ezRAID3 Manager GUI Version 1.0
4 Advanced Configuration
This section describes how to use the Advanced Configuration Wizard to apply more than
one storage policy to volumes on the SteelVine Storage Reference Design. This mode is
entered by selecting the GUI-only position on the rotary switch, if the Advanced
Configuration feature is enabled for your system (refer to Chapter 1 Introducing the
SteelVine Storage Appliance). In addition, if you are using a SATA host connection, your
SATA controller must be Port Multiplier aware.
Why Advanced Configuration?
The Basic Configuration Wizard provides predefined storage policies to quickly configure
the SteelVine Storage Reference Design. Each predefined storage policy allocates the total
system capacity to the selected
JBOD, SAFE, FAST, or BIG storage policy. The SAFE33
and SAFE50 storage policies are not available in the Advanced Configuration Wizard
(although equivalent SAFE and BIG volumes can be configured manually).
Using the Advanced Configuration Wizard, you can configure two volumes, (with the same
or different storage policies), on the two hard drives. The following configuration options
are possible, where each of the two volumes is allocated some portion of the total system
capacity:
x Two SAFE volumes that are mirrored from one hard drive to the second drive.
x Two FAST volumes that are striped across the two hard drives.
x Two BIG volumes that are spread across the two hard drives (part of each drive is
concatenated, or added to, a portion of the second drive).
x One FAST volume that is striped across the two hard drives and one BIG volume
that is allocated the remaining capacity on both drives. The reversed
configuration—one BIG volume and one FAST volume—is also possible.
x One FAST volume that is striped across the two hard drives and one SAFE
volume that is allocated the remaining capacity (split between the volume and its
mirror twin). The reversed configuration—one
SAFE volume and one FAST
volume—is also possible.
x One BIG volume that is spread across the two hard drives (part of each drive is
concatenated, or added to, a portion of the second drive) and one
SAFE volume
that is allocated the remaining capacity (split between the volume and its mirror
twin).
