CHAPTER 14 STORAGE LAYOUT• DATA_DG• RECO_DG• SYSTEM_DGThis storage cell is configured with SATA disks, so the total space per storage cell is 21.76 terabytes.Table 14-4 shows what the allocation would look like. In all cases the physical disk size is 1,861.703125.The sum of the disk sizes is then 22,340.437500.Table 14-4.
