs help OEMs sell their products and OEMs entrust their products to VARs, allowing them to sell them with more features that will enhance the operation of the products.

keeping in mind about new website product whenever we search for hosting services providers then we come across multiple dozens of provider each having their own specialty and their own way of providing service with multiple platforms at this time its cumbersome to choose a right provider which will be beneficial to us in all possible ways. before going to choose the right provider one should have a thorough knowledge of what kind of hosting we want.

We can have to host with so many flavors, among which we can classify them into mainly these below-mentioned categories,

Full-featured hosting services

Shared Hosting

Virtual Private Server (VPS)

Cloud Hosting

Dedicated Hosting Service

Shared Hosting

In Linux Shared Hosting single server is shared among the users, here no dedicated or virtually dedicated server is available to the user but instead thousand number of users are working on a single server that’s why the cost becomes very less but its effect on the quality of service that is high latency, low bandwidth, and less security.

Virtual Private Server (VPS)

In VPS Server a single server is divided logically into multiple servers by using virtualization and each server is assigned to or leased to different users for their web hosting. It’s more affordable than dedicated hosting as server is shared but with this we have to face lot of compromising in term of resources utilization. Its scalable in nature too. VPS Hosting is a combination of Dedicated and Shared Hosting.

Cloud Hosting

It is the same as a group of multiple servers that provide hosting services. The motto behind cloud computing is to provide 100% availability along with great scalability which one cannot get with above-explained types of hosting. It is achieved because resources are available from multiple servers and if any server goes down then resources can be supplied from other servers.  Cloud computing is the same as VPS but the number of servers is too large and they are distributed so the resources that are required during high traffic levels or spikes for any particular website.

Dedicated Hosting Service

In dedicated hosting a hole server is totally dedicated to our web product. It’s like to allot single  physical server to ones web application. We can have full command on the resources that are available with the server and we do not share any resource to anybody. due to these circumstances this is a somewhat expensive type of hosting but on other side it gives smart performance and great security which no one can neglect considering the quality of service. It’s like someone taking whole luxurious resort on lease (Filling crazy???) !!!!!!!!lol…. but it can empty your hard earned money too…..

Limited or application-specific hosting services include

  • File Hosting Service
  • Web Hosting Service
  • E-mail Hosting Service
  • DNS Hosting service
  • Game Servers
  • Wiki Farms

Conclusion

            Selecting proper hosting service ,it’s a matter of  purpose for which you are going to use hosting service . If you are new and the traffic is not a point of discussion and also money is restricted then shared hosting is best suited , you can anytime upgrade to VPS or dedicated or cloud hosting in future.

            If you want root access along with some sort of security then VPS is the best choice. It also scalable and fast than shared hosting

            If the quality and speed that matters for you by compromising cost then one can opt for dedicated hosting.

            If the business is too large and traffic pattern is also not predictable then go to clod hosting. It also gives great availability and scalability

At last we can understand the whole story with one simple example

suppose we own a car then it’s a physical server. suppose we take car on rent only for sole use purpose then its dedicated hosting. Suppose that rented car has isolated compartment which can be further used by number of users then its VPS hosting. and suppose if the rented car is openly shared by multiple users without any separate space then its shared hosting.

cPanel installation – Step by step guide

cPanel Installation Guide Step by Step

How to install cPanel – Step by step guide

 What is cPanel actually?

If you are a trained network engineer or website builder then it becomes very easy to control server or websites, but if you are the one who is not having any prior technical knowledge then it becomes cumbersome to manage your server /website.

To simplify this difficulty here comes cPanel in the picture. Simply speaking it’s a linux based application which provides graphical user interface to control server /website. It can be handled by anyone with little training.

cPanel is the most widely used and most trusted control panel which is used to control web servers. It is a paid software which was developed by cPanel LLC, a U.S. based software company. Mostly cPanel is provided along with hosting account by hosting service providers with their special hosting plans.

cPanel is simple to use, regular updates are available to improve the performance, also security provided is best in class. cPanel is mostly used by administrators, resellers, and end-user website owners to control the various aspects of website and server administration through a standard web browser.

 

How cPanel looks like?

cPanel has two parts

    WHM panel (server management interface)
  • Create cPanel account for customer 
  • Monitor and protect your server
  • Transfer and backup data in few clicks
    cPanel(user interface)
  • Create website and domain in few clicks 
  • Launch and manage email networks
  • Manage and store web files

What cPanel do for us?

 With cPanel we can do about everything which is required to run hosting account or in broader sense website properly. Some of the key functions are

  • Connect domain names 
  • WordPress installation
  • Upload files to server
  • Manage security setting 
  • Create new database
  • E-mail setup
  • Taking back-ups 
  • Install additional add-on packages
    cPanel(user interface)
  • Create website and domain in few clicks 
  • Launch and manage email networks
  • Manage and store web files

cPanel Installation requirements

    cPanel is installed on hosting server, therefore to install cPanel, few things are must which are 
  • You should have valid hosting plan which comes with main IP and root password.  
  • Server with valid operating system having
    o minimum 2 GB RAM
    o Minimum 40GB Disk space
  • You should have firewall disabled on O.S.
  • You should have active internet connection for ssh (secure shell) session typically for secured command line access for remotemachine.

cPanel Installation step by step guide

let us dive deep into whole process of cPanel installation.

    1. Login to remote server via ssh protocol
    2. If you are on windows and want to login ssh console then you should require PuTTY which is free and open third-partysource terminal emulator to utilize SSH. So just install it and open PuTTY, the window will appear like

      Type the host name which is main IP given by your hosting provider, select port 22 which is by default port for SSH. select connection type as SSH as we are going to login for secure shell connection.

      If you are linux / mac user then they are having native SSH client built into command line. Therefore, open Terminal and type command

      MacBook-Air:$ sshroot@hostname

      Hostname maybe your main IP address given by hosting provider. After executing this command if you are creating SSH session first time then message will appear like this

      Type “yes” to continue.

      Then terminal will ask for root password which was given to you by your hosting provider. Enter correct password, one thing is very strange here that is when you type password it won’t be shown on your display for security reasons. After correct password you will be now successfully logged in into your remote server via ssh.

    3. For some editing purpose you will be requiring text editor. Here in this tutorial we are going to install “nano” text editor which is pretty much common and popular text editor. For this enter following command into terminal window 
    4. MacBook-Air: $ yum install nano

      Then terminal will ask you some permissions, allow that by pressing Yes(Y) and nano will be get installed onto your remote server. 

    5. The next step is to check whether Perl is available onto your server or not. Just check it by typing following command into terminal window
    6. MacBook-Air: $ perl -v

      If it already installed then version number will be displayed otherwise it will show error. In this case you must install it by entering following command into terminal window

      MacBook-Air: $ yum install perl

    7. cPanel installation can be done with auto installer script which will install packages in few clicks. for this we must install curl
    8. MacBook-Air: $ yum install curl

    9. now we are ready to install cPanel & WHM utility onto our server. Just type following command into terminal window
    10. cd /home && curl -o latest -L
      https://securedownloads.cpanel.net/latest &&sh latest

    11. It will take about 40 minutes to install cPanel and WHM onto your remote server. successful installation message will be shown onto the terminal window .
