*1: Use of RAID0 is not recommended because it is not redundant. For RAID0 configurations, data may be lost due to the failure of a single
drive.
It is not recommended to use SSDs in a RAID1 configuration that has a high I/O access load because the number of rewrites may exceed
the limit within the product warranty period.
*2: Fujitsu original RAID level that provides the high speed rebuild function, and striping with double distributed parity.
*3: The maximum number of RAID groups that can be registered (for the RAID1 configuration).
*4: The maximum number of volumes that can be created in a TPP is calculated by subtracting the number of RAID groups that configure the
relevant TPP from the maximum number of volumes that can be created in the ETERNUS AF.
