There are three main technologies for data storage on hard disk:

  • local storage (DAS)
  • storage on a standard network (NAS)
  • storage on a specialized network (SAN)

Each technology has strengths and weaknesses. While the local storage is the most widespread and has a high level of performance, network storage offers the possibility to share data between different servers. This last feature is increasingly sought either to synchronize data between different servers, to consolidate disk space or to enable advanced virtualization architectures.

disque durRAID (Redundant Array of Independent Disks) is a technology allowing a higher level of storage reliability and performance from disk-drive components via the technique of arranging them into arrays.

The various RAID architectures are designed to meet at least one of these two goals:

  • increase data reliability
  • increase Input/Output (I/O) performance
