Chapter 2. Setup and Monitor
2.1 Setup Overview
To simplify the process of setup, DVPro is designed to support all of setup options from front panel LCD
and button operation. The default RAID level is RAID6 for highest reliability. To prevent malfunction,
parametners cannot be changed at normal operation mode. Critical parameters include number of drive,
capacity, and RAID mode should be set up before you started to work with the unit. Default parameter if
any is followed with “*” sign

2.3 Introduction of Parameters Setup
This section will explain the general parameters setup process.
To start with new configuration, the system has to enter Parameter Setup mode. Please press and hold
both “Mode”and “Select”buttons for more than 3 seconds while turning on power. The LCD should show
message as below indicating the system in Parameter Setup mode.

After a new configuration completed, hold down the Mode button at next power on at the same time for
system initialization. (Notice: this will initialize controller based on configured parameters. This action will
force failed drive or rebuilding status to become “Normal”. Please DO NOT do this if your system was in
degraded mode, and need to be recovered.) After power on, LCD should show its RAID mode and
“Normal”status.

Setup stripe width of each drive channel.
When the host issues a command, and the parity is to be
written, the command is divided up into two or more
operations.A relatively big stripe width is setup to reduce the
overhead of continuous operation.
Default
2 MB/DRIVE

BIOS CORPORATION
-15 -
The bigger size of stripe width, faster transfer speed can be
achieved for sequential read or write. Usually「2MB/ DRIVE」
setup will give a good performance but it depends on the host
application.

Recovery Rate Setup
RECOVER RATE

Recovery (Rebuild) operations utilize free time between host data access without interrupting the current
host application.
Therefore data read/write priority can be adjusted through different recovery rate setting.
User can choose the timing to execute recovery operations as below.
Parameter
Function
Memo
RECOVER
WAIT
TIME 0 Sec
Recovery request will be processed immediately between host
commands. Recovery will always be processed therefore host
access will be slow down. Select this mode if you want the
recovery have high priority.

DVT10B3

RECOVER
WAIT
TIME 0.1 Sec
Continuous host commands will be processed first. Recovery
operation will be taken care when the interval between host
commands longer than 0.1 sec. The following host command has
to wait till one recovery task completed except READ/WRITE or
READ Cache command which will be executed immediately.
RECOVER
WAIT
TIME 1 Sec
This can be used when host access are not concentrated.
The wait interval following the last host command is 1 sec. On this
mode, the recovery operation will not be processed if the host
commands are continuous with less than 1 sec internal.
RECOVER
WAIT

Usually this should not be used.
Probably this mode can be applied if there is very little host
access.
RECOVER
RATE

This is to assign the recovery time for 1GB capacity despite of

This parameter defines the timing of flushing cache contents into disks.
Parameter
Function
Memo
WRITE MODE
WAITING
Under this setting, the Write operation will not be acknowledged
as “Completed” till data is written into disks. This means no
caching is used during data write. The performance is slower
compared to 「WRITE MODE PENDING」mode. READ speed is
not affected.

After caching the first host WRITE, the cache content will only be
flushed into disk if there is more than 0.1 sec host idle or cache
threshold is met. When doing sequential writes, cache will be
filled by multiple write command and data can be written once to
save total write time.
Default
WRITE MODE
PENDING

Similar to PENDING 0.1 sec, the wait interval is one second.
Verify Mode Setup
VERIFY WAIT
READ aft WRITE
Verify Mode allows you to setup the action for ATA WRITE VERIFY command. “No Verify”will take
‘WRITE VERIFY’command as a simple ‘WRITE’without waiting verification to be completed.
Upon READ request after a WRITE command, “NO READ aft WRITE”, means to use cached content to
respond a READ command after WRITE. “READ aft WRITE”means cache data was disgarded and
controller has to read data from disk
Parameter
