Storage Center 7.2 Scalability
The following scalability guidelines apply to Storage Center 7.2.
Storage System Scalability Guidelines
The following scalability guidelines apply to SC9000, SC8000, SC7020F, SC7020, SC5020F, SC5020, SC4020, SCv3000 Series, and
SCv2000 Series storage systems.
NOTE: Raw storage space is expressed in decimal units (for example, 1 TB = 10
12
bytes). Addressable storage space is
expressed in base 2 units (for example, 1 TB = 2
40
bytes). Therefore, a 1 TB drive measured in decimal units is equal to 0.909 TB
base 2 units.
