What is Network Storage? 3 types & Features of Block Storage

What is network storage

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.

4 Major Differences Between Block Storage vs Object Storage – a perception of Technical variance

Table Of Contents

Introduction of Object Storage vs Block Storage


Object Storage concept is the advanced medium of storage, here data is stored in the form of an object.

The data comes in different sizes and formats, from any personal image to a 600,000-pages research manual for assembling big machinery. We cannot directly map objects to any specific file. They may be a small part of a file or collection of data isolate from any file contents. The metadata is always extensible. The metadata belongs to the creator of data and what type of data is available.  Using unique identifier numbering of data, it is easily accessible over a distributed network.

With block storage technology, data is split into equal-sized blocks and each has its unique address. These blocks don’t have metadata information, so could not find actual information of blocks. On the other hand, Object Storage saves the entire data blocks and information about types of data saved. You can save infinite data with object storage, which makes this technology strong and tailored.

Metadata contains information about the security and the importance of software connected to that information. When any user posts a Facebook image or saves the song on the Spotify app has actually shared data on object storage even if a user is unaware of it. Object Storage can be editable only in the whole unit, access to object storage needed to edit and overwrite it. This causes performance inference.

Another major difference is that through the operating system it is easy to access block memory like mounted drive blocks.  On the other hand, object storage degrades its performance while accessing like a hard disk drive.

Concept of Block Storage



Block Storage divides data into small blocks of memory. Each block of memory has its separate space with a unique identifier number.  This identifier allows the framework to use small data blocks whenever needed. Block storage is useful on both Linux and Windows platforms.  Block Storage can be install and configured and spread in the user’s network. The block storage software is responsible to collects the data blocks and send them to the end-user.

In a storage-area network (SAN), block storage plays a vital role to perform functioning of various server nodes.  Block storage is accessible through many paths so, unlike File storage, it is very easy to retrieve with its individual living power. It is useful for companies executing huge transactional activities and use big data applications. If a huge data is required to save, it is good to use block storage. There are some flaws like Block Storage is costly and limited scope to work with metadata.

Concept of Object Storage



Object Storage includes distributed files over the hardware and data is spread with multiple units i.e. Object. Instead of keeping files on blocks of servers, objects can be saved in one repository. Each Object Storage is a self-develop repository and assigned with a unique identifier, so it can be easily searched over a distributed system. The information or metadata for Object Storage is accessible using details like the date and time of the captured video, also details about the camera and artists in the video. Object Storage uses HTTP protocol and its API for cost-effective service. It provides a scalable environment in public cloud platforms and big data applications. It is useful for applications where unstructured data is used.

Workload Management for Block Storage and Object Storage



 Objects storage is useful for unstructured data, this technology is used to write data once and read multiple times. Web contents, database records, video streaming, images, music can be stored in object format. Unstructured data is usually stored in object form, where no more edits and writes required. Another advantage of Object Storage is that it is geographically located and can connect using network services. Object Storage model is not good for transaction-based systems, because of the consistency constraints cause. Object Storage is not used in NAS for file sharing and retrieving. Also, it does not use to maintain, lock, and share a single storage version of data.

On the other hand, Block Storage can easily retrieve by OS, as per different use cases. The structure data format is one example of block storage, it also includes multiple read and writes mechanisms. Virtual Machine File System (VMFS) is another example of a Block Storage system.

Why Block Storage?



Block Storage is beneficial for the file systems to edit and retrieve blocks according to user needs. But on the other hand in the Object Storage editing file means, upload a new version of the entire block. It causes a huge impact on performance if multiple changes are periodic. Also, Block Storage gives a significant performance in IO Speed while Object Storage speed depends on the HTTP framework. Block Storage is implemented on servers with various protocols like CIFS, NFS etc. and it is usually designed for file handling. An object-oriented framework is not capable of high functioning in the database, memory cache, and system logs.

In the Block Storage file, size is allocated and split into fixed storage blocks. These blocks are editable and expandable by adding extra nodes. Block framework is widely used for big data handling, IOPS, and transactional systems. Object Storage basically has an HTTP interface and can store infinite files virtually with revisions of a file. Objects are distributed in multiple physical servers located in different locations around the globe.

Main Differences Between Block Storage vs Object Storage


In this section we will see main technical differences between Block Storage vs Object Storage.

Capability Strong capacity to handle big data and transferable data. Capable to handle big data and high  performance throughput.
Distance The distance between the storage server and the application server affects the performance and latency. Objects  can be stored across multiple areas of remote location.
Adaptability Due to conflicts in addressing strategy, it’s hard to maintain scalability. Can save data  as much as you want from  petabytes and infinite.
ANALYTICS No Metadata allowed. Tailored metadata allows data to be easily managed and accesses.




Based on the Block Storage vs Object Storage discussion, it is observed that for a huge amount of data handling Object-based storage is good. Where, Block Storage is good for IO resolute storage, like Database and transactional systems. VCCLCloud offers advanced Block Storage without dropping the efficiency of end-user applications and data. You can grasp the fair pricing of VCCLCloud, Block Storage service SSD Storage when you require it, and there is no hassle of ranking in a standard format.
