3.6.1 Volume Create 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., 3*200G and 1*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 controller has 3*200G and 1*120G HDDs inserted.
If we use all 4 HDDs for a RAID 5, the maximum size of volume is 360G (120G*3).
By the wizard, it does a smart check and finds out the most efficient way of using
HDDs. The wizard only uses 200G HDDs (RAID5 Volume size is 200G*2=400G), the
volume size is bigger and fully uses HDD capacity.
Step 1: Select “Volume create wizard” and then choose the RAID level. After the
RAID level is chosen, click “
”. 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
“
”.
