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:
- Format as “Software RAID”
- 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.
