5270 Appliance front panel drive configurations
The 5270 Appliance contains 3 NVMe solid state drives, and 8 SAS hard disk drives, which can be accessed from the appliance's front panel.
The drives that are located in D0 and D1 are configured as the RAID1 device. These drives contain the appliance operating system and the Flex application along with the log files. You can hot-swap one of these drives at a time; however, you cannot operate the appliance if both drives are removed.
The drive in D2 acts as a hot spare for OS and log files. D3 is a blank slot with empty carrier.
The drives in slots D4-D10 store user data. They are configured as a RAID 6 array, which uses block-level striping with two parity blocks across each of the drives in the volume.
The appliance uses the drive that is located in D11 as a dedicated hot-spare drive. If one of the drives fails in D4-D10, the appliance automatically initiates a RAID 6 rebuild operation. It rebuilds the RAID 6 array by using the hot-spare drive in D11. After you replace the failed drive, the appliance then copies the information from the drive in D11 to the new replacement drive. When the copy operation finishes, the drive in D11 again becomes the hot-spare drive.
Note:
The hot-spare drive size depends on the data drive size.
Warning:
The drives are pre-formatted before the appliance is shipped. Do not rearrange the drives from their original locations.
