How to Configure Raid 10 on Dell Poweredge

Raid stands for Redundant Array of Independent Disks. The purpose of raid is to store information's (data) in multiple Hard disk (SAS, SCSI, SSD and etc) to increase the protection level and performance of the data. Here we are configuring Virtual Disk with Raid 10 on Dell Poweredge R720 Server, this configuration can also be helpful on any Dell Poweredge server's. Raid 10 is a combination of mirroring and stripping.

Raid 10 = Raid 1 + Raid 0

Due to Mirroring "Raid 1" if one hard disk is fail the data will be available on other hard disk, in that case replace the fail hard disk the data will re-sync again. Stripping (Raid 0) is not provide a redundancy, in Raid 10 stripping (Raid 0) is use to connect the two Raid 1 with each other.

Raid 10 is secure due to higher level of data protection (Raid 1) and fast due to stripping of data (Raid 0) means data is available on multiple disk.

Here we are creating Virtual Disk with "Raid 10" Configuration, we are using 4 disk with sizes of 2TB each. In Raid 10 minimum 4 disk is use to create it. 

In Dell Power edge Servers (R210, R410, R710, R720, R730 and etc) press Control+R for the configuration of Virtual Disk. 

In the below mention image, you can see that 4 disk with size of 2TB is being used for the creation of Virtual Disk with configuration of Raid 10.

To create a new Virtual Disk press F2 on "PERC H700 Integrated" then click on "Create New VD".

Configuration of New Virtual Disk:

Raid Level: RAID 10.

Physical Disks: Select at least 4 Physical Disk.  

VD Name: Host.

Read Policy: Adaptive Read Ahead.

Write Policy: Write Through

Initialize (Select) 

Set all above the settings then press "OK".

After press "OK", it is give a warning window that "Initialization will destroy data on the virtual disk. Are you sure you want to continue?". Press "OK"  to continue.

 The Virtual Disk "0" has been created with configuration of Raid 10 that is mention in the below image.

After successful configuration of New Virtual Disk press "esc" for exit then press "OK".
