5 Advanced Configuration
This section describes how to use the Advanced Configuration Wizard to apply more than one storage policy to
volumes on the SiI 4726 Storage Appliance.
Why Advanced Configuration?
The Basic Configuration Wizard provides six predefined storage policies to quickly configure the SiI 4726
Storage Appliance. Each predefined storage policy allocates the maximum system capacity to the selected
storage policy.
Using the Advanced Configuration Wizard, you can configure up to ten volumes - each with different storage
policies and capacities. This flexibility provides numerous combinations of performance, redundancy, and
capacity to meet your business requirements. For example:
• For applications that produce critical data, redundancy is important. You could use the Basic
Configuration Wizard to implement the predefined SAFE, SAFE and FAST, or SAFE and BIG
storage policy. This format would allocate all hard disk drives to SAFE volumes. This may be
excessive for your needs. Use the Advanced Configuration Wizard to create additional volumes
and allocate capacity more efficiently.
• For applications that require hundreds of gigabytes of storage space, the added redundancy of a
SAFE configuration’s Hot Spare may not be an acceptable luxury. Use the Advanced
Configuration Wizard to create multiple volumes that make use of every gigabyte of available
space.
These are just a few of the possible combinations of storage policy and capacity allocations that you can create
with the Advanced Configuration Wizard. Experiment with other combinations to allocate the total system
capacity to meet your needs.
