๏ RAID - Redundant Array of Independent (or Inexpensive) Disks

๏ Combines multiple disk drives into a logical unit to provide faster data transfer speed and/or higher reliability, depends on the RAID level

๏ Most higher-end hardware RAID controller can support standard RAID levels such as RAID 0, 1, 5..., as well as nested RAID levels such as RAID 0+1, 1+0...etc

What is RAID?What is RAID?

๏ Able to combine multiple disks into one big disk so that no disk space will be wasted

๏ Able to create one or more redundant copies from a single source disk to prevent data loss caused by hardware failure

๏ Able to gain much higher read/write speed for applications which requires large amount of data transfer and access needs

๏ NAS - Network Attached Storage

NAS storage provides both storage and file system, to the client computer, a NAS storage often appears as a “share folder”.

๏ SAN - Storage Area Network

SAN storage provides storage only, and the file system is handled by the operating system, a SAN storage appears to be “locally attached” to the client computer, which can be partitioned and formatted to a desire file system.

What is NAS & SAN?What is NAS & SAN?


NAS is often slower than SAN due to multi-protocol (multiple translations), but can be accessed by multiple clients at the same time.


SAN is like a external hard drive but connects through a network connection. Due to this reason, a SAN shouldn’t be accessed by multiple computers at the same time (unless accessed using read-only permission).

Creating a Logical UnitCreating a Logical Unit

๏ Group multiple “physical disks” together as a “Volume Group”

๏ Slice the volume group up into “User Data Volume”

๏ Assign a user data volume as a “Logical Unit” which can then be connected by the client (using an iSCSI initiator)
