Video Tutorial: How to Configure RAID for Dell PowerEdge Servers

 

 

Our customers often ask for assistance in setting up a RAID array in their new TechMikeNY server.  In this video tutorial, we’ll provide step-by-step instructions for how to set-up a RAID array in a Dell PowerEdge server.  The PERC – or PowerEdge Raid Controller – is an H730, and the server is a Dell R730 – but the steps are virtually identical between all Dell PowerEdge servers. 

When the boot menu pops up → Press CTRL + R.

This will bring up a list of the physical disks available for configuration into a RAID array. 

Click F2 (Operations) → Clear Config.  This ensures that you are removing any previous RAID configuration that existed on the controller and disks. 

Click Yes.

Now with all previous configurations cleared, we can create our new Virtual Disk. 

Select the PERC → Create New VD

Since our server has seven drives, it is standard to make the first two drives RAID 1.   As a refresher, RAID 1 mirrors the data across both drives, creating a copy.  

Click Ok

This will return to the main PERC menu, where you can initialize the virtual disks. 

Select the newly created Virtual Disk.  Click F2 again, select Initialization → Fast Init. 

 Click Ok.  

This will complete the Initiation on this first virtual disk.

We can now use the remaining drives left in the server to create other virtual disks. 

To do so, we repeat the process that we performed on the first virtual disk creation. 

Select the PERC controller at the top of the menu.  Click F2 (Operations) → Create new VD. 

You can select RAID 5, as shown in our configuration here, or RAID 10 (which is typically faster). 

We recommend keeping one drive as a hot-swappable spare.  You’ll notice here [in the above grab] we left one drive off the array – this will be our hot-swap spare. 

From the Advanced Menu, check Configure Hot Spare. 

The Hot Spare then needs to be manually enabled.  A prompt will appear for the drive(s) to be selected to serve as the spare.  Click Ok

This configuration will allow you to have two failed drives without loss of any data.  If one drive fails, then the hot-swap spare will automatically take over the failed drive functions.  While this particular configuration could withstand another failed drive, it is recommended that you replace failed drives as soon as possible

 We then repeat the initialization process for the second VD we created. 

Select our newly created RAID Disk Group → Click F2 (Operations) → InitializationFast Init. → Click Yes.

As before, the Initialization complete notification will pop up.  Click Ok.  

With the virtual disks set-up, click Esc. To exit the configuration menu. 

You will then be prompted to Press Control+Alt+Delete to reboot the system.
