3.6.1 Volume Create Wizard
“Volume create wizard”
has smart policy. When the system is inserted with several
HDDs, “Volume create wizard” will list all possibilities and sizes in different RAID levels.
It will use all available HDDs for RAID level depending 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 selects the RAID
level, user may find that some HDDs are available (free status). This is the result of
smart policy designed in the iSCSI RAID subsystem. 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 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). With the wizard, it will do smarter check and find out the most efficient
way of using the HDDs. The wizard will only use 200G HDDs (Volume size is
200G*11=2200G), 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.
