1.3 RAID Mode Explanation

● Any change of RAID mode will cause data rebuild and data lost.

① RAID MODE 6

② RAID MODE 0

③ RAID MODE 3

④ RAID MODE 5

Data

Drive

Parity Data Drive

Data and parity are equally distribute d among 6 drives

The most bottom drive is used for Parity It allows one drive failure while data is accessing. The data residing in failed drive can be generated from the rest of 5 drives

Data and Parity are distributed among 6 HDDs. Since there is no assigned disk for parity, each drive shares the same loading in data access.

Data

Drive

All drives are used for data recording Data is segmented and equally distributed among 6 drives. All 6 drives will be accessed while data is read or written. The mode provides the highest performance among all others.

At the same time, if one drive failed, the whole data will be lost.

Data and Parity are divided by six portions

Comparing with RAID- 5 dual parity is applied providing even higher reliability Allow up to two drives failure but also scarify capacity of two drives

CAUTION

－ 14 －

⑤ RAID MODE 1

⑥ RAID 0-2 DRIVE MODE

⑦ RAID 1 - 3 DRIVE MODE

⑧ RAID MODE 10

⑨SINGLE DRIVE MODE

Data Drive

Only one drive is used. Data cannot be recovered if the drive is failed

In general, Data at RAID 1 is written to two drives at the same

time and read from one or both of drives.

Capacity is half the of the total physical disk capacity

Only two drives RAID-0 mode. (The rest of four drives cannot be used) There is no parity so the data cannot be recovered if any of drive fault.

Data Drive

Three drive mirroring mode. Similar to RAID MODE1, Data is written to all of three drives and read only from one or two drives. Even two drives failed, the data can still be accessible. The rest of three drives cannot be used.

It is the combination of RAID-0 and RAID-1. Performance and security can be raised. Stripe across mirrored Drive 0, 1 and Drive 2, 3

Capacity is equal to 2 drives capacity. Data can be accessed even one of both mirrored pair drives failed. The rest of two drives cannot be used.

2.2 Overview of Setup method

To simplify the procedure of setup, BR256 is designed to support all of setup options by front panel LCD. The default configuration and parameters are default for RAID-6 mode. BR256 is supposed to up and run without changing default setting unless a special configuration needed. To prevent malfunction, BR256 setting cannot be changed during operation

2.3 Setup display navigation

This section will go through the parameters setup displayed on LCD screen.

If this is first time to power on the unit, an Initialization Procedure should be done first. When powering up the BR256 unit, press and hold the Mode button (besides LCD) at power on. (Notice: this will clean up the system status and parameters recorded in non-volatile memory.)

（Without performing initialization, the LCD display might show「RAID-x ONE DRIVE DOWN」､「SYSTEM

DOWN」indicating the status of last time. A normal display with drives properly populated will look like

RAID-6

Recovery operations utilize time between host data access without interrupting the current job. Therefore data read/write can be continued without interruption. 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.

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

TIME 10 Sec

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

RECOVER

RATE 2Min./GB 5Min./GB

10Min./GB 20Min./GB

This is to assign a fixed recovery time for 1GB capacity despite of interval to wait between host commands.

Yet there is possibility that 5Min./GB cannot be finished in time

Default 128MB

● Write Cache Mode Setup

WRITE ALL

PENDING 0.1Sec

The controller needs more time than writing to single drive to generate parity while doing RAID-3/5/6 WRITE. Therefore Write Cache is enabled in such situation. This parameter defines the timing to wait before starting to move 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.

WRITE MODE

BUFFERD

Write command is acknowledged as “Completed” right after data

written into cache, and cached data starts to be moved into disks at the same time.

WRITE MODE

PENDING

0.1Sec

After finishing a host command, this mode will wait 0.1 seconds and start to write data before the next command. When doing sequential writes, cache will be filled by multiple write command and data can be written once to save total write time.

WRITE MODE

PENDING

1 Sec

Similar to PENDING 0.1 sec, the wait interval is one second.

WRITE ALL

Verify] mode. Also, you can choose to read the data off the disk after it has been written from cache when a read request takes place [READ aft WRITE], or you can choose not to verify it at all after the write [NO READ aft WRT]

Parameter

Function

Memo

VERIFY

WAIT

The Write command cannot be completed at the time data written into cache. It has to wait till Write and Verification command completed.

Default

NO VERIFY

There is no verification operation when doing Write & Verify under such mode. A simple write will be executed. Verify command is not affected by this setting.

READ aft

WRITE

Instead of Verify command, sometimes READ command usually follows a series of Write command to compare and verify the written data. It is meaningless if cache data is used upon READ command received. This parameter is to clean up cache data after WRITE, and force data to be read from disks when READ command is received.

Default

NO READ aft

WRT

This mode assumes write operation can be continued when data is into cache before moving to disk. And also it assume there is no more than one drive failed at the same time under RAID-3/5 setting. The data written into cache becomes effective immediately.

Force Reset（Initialization）

If you force reset by powering on while holding down the MODE switch, all active drives will be returned to their normal state. If all drives are active, the system will return to NORMAL. This should be applied when it is the first time to initialize the disk array

At this time, the actual health of the disks will not be verified. All drives are assumed to be healthy. If you would like to force reset right after [ONE DOWN] or [SYSTEM DOWN] reported, please follow instruction of qualified technical support staff. While the array is in「ONE DOWN」or「SYSTEM DOWN」, if you operate incorrectly, there might be chance to cause data corruption.

Force Reset（Transition from「SYSTEM DOWN」）

If there is a damaged drive, contact our technical support staff for further assistance.

Below is an example of typical operation

● After removing the damaged drive, hold the Mode switch at powering on and force reset the machine. It will set up a most appropriate state for the unit

・DRIVE FAIL LED still on, means that drive was the first to go down. Please remove it first ・ DRIVE FAIL LED blinking, that drive went down afterwards so keep it installed. Hold down

the Mode switch and power cycle the machine for possible recovery

・ In a RAID-3/5 configuration, it will go back to ONE DRIVE DOWN status.

● It is sometimes possible to access the system even during SYSTEM DOWN.

Under such state, please try to access and backup data out of the array

● If nothing’s working, replace all the drives you think might be bad, and start over with a force reset (Initialization).

Parity Drive

● Under RAID-3 configuration, Data drives and Parity drive are arranged in a sequential order. Parity drive follows the last of data drive.
