Creating a RAID 0 Array

Purpose

A RAID array can improve the overall storage and access performance of drives. If an LSI SAS3108, LSI SAS3408 or LSI SAS3508 RAID controller card is used, you are advised to create a RAID 0 array or a RAID 5 array to fully use the RAID controller card cache (which is 2 GB for the LSI SAS3508 RAID controller) and increase the read/write speed.

Creating a RAID array will clear drive data. Confirm before proceeding.

Procedure

1. Use the storcli64 file to check the creation of the RAID array.

   1	./storcli64 /c0 show

   

   You can place the storcli64 file in any directory for execution. For details about how to obtain the file, see Huawei Server RAID Controller Card User Guide (Arm) .

2. Create a RAID 0 array. Run the following command to create a RAID 0 array for the second 1.2 TB drive. c0 indicates the ID of the RAID controller card, and r0 indicates the RAID 0 array. Perform this operation on all drives except the system drive.

   1	./storcli64 /c0 add vd r0 drives=65:1
