HP 3PAR InForm OS 3.1.1 Concepts Guide

1 Introduction

Audience

This guide is for all levels of system and storage administrators. Anyone who plans storage policies,

configures storage resources, or monitors the storage usage of HP 3PAR Storage Systems should

read this guide.

User Interfaces

Two user interfaces are available for the administration of HP 3PAR Storage Systems: the HP 3PAR

InForm OS Command Line Interface (CLI) Software and the HP 3PAR InForm OS Management

Console Software. Unless otherwise stated, all tasks can be performed with both the CLI and the

Management Console. Refer to the HP 3PAR HP 3PAR InForm OS CLI Administrator's Manual and

the HP 3PAR InForm OS Management Console Online Help for instructions on how to perform the

tasks described at a conceptual level in this guide.

Units of Measure

• All units of storage (capacity) are calculated base 2 (x 1,024).

Therefore:

• 1 KB = 1,024 bytes

• 1 MB = 2

bytes = 1,048,576 bytes

• 1 GB = 2

bytes = 1,024 MB = 1,073,741,824 bytes

• 1 TB = 2

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

bytes = 1,000,000 bytes

• 1 GB = 10

bytes = 1000 MB = 1,000,000,000 bytes

• 1 TB = 10

bytes = 1000 GB = 1,000,000,000,000 bytes
