RAID

Creating Manager

RAID has different levels (such as RAID5, RAID6). Each level has different data protection, data availability, and performance grade. You can manually create RAID or just one click one button to create RAID. For create RAID function, you can select the physical HDD that does not included in the RAID group or the created disk array to create a RAID5. You can refer to the following situations:

• There is no RAID, no hotspare disk: System directly creates the RAID5 and creates one hotspare disk at the same time.
• There is no RAID, but there is a hotspare disk: System creates the RAID5 only. It uses previous hotspare disk.
• There is RAID: System cancel the previous RAID setup and then create the new RAID5. System creates the hotspare disk if there is no one. System uses previous hotspare disk if there is hotspare disk available.
• The background will format the virtual disk.

You can create different types of RAID as needed.

Step 1 Select Main Menu > STORAGE > RAID > RAID. The RAID interface is displayed.

Step 2 You can click Create RAID or Create Manually, and all the disks involved will be formatted.

• Click Create RAID, the system will create RAID automatically.
• If there is no existing RAID and no hot spare disk, the system will create RAID5 and a hot spare disk automatically.
• If there is no existing RAID, but existing hot spare disk, the system will only create RAID5 and use the existing hot spare disk automatically.
• If there is existing RAID and existing hot spare disk, the system will delete the original RAID and create RAID5 with all the disks and use the existing hot spare disk automatically.
• Click Create Manually.

1) Select RAID type and disks as system instructed.

2) Click Create Manually, and then the format disk notice is displayed.

3) Click OK.

Step 3 After creating RAID, the disks need to sync with each other to finish the process. For RAID5 and RAID6, you can select different working mode.

• Self-Adaptive: Automatically adjust the RAID sync speed according to the business status.
• When there is no business running, sync is performed at a high speed.
• When there is business running, sync is performed at a low speed.
• Sync First: Resource priority is assigned to RAID sync.
• Business First: Resource priority is assigned to business operations.
• Balance: Resource is evenly distributed to RAID sync and business operations.
