Chapter 6. Basic Volume and Host Configuration 

Draft Document for Review January 29, 2013 12:52 pm

The All Volumes window opens (Figure 6-2). If this the first time volumes are configured on a 
newly initialized system, a pop up message appears that no volumes are defined yet.

We have some volumes already and are creating additional volumes in the following sections.

By default, all volumes that you create are striped across all available MDisks in one storage 
pool. The GUI for the IBM Flex System V7000 Storage Node provides the following preset 
selections for the user:

��

Generic: A striped volume that is fully provisioned, as described in 6.1.1, “Creating a 
generic volume” on page 244.

��

Thin-provisioned: A striped volume that is space efficient. There are choices under the 
Advanced button to help determine how much space is fully allocated initially and how 
large the volume is able to grow, as described in 6.1.2, “Creating a thin-provisioned 
volume” on page 245.

��

Mirror: The striped volume consists of two striped copies and is synchronized to protect 
against loss of data if the underlying storage pool of one copy is lost, as described in 6.1.3, 
“Creating a mirrored volume” on page 248.

��

Thin-mirror: Two synchronized copies. Both are thin provisioned, as described in 6.1.4, 
“Creating a thin-mirror volume” on page 251.

��

Compressed: A volume using embedded Real-time Compression technology for reducing 
the size of the volume, as described in “Creating a compressed volume” on page 254

Select which volume you want to create and go to the relevant section.
