maximum spaces on RAID levels 0/1/3/5/6/0+1. “Quick install” will occupy all
residual VG space for one UDV.
“Quick Install”
has a smarter policy. When the system is inserted with some
HDDs. “Quick Install” lists all possibilities and sizes in different RAID levels, it
will use all available HDD for RAID level depends on user’s choose. When
system has different sizes of HDDs, e.g., 8*200G and 8*80G, it lists all
possibilities and combinations in different RAID levels and different sizes.
After user sets the RAID level, user may find there are still some HDDs are
available (free status). The result is using smarter policy designed by
iStarUSA
.
It gives user:
1. Biggest capacity of RAID level for user to choose.
2. The fewest disk number for RAID level / volume size.
E.g., user chooses RAID 5 and the iStarUSA iSCSI Storage 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, we can 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
“Quick install”
and then choose the RAID level. After RAID
level is chosen, click “
”. Then it will link to next page.

Step 2:
Please select a LUN number. Access control of host would show as a
wildcard
“*”
, which means every host can access to this volume. In this page,
