g Operating Instruction
A disadvantage is that you need at least four hard drives and
you can only make use of 50% of the entire storage capacity.
To set up a RAID 0+1 array, proceed as follows:
1. Once you have properly installed the card, restart the
computer.
2. Once the controller BIOS is displayed after rebooting, press
the key combination CTRL+J, in order to access the card
BIOS.
3. In the controller BIOS, select the option "Create RAID Disk
Drive" (create a RAID hard drive array).
4. Give the RAID array a name of your choosing. Note that the
name cannot have more than 16 characters and that you may
not use special characters.
5. Using the up and down arrow keys, position the RAID level
at "01-Stripe+Mirror" (Mirroring and Interconnection) and
then press ENTER.
6. Using the up and down arrow keys, select the required
hard drives (if you have connected 4 hard drives
to the controller, these will be automatically selected) and
highlight these using the space bar. When you have
highlighted the required drives, press ENTER.
7. In the next step, you must use the up and down arrow keys
to select one of the "block sizes" (data block) from the
following list, 4 kB, 8 kB, 16 kB, 32 kB, 64 kB or 128 kB, and
press ENTER.
8. The maximum capacity is set by default. If you want to use a
lower capacity, enter this in the field marked "Size:". Note
that the remaining storage space will remain unused.
9. As a precaution, you will be asked by the controller
BIOS whether you wish to create the RAID array based on
the information you have already given (Create RAID on the
selected HDD (Y/N)?). Press ENTER for Yes. (Caution:
when you press ENTER, all data on the selected hard
drives will be irrevocably deleted.)
10. As a last step, select the menu item "Save and Exit Setup"
and then press ENTER. Answer the query, "Save to
Disk & Exit (Y/N)?" by pressing ENTER for Yes,
in order to exit the controller BIOS.
11. Now configure the RAID array from within your operating
system as described in the system handbook.
JBOD (Connecting several hard drives together)
Note: JBOD requires at least two hard drives. Ideally, you
should use two or more identical hard drives from the same
manufacturer.
What is JBOD?
Put simply, RAID level JBOD combines all selected hard drives
in one unit. Your operating system does not notice that, for
example, you have connected three hard drives of varying
capacity to the controller. As far as the system is concerned,
there is only one drive, using the total capacity of all hard drives.
A disadvantage of this is that, in the event of the malfunction
of one hard drive, you lose all the data on this drive. Also, the
maximum data throughput is restricted to the slowest hard drive
in this array.
1. Once you have properly installed the card, restart the
computer.
2. As soon as the controller BIOS is displayed after rebooting,
press the key combination CTRL+J, in order to access the
card BIOS.
3. In the controller BIOS, select the option "Create RAID Disk
Drive" (create a RAID hard drive array).
4. Give the RAID array a name of your choosing. Note that the
name cannot have more than 16 characters and that you
may not use special characters.
5. In the next menu screen, using the up and down arrow keys,
position the RAID level at "JBOD-Concatenate"
(concatenation / interconnection) and press ENTER.
6. Using the up and down arrow keys, select the required
hard drives, highlight these using the space bar and then
press ENTER.
7. The maximum capacity is set by default. If you want to use a
lower capacity, enter this in the field marked "Size:". Note
that the remaining storage space will remain unused.
8. As a precaution, you will be asked by the controller
BIOS whether you wish to create the RAID array based on
the information you have already given (Create RAID on the
selected HDD (Y/N)?). Press ENTER for Yes.
(Caution: when you press ENTER, all data on the
selected hard drives will be irrevocably deleted.)
9. As a last step, select the menu item "Save and Exit Setup"
and then press ENTER. Answer the query, "Save to
Disk & Exit (Y/N)?" by pressing ENTER key for Yes,
in order to exit the controller BIOS.
10. Now configure the RAID array from within your operating
system as described in the system handbook.
Deleting the RAID array:
To delete the RAID array you have previously configured,
proceed as follows.
1. As soon as the controller BIOS is displayed after rebooting,
press the key combination CTRL+J, in order to access the
card BIOS.
2. In the controller BIOS, select the option "Delete RAID
Disk Drive".
3. Your existing RAID array is highlighted automatically. Select
the array by pressing the space bar.
4. Delete the RAID array by pressing the DEL key or ENTF key.
5. A security query appears, asking whether you really want to
delete the RAID array. "ALL DATA ON THE RAID WILL BE
LOST!! ARE YOU SURE YOU WANT TO DELETE (Y/N)?" Press
the Y key (for Yes) if you are absolutely sure.
Note: All data saved in the RAID array will be irrevocably
deleted.
