Setting up Storage
_____________________________________________________________________
Setting up a storage pool is required before you can create volumes for data. You can do this
either through the GUI (as explained below) or with the CLI (see Quick Start Tasks: Management
in the About the Command-Line Interface (CLI) section of the ION Accelerator Appliance CLI
Reference Guide. There are a few considerations in choosing between the GUI and CLI for create
a storage pool:
• You can create multiple storage pools with either the GUI or the CLI.
• Commands for adjusting RAID configurations are found in the CLI but not in the GUI.
See Naming Requirements at the end of this section for rules on choosing names for storage
pools, volumes, initiators, initiator groups, aliases, and targets in ION Accelerator.
ABOUT STORAGE POOLS FOR ION ACCELERATOR
Four types of storage pools can be created, each with its own storage profile (description of the
pool type). These storage profiles are described below.
Storage Profile Types
The basic types of storage profiles are described below. In each case you can click the “More
Details” link next to the profile description to get additional information.
• Reliable Performance (default) – Reliability and performance are emphasized over
capacity, using a RAID 10 configuration. Storage is divided into two equal segments that
are mirrored to each other, so that an unlikely failure of an ioMemory module will not
result in data loss. This configuration requires a minimum of four ioDrives or additional
increments of two ioDrives, which must all be the same type and capacity.
• Maximum Performance – Performance is emphasized, using a RAID 0 configuration. This
does not provide redundant storage. With this configuration, the storage capacity is
striped across the available ioDrives (minimum 2) installed in the server. All ioDrives in this
profile must be of the same capacity.
