7 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.
