Overview

Congratulations on your selection of the Accusys ACUTA 4/4S subsystem. The ACUTA 4/4S
is a high-performance and extremely flexible RAID subsystem. RAID (Redundant Array of
Independent/Inexpensive Disks) is a storage technology used to improve the processing
capabilities of a storage system, providing a combination of reliability and performance. The
ACUTA 4/4S is ideally suited for integration with databases, e-mail, web servers and imaging
systems.

The ACUTA 4/4S is the ultimate approach to a flexible RAID solution. It can manage three
different RAID levels (0, 0+1 and 5) and also offers the option of RAID 5+hot spare. You will
find detailed explanation on the features and suggested uses of these RAID levels later in this
chapter.

The ACUTA 4/4S subsystem features a user-friendly drive carrier design that lets you easily
install four drives. Each drive carrier supports a one-inch high 3.5-inch form factor drive.

Featuring intelligent online recovery , the ACUT A 4/4S lets you hot swap a failed drive: data will
automatically be rebuilt to the new drive without any system down time. The four drive design
allows also one drive to be designated a hot spare: if one of other drives fails, the ACUT A 4/4S
will seamlessly rebuild the failed drive’s data on the hot spare.

array should be identical models with the same firmware versions. RAIDs can
use any size drive, however the smallest drive will determine the size of the
array.

Introduction to RAID levels

The ACUTA 4/4S can support the following RAID levels: 0, 0+1 and 5 with the additional
option of RAID 5 + hot spare. Which is the right level for you? The answer depends on the
application it is used for.

RAID Leve l 0 of fers high transfer rates, and is ideal for large blocks of data where speed is of
importance. Computer Aided Design, Graphics, Scientific Computing, Image and Multimedia
applications are all good examples. If one drive in a RAID 0 array fails however, the data on
the whole array is lost.

RAID Level 0+1 combines mirroring and striping functions on a minimum of four hard disks.
Mirroring provides full redundancy and protects data in case of multiple drive failure (providing
that data on one of each mirrored pair of drives is intact).

RAID Level 5 arrays of fer high I/O transaction rates, and are the ideal choice when used with
on-line transaction processing applications, such as those used in banks, insurance
companies, hospitals, and all manner of office environments. These applications typically
perform large numbers of concurrent requests, each of which makes a small number of disk
accesses. If one drive in a RAID 5 array fails, the lost data can be rebuilt from data on the
functioning disks. The ACUTA 4/4S allows users to set one disk as a hot spare that will be
activated automatically to replace a failed disk.

Accusys Acuta User’s Manual

RAID 0

RAID 0 links each drive in the array as one huge drive. Storage capacity is determined by the
smallest drive in the array. That capacity is then applied to format all other drives in the array.
If using a 40 GB, 50GB, 60 GB, and 70 GB drive in a RAID 0 array, your system will see one
huge drive of 160 GB (40 GB×4).

RAID 0 offers double or more performance under sustained data transfers when one drive per
ATA port is used. In such a configuration, unlike SCSI, ATA drives are always available to the
system. SCSI requires more management of the SCSI bus. But RAID 0 without fault tolerance,
if one of disks in RAID 0 array group fails, the RAID crashed.

RAID 0: Striped disk array without fault tolerance
Characteristics: Recommended use:

 RAID 0 implements a striped disk array, the data

is broken down into blocks and each block is
written to a separate disk drive.

 I/O performance is greatly improved by spreading

the I/O load across many channels and drives.

 Fastest and most efficie nt ar ray ty p e but offers no

fault-tolerance.

 Storage capacity = (No. of disks) × (capacity of

smallest disk)

 If installed 40 GB, 50 GB, 60 GB and 70 GB,

configured as RAID 0, the RAID capacity will be
160 GB.

RAID 0+1

RAID 0+1 combines mirroring and striping functions on a minimum of four hard disks.
Mirroring provides full redundancy and protects data in case of multiple drive failure (providing
that data on one of each mirrored pair of drives is intact).

RAID 0+1: Combination of mirroring and striping
Characteristics:

 This configuration provides optimal speed and reliability.
 Requires even number of disks (minimum 4 disks)
 Storage capacity = 2 x capacity of smallest of disk

 If installed four drives each are 40 GB, 50 GB, 60 GB and 70 GB, configured as

RAID 0+1, the RAID capacity will be 80 GB.

RAID 5 and RAID 5+hot spare

RAID 5 uses a mathematical expression that compares data from three drives and calculates
a fourth piece of data called “parity” which is saved on a fourth drive. Should one of the drives
fail, parity data can be used to rebuild the failed data. Under RAID 5, parity data is stored
across all drives in the array. This maximizes the amount of storage capacity available from all
drives in the array while still providing data redundancy. RAID 5 requires at least three drives.
The ACUTA 4/4S allows users to set RAID 5 with three drives and the fourth drive as a “hot
spare” ready to be used for rebuilding data in case one of the other drives fails. This is RAID 5
+hot spare f unction.

RAID 5: Independent data disks with distributed parity blocks
Characteristics: Recommended use:

 Each entire data block is written on a data disk.

Parity for blocks in the same rank is generated

on Writes, recorded in a distributed location and

checked on Reads.

 Highest Read data transaction, medium Write

data transaction rate.

 Relatively low ratio of ECC (Parity) disks to data

disks means high efficiency (compared to other

RAID levels).

 Good aggregate transfer rate.
 Storage capacity = (No. of disks – 1) ×

(capacity of smallest disk)

 In RAID 5, installed drives each are 40 GB, 50

GB, 60 GB, 70 GB, the RAID capacity will be 120

GB.

 In RAID 5 + hot spare, installed 40 GB, 50 GB, 60

Setting RAID level

RAID level is set using the RAID level selector
on the rear panel of ACUTA 4/4S. The RAID
level selector consists of two switches. The four
possible combinations of switch position
correspond to the four available RAID settings:
0, 0+1, 5 and 5+spare.

If the RAID level is not matched between the
disk setting and the RAID level selector
setting, the LCD will display the following
two messages alternatively:

(1) “RAID level”

“Unmatched”
(2) “Current: Rx”
“Original: Rx”

Note: Current Rx means the RAID level setting

of RAID level selector

Original Rx means the RAID level setting

of current disks

For example:
Supposed the RAID level selector is R0, but the disk

setting detected from disks is R5, the LCD will
display the following two messages alternatively:

(1) "RAID Level"

"Unmatched”

2. Set the new RAID level using the RAID level selector

3. Remove all four disks

4. Power on ACUTA 4/4S

5. Install the four disks to start RAID initialization

Changing RAID level may lead to the loss of all data on the array.

Chapter 4 – Setting up an ar ray

Setting RAID 0

1. Ensure ACUTA 4/4S is turned off.

2. Move both selector switches 1 and 2 to ON

as shown.

Setting RAID 0+1

1. Ensure ACUTA 4/4S is turned off.
2 Move select or sw itch 1 t o ON and 2 to OFF

as shown

Setting RAID 5

1. Ensure ACUTA 4/4S is turned off .
2 Move both selector switch 1 and 2 to OFF.

Setting RAID 5+spare

1. Ensure ACUTA 4/4S is turned off.

2. Move selector switch 1 to OFF and 2 to ON.

Initially, in a RAID 5+spare array, the drive in the TOP drive carrier is
the hot spare and its status indicator will be shown amber for
notification.

In a RAID 0+1 array, disk 1 , 2 and disk 3 , 4 are two independent RAID
1group . This allows one disk from each separate R1 group to fail
simultaneously.

33

Accusys Acuta User’s Manual

Creating an array

To create (initialize) an array:

1. Ensure that four drives are installed.

2. Ensure that the RAID level selectors are

correctly positioned for the desired RAID
level.

3. Connect a power cable.

4. Turn on the power switch.

5. Install drives to begin initialization

ACUTA 4/4S will check the status of the installed drives. If all of four drives are brand new or
never been used in ACUTA 4/4S then the initialization of the des ired RAID level array will
begin automatically.

If any one of DISKs you installed has been used in ACUT A 4/4S before, then ACUTA 4/4S will
have a notification on LCD to remind if you really want to initialize a new RAID with previously
used DISK to prevent wrong operation caused DATA loss.

ACUT A 4/4S confirms with you that “Creat e New R AID” an d y ou can sele ct “Yes” by button to
re-create new RAID or “No” to retrieve existing RAID according to current drives

註解 [V11]: replaced the

Four drives should usually be installed for initialization to begin. If four
drives are not installed when the power is turned on, the alarm will
sound. A “RAID Fail” message will also display unless:

Ö RAID 5+hot spare has been set
Ö The bottom three drive carriers have drives installed.

In this case, the initialization of a RAID 5 array will take place.

The RAID capacity determined on the RAID level and the capacity of
drives you installed in ACUTA 4/4S , for an example:

If configuring as R5 and install 4 drives each of them are 10 GB, 20 GB,
30 GB, 40 GB to create an array then the t otal RAID capacity will be 3 0
GB.

A full list of LCD display messages is given in Appendix C

If system power is turned off midway through array initialization, the
process will continue from its point of interruption when power returns.

In a RAID 5+spare array, the disk in the TOP drive carrier is the hot
spare initially. And disk status indicator of the hot spare one will be
shown amber for notification. But after disk hot swapping, the hot spare
disk will be changed. For example: when hot swap disk 3 , then the top
disk (disk 1) will be auto-rebuilt. If you plug disk 3 afterward, disk 3 will
be the new hot spare disk, it’s no longer the TOP disk. It can be
recognized by disk status indicator.

Chapter 4 – Setting up an ar ray

Removing / replacing a drive

What if a disk fails?

If a disk drive fails, the disk status indicator of the disk carrier will ligh t red an d the a larm will
sound. When this happens, you should replace the failed IDE disk.

The failure or removal of a single drive in a RAID5 array will not lead to

failure of the array. The failure or removal of a single drive in a RAID0 array
will lead to loss of all data on the array and the entire array must be
re-initialized.

There is no need to immediately replace a failed disk in a RAID 5+spare

array. The hot spare disk will be brought on line automatically.

The alarm can be silenced by pressing the Enter / Mute button to the right of

the display.

Swapping drives

The hot swap function for RAID 5 arrays enables failed disks to be swapped while the array is
powered on. RAID rebuilding will be processed automatically in the background and the
ACUTA 4/4S RAID subsystem will record its progress. If the host system is shut down or
powered off abnormally, the ACUTA 4/4S RAID subsystem will continue the disk rebuilding
process after power is turned on again.

A hard disk in a RAID 5 array should not be replaced when the system is

turned off. Doing so may leads to loss of data. Always hot swap disks in a
RAID5 array.

Partitioning the array - Windows

The array must be partitioned before it can be used. To do this on a Windows operating
system:

1. Establish the array and connect to the host

computer following the instructions in the
preceding chapter. Make sure no error
messages are showing on the LCD display.

2. Turn on the host computer.

3. On the desktop, right click the My

Computer icon.

4. Select Manage. The Computer

Management dialog box appears.

5. In the Computer Management dialog box,

select Disk Management from the left hand
menu. The array will appear in the lower
right section of the dialog box as a disk
marked unallocated.

Other disks attached to the host machine,
such as the main drive of the machine, will
have an assigned letter (e.g. C:) for the
parts of the disk (partitions) that are
accessible to the operating system. These
are listed in the upper right part of the dialog
box. Y ou must partition the disk and make it
accessible to the operating system.

43

Accusys Acuta User’s Manual

6. Right click on the disk representing the

array and select Create Partition. Follow
the wizard to create one or more partitions
on the array.

7. When you have completed creating a

partition, the array will appear as a disk in
the disk management section of the
Computer Management dialog box.

Partitioning the array - Linux

The array must be partitioned before it can be used. To do this on a Linux operating system:

1. Establish the array and connect to the host

computer following the instructions in the
preceding chapter. Make sure no error
messages are showing on the LCD display.

2. Turn on the host computer.

3. Check to confirm the operating system has

detected the array: type “df”
The array will be listed as shown at a

temporary location (/tmp). The code given
the array depends on the host interface
type. Arrays connected through a USB or
IEEE 1394 interface will be assigned a
code sda (sdb, sdc etc.). Arrays
connected through a serial ATA interface
will be assigned a code hde (hdf, hdg etc.)
as in the example shown.

When you have confirmed that the array
has been detected:

44

Chapter 5 – Partitioning the array

4. Enter the command to format the disk

(array): fdisk /directory/device name (e.g.
fdisk /dev/hde).

5. When the disk is formatted, you should

partition the disk. Call up the help screen as
shown to identify the correct command to
add a partition.

6. Enter the command to add a partition (in

the example given, the command is “n.”)

7. Enter the command to create a primary

partition then enter the number of primary
partitions you wish to create.

8. Enter the command to create a Linux

second extended file system on the array.
In the example, the command is mke2fs
/directory/device (mke2fs /dev/hde).

9. Assign the array a location: Enter mount

/directory/device /location (mount
/dev/hde /tmp).

Partitioning the array – Mac OS X

The array must be partitioned before it can be used. To do this on a Mac operating system:

1. Establish the array and connect to the host

computer following the instructions in the
preceding chapter. Make sure no error
messages are showing on the LCD display.

2. Turn on the host computer.

3. When the array is detected by system, it will

be shown as an untitled device on desktop.

4. Executing Disk utility to begin partitioning

array, (Disk utility is located
Applications/Utilities). The Disk utility
dialog box appears, and the array will
appear in the left menu of window as an
untitled disk.

Other disks attached to the host machine,
such as main drive of the machine, will
have an assigned name for the parts of the
disk (partition) that are accessible to the
operating system. These are listed in the
left hand menu of dialog box. You must
partition the disk and make it accessible to
the operating syst e m.

5. Choosing ACUTA 4/4S by click in left menu

and click on tag “partition” to fill the name
and size of the array. The array could be
created to be a single volume or several
volumes, determined by intention of user.
Then click Partition, which located lower
right corner of dialog box.

6. The confirmation dialog will be pop out to

confirm again. Click Partition to continue
procedure.

46

Chapter 5 – Partitioning the array

7. The partition will then begin, and process is

been showing as creating partition mapin

If you encounter a problem while using the ACUTA 4/4S, check this section for help.

1. When I lock a drive carrier with a disk drive in place, the red disk activity indicator

turns on and an alarm beep sounds. Why?

Ö Make sure the IDE and power connectors of the DISK are connected firmly to their

counterparts inside the drive carrier.

Ö Ensure the DISK is set as single-master.
Ö Change the disk drive with a new one and try again.
Ö Exchange the top and bottom drive carriers and tr y again to determine if the carrier

itself is faulty.

Ö If all of the above steps f ail, contact your vendor.

2. How can I turn off the alarm beep sound when there is a hard disk failure?

Ö Unlock the drive carrier of the failed disk, or
Ö Press the mute button.

Q

3. I have connected the ACUTA 4/4S subsystem, but it does not appear in the

motherboard BIOS. Why?

Ö Ensure that an array is initialized completely.

4. Why does ACUTA 4/4S not recognize the DISKs?

Ö There may be an DISK jumper-setting problem. Make sure all drive jumpers are set

to "Single-master". Please refer to FAQ 1.

5. How should I react to disk failure?

Ö For a RAID 5/RAID 0+1 array, you should replace the failed disk. Data rebuilding will

then begin.

Ö For a RAID 5+hot spare array , data will be rebuilt automatically to the hot spare disk.

There is no need to immediately replace the failed drive.

Ö The capacity of new DISK you installed must equal or larger than the smallest DISK

in ACUTA 4/4S. Othe rwise, it will be rejected b y ACUTA 4/4S, though it has no any
damage.

48

Appendix A – FAQ

6. How should I react to an DISK failure while creating a RAID 5?

Ö Replace the failed DISK with another of equal or larger capacity. The array will

re-initialize from starting.

7. If I only have two or three DISKs, can I create a RAID?

Ö 2 DISKs : No. ACUTA 4/4S need at least 3 disks to configure R5+hot spare
Ö 3 DISKs :Yes, but you can only choose R5+hot spare. The three DISKs must be

installed in the bottom three disk carriers with the top layer – the hot spare location,
left empty.

8. Why does the display read “unmatched”?

Ö The RAID level selector is not set to the level of the existing array. Please choose

one of the following options :

Supposed the RAID level selector is R0, but the disk setting detected from disks is R5.
(1) Shut down ACUTA 4/4S and tune the RAID level selector to R5.

or (2) Re-plug the four disks and re-create the Array to R0 (But data in the R5 disks will

be lost due to the destructive init )

9. If I really want to re-create a new RAID. How should I do?

Ö Remove all disks.
Ö Power off ACUTA 4/4S, set up RAID level by selector switch than power on ACUTA

4/4S.

Ö Plug in all of disks to initialize new RAID.
Ö If you use previous disks, ACUT A 4/4S will show a message “Create New RAID?” to

confirm with you if you really want to create a new RAID. Please choose “Yes” by
right button, the initialization will then begin.

Ö Please notice that the procedure will erase all data of the four disks.

10. The host computer cannot detect ACUTA 4/4S. What should I do?

Ö Make sure the host interface connection cable is attached securely to ports on

ACUT A 4/4S and the host and is not damaged.

Ö Check the display for error messages.

11. A disk has failed. What should I do?

Ö Swap the failed disk with one of the other three disks and turn on. If the same disk

fails, replace the disk. If the failure reappears at the same drive carrier, either the

49

Accusys Acuta User’s Manual

drive carrier or ACUTA 4/4S is faulty. Perform the next step.

Ö Swap the position of the drive carrier that failed twice and turn on. If the same drive

carrier fails, replace it. If the failure reappears at the same drive carrier slot, ACUTA
4/4S is faulty. Perform the next step.

Ö ACUTA 4/4S appears to have an internal malfunction. Consults your dealer.

12. Two disks have failed. What should I do?

Ö Swap the positions of the failed disks with the remaining two disks. If the same disks

fail, replace them. If the failures reappear at the same drive carriers, either the drive
carriers or ACUTA 4/4S is faulty. Perform the next step.

Ö Swap the position of the drive carriers that failed twice with the working drive carriers

and turn on. If the same drive carriers fail, replace them. If the failures reappear at the
same drive carrier slots, ACUTA 4/4S is faulty. Perform the next step.

Ö ACUTA 4/4S appears to have an internal malfunction. Consult your dealer.

13. Three disks have failed. What should I do?

Ö Swap the single functioning disks with each of the failed disks in turn. If the

functioning disk continues to function at its new location, the original disk was faulty
and should be replaced. If the functioning disk does not function at any of the three
other locations, the drive carriers for those location or ACUTA 4/4S is faulty. Perform
the next step.

Ö Swap the functioning drive carrier in the same way to find out if the drive carriers or

ACUT A 4/4S. Replace any malfunctioning drive carriers.

Ö Consult your dealer if ACUTA 4/4S appears to be faulty.

14. Four disks have failed. What should I do?

Ö If four disks have failed, you will need to use another disk that you know is functioning.

Use this disk in the same way as outlined in the previous answer to find out if the
malfunction is with the original disks, the drive carriers or ACUTA 4/4S.

16. Why can’t I use ACUTA 4/4S with Windows 98 on a USB2.0 host interface ?

Ö We recommend user NOT to use Windows 98 because Windows 98 is too old and

not compatible with many cards. Please refer to Chapter 4, the OS compatible list
table.

17. Under Fire-wire connection, ACUTA 4/4S is not detected by MAC G5 if ACUT A 4/4S

is powered on before MAC G5 is powered on ?

Ö The problem is due to the Fire-wire chip manufacturer F/W driver issue. T o solve this

issue, you can choose either :

1. Always power on MAC G5 before power on ACUTA 4/4S

2. Unplug the Fire-wire connector from MAC G5 then re-plug it again.

18. Under Windows 2K/XP/2003 OS with 2 partitions (NTFS / FAT32), the FAT32

partition may crash after running for days.

Ö The problem is due to the Fire-wire/USB chip manufacturer F/W driver issue. To

solve this problem, you can only use one file system for all the partitions.

Array

See Disk Array.

Array Management Software

The body of software that provides common control and management for a disk array. Array
Management Software most often executes in a disk controller or intelligent host bus adapter,
but may also execute in a host computer. When it executes in a disk controller or adapter, Array
Management Software is often referred to as Firmware.

Cache

Controller memory used to speed up data transfer to and from a disk.

Disk Array

A collection of disks from one or more commonly accessible disk controllers , combined with a
body of Array Management Software. Array Management Software controls the disks and
presents them to the array operating environment as one or more virtual disks.

Firmware

See Array Management Software.

Host Computer

Any computer system to which disks are directly attached and accessible for I/O. Mainframes,
and servers, as well as workstations and personal computers, can all be considered host
computers in the context of this manual, as long as they have disks attached to them.

IEEE 1394

IEEE 1394 is a standard for transmitting data between devices at high speed - up to 400 Mbps
(in 1394a) and 800 Mbps (in 1394b). IEEE 1394 also supports isochronously data transf er,
which is ideal if you need to transfer large amounts of data in real time. The standard is also
known as FireWire and i.Link. A single port can be used to connect up to 63 external devices.

54

Appendix B – Glossary

Parallel ATA (Parallel Advanced Technology Attachment)

Formerly referred to simply as ATA, now known as parallel ATA to differentiate it from Serial
ATA. Various versions exist, including ATA (also call e d IDE), A TA-2 (Fast ATA or Enhanced
IDE /EIDE) and Ultra ATA (Ultra DMA).

Parity

Parity information is redundancy information calculated from actual data values. If an y single
piece of data is lost, the data remaining a nd the parity information can be used together to
compute the lost data. Parity information can either be stored on a separate, dedicated drive, or
be mixed with the data across all the drives in the array.

RAID (Redundant Array of Independent / Inexpensive Disks)

A disk array in which part of the storage capacity is used to store redundant information about
user data stored on the remainder of the storage capacity. The redundant information enables
regeneration of user data in the event that one of the array member disks or the access path to
it fails. See Parity. Different RAID levels offer different data throughput speeds and fault
tolerance (data redundancy). RAID 0 does not feature redundant information but is nonetheless
considered a special type of RAID.

SCSI (Small Computer System Interface)

An interface standard for attaching external dev ices t o computers . SCSI interfaces provide for
data transmission at up to 80 Mbps. You can attach many devices to a single SCSI port.

Serial ATA (Serial Advanced Technology Attachment)

Serial ATA (often abbreviated as SATA or S-ATA) is a advance on the commonly used Parallel
ATA interface for data storage devices. Serial ATA allows data transfer up to 1.5 Gbps. It has
an additional advantage parallel ATA in that cables are thin ner, so airflow within computer
cases is less impeded, and can extend to one meter in length (against only 40 cm for parallel
ATA).

USB (Universal Serial Bus)

USB is a standard for transmitting data between devices at high speed - up to 480 Mbps for
USB 2.0. USB supports hot swapping of devices. USB 2.0 is an extension of the original USB

1.1 standard and uses the same connectors. A single port can be used to connect up to 127
external devices.

The ACUTA 4/4S is shipped with firmware installed. You may however wish to install new or
upgraded editions of the firmware. Ask your vendor about the latest firmware ed ition or refer

a host PC with third party communication software, such as HyperTerminal, that supports
ANSI terminal emulation. Other terminal programs may be used in place of HyperTerminal to
communicate with ACUTA 4/4S. Howe ver, the setup process for other terminal so ftware may
differ from that outlined in this chapter.
