Dell PowerVault ME5 Series Administrator's Guide

Size representations

Parameters such as names of users and volumes have a maximum length in bytes.

When encoded in UTF-8, a single character can occupy multiple bytes. Typically:

1 byte per character for English, Dutch, French, German, Italian, and Spanish
3 bytes per character for Chinese, Japanese, and Korean

Operating systems usually show volume size in base-2. Disks usually show size in base-10. Memory (RAM and ROM) size is always shown in base-2. In the PowerVault Manager, the base for entry and display of storage-space sizes can be set per user. When entering storage-space sizes only, either base-2 or base-10 units can be specified. The locale setting determines the character used for the decimal (radix) point.

Table 1. Storage size representations in base 2 and base 10
Base-2		Base-10
Unit	Size in bytes	Unit	Size in bytes
KiB (kibibyte)	1,024	KB (kilobyte)	1,000
MiB (mebibyte)	1,024²	MB (megabyte)	1,000²
GiB (gibibyte)	1,024³	GB (gigabyte)	1,000³
TiB (tebibyte)	1,024⁴	TB (terabyte)	1,000⁴
PiB (pebibyte)	1,024⁵	PB (petabyte)	1,000⁵
EiB (exbibyte)	1,024⁶	EB (exabyte)	1,000⁶

The locale setting determines the character used for the decimal (radix) point, as shown in the following table:

Table 2. Decimal (radix) point character by locale
Language	Character	Examples
English, Chinese, Japanese, Korean	Period (.)	146.81 GB 3.0 Gb/s
Dutch, French, German, Italian, Spanish	Comma (,)	146,81 GB 3,0 Gb/s
