Overall, the storage systems are South Africa Phone Number List on 4 data hosting infrastructures: DAS, or Direct Attached Storage The DAS corresponds to a storage system directly connected to a single computer or a server. It is not on a network, so other devices cannot easily access it. The example of DAS that everyone can know about is your computer’s hard drive. In order for a computer A to be able to access the data stored on the hard drive of a computer B, it is necessary to remove the hard drive from computer B and physically connect it to computer A, or configure a connection between the two computers . the SAN, or Storage Area Network A

SAN takes the form of a cabinet containing several disk bays connected to the IS by a dedicated network. It enables what is called block storage. The hard disks are not directly connected to the server however the storage arrays are directly accessible in block mode by the file system of the servers. Basically, each server sees the disk space of a SAN as its own hard drive. It allows you to pool storage resources and connect a disk to several machines simultaneously. the NAS, or Network Attached System A NAS is a storage array that has both its own operating system dedicated to data management, configuration software, its own file

system and an independent set of drives. The NAS is attached to the network to serve as a file server. The disks are not connected to the server but to the NAS and allows client access to data without going through an application server. NAS provides access to the same files to multiple servers simultaneously and is ideal for applications that place heavy demands on file systems. In the NAS, the data exchanges between the servers and the disks are done in file mode, unlike the SAN and DAS where the exchanges are in block mode. the Cloud, or Cloud … The Cloud consists of outsourcing storage processing to remote servers.

Storage is then sold as a pay-per-use service with generally scalable billing based on actual consumption. There are 3 types of Cloud storage: the public cloud: the equipment of a service provider is used by several companies. The user no longer has to worry about the equipment, its maintenance and its evolution the private cloud: infrastructure specific to the company, making it possible to keep confidential data internally. This dedicated infrastructure involves very significant costs. the hybrid cloud: joint use of the public and private cloud depending on the criticality of the data File storage, block storage and object storage:

Quésako? Each storage system favors its own storage method, some of which may combine several. There are 3 types of storage methods: File storage , or File storage You are all already familiar with this type of storage. Anyone who has ever saved a file to their PC, Mac or laptop has experienced File Storage. The files are saved as a whole to a specific location on the hard drive. File Storage does not separate data from a file. The file is saved as a whole and is reopened in that form. The hierarchy is obtained by the system of directories at several levels. This results in long enough directory paths that the computer system or a server

must know. The paths allow you to navigate so that you can reopen the files. The information is saved in the form of metadata. Block storage , or Block storage While for File Storage all files are saved in the folder system, for Block Storage, the data is saved as a block at the most relevant location depending on the system, which divides the files into uniform blocks. The files then lose their proper meaning and become difficult to execute or open. The blocks here are units of the same size. So that the different blocks can be found, an address is assigned to each of them. If the server receives a request, it can locate the data.
