1.2 User Interfaces
Two user interfaces are offered as part of the 3PAR InForm® operating system: the 3PAR
InForm Command Line Interface (CLI) and the 3PAR InForm Management Console graphical
user interface. This manual discusses the InForm CLI. For information about the InForm
Management Console, refer to the 3PAR InForm OS Management Console Online Help.
The InForm CLI enables expert users to execute some advanced tasks not currently available
through the InForm Management Console. See the InForm OS Command Line Interface
Reference for more information. The InForm CLI also enables you to configure 3PAR Remote
Copy. See the 3PAR Remote Copy User’s Guide for more information.
1.3 Units of Measure

◆ 1 MB = 2
20
bytes = 1,048,576 bytes
◆ 1 GB = 2
30
bytes = 1,024 MB = 1,073,741,824 bytes
◆ 1 TB = 2
40
bytes = 1,024 GB = 1,099,511,627,776 bytes
■ All units of performance (speed) are calculated base 10 (x1000).
Therefore:
◆ 1 KB = 1000 bytes
◆ 1 MB = 10
20
bytes = 1,000,000 bytes
◆ 1 GB = 10
30
bytes = 1000 MB = 1,000,000,000 bytes
◆ 1 TB = 10
40
bytes = 1000 GB = 1,000,000,000,000 bytes
