2. DIP Switch and RAID Mode cross reference
User can configure any RAID mode as below by DIP switch and apply change by change mode
switch.
Dip Switch
RAID Mode 1 2 3
RAID 0(Single) ON ON ON
RAID 10 ON ON OFF
JBOD (Large) ON OFF ON
RAID 3 ON OFF OFF
Clone OFF ON ON
RAID 5 OFF ON OFF
Reserved OFF OFF ON
Normal (Single) OFF OFF OFF
Note: When DIP Switch is set to RAID 10 ----
*If you installed two HDD only, it is with RAID 1 mode
*If you installed four HDD, then, it is RAID 10 mode
2.1 RAID 0 for High Performance
RAID 0(or Stripe) is the segmentation of logically sequential data, such as a single file, so that
segments can be assigned to multiple hard disks in a round-robin fashion and thus written
concurrently. (if any one hard disk gets defective, information stored in this RAID 0 mode will be
invalid.)
Page 6

2.2 RAID 1 (Mirror) for High Security
RAID 1 (or Mirror) is the replication of data onto separate hard disks in real time to ensure
continuous availability. Take a RAID 1 system with two hard disks as an example, data in a hard
disk will be exactly the same as the data in another hard disk.
(Failure in a hard disk, Host controller still could read/write data. Users have to replace the
defective hard disk. 2350RES will enter identical-rebuild mode automatically)
2.3 Stripe + Mirror (RAID 10) for High Performance and High Security
2350RES could be configured to support Stripe and Mirror at the same time, i.e. RAID 10. Take
four hard drives RAID 10 as an example. Hard drive 0 and hard drive 1 could act as Mirror 1 and
hard drive 2 and hard drive 3 could act as Mirror 1 too. Then, 2350RES configures these two
Mirrors as Stripe.

2.4 Clone
This mode is useful especially when users would like to copy data from a hard drive to several
hard drives at the same time. Clone’s action is similar to RAID 1. However, all of the hard disks
will be the mirrors. For example, in a four hard drives Clone environment, data in each hard
drive will be same.
2.5 JBOD (Concatenating)
This mode is also named Concatenating. In this mode, 2350RES will concatenate all of the hard
drives into a single hard drive with larger capacity. For example, if three 500GB hard disks is
connected to 2350RES in concatenating mode, user will get a single hard disk with capacity of
1,500 GB.

2.6 Parity Protection
XOR engine in 2350RES generate parity block. In RAID 3 mode, Parity Block will be stored in the
same hard drive. While in RAID 5 mode, Parity Block will be spread over all of the different hard
drives.
2350JMR will also make use of same size disk space in each hard disk under RAID 3/5 condition.
( In RAID 3 or 5 mode, failure in a hard disk will cause ST-2350RES enter degraded-mode. Host
controller still could read/write data through 2350RES normally without knowing any defects.
Users have to replace the defective hard disk. 2350RES then will enter identical-rebuild mode
automatically.)
2.7 Normal Mode (Single)
Normal mode means all of the configured hard drives exist and 2350RES is not in rebuild
condition. User can see the original hard drives from the host which supports port multiplier
technology.
( Note: If the host does not support port multiplier, then you will find only one hard drive on
operating system. The RAID tool is useful in this case.)
