Introduction
The SurfRAID16S3 RAID subsystem is a SAS-to-Serial ATA II RAID (Redundant
Arrays of Independent Disks) disk array subsystem. It consists of a RAID disk
array controller and sixteen (16) disk trays.
The subsystem is a “Host Independent” RAID subsystem supporting RAID levels
0, 1, 3, 5, 6, 0+1 and JBOD. Regardless of the RAID level the subsystem is
configured for, each RAID array consists of a set of disks which to the user
appears to be a single large disk capacity.
One unique feature of these RAID levels is that data is spread across separate
disks as a result of the redundant manner in which data is stored in a RAID
array. If a disk in the RAID array fails, the subsystem continues to function
without any risk of data loss. This is because redundant information is stored
separately from the data. This redundant information will then be used to reconstruct any data that was stored on a failed disk. In other words, the subsystem can tolerate the failure of a drive without losing data while operating
independently of each other.
The subsystem is also equipped with an environment controller which is
capable of accurately monitoring the internal environment of the subsystem such
as; power supplies, fans, temperatures and voltages. The disk trays allow
you to install any type of 3.5-inch hard drive. Its modular design allows hotswapping of hard drives, fans and power supplies without interrupting the
subsystem’s operation.

1.2 RAID Concepts
RAID Fundamentals
The basic idea of RAID (Redundant Array of Independent Disks) is to combine
multiple inexpensive disk drives into an array of disk drives to obtain performance,
capacity and reliability that exceeds that of a single large drive. The array of
drives appears to the host computer as a single logical drive.
Six types of array architectures, RAID 1 through RAID 6, were originally defined;
each provides disk fault-tolerance with different compromises in features and
performance. In addition to these five redundant array architectures, it has become
popular to refer to a non-redundant array of disk drives as a RAID 0 array.
Disk Striping
Fundamental to RAID technology is striping. This is a method of combining
multiple drives into one logical storage unit. Striping partitions the storage
space of each drive into stripes, which can be as small as one sector (512
bytes) or as large as several megabytes. These stripes are then interleaved in
a rotating sequence, so that the combined space is composed alternately of
stripes from each drive. The specific type of operating environment determines
whether large or small stripes should be used.
Most operating systems today support concurrent disk I/O operations across
multiple drives. However, in order to maximize throughput for the disk subsystem,
the I/O load must be balanced across all the drives so that each drive can be kept
busy as much as possible. In a multiple drive system without striping, the disk I/O
load is never perfectly balanced. Some drives will contain data files that are
frequently accessed and some drives will rarely be accessed.
Page 9
By striping the drives in the array with stripes large enough so that each record
falls entirely within one stripe, most records can be evenly distributed across all
drives. This keeps all drives in the array busy during heavy load situations. This
situation allows all drives to work concurrently on different I/O operations, and
thus maximize the number of simultaneous I/O operations that can be performed
by the array.
Definition of RAID Levels
RAID 0
redundancy. RAID 0 arrays can be configured with large stripes for multi-user
environments or small stripes for single-user systems that access long sequential
records. RAID 0 arrays deliver the best data storage efficiency and performance
of any array type. The disadvantage is that is if one drive in a RAID 0 array fails,
the entire array fails.
is typically defined as a group of striped disk drives without parity or data
Page 10
RAID 1
duplicate data, but appear to the computer as a single drive. Although striping is
not used within a single mirrored drive pair, multiple RAID 1 arrays can be striped
together to create a single large array consisting of pairs of mirrored drives. All
writes must go to both drives of a mirrored pair so that the information on the
drives is kept identical. However, each individual drive can perform simultaneous,
independent read operations. Mirroring thus doubles the read performance of a
single non-mirrored drive and while the write performance is unchanged. RAID 1
delivers the best performance of any redundant array type. In addition, there is
less performance degradation during drive failure than in RAID 5 arrays.
, also known as disk mirroring, is simply a pair of disk drives that store
Page 11
RAID 3
sector-stripes data across groups of drives, but one drive in the group is
dedicated to storing the parity information. RAID 3 relies on the embedded ECC
in each sector for error detection. In the case of drive failure, data recovery is
accomplished by calculating the exclusive OR (XOR) of the information recorded
on the remaining drives. Records typically span all drives, which optimizes the
disk transfer rate. Because each I/O request accesses every drive in the array,
RAID 3 arrays can satisfy only one I/O request at a time. RAID 3 delivers the best
performance for single-user, single-tasking environments with long records.
Synchronized-spindle drives are required for RAID 3 arrays in order to avoid
performance degradation with short records. RAID 5 arrays with small stripes can
yield similar performance to RAID 3 arrays.
Under
no dedicated parity drive, all drives contain data and read operations can be
overlapped on every drive in the array. Write operations will typically access one
data drive and one parity drive. However, because different records store their
parity on different drives, write operations can usually be overlapped.
RAID 5
parity information is distributed across all the drives. Since there is
Page 12
RAID 6
is similar to RAID 5 in that data protection is achieved by writing parity
information to the physical drives in the array. With RAID 6, however, two sets of
parity data are used. These two sets are different, and each set occupies a capacity
equivalent to that of one of the constituent drives. The main advantage of RAID 6
High data availability – any two drives can fail without loss of critical data.
is
Page 13
Dual-level RAID
achieves a balance between the increased data availability
inherent in RAID 1 and RAID 5 and the increased read performance inherent in
disk striping (RAID 0). These arrays are sometimes referred to as
RAID 10 and RAID 0+5 or RAID 50.
In summary:
RAID 0+1
• RAID 0 is the fastest and most efficient array type but offers no faulttolerance. RAID 0 requires a minimum of two drives.
• RAID 1 is the best choice for performance-critical, fault-tolerant
environments. RAID 1 is the only choice for fault-tolerance if no more than
two drives are used.
• RAID 3 can be used to speed up data transfer and provide fault-tolerance in
single-user environments that access long sequential records. However,
RAID 3 does not allow overlapping of multiple I/O operations and requires
synchronized-spindle drives to avoid performance degradation with short
records. RAID 5 with a small stripe size offers similar performance.
• RAID 5 combines efficient, fault-tolerant data storage with good performance
characteristics. However, write performance and performance during
drive failure is slower than with RAID 1. Rebuild operations also require
more time than with RAID 1 because parity information is also
reconstructed. At least three drives are required for RAID 5 arrays.
• RAID 6 is essentially an extension of RAID level 5 which allows for
additional fault tolerance by using a second independent distributed
parity scheme (two-dimensional parity). Data is striped on a block level
across a set of drives, just like in RAID 5, and a second set of parity
is calculated and written across all the drives; RAID 6 provides for an
extremely high data fault tolerance and can sustain multiple
simultaneous drive failures. The perfect solution for mission critical
applications.

1.3 Serial-Attached SCSI (SAS) Overview
What is SAS? Serial-Attached SCSI (SAS) is the newest storage interface for
Direct-Attached Storage (DAS). SAS is the successor to the highly successful
parallel Ultra 320 SCSI interface. SAS improves and expands upon the parallel
SCSI technology, and is supported by the ANSI T10 Standards Committee.
Why SAS? Answer; Performance, connectivity and scalability.
One of the major differences between parallel SCSI and SAS is that SAS uses a
serial bus as opposed to a parallel bus. Ultra 320 parallel SCSI has reached the
limit of parallel SCSI performance, and anything beyond Ultra 320 is not
feasible due to the fact that parallel SCSI clock rates are limited
by bit- skewing. This is where SAS comes in. SAS transmission is done
serially, and results in a myriad of advantages over parallel SCSI.
Performance
• The serial nature of SAS results in a huge increase in performance over
parallel SCSI.
• No bit-skewing and is self-clocking.
• Transfer rates up to 3.0 Gb/s per link.
• Full duplex which results in a total of 6.0 Gb/s per link.
• Link aggregation into 4x wide ports for a total of 24.0 Gb/s.
•
Extensive command queue.
Connectivity/Scalability
A new concept introduced by SAS is the expander. Expanders act like
miniature switches for routing data from the SAS controller chip to the hard
disks. The connectivity / scalability benefits of SAS are:
• Dedicated point-to-point connection between initiator and target.
• SAS expanders make scalability up to 16K devices in a single SAS
domain possible.
• Each device is uniquely identified with a World Wide Name (WWN), so
there is no longer a need for SCSI IDs.
•
Using SCSI Tunneling Protocols (STP), SAS is compatible with SATA II
HDDs.
Page 16
Availability
In this fast-paced society, data needs to be available to clients whenever they
need it. SAS was designed with availability in mind. SAS include the following
benefits:
• Dual ports for redundant controller functionality
• Support for multiple initiators
• Hot swappable for easy removal / replacement of the SAS drive
1.4 Array Definition
1.4.1 RAID Set
A RAID Set is a group of disks containing one or more volume sets. It has the
following features in the RAID subsystem controller:
1. Up to 128 RAID Sets are supported per RAID subsystem controller.
2. It is impossible to have multiple RAID Sets on the same disks.
A Volume Set must be created either on an existing RAID set or on a group of
available individual disks (disks that are not yet a part of a raid set). If there
are pre-existing raid sets with available capacity and enough disks for
specified RAID level desired, then the volume set will be created in the
existing raid set of the user’s choice. If physical disks of different capacity
are grouped together in a raid set, then the capacity of the smallest disk will
become the effective capacity of all the disks in the raid set.
Page 17
1.4.2 Volume Set
A Volume Set is seen by the host system as a single logical device. It is
organized in a RAID level with one or more physical disks. RAID level refers
to the level of data performance and protection of a Volume Set. A Volume
Set capacity can consume all or a portion of the disk capacity available in a
RAID Set. Multiple Volume Sets can exist on a group of disks in a RAID Set.
Additional Volume Sets created in a specified RAID Set will reside on all the
physical disks in the RAID Set. Thus each Volume Set on the RAID Set will
have its data spread evenly across all the disks in the RAID Set. Volume Sets
of different RAID levels may coexist on the same RAID Set.
In the illustration below, Volume 1 can be assigned a RAID 5 level of operation
while Volume 0 might be assigned a RAID 0+1 level of operation.
1.4.3 Easy of Use features
1.4.3.1 Instant Availability/Background Initialization
RAID 0 and RAID 1 volume set can be used immediately after the creation. But
the RAID 3, 5 and 6 volume sets must be initialized to generate the parity. In
the Normal Initialization, the initialization proceeds as a background task, the
volume set is fully accessible for system reads and writes. The operating system can instantly access to the newly created arrays without requiring a reboot
and waiting the initialization complete. Furthermore, the RAID volume set is
also protected against a single disk failure while initialing. In Fast Initialization,
the initialization proceeds must be completed before the volume set ready for
system accesses.
Page 18
1.4.3.2 Array Roaming
The RAID subsystem stores configuration information both in NVRAM and on
the disk drives It can protect the configuration settings in the case of a disk
drive or controller failure. Array roaming allows the administrators the ability to
move a completely raid set to another system without losing the RAID
configuration and data on that raid set. If a server fails to work, the raid set
disk drives can be moved to another server and inserted in any order.
1.4.3.3 Online Capacity Expansion
Online Capacity Expansion makes it possible to add one or more physical
drive to a volume set, while the server is in operation, eliminating the need to
store and restore after reconfiguring the raid set. When disks are added to a
raid set, unused capacity is added to the end of the raid set. Data on the
existing volume sets residing on that raid set is redistributed evenly across all
the disks. A contiguous block of unused capacity is made available on the raid
set. The unused capacity can create additional volume set. The expansion
process is illustrated as following figure.
Page 19
The RAID subsystem controller redistributes the original volume set over the
original and newly added disks, using the same fault-tolerance configuration.
The unused capacity on the expand raid set can then be used to create an
additional volume sets, with a different fault tolerance setting if user need to
change.
1.4.3.4 Online RAID Level and Stripe Size Migration
User can change both the RAID level and stripe size of an existing volume set,
while the server is online and the volume set is in use. Online RAID level/stripe
size migration can prove helpful during performance tuning activities as well as
in the event that additional physical disks are added to the RAID subsystem.
For example, in a system using two drives in RAID level 1, you could add
capacity and retain fault tolerance by adding one drive. With the addition of
third disk, you have the option of adding this disk to your existing RAID logical
drive and migrating from RAID level 1 to 5. The result would be parity fault
tolerance and double the available capacity without taking the system off.
Page 20
1.4.4 High availability
1.4.4.1 Creating Hot Spares
A hot spare drive is an unused online available drive, which is ready for
re- placing the failure disk drive. In a RAID level 1, 0+1, 3, 5 or 6 raid set,
any unused online available drive installed but not belonging to a raid set
can define as a hot spare drive. Hot spares permit you to replace failed
drives without powering down the system. When RAID subsystem detects a
UDMA drive failure, the system will automatic and transparent rebuilds
using hot spare drives. The raid set will be reconfigured and rebuilt in the
background, while the RAID subsystem continues to handle system request.
During the automatic rebuild process, system activity will continue as normal,
however, the system performance and fault tolerance will be affected.
Important:
The hot spare must have at least the same or more capacity as the
drive it is replacing.
1.4.4.2 Hot-Swap Disk Drive Support
The RAID subsystem has built the protection circuit to support the replacement
of UDMA hard disk drives without having to shut down or reboot the system.
The removable hard drive tray can deliver “hot swappable,” fault-tolerant RAID
solutions at prices much less than the cost of conventional SCSI hard disk
RAID subsystems. We provide this feature for subsystems to provide the
advanced fault tolerant RAID protection and “online” drive replacement.
Page 21
1.4.4.3 Hot-Swap Disk Rebuild
A Hot-Swap function can be used to rebuild disk drives in arrays with data
redundancy such as RAID level 0, 1, 0+1, 3, 5 and 6. If a hot spare is not
available, the failed disk drive must be replaced with a new disk drive so that
the data on the failed drive can be rebuilt. If a hot spare is available, the
rebuild starts automatically when a drive fails. The RAID subsystem
automatically and transparently rebuilds failed drives in the background with user
definable rebuild rates. The RAID subsystem will automatically restart the
system and the rebuild if the system is shut down or powered off abnormally
during a reconstruction procedure condition. When a disk is Hot Swap,
although the system is functionally operational, the system may no longer be
fault tolerant. Fault tolerance will be lost until the removed drive is replaced
and the rebuild operation is completed.

Chapter 3
RAID Configuring
The subsystem has a setup configuration utility built in containing important
information about the configuration as well as settings for various optional
functions in the subsystem. This chapter explains how to use and make
changes to the setup utility.
Configuration Methods
There are three methods of configuring the subsystem. You may configure
through the following methods:
• VT100 terminal connected through the controller’s serial port
• Front panel touch-control keypad
• Web browser-based Remote RAID management
Important:
The subsystem allows you to access the utility using only one method at
!
a time
. You cannot use both methods at the same time.
3.1 Configuring through a Terminal
Configuring through a terminal will allow you to use the same configuration
options and functions that are available from the LCD panel. To start-up:
1. Connect a VT100 compatible terminal or a PC operating in an equivalent
Page 34
terminal emulation mode to the monitor port located at the rear of the
subsystem.
Note:
You may connect a terminal while the subsystem’s power is on.
2. Power-on the terminal.
3. Run the VT100 program or an equivalent terminal program.
Page 35
4. The default setting of the monitor port is 115200 baud rate, 8 data bit,
non-parity, 1 stop bit and no flow control.
Page 36
5. Click disconnect button.
6. Open the File menu, and then open Properties.
Page 37
7. Open the Settings Tab.
8. Open the Settings Tab. Function, arrow and ctrl keys act as: Terminal
Keys, Backspace key sends: Crtl+H, Emulation: VT100, Telnet terminal:
VT100, Back scroll buffer lines: 500. Click OK.
Page 38
9. Now, the VT100 is ready to use. After you have finished the VT100 Terminal
setup, you may press “ X “ key (in your Terminal) to link the RAID
subsystem and Terminal together. Press “X’ key to display the disk array
Monitor Utility screen on your VT100 Terminal.
10. The Main Menu will appear.

Main Menu
The main menu shows all function that enables the customer to execute
actions by clicking on the appropriate link.
Note:
The password option allows user to set or clear the raid subsystem’s
password protection feature. Once the password has been set, the user
can only monitor and configure the raid subsystem by providing the
correct password. The password is used to protect the internal RAID
sub- system from unauthorized entry. The controller will check the
password only when entering the Main menu from the initial screen.
The RAID subsystem will automatically go back to the initial screen
when it does not receive any command in twenty seconds. The RAID
subsystem password is default setting at 00000000 by the manufacture.

web browser-based application, which utilizes the browser installed on your
operating system. Web browser-based remote RAID management can be used to
man- age all the raid function.
To configure internal RAID subsystem on a remote machine, you need to know its
IP Address. Launch your web browser by entering http://[IP Address] in the remote
web browser.
Important:
The default static IP is “192.168.001.100”. DHCP function is enabled
by default when RAID system is shipped. You can configure correct IP
Address through the LCD panel, serial terminal or through the GUI via the

Configuration Procedures
Below are a few practical examples of concrete configuration procedures.
3.5 Quick Create
The number of physical drives in the raid subsystem determines the RAID
levels that can be implemented with the raid set. You can create a raid set
associated with exactly one volume set. The user can change the raid level,
capacity, Volume Initialization Mode and stripe size. A hot spare option is also
created depending upon the existing configuration.
If volume size over 2TB, it will be provided one option “Create 2TB Volume
Support” shown in the above menu. There are three settings for this option
“No”, “64bit LBA”, “4K Block”.

1. Once the Expand Raid Set process has started, user cannot
stop it. The process must be completed.
2. If a disk drive fails during raid set expansion and a hot spare is
available, an auto rebuild operation will occur after the raid set
expansion completes.
Page 54
A migrating occurs when a disk is added to a raid set. Migration status is
displayed in the raid status area of the Raid Set information where the disk has
been added to a raid set. Migrating status is also displayed in the associated
volume status area of the volume set Information when a disk is added to a raid
set.
Page 55
3.6.4 Offline Raid Set
A user can move a Raid Set (group of disk drives) to another RAID system
with the power on. User can use the Offline Raid Set option to offline the
raid set. After user complete the offline function, the HDD State will change to
offline Mode.
To offline a raid set, click on the Offline Raid Set link. The “Select the RAID
SET to Offline” screen is displayed showing all raid set existing in the current

3.7 Volume Set Function
A volume set is seen by the host system as a single logical device. It is
organized in a RAID level with one or more physical disks. RAID level refers
to the level of data performance and protection of a volume set. A volume set
capacity can consume all or a portion of the disk capacity available in a
raid set. Multiple volume sets can exist on a group of disks in a raid set.
Additional volume sets created in a specified raid set will reside on all the
physical disks in the raid set. Thus each volume set on the raid set will have
its data spread evenly across all the disks in the raid set.
3.7.1 Create Volume Set
The following is the volume set features:
1.) Volume sets of different RAID levels may coexist on the same raid set.
2.) Up to 16 volume sets in a raid set can be created by the RAID subsystem
controller.

Strip Size:
This parameter sets the size of the stripe written to each disk in a RAID 0, 1,
0+1, 5 or 6 logical drive. You can set the stripe size to 4KB, 8KB, 16KB, 32KB,
64KB, or 128KB.
A larger stripe size produces better read performance, especially if your
computer does mostly sequential reads. However, if you are sure that your
computer does random reads more often, select a small stripe size
Note: RAID level 3 can’t modify strip size.
Cache Mode:
The RAID subsystem supports Write-Through Cache and Write-Back Cache.
Tag Queuing:
The Enabled option is useful for enhancing overall system performance under
multi-tasking operating systems. The Command Tag (Drive Channel) function
controls the SAS command tag queuing support for each drive channel. This
function should normally remain enabled. Disable this function only when using
older SAS drives that do not support command tag queuing
SAS Port/LUN Base/LUN:
SAS Port: Two 3Gbps SAS channel can be applied to the internal RAID
subsystem
. Choose the SAS Port# option 0, 1 and 0&1 cluster.
Page 63
LUN Base: Each SAS device attached to the SAS card, as well as the card
itself, must be assigned a unique SAS ID number. A SAS channel can connect
up to 128 (0 to 127) devices. The RAID subsystem is as a large SAS device
and should be assign an LUN base from a list of SAS LUNs.
LUN: Each SAS LUN base can support up to 8 LUNs. Most SAS Channel
host adapter treats each LUN like a SAS disk.

devotes to a rebuild operation. The RAID subsystem allows user to choose the
rebuild priority (Ultra Low, Low, Medium, High) to balance volume set access
and rebuild tasks appropriately. For high array performance, specify a Low
value.
Page 73
Terminal Port Configuration:
Speed setting values are 1200, 2400, 4800, 9600, 19200, 38400, 57600, and
115200.
Stop Bits values are 1 bit and 2 bits.
Note: Parity value is fixed at None.
Data Bits value is fixed at 8 bits.
JBOD/RAID Configuration
The RAID subsystem supports JBOD and RAID configuration.
Maximum SATA Mode Supported:
The 16 SATA drive channel can support up to SATA ll, which runs up to 300MB/s.
NCQ is a command protocol in Serial ATA that can only be implemented on native
Serial ATA hard drives. It allows multiple commands to be outstanding within a
drive at the same time. Drives that support NCQ have an internal queue where
outstanding commands can be dynamically rescheduled or re-ordered, along with
the necessary tracking mechanisms for outstanding and completed portions of
the workload. RAID subsystem allows user to choose the SATA Mode: SATA150,
SAT150+NCQ, SAT300, SATA300+NCQ.
HDD Read-Ahead Cache:
This option allows the users to disable the cache of the HDDs on the RAID
subsystem. To some HDD models, disabling the cache in the HDD is
necessary to prove the RAID subsystem functions correctly.
Stagger Power-On Control:
This option allows the power supplier to power up in order each HDD on the
RAID subsystem. In the past, all the HDDs on the RAID subsystem are
powered up altogether at the same time. The power transfer time (lag time)
from the last HDD to the next one can be set within the range of 0.4 to 6.0.
Page 74
Spin Down Idle HDD (Minutes):
This option is to spin down hard drives after they have been idle for a selectable amount of time. The setting values are Disabled, 1(For Testing), 3, 5, 10, 15,
20, 30, 40, 50, and 60.
Disk Write Cache Mode:
The RAID subsystem supports auto, enabled and disabled. When the RAID subsystem with BBM (battery backup module) the auto option will be Enabled disk
write cache. Otherwise, the auto option will be Disable disk write cache.
Disk Capacity Truncation Mode:
This RAID subsystem use drive truncation so that drives from differing vendors
are more likely to be able to be used as spares for each other. Drive truncation
slightly decreases the usable capacity of a drive that is used in redundant
units.
Multiples Of 10G: If you have 120 GB drives from different vendors; chances
are that the capacity varies slightly. For example, one drive might be 123.5 GB,
and the other 120 GB. This drive Truncation mode Multiples of 10G uses the
same capacity for both of these drives so that one could replace the other.
Multiples Of 1G: If you have 123 GB drives from different vendors; chances
are that the capacity varies slightly. For example, one drive might be 123.5 GB,
and the other 123.4 GB. This drive Truncation mode Multiples of 1G uses the
same capacity for both of these drives so that one could replace the other.
No Truncation: RAID system performs no truncation to the disk capacity.
MAC Over Two TB:
Use this option to enable volume size over 2TB in MAC O/S.

Array Maintenance
This chapter describes more information about your Disk Array. The
following items are described in detail.
• Updating Firmware
• Hot Swap Components
4.1 Upgrading the Firmware
Upgrading Flash Firmware Programming Utility
Since the RAID subsystem controller features flash firmware, it is not necessary to
change the hardware flash chip in order to upgrade the RAID firmware. The
user can simply re-program the old firmware through the RS-232 port or Web
GUI interfaces. New releases of the firmware are available in the form of a DOS
file and can be downloaded from the Partners Data Systems support webpage. The
file available at the support webpage .zip file that contains the following:
• XXXXVVV.bin Firmware Binary and the XXXXVVV-boot.bin (where
“XXXX” refers to the model name and “VVV” refers to the firmware version)
• README.TXT that contains the history information of the firmware
changes and important firmware notes. Read this file first before upgrading
the firmware.
These files must be extracted from the compressed file and copied to one
directory in drive A or C. The boot.bin file must be installed first before
the .bin file is installed. See the Readme.txt file for important notes
regarding the upgrade.
Establishing the Connection for the RS-232
The firmware can be downloaded to the RAID subsystem controller by using an
ANSI/VT-100 compatible terminal emulation program or Remote web browser
management. You must complete the appropriate installation procedure before
proceeding with this firmware upgrade. Whichever terminal emulation program
is used must support the ZMODEM file transfer protocol.
