Storage Area Network
Storage Area Network architecture is designed to consolidate and centralize the storage of all types of data. The storage systems enable booting from a central disk array within SAN network, which ensures a way to easily and quickly replace system hardware and backup data that are not limited to the server - the operating system and its file system.
The benefits of this backup method:
- transparent to the operating system,
- streamlined management of system resources,
- optimal use of disk capacity.
In addition to these benefits, SAN networks offer a number of other benefits, such as a unified storage environment, a central view and administration of disk capacity, and additional functionalities (replication, mirroring, data recovery, load balancing) important for ensuring the high availability of data and IT systems.
The SAN architecture is the basis for:
- server clusters requiring high availability,
- setting up and mirroring of data during system recovery in the event of failure,
- quick backup,
- quick data recovery.
The SAN architecture is most commonly used in small and mid-sized IT environments where high availability of all types of data is of primary importance.
