Introduction and full review of GlusterFS
I, Arslan Mirbzergi,I intend to talk to you in this article about GlusterFS and its features. GlusterFS is a distributed File-system and Scalable that collects storage components from multiple servers in a Uniform File-system. File-systems work in Background, and no one pays attention to them after installation. File-system often changes when data is lost or restricted for reasons such as using the maximum partition size or restrictions on the storage path.
Introduction to GlusterFS:
The name “Gluster” is a combination of “GNU” (which itself stands for “GNU’s not Unix”) and “Cluster”. This system is released with GNU-General Public License, which makes it free to use. The term “Cluster”, in conjunction with data carrier, is used to describe a combination of physical storage units. It is also used in conjunction with computers to represent a connected network of multiple systems. GlusterFS integrates these concepts by combining storage space from network-connected computers and using it as a Logical entity.
The project was published in 2005 by Gluster Inc. In 2011, Linux RedHat took over the company’s management and has continued to develop File-system ever since. The seventh version of GlusterF was first performed in January 2020 and has been precompiled for some Linux versions such as CentOS, Debian, Fedora, RedHat/RHEL, SUSE and Ubuntu.
It is for Unix-based operating systems and is still not stable enough for Windows systems due to memory integration into the FUSE module.
The FUSE note stands for Filesystem in Userspace. Operating systems are usually divided into User and Kernel modes. Kernel mode is especially safe. For example, only people who are members of the administrators group can access Kernel mode. Thus, installing and managing drives is typically done only by a network administrator. However, FUSE also allows other users to manage File-system.
Computers can act as servers and clients. Access to File-system is also possible through other supported systems such as Network File System and SMB/Block Message Server/Common File System.
Features of GlusterFS:
A distributed File-system is only meaningful when multiple computers are connected to each other. In files published by GlusterFS, at least three servers are required. Almost any kind of physical hardware can be integrated. In addition to conventional computers, it is also possible to use Virtual machine. In addition to flexibility, this brings many other benefits.
Integrated servers act like Nodes connected to each other through the TCP/IP network. Integrated devices create a reliable Storage pool where memory is provided as Brick, and then these bricks are made of Volumes. Volumes can subsequently be integrated and used, such as normal Data carriers. Computers with access are known as Client, but it is possible that a computer is both a server and a Client.
The extraordinary Scalability property of this software is a special feature. This means that any number of Node and Brick can be added later, and the size of the storage space can also be adjusted according to the new requirements. The storage space to be managed has a maximum size of several Petabytes.
GlusterFS ensures reliability with the help of Redundancy. The risk of bad performance is initially distributed between several systems that can also be spatially separated. It is also possible to set up RAID networks. However, contrary to the standard specified for Distributed volume, a Storage Storage should also be stored in this mode. In this way, each file is saved twice, which is called RAID mirroring.
Redundant Array of Independent Disks is a network of physically independent hard disks from which a Unified drive is created. Depending on your goal, the focus of the work can be on speed or data security. That’s why storage space is reduced by repeatedly saving data or storing the additional information needed to recover the file.
GlusterFS offers ten predefined translators for operations in the storage space. These commands are translated to run to given users. The “storage” translator that stores data in the local File system and controls access to it, and the “encryption” translator, are two examples of these translators.
There is a new function called Geo-replication that can be used to run asynchronous distribution of data among servers in different locations. This protects servers from physical and external effects such as fire or theft. In this case, one computer acts as Master and the other acts as Slave. Data transfer is also protected by Secure Shell.
Advantages and disadvantages of GlusterFS:
In the table below, a distributed File-system with a Conventional network memory is investigated:
GlusterFS basically creates a Classic cloud. Storage space within the network is available to connected clients. GlusterFS is especially suitable for large networks that don’t already have enough resources to build a group network.
Since systems are connected via Internet Protocol, the use of distributed File system is especially suitable for corporate structures that include multiple branches. However, Dedicated network memory can also be stored on restricted local networks.
One notable option against GlusterFS is Ceph, which is available for free and also offers many of the benefits mentioned in distributed File systems. Ceph and Gluster each have their own different advantages and disadvantages.
BeeGFS and former FhGFS are also made by the Fraunhofer Association in Germany specifically for powerful computer systems. The app is available for free and focuses on easy-to-use functionality.
In the business sector, systems such as Storage Spaces Direct S2D have been added by Microsoft. However, the use of this system is limited to Fee-based Windows-licensed servers.
