Table 42. RAID capacities for RAID 10 arrays (continued)

Notes:
1. Disk-drive and flash-drive sets contain 16 disk drives. Half-drive sets contain 8 disk
drives.
2. Physical capacities are in decimal gigabytes (GB) and terabytes (TB). One decimal GB is
1,000,000,000 bytes. One decimal TB is 1,000,000,000,000 bytes.
3. Rank capacities of DS8880 are different from rank capacities of earlier DS8000 storage
systems. This change in the number of extents must be planned for when you move or
migrate data to the DS8880.
