Why Data Storage Systems are important? And what are the types?
Data storage systems are basically devices designed for temporary or permanent storage, protection, classification and reuse of pictures, files and documents in digital media.
In general, Data Storage Systems are grouped into three main groups ;
1. DAS (Direct-Attached Storage): Directly host computer is the storage system that is connected to the personal computer and its managed by this computer. They do not work in a network dependent state. DAS devices include floppy disks, optical discs—compact discs (CDs) and digital video discs (DVDs), hard disk drives (HDDs), flash drives, and solid-state drives (SSD).
Advantages;
- Easy to install.
- They are Low Cost.
- DAS can provide fast access to data and support high performance I/O operations
Disadvantages;
- They have limited capacities. It can be configured using a RAID system, but supported architectures are limited by the number of disks attached to the server and the server's operating system (OS).
- DAS storage can be shared with others, but only at the operating system level.
- An administrator can enable sharing by allowing other machines to connect to the server and access some of the storage.
-DAS systems are directly connected to the host via a single point, all access is lost upon disconnection
2. NAS (Network Attached Storage): It allows multiple computers on a network to share storage at the same time.
It is accomplished with multiple hard drives or other storage devices in a RAID configuration. The basis of the binding system is access over a computer network (usually via TCP/IP). It has a network interface card to connect directly to a switch or router.
Advantages;
- It allows file sharing between different operating systems.
- It is easy to install and configure.
- Can take a snapshot of data (snapshot)
- It can create easily scalable disk storage.
- Easy installation and management.
Disadvantages;
- NAS systems are connected to the host via a single point on the network, all access is lost when the connection is broken.
- It has limited scalability.
- It is file oriented.
- In case of heavy network traffic, performance loss is observed.
- NAS is not suitable for data transfer intensive applications.
- It is slow for video application or multiple large files.
3. SAN (Storage Area Network): Storage space needs of organizations have caused them to switch from conventional file servers to more advanced SAN solutions.
SAN systems are a storage architecture that connects storage systems and application servers over a network through a fast and reliable access infrastructure between Application servers and storage systems.
SAN systems are architecturally different from NAS in that they provide block-level storage versus file-level storage. They use high-speed networks such as Fiber Channel to provide data access to the storage unit. The storage requirements of companies are constantly increasing.
Compared to a traditional file server solution, SAN systems are highly expandable without reducing uptime.
The direct connection between the server and storage units causes the performance to increase. It is seen as an ideal solution for backup, recovery and increased efficiency in communication.
Advantages;
Data Transfer and access time is fast.
It is highly and easily scalable.
It provides high durability and accessibility.
It provides mirroring feature in the file system.
It provides the possibility to use the storage space directly.
Disadvantages;
They are expensive systems, require advanced hardware investments.
Because SAN systems consist of elaborate and complex interconnected devices, there is implementation complexity.
It cannot work as a standalone device.
