RAID Settings Descriptions
SINGLE MODE
Array will show up as two independent drives. This function
can be used if only if two different brands and/or capacities
of HDDs (Hard Disk Drives) are installed.
SPANNING MODE
RAID 0 (Striping)
Two HDDs will show up as a single drive with the combined
capacity of both drives. Spanning writes data sequentially
across two drives.
Two HDDs will show up as a single drive with the combined
capacity of both drives. Speed and performance increase.
The two HDDs “stripe" data across the two drives. This splits
each piece of Data across both HDDs in segments in a way
that speeds up reading and writing times. However, RAID 0
does not offer any data protection: if one drive fails or is
damaged, all data can be lost.
RAID 1 (Mirroring)
The RAID controller creates an extra copy (or mirror) of data
on the two drives. Only a single drive will show up on your
computer, and it will have the capacity of a single drive.
Data is protected from the failure of one drive. If one drive
fails, replace it with an identical drive and the data rebuilds
automatically.
Using this mode requires 2 identical HDDs; the two drives
must be the same capacity, brand and model number.

After the drive is completely uninitialized, turn off your drive. Set the CADA-
U32 on its side. Remove the cover by removing the screws on the bottom of
unit. The screws only need to be removed on the "top" side. The "top" side is
the side to which the power switch (on the back of the unit) is closest. Once
the screws are removed, insert the screw-driver into the holes left by the
screws and push upward to release the top cover.

8.
Decide which RAID setting
you want, and, following
the diagram to the right,
move the jumper shunts to
cover the appropriate pins.
(On the diagram to the
right, grey indicates that a
pin is covered; white
indicates an uncovered pin.)
The jumper shunts may be
moved by gently pulling
them upwards (vertically)
until they are free, then
pushing them downwards
onto the appropriate two
pins.
NOTE: If switching from any mode to RAID 1 mode, you must first configure
the jumper block to “Single” mode. Then connect your drive to your
computer, turn on your drive, and repeat step 5 (un-initialization) on BOTH
drives (in single mode, the array will show up as two drives). Then you may
continue again from Step 6 and configure the jumper block to RAID 1.
NOTE: When placing the jumper shunts, make sure they are oriented
along the longest axis of the drive. For example, if you want RAID 1
mode, one jumper shunt would cover pins 1 and 2, and another jumper shunt
would cover pins 4 and 5, as opposed to one jumper shunt covering pins 1
and 4, and another jumper shunt covering pins 2 and 5.
Fig. A (below) shows how the [uncovered] jumper pins are numbered. The
black arrow points to the back of the drive.

Your jumper block should look something like this when finished changing
settings. Shown is RAID 0 (striping) with pins 1, 2, 5, and 6 covered. Note
that the jumper shunts are oriented along the longest axis of the drive.
10. Replace the cover of your CADA-U32. With your disk array connected to your
computer and turned on, initialize and format your new volume. If you need
help initializing and formatting your drive, see the Formatting Guide, located
on our Downloads page: www.cavalrystorage.com/su_download.htm
11. After initializing and formatting, your drive will be ready to use!
