Dell PowerVault ME5 Series Storage System CLI Reference Guide

Size representations

Operating systems usually show volume size in base 2. Disk drives usually show size in base 10. Memory (RAM and ROM) size is always shown in base 2.

In the CLI, the base for entry and display of storage-space sizes can be set per user or per session; see create user and set cli-parameters. For entry of storage-space sizes, unless a base-2 or base-10 unit is specified, the unit is 512-byte blocks. If your base is set to 2, when you set a size, whether you specify a base-2 or base-10 size unit, the resulting size will be in base-2.
