CHAPTER 1. INTRODUCTION
RAID CONCEPTS
The need to ensure continuous access to critical computer data is essential today in such a highly
competitive business environment. Data loss and server downtime caused by drive failure often
results in lost productivity, decreased profitability, and can differentiate between success and
failure in a competitive business environment. RAID (Redundant Array of Independent Drives)
addresses this problem. The Benefits of RAID include:
Availability
Provides fault-tolerance by mirroring or parity operation. If any single disk drive in the RAID
fails, the RAID still continues to function without loss of data.
Capacity
Provides disk spanning by weaving all connected drives into one single volume.
Performance
Increases disk access speed by breaking data into several blocks when reading / writing to several
drives in parallel. With RAID, storage speed increases as more drives are added.
1.1.1 RAID LEVELS
The SurfRAID LC16 supports RAID Levels 0, 1, 3, 5 & 0+1. Each RAID level offers a different
performance, functionality and fault tolerance, depending on the application that will be used.
The following is a brief explanation of each RAID level. Before configuring the SurfRAID LC16, be
sure to know which RAID level is best suited for your application.
1.1.1.1 Striping (RAID 0)
Striping refers to the storing of data across multiple drives in a drive group. If there are three
drives in a drive group then the subsequent data will be stored across all three drives. This creates a very high performance virtual disk with the capacity equal to the combined capacity of the
installed disks. RAID Level 0 provides high availability and very high performances for both
read and write operations. However, no redundant parity is generated for protection against disk
failure.

1.1.1.2 Mirroring (RAID 1)
Mirroring refers to the replication of data on two or more drives. Each drive contains a mirror
image of the data on the primary drive. Virtual disk space equals to capacity of the smallest
installed disk drive. Mirroring causes operational overhead resulting in lower performance for
write operations, however it does provide the highest data reliability among RAID Levels 0 to 5
with very high performance for read intensive operations.

1.1.1.3 Striping with Dedicated Parity (RAID 3)
Performs Block Striping with Dedicated Parity. One drive member is dedicated to storing the
parity data. When a drive member fails, the controller can recover / regenerate the lost data of the
failed drive from the dedicated parity drive.

Striping with Parity is a method of storing data striped across multiple drives like RAID 0 but
with parity (redundant data calculated by XOR logic used to reproduce data in case of lost data)
also striped across the drives. RAID Level 5, which offers a very high data redundancy, availability and performance.

3.2.1 Monitor Utility
The SurfRAID LC16 control panel allows exploration of all configurable features. However, the small
form factor of the control panel only allows a small LCD display output. A limited amount of information
can be displayed at a given time on the LCD display.
The monitor utility displays all information on a larger terminal screen via a serial interface. The
monitor utility is identical to the LCD display, where it displays the basic self-diagnostic, operation, and configuration information. However, it allows the Configuration Menu to be displayed
using a graphical user interface. Additionally, it displays more detailed error, warning, and status
messages, impractical to display on the front control panel LCD.

The Configuration Menu is provided to help facilitate and assist configuring the SurfRAID LC16 RAID
subsystem. The SurfRAID LC16 has to disconnect from the host system when running the Configura-
tion Menu.
The main menu consists of seven categories. Each category is used to configure a different part
of the SurfRAID LC16 subsystem. The following shows the main menu categories. Each category has
sub-menus and options. In the following sections, the menu hierarchy will be described in detail.

3.3.2.2 SCSI / Fibre Params MENU
The SCSI / Fibre Params menu configures the SCSI/Fibre portion of the SurfRAID LC16 subsystem. The
SCSI ID and the termination must be set to avoid causing a conflict with the SCSI adapter or other
SCSI device daisy chained with the SurfRAID LC16. Command Tag Queuing is a function that allows a
SCSI device to queue multiple requests without having to serialize the operations. This frees the controller to process requests in whatever order is convenient, instead of blindly processing and acknowledging
each disk operation before starting the next. This allows the SurfRAID LC16 to efficiently handle multithreaded applications that issue multiple disk commands.

APPENDIX A. TROUBLESHOOTING AND ERROR MESSAGES
1. Troubleshooting
A. SurfRAID LC16.160S
Problem: SurfRAID LC16 is not properly identified by the SCSI adapter during the initialization of you
computer system.
Possible Cause: The SCSI ID set for the SurfRAID LC16 is used by another SCSI device attached
to the same SCSI adapter.
Fix: Through the Configuration Mode select SCSI Params, then Set SCSI ID, and specify a
different SCSI ID. Also, most SCSI host adapters provide an on-board ROM BIOS, or software
utility, that displays the devices attached and their SCSI ID. Disconnect the SurfRAID LC16 from the
SCSI host adapter and during the system boot, or by running the utility, note the SCSI ID’s already in
use. This will select a SCSI ID for the SurfRAID LC16.
Problem: The SurfRAID LC16 is identified at all SCSI ID’s.
Possible Cause: The SCSI ID set for the SurfRAID LC16 is identical to the reserved SCSI ID used
by the SCSI adapter in your computer system.
Fix: Use the Configuration Mode to configure the SurfRAID LC16 for a different SCSI ID. Remember
the majority of SCSI host adapter reserves SCSI ID 7 for the adapter ID.
Problem: The SurfRAID LC16 is not detected by the SCSI host adapter.
Possible Cause: Incorrect termination in a daisy chain configuration or a loose cable in a stand-
alone configuration.
Fix: In a daisy chain configuration verify only the SCSI host adapter and the last SCSI device is
terminated. To change the termination settings of the SurfRAID LC16 use the SCSI Params menu and
SCSI Termination option to enable or disable termination.
A. SurfRAID LC16.200F
Problem: SurfRAID LC16 is not properly identified by the FC-AL adapter during the initialization of
your computer system.
Possible Cause: The FC-AL ID set for the SurfRAID LC16 is used by another device attached to the
same FC-AL adapter.
Fix: Through the Configuration Mode select Interf Params, then Set FC-AL ID, and specify a
different FC-AL ID. Also, most FC-AL host adapters provide an on-board ROM BIOS, or software
utility, that displays the devices attached and their FC-AL ID. Disconnect the SurfRAID LC16 from the
FC-AL adapter and during the system boot, or by running the utility, note the FC-AL ID’s already in
use. This will select a ID for the SurfRAID LC16.
Problem: The SurfRAID LC16 is identified at all FC-AL ID’s.

Possible Cause: The ID set for the SurfRAID LC16 is identical to the reserved ID used by the FC-AL
adapter in your computer system.
Fix: Use the Configuration Mode to configure the SurfRAID LC16 for a different FC-AL ID.
A. SurfRAID LC16.160S & SurfRAID LC16.200F
Problem: Unable to access the SurfRAID LC16 after the operating system boots up.
Possible Cause: The SurfRAID LC16 is not configured.
Fix: Make sure the SurfRAID LC16 is configured for a RAID level. If no RAID level is configured the
operating system will not detect the SurfRAID LC16 as a disk drive.
Problem: Unable to access the Configuration Mode using the remote terminal interface.
Possible Cause: The terminal communications settings are not matching the settings of the SurfRAID
LC16 RS-232 interface.
Fix: The default settings for the RS-232 port are 19200 Baud rate, 8 Data bits, 1 Stop bit, No
Parity, and XON/XOFF Flow control. Make sure the terminal is configured for these settings. If
the settings were changed during Configuration Mode verify the settings of the SurfRAID LC16 in the
RS-232 Params, Terminal option and change the terminal settings accordingly.
Problem: The front panel LCD displays alternating “Zz” characters.
Cause: These characters are displayed when the cache is full with write request’s data that have
not been processed. It will halt requests from the host to flush the data in the cache.
Fix: None needed.
Problem: The front panel LCD displays alternating “Ww” characters.
Cause: These characters are displayed to indicate the write requests in the cache are being
processed. When these characters are displayed, the SurfRAID LC16 will halt requests from the host
(see above).
Fix: Make sure the “WRITE BUFFER” option of the “RAID Params” menu is enabled. In
addition, more cache memory may be required. By increasing the cache memory the write buffer
space increases and will be able to handle the higher write requests.
Problem: Unable to send a Page or FAX using the modem port.
Possible Cause: The Page and Fax options are not enabled.
Fix: Go to the Configuration Mode and enable Page and FAX notification via the System Params
menu option.

APPENDIX D. GLOSSARY
Array Management Software, Firmware
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.
Disk Array
A collection of disks from one or more commonly accessible disk subsystems, combined with a
body of Array Management Software. Array Management Software controls the disks and presents them to the array’s operating environment as one or more virtual disks.
Disk Striping
Data distributed across all the disks in the array. There is no redundant information generated or
stored.
Disk Mirroring
Data is duplicated on different sets of disks in the array.
FC-AL
Fibre Channel Arbitrated Loop
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 book, as long as they have disks attached to them.
Hot Spare
The substitution of a replacement unit in a disk system for defective one, where the substitution
can be performed while the subsystem is running.
Hot Swap
The substitution of a replacement unit in a disk subsystem for a defective one, where the substitution can be performed by the subsystem itself while it continues to perform its normal function.
Hot Swaps do not require human intervention (i.e., hot spare)
Member Disks
Disk channels configured for a particular RAID Level. Member disks are identified by a status of “0”
displayed on the front panel LCD.
Mirroring
A form of RAID in which Array Management Software maintains two or more identical copies
of data on separate disks.
MTBF
An abbreviation for Mean Time Between Failure, the average time from start of use to failure in
a large population of identical components or devices.

Manual
RAID
A Redundant Array of Independent Disks (RAID or RAID array) is 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’s member disks or the access path to it fails.
RAID levels
The original RAID level 1 through 5 was outlined in a research paper entitled A Case for Redundant Arrays of Inexpensive Disks. This paper was published in 1988 by David A. Patterson,
Garth Gibson, and Randy H. Katz of the University of California at Berkley. Counting the term
RAID 0 that refers to disk striping and later defined RAID 6, there are 7 levels of RAID.
SCSI
Small Computer System Interface.
SCSI ID
Also called SCSI ID#, is an octal representation of the unique address assigned to a SCSI device.
Spare, Spare Disk
A disk reserved for substitution of a like entity in case of the failure of that entity.
Swap
The replacement of a defective unit with a new unit. Units are parts of a disk subsystem that may
either be field replaceable by a vendor service representative or consumer replaceable.
