XH270

Operating a RAID system requires at least two or more storage drives. These work together and form a group of drives. This is also more efficient than one single drive.

RAID systems offer the following advantages: - Increase reliability (redundancy) - Increase data transfer rate (performance) - Structure of large logical drives - Cost reduction through use of several small, less expensive drives

The XH270 supports the following raid levels:

Raid Level Explanation Pros Cons Number of possible hard disks in XH270Volume capacity
RAID 0
Striping means a mode of operation where data is shared across multiple disks to improve performance.Increased transfer rate No protection from loss of data 2, 3, 4 Sum of all disk sizes
RAID 1
Writes identical data to both hard disks at the same time.Provides data redundancyOnly 50% volume capacity 2 per RAID Smallest hard disk size
RAID 5
Implemented block-level striping with parity data shared across all included disks makes data redundancy more efficient than RAID 1. More efficient data redundancy than with RAID 1 - 3, 4 (X*- 1) x (smallest hard drive size)
RAID 10
The combination of RAID 0 and RAID 1 doubles the performance as compared to RAID 1.Doubles the performance in comparison to RAID 1 Low total capacity 4 (X* / 2) x (smallest hard drive size)

How to set up a RAID configuration on XH270?

The following requirements must be met before setup.
The XH270 must be ready for operation with at least two hard disks installed and connected to the SATA ports.
Boot Mode in BIOS must be set to UEFI.


1.)

Power on the XH270 and while booting please press the “Del” key to enter BIOS. Navigate to the “Advanced” tab, and enter “SATA Configuration”.


2.)

- Under “SATA Mode Selection” select “RAID”.
- Now save your settings by pressing the F4 key on the keyboard and restart the XH270.


3.)

- Now go to the “Advanced” tab again and enter “Intel Rapid Storage Technology”.


4.)

- Click on “Create Raid Volume”.


5.)

- As the next step, you have the possibility to name the RAID volume (1.).
- Now select a RAID Level (2.). To find out which RAID level is right for you, please refer to the table as “above ”.
- By pressing the space key, you can add the individual hard disks to the RAID volume (3.).
- Finally, please confirm the settings with “Create Volume” (4.).


- To check the RAID settings once again, you can review all information about the created RAID configuration in the next menu or even delete it.


Now your RAID configuration has been created successfully and an operating system can installed.
