Accessing the IPMI device to interact with the RAID BiosRegardless of whether your machine has an Adaptec controller or an LSI controller you will need to access the server via IPMI in order to interact with the RAID Bios. In order to interact with IPMI you will first need to connect to the Softlayer VPN.
- Log in to the VPN through either SSLor PPTP. Refer to the VPN topic page.
- Access the Device List in the Customer Portal. Refer to Access the Device List.
- Click on the device you wish to access to bring up that device's page.
- Select the Remote Mgmt tab to find your servers IPMI access details.
- Put the IP of your IPMI device in to the browser and log in.
- To start interacting with the remote console click Remote Control > Console Redirection.
Creating RAID ArraysDuring the boot process hit Ctrl+A to access the Raid BIOS.
To start configuring your RAID you will go in to Logical Device Configuration (first option). This will scan the topology of your drives and present you with a menu where you can manage arrays, create arrays and various other drive administration tasks.
For our purposes we are going to choose Create Array. On the subsequent screen you will be presented with a list of available drives to use in creating your RAID Array.
To select the drives hit the SPACE bar and they will start populating the 'Selected Drives' box on the right side of the sceen. Once you have selected all the drives you would like to use in your array hit ENTER to go to the RAID configuration step. On this screen you will be able to choose the type of RAID you would like. If you need assistance figuring out which RAID set up best suits your needs please see the following FAQ from Adaptec
You will need to provide an Array Label during the configuration. We generally suggest having the type of RAID in the label (Example: RAID10-A). You would then use the enter key to go through the other settings. Most of the defaults will be ideal.
Once you are done with the configuration hit Done and the RAID be built. You can see your new Array by selecting 'Manage Arrays' from the Main Menu. To exit the configuration utility you will hit the ESC key until you are prompted to Exit the Adaptec BIOS
Removing existing Arrays
If you need to remove an existing array you will go to Manage Arrays > Select the Array to remove and hit the delete key. You will then be asked to confirm that you would like to Delete the Array.
- On a server with 6 total drives you could set up 2 SSD's in a RAID0 for your Operating System and 4 additional drives in a RAID10 for your actual data. This allows you to quickly reload the servers OS without having to restore your site or service data if it resided on the secondary array.
- On a cPanel server you could have /var and /home on separate SSD RAID Arrays. Since these are the 2 most IO intensive directories on a cPanel server you could potentially decrease site response time with something like the following:
- RAID0 (2 SATA Drives) - /
- RAID0 (2 SSD Drives) - /var
- RAID0 (2 SSD Drives) - /home
- RAID10 (4 SATA Drives) - /backup
- Use a single RAID array to set up multiple logical partitions. For example using two 4TB drives set up in a RADI1. You could then partition the RAID to fit your needs. One example would be:
- Primary partition of 100GB for your Operating System
- Second partition of 500GB for your data
- Third partition of the remaining space for backups
