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.

Five types of array architectures, RAID 1 through RAID 5, 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 arrays.

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.

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.

User Manual

Definition of RAID Levels

RAID 0 is typically defined as a group of striped disk drives without parity or data 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 if one drive in a RAID 0 array fails, the entire array fails.

RAID 1, also known as disk mirroring, is simply a pair of disk drives that store 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.

12

User Manual


RAID 3 sector-stripes data across groups of drives, but one drive in the group is dedicated for storing 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 RAID 5 parity information is distributed across all the drives. Since there is 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.

Dual-level RAID achieves a balance between the increased data availability inherent in

RAID 1, RAID 3, RAID 5, or RAID 6 and the increased read performance inherent in disk striping (RAID 0). These arrays are sometimes referred to as RAID 0+1 (1E), RAID 30,

RAID 50 or RAID 60.

User Manual

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 is High data availability – any two drives can fail without loss of critical data.

In summary:

RAID 0 is the fastest and most efficient array type but offers no fault-tolerance. RAID

0 requires a minimum of one drive.

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 singleuser 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. It is a perfect solution for mission critical applications.

Block striping is provide, which yields higher performance than with individual drives. There is no redundancy.

Drives are paired and mirrored. All data is 100% duplicated on an equivalent drive. Fully redundant.

Data is striped across several physical drives.

Parity protection is used for data redundancy.





Requires N+2 drives to implement because of two-dimensional parity scheme.

Combination of RAID levels 0 and 1. This level provides striping and redundancy through mirroring. RAID 0+1 requires the use of an even number of disk drives to achieve data protection, while RAID 1E (Enhanced Mirroring) uses an odd number of drives.

Combination of RAID levels 0 and 3. This level is best implemented on two RAID 3 disk arrays with data striped across both disk arrays.

RAID 50 provides the features of both RAID 0 and RAID 5. RAID 50 includes both parity and disk striping across multiple drives. RAID 50 is best implemented on two RAID 5 disk arrays with data striped across both disk arrays.

RAID 60 combines both RAID 6 and RAID 0 features. Data is striped across disks as in RAID

0, and it uses double distributed parity as in

RAID 6. RAID 60 provides data reliability, good overall performance and supports larger volume sizes.

RAID 60 also provides very high reliability because data is still available even if multiple disk drives fail (two in each disk array).

1.3 Fibre Functions

1.3.1 Overview

Fibre Channel is a set of standards under the auspices of ANSI (American National

Standards Institute). Fibre Channel combines the best features from SCSI bus and

IP protocols into a single standard interface, including high-performance data transfer (up to 800 MB per second), low error rates, multiple connection topologies, scalability, and more. It retains the SCSI command-set functionality, but uses a Fibre

Channel controller instead of a SCSI controller to provide the interface for data transmission. In today’s fast-moving computer environments, Fibre Channel is the serial data transfer protocol choice for high-speed transportation of large volume of information between workstation, server, mass storage subsystems, and peripherals. Physically, the Fibre Channel can be an interconnection of multiple communication points, called N_Ports. The port itself only manages the connection between itself and another such end-port which, which could either be part of a switched network, referred to as a Fabric in FC terminology, or a point-to- point link. The fundamental elements of a Fibre Channel Network are Port and Node.

So a Node can be a computer system, storage device, or Hub/Switch.

This chapter describes the Fibre-specific functions available in the Fibre Channel

RAID controller. Optional functions have been implemented for Fibre Channel operation w h ich is only available in the Web browser-based RAID manager. The

LCD and VT-100 can’t be used to configure some of the options available for

Fibre Channel RAID controller.

1.3.2 Three ways to connect (FC Topologies)

A topology defines the interconnection scheme. It defines the number of devices that can be connected. Fibre Channel supports three different logical or physical arrangements (topologies) for connecting the devices into a network:

Point-to-Point

Arbitrated Loop(AL)

Switched (Fabric)

The physical connection between devices varies from one topology to another. In all of these topologies, a transmitter node in one device sends information to a receiver node in another device. Fibre Channel networks can use any combination of point-to-point, arbitrated loop (FC_AL), and switched fabric topologies to provide a variety of device sharing options.

Point-to-point

A point-to-point topology consists of two and only two devices connected by N- ports of which are connected directly. In this topology, the transmit Fibre of one device connects to the receiver Fibre of the other device and vice versa. The connection is not shared with any other devices. Simplicity and use of the full data transfer rate make this Point-to-point topology an ideal extension to the standard SCSI bus interface. The point-to-point topology extends SCSI connectivity from a server to a peripheral device over longer distances.

16

User Manual


Arbitrated Loop

The arbitrated loop (FC-AL) topology provides a relatively simple method of connecting and sharing resources. This topology allows up to 126 devices or nodes in a single, continuous loop or ring. The loop is constructed by daisy-chaining the transmit and receive cables from one device to the next or by using a hub or switch to create a virtual loop. The loop can be self-contained or incorporated as an element in a larger network. Increasing the number of devices on the loop can reduce the overall performance of the loop because the amount of time each device can use the loop is reduced. The ports in an arbitrated loop are referred as L-Ports.

Switched Fabric

A switched fabric a term is used in a Fibre channel to describe the generic switching or routing structure that delivers a frame to a destination based on the destination address in the frame header. It can be used to connect up to 16 million nodes, each of which is identified by a unique, world-wide name (WWN). In a switched fabric, each data frame is transferred over a virtual point-to-point connection. There can be any number of full-bandwidth transfers occurring through the switch. Devices do not have to arbitrate for control of the network; each device can use the full available bandwidth.

A fabric topology contains one or more switches connecting the ports in the FC network. The benefit of this topology is that many devices (approximately 2-24) can be connected. A port on a Fabric switch is called an F-Port (Fabric Port). Fabric switches can function as an alias server, multi-cast server, broadcast server, quality of service facilitator and directory server as well.

1.3.3 Basic Elements

The following elements are the connectivity of storages and Server components using the Fibre channel technology.

Cables and connectors

There are different types of cables of varies lengths for use in a Fibre Channel configuration. Two types of cables are supported: Copper and Optical (fiber).

Copper cables are used for short distances and transfer data up to 30 meters per link.

Fiber cables come in two distinct types: Multi-Mode fiber (MMF) for short distances (up to 2km), and Single-Mode Fiber (SMF) for longer distances (up to

10 kilometers). B y d e f a u l t , t h e R A I D s u b s y s t e m supports two short-wave multi-mode fibre optic SFP connectors.

Fibre Channel Adapter

Fibre Channel Adapter is a device that is connected to a workstation, server, or host system and control the protocol for communications.

Hubs

Fibre Channel hubs are used to connect up to 126 nodes into a logical loop. All connected nodes share the bandwidth of this one logical loop. Each port on a hub

User Manual

17

Fibre to SAS/SATA II RAID Subsystem contains a Port Bypass Circuit(PBC) to automatically open and close the loop to support hot pluggability.

Switched Fabric

Switched fabric is the highest performing device available for interconnecting large number of devices, increasing bandwidth, reducing congestion and providing aggregate throughput.

Each device is connected to a port on the switch, enabling an on-demand connection to every connected device. Each node on a Switched fabric uses an aggregate throughput data path to send or receive data.

1.3.4 LUN Masking

LUN masking is a RAID system-centric enforced method of masking multiple LUNs behind a single port. By using World Wide Port Names (WWPNs) of server HBAs,

LUN masking is configured at the volume level. LUN masking also allows s h a r i n g disk storage resource across multiple independent servers. A single large RAID device can be sub-divided to serve a number of different hosts that are attached to the RAID through the SAN fabric with LUN masking. So that only one or a limited number of servers can see that LUN, each LUN inside the RAID device can be limited.

LUN masking can be done either at the RAID device (behind the RAID port) or at the server HBA. It is more secure to mask LUNs at the RAID device, but not all RAID devices have LUN masking capability. Therefore, in order to mask LUNs, some HBA vendors allow persistent binding at the driver-level.

1.4 Array Definition

1.4.1 Raid Set

A Raid Set is a group of disk drives containing one or more logical volumes called

Volume Sets. It is not possible to have multiple Raid Sets on the same disk drives.

A Volume Set must be created either on an existing Raid Set or on a group of available individual disk drives (disk drives that are not yet a part of a Raid Set). If there are existing Raid Sets with available raw capacity, new Volume Set can be created. New

Volume Set can also be created on an existing Raid Set without free raw capacity by expanding the Raid Set using available disk drive(s) which is/are not yet Raid Set member. If disk drives 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.

18

User Manual


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 raw 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 while Volume 0 might be assigned a RAID 0+1 level.

1.5 High Availability

1.5.1 Creating Hot Spares

A hot spare drive is an unused online available drive, which is ready to replace a failed disk drive. In a RAID level 1, 0+1, 3, 5, 6, 30, 50, or 60 Raid Set, any unused online available drive installed but not belonging to a Raid Set can be defined as a hot spare drive. Hot spares permit you to replace failed drives without powering down the system.

When the RAID subsystem detects a drive failure, the system will do automatic and transparent rebuild using the 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 replaces.

User Manual

19


1.5.2 Hot-Swap Disk Drive Support

The RAID subsystem has built-in protection circuit to support the replacement of

SATA II hard disk drives without having to shut down or reboot the system. The removable hard drive tray can deliver “hot swappable” fault-tolerant RAID solution at a price much less than the cost of conventional SCSI hard disk RAID subsystems. This feature is provided in the RAID subsystem for advance fault tolerant RAID protection and

“online” drive replacement.

1.5.3 Hot-Swap Disk Rebuild

The Hot-Swap feature can be used to rebuild Raid Sets with data redundancy such as

RAID level 1, 0+1, 3, 5, 6, 30, 50 and 60. 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 continue the rebuild process if the subsystem is shut down or powered off abnormally during a reconstruction process.

5.3 Volume Set Function

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 raw 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.

5.3.1 Create Volume Set

The following are the Volume Set features:

1. Volume sets of different RAID levels may coexist on the same Raid Set.

2. Up to 128 Volume Sets in a Raid Set can be created in the RAID subsystem.

To create Volume Set from a Raid Set, expand the Volume Set Functions in the main menu and click on the Create Volume Set link. The Select The Raid Set To Create

On It screen will show all existing Raid Sets. Tick on the Raid Set where you want to create the Volume Set and then click on the Submit button.

The Volume Set setup screen allows user to configure the Volume Name, Capacity,

RAID level, Initialization Mode, Stripe Size, Cache Mode, Tagged Command Queuing, Fibre

Channel/LUN Base/LUN, and Volume To Be Created.

User Manual

Volume Name:

The default Volume Set name will appear as “Volume---VOL#XXX”. You can rename the Volume Set name provided it does not exceed the 16 characters limit.

Volume Raid Level:

Set the RAID level for the Volume Set. Click the down-arrow in the drop-down list. The available RAID levels for the current Volume Set are displayed. Select the preferred

RAID level.

Select Volume Capacity:

The maximum Volume Set size is displayed by default. If necessary, change the

Volume Set size appropriate for your application.

Greater Two TB Volume Support:

If the Volume Set size is over 2TB, an option “Greater Two TB Volume Support” will be automatically provided in the screen as shown in the example above. There are three options to select: “No”, “64bit LBA”, and “4K Block”).

No: Volume Set size is set to maximum 2TB limitation.

64bit LBA: Use this option for UNIX, Linux Kernel 2.6 or later, Windows Server 2003

+ SP1 or later versions, Windows x64, and other supported operating systems. The maximum Volume Set size is up to 512TB.

4K Block: Use this option for Windows OS such as Windows 2000, 2003, or XP.

The maximum Volume Set size is 16TB. Just use the Volume as “Basic Disk”.

Volume can’t be used as “Dynamic Disk”; also can’t be used in 512Bytes block service program.

Initialization Mode:

Set the Initialization Mode for the Volume Set. Initialization in Foreground mode is completed faster but must be completed before Volume Set becomes accessible.

Background mode makes the Volume Set instantly available but the initialization process

58

User Manual

Fibre to SAS/SATA II RAID Subsystem takes longer. No Init (To Rescue Volume) is used to create a Volume Set without initialization; normally used to recreate Volume Set configuration to recover data.

Stripe Size:

This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 0+1, 5 or 6 Volume Set. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or

128 KB.

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: Stripe Size in RAID level 3 can’t be modified.

Cache Mode:

The RAID subsystem supports two types of write caching: Write-Through and Write-Back.

Write-Through: data are both written to the cache and the disk(s) before the write

I/O is acknowledged as complete.

Write-Back: when data is written to cache, the I/O is acknowledged as complete, and some time later, the cached data is written or flushed to the disk(s). This provides better performance but requires a battery module support for the cache memory, or a UPS for the subsystem.

Tagged Command Queuing:

When this option is enabled, it enhances the overall system performance under multitasking operating systems by reordering tasks or requests in the command queue of the RAID system. This function should normally remain enabled.

Fibre Channel/LUN Base/LUN:

Fibre Channel: Each RAID controller has two 8Gbps Fibre Host Channels (ports).

Select the Fibre port where to map the LUN (Volume Set). Options are: 0, 1 and

0&1 Cluster. “0&1 Cluster” will make the LUN visible on both Fibre ports.

LUN Base: T h e b ase LUN number. Each LUN Base supports 8 LUNs.

LUN: Each Volume Set must be assigned a unique LUN ID number. A Fibre Port can connect up to 128 devices (LUN ID: 0 to 127). Select the LUN ID for the

Volume Set.

Volumes To Be Created:

Use this option to create several Volume Sets with the same Volume Set attributes. Up to 128 Volume Sets can be created.

5.5 System Controls

5.5.1 System Configuration

To set the RAID subsystem system configuration options, click the System

Configuration link under the System Controls menu. The System

Configurations screen will be shown. Set the desired system option as needed.

System Beeper Setting:

This option is used to Disable or Enable the system’s RAID controller alarm beeper.

Background Task Priority:

The Background Task Priority indicates how much time and system resource the RAID controller devotes to a background task, such as a rebuild operation. The RAID subsystem allows user to choose the background task priority (High 80%, Medium 50%,

Low 25%, and Ultra Low 5%) to balance between background task process and

Volume Set access. For high RAID subsystem performance, specify a low value.

JBOD/RAID Configuration:

The RAID subsystem supports JBOD and RAID configuration.

User Manual


SATA NCQ Support:

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.

Disabled or Enable the SATA NCQ function.

HDD Read Ahead Cache:

This option allows the users to disable the cache of the HDDs on the RAID subsystem. In some HDD models, disabling the cache in the HDD is necessary to prove the RAID subsystem functions correctly.

Volume Data Read Ahead:

This option allows the users to set the Volume Data Read Ahead function. Options are: Normal, Aggressive, Conservative, and Disabled.

HDD Queue Depth:

The queue depth is the number of I/O operations that can be run in parallel on a disk drive. HDD Queue Depth options are 1, 2, 4, 8, 16, and 32.

Disk Write Cache Mode:

The RAID subsystem supports Disk Write Cache Mode options: Auto, Enabled, and Disabled.

If the RAID subsystem has BBM (battery backup module), selecting the Auto option will automatically enable Disk Write Cache. On the other hand, if there is no BBM, the Auto option will disable Disk Write Cache.

Disk Capacity Truncation Mode:

The RAID subsystem use drive truncation so that drives from different 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 the subsystem. Options are:

Multiples Of 10G: If you have several 120GB drives from different vendors, chances are that the capacity varies slightly. For example, one drive might be

121.1 GB, and the other 120.4 GB. This drive truncation mode makes the

121.1 GB and 120.4 GB drives same capacity as 120 GB so that one could replace the other.

Multiples Of 1G: If you have 120 GB drives from different vendors, chances are that the capacity varies slightly. For example, one drive might be 121.1

GB, and the other 121.4 GB. This drive truncation mode makes the 121.1 GB and 121.4 GB drives same capacity 121 GB so that one could replace the other.

No Truncation: The capacity of the disk drive is not truncated.

5.5.2 HDD Power Management

MAID (Massive Array of Idle Disks) is a storage technology that employs a large group of disk drives in which only those drives in active use are spinning at any given time.

This reduces power consumption and prolongs the lives of the drives.

MAID is designed for Write Once, Read Occasionally (WORO) applications such as Data

Backup, Document, Mail server, and so on.

MAID technology focuses on "Green Storage Concept" to save power consumption and enhance disk drives effective usage, i.e., "disk drives are spun down when there is no activity or I/O on the drives".

In the RAID subsystem, MAID is implemented in the HDD Power Management menu.

Using the Advanced Power Management (APM) function of disk drives, HDD Power

Management has three options (MAID Levels): (Level 1) Place idle drives in Lower Power

Mode, where the drives’ heads are unloaded; (Level 2) Place idle drives in Low RPM

Mode, where drives’ heads are unloaded and slows down to around 4000 RPM; and

(Level 3) Spin down idle drives, where drives stops spinning and goes into sleep mode.

Stagger Power On Control:

This option allows the RAID subsystem’s power supply to power up in succession each HDD in the RAID subsystem. In the past, all the HDDs on the RAID subsystem are powered up altogether at the same time. This function allows the power transfer time (lag time) from the last HDD to the next one be set within the range of

0.4 to 6.0 seconds. Default is 0.7 seconds.

Time to HDD Low Power Idle: (MAID Level 1)

This option enables the RAID subsystem to place idle HDDs of a Raid Set in Low

Power Mode, where drives’ heads are unloaded. The power saving is around 15% to

20%. Recovery time is under a second.

Options are: Disabled, 2, 3, 4, 5, 6, and 7 (Minutes).

76

User Manual


Time to HDD Low RPM Mode: (MAID Level 2)

This option enables the RAID subsystem to place idle HDDs of a Raid Set in Low RPM

Mode, where drives’ heads are unloaded and drive platters speed is reduced to around 4000 RPM. The power saving is from 35% to 45%. Recovery time is 15 seconds.

Options are: Disabled, 10, 20, 30, 40, 50, and 60 (Minutes).

Time to Spin Down Idle HDD: (MAID Level 3)

This option enables the Raid subsystem to spin down HDDs of a Raid Set after they become idle after a preset period of time. In this level, the drives stop spinning and go into sleep mode. The power saving is from 60% to 70%. Recovery time is 30 to 45 seconds.

Options are: Disabled, 1 (For Test), 3, 5, 10, 15, 20, 30, 40, and 60 (Minutes).

NOTE: To verify if the disk drive you use supports MAID or APM, select “RaidSet Hierarchy” and click the disk drive (E# Slot#) link.

Check in the Device Information screen if the Disk APM Support shows “Yes”.

5.5.3 Fibre Channel Config

To set the Fibre Channel Configuration function, move the mouse cursor to the main menu and click on the Fibre Channel Config. The Fibre Channel Configuration screen will be shown. Configure the desired function.

WWNN (World Wide Node Name)

The WWNN of the FC RAID system is shown at top of the configuration screen. This is an eight-byte unique address factory assigned to the FC RAID, common to both FC ports.

WWPN (World Wide Port Name)

Each FC port has its unique WWPN, which is also factory assigned. Usually, the

WWNN:WWPN tuple is used to uniquely identify a port in the Fabric.

Channel Speed

Each FC port speed can be configured either as 2 Gbps, 4 Gbps, or 8 Gbps channel.

Another option is to use “Auto” for auto speed negotiation between 2Gbps/4Gbps/8Gbps.

The RAID system’s default setting is “Auto”, which should be adequate under most conditions. The Channel Speed setting takes effect during the next connection. That means a link down / link up should be applied for the change to take effect. The current connection speed is shown at end of the row. You have to click the “Fibre Channel

Config” link again from the menu frame to refresh the current speed information.

78

User Manual


Channel Topology

Each Fibre Channel can be configured to the following Topology options: Fabric,

Point-to-Point, Loop or Auto. The default Topology is set to “Auto”, which takes precedence of Loop Topology. Restarting the RAID controller is needed for any topology change to take effect. The current connection topology is shown at end of the row. You have to click the “Fibre Channel Config” link again from the menu frame to refresh the current topology information. Note that current topology is shown as “None” when no successful connection is made for the channel.

Hard Loop ID

This setting is effective only under Loop topology. When enabled, you can manually set the Loop ID in the range from 0 to 125. Make sure this hard assigned ID does not conflict with other devices on the same loop, otherwise the channel will be disabled. It is a good practice to disable the hard loop ID and let the loop itself auto-arrange the Loop ID.

NOTE: For reliable operation of the RAID subsystem and depending on how the subsystem is connected, it is recommended to setup

Channel Speed and Channel Topology as follows:

RAID subsystem is connected to:

Channel Speed setting:

Channel Topology setting:

8Gb FC switch 8Gb Fabric

4Gb FC switch 4Gb Fabric

2Gb FC switch

8Gb FC HBA

(no switch)

4Gb FC HBA

(no switch)

2Gb FC HBA

(no switch)

2Gb Fabric

8Gb Loop

4Gb Loop

2Gb Loop

“Fabric” topology is used when there is switch.

“Loop” topology is used when there is no switch.

The Speed setting follows the FC switch speed if there is switch. If there is no FC switch, the Speed setting follows the FC HBA speed.

6.2 Upgrading the RAID Controller’s Firmware

Upgrading Firmware Using Flash Programming Utility

Since the RAID subsystem’s controller features flash firmware, it is not necessary to change the hardware flash chip in order to upgrade the controller firmware. User can simply re-program the old firmware through the RS-232 port. New releases of the firmware are available in the form of binary file at vendor’s FTP. The file available at the

FTP site is usually a self-extracting file that contains the following:

XXXXVVV.BIN Firmware Binary (where “XXXX” refers to the model name and

“VVV” refers to the firmware version)

README.TXT It contains the history information of the firmware change. Read this file first before upgrading the firmware.

These files must be extracted from the compressed file and copied to one directory in the host computer.

Establishing the Connection for the RS-232

The firmware can be downloaded to the RAID subsystem’s controller using an ANSI/VT-

100 compatible terminal emulation program or web browser-based RAID Manager remote management page.

With terminal emulation program, you must complete the appropriate installation and configuration procedure before proceeding with the firmware upgrade. Whichever terminal emulation program is used must support the ZMODEM file transfer protocol.

Web browser-based RAID Manager can be used to update the firmware. A web browser must have been setup before proceeding with the firmware upgrade.
