3.2.2 Volume creation wizard
“Volume create wizard” has a smarter policy. When the system is inserted with
some HDDs. “Volume create wizard” lists all possibilities and sizes in different RAID
levels, it will use all available HDDs for RAID level depends on which user chooses.
When system has different sizes of HDDs, e.g., 8*200G and 8*80G, it lists all
possibilities and combination in different RAID level and different sizes. After user
chooses RAID level, user may find that some HDDs are available (free status). The
result is using smarter policy. It gives user:
1. Biggest capacity of RAID level for user to choose and,
2. The fewest disk number for RAID level / volume size.
E.g., user chooses RAID 5 and the system has 12*200G + 4*80G HDDs inserted. If
we use all 16 HDDs for a RAID 5, and then the maximum size of volume is 1200G
(80G*15). By the wizard, we do smarter check and find out the most efficient way of
using HDDs. The wizard only uses 200G HDDs (Volume size is 200G*11=2200G),
the volume size is bigger and fully uses HDD capacity.
Step 1: Select “/ Volume configuration / Volume create wizard” and then choose
the RAID level. After the RAID level is chosen, click “Next”. Then it will link to next
page.

Step 2: Please select the combination of the RG capacity, or “Use default
algorithm” for maximum RG capacity. After RG size is chosen, click “Next”.
