DAS storage solution, for example, the storage system in the server disk, disk file system management, is a complete system, in order to solve the data sharing and access,
And the distributed file system is also in order to solve the storage, sharing, in a distributed file system, data is stored in a lot of disk, the file system management of the whole storage space,
Where is the difference between the two above?

CodePudding user response:

From the user level, storage solution and distributed file system can provide a storage space, this is the same;
From its internal relations, the distributed file system each device is connected to the Internet, will each storage space allocation form a logically unified storage
SAN nas is with dedicated storage device (can be understood as multiple hard disk with a big hard disk) physical connection special equipment from speed to provide special storage capacity, the physical can be treated as a single device

CodePudding user response:

Das block storage
File system is based on block storage, usually related to OS, for example: a U disk or iSCSI disk is block storage, but formatted as NTFS and corruption is file storage,,,

CodePudding user response:

NAS and SAN is refers to the hardware storage devices, distributed file systems from storage file system, that is to say the NAS, SAN can be used as a distributed file system, can also be used as a distributed file system,

CodePudding user response:

Block storage, NAS, object storage, the essential difference is that the data organization,
DAS, SAN (IPSAN) is a connection (direct or through a fibre channel, IP)
Distributed way is to deploy, original equipment is centralized or tight coupling, such as controlling a machine, a distributed is loose coupling, such as the two controllers are two servers,

Block storage, NAS, object storage, essential difference is that the data of the organization? This is how to understand?

CodePudding user response:

Upper data to storage, what kind of data in a storage device USES the conservation and management way,
As the name implies, block storage is a data block, according to a NAS is a file, according to a object storage is to press a save an object,
