Disks|Software RAID

RAID an acronym for

  • redundant array of independent disks.
  • originally redundant array of inexpensive disks.

RAID is a way of storing the same data in different places (thus, redundantly) on multiple hard disks.
XigmaNAS provides a front end to create Software based RAID. That mean you don't need special Hardware ( mostly expensive) to setup a RAID. Currently XigmaNAS supports following RAID Levels

  • JBOD - Just A Bunch Of Disks
  • RAID 0 - Block-level striping without parity or mirroring
  • RAID 1 - Mirroring without parity or striping
  • RAID 5 - Block-level striping with distributed parity

and combinations like

  • RAID 10
  • RAID 01

Click menu Disks > Software RAID and you see the Software RAID > GEOM > Management page as shown below:

From here we can setup various software raid setups.

For a good explanation of the different RAID-Levels see RAID
Important - RAID does not equal backup. Even if you create a RAID array you must still keep another copy of your data in a different location.

Before you can Setup a RAID you have to prepare the disks you want to use.
For more information about “Preparing Drives for RAID” see
Disks management

Note - Step by step instructions for removing / replacing failed drives in SoftRAID1 and SoftRAID 5 arrays are available in Software RAID Configuration & Management and in FAQs:
Software RAID and Encryption

If you like to encrypt a Software RAID it is suggested to do the following steps:

  1. Format as “Software RAID”
  2. Setup your Software RAID array
It is not suggested to encrypt on top of a Software RAID, this could cause loss of data if the RAID fails.
