1.0 Diamond Storage Array-VT Product Overview

The Diamond Storage Array-VT Class offers up to 30 Virtual Tape drives and up to 60 virtual tapes in a rack mount or floor model configuration.

The Diamond-VT appears and functions to ISV (Independent Software Vender) applications as if it were a traditional tape device although it is actually an array of ATA disk drives. Virtual tape provides increased performance for restore and backup operations, RAID protection of data, and compatibility with existing software and backup procedures. Virtual Tape can be used anywhere traditional tape is used to augment and enhance existing tape drive/library investments.

With the cost effective approach of using ATA disk drives, you can add more storage capacity as your needs grow without the costs of other disk storage technologies. You can also improve the performance and capacity of the Diamond-VT cabinet as technology progresses by simply replacing disk drive sleds and host interface cards.

The Diamond-VT is operating system independent and supports all popular computer hardware platforms and network environments.

Two interface options are available: a 2-gigabit Fibre Channel interface and an Ultra160 SCSI interface.

The Diamond-VT is a fully populated, turnkey solution with drives pre-installed. It is fully supported by a highly trained customer service and engineering staff.

The Diamond-VT uses Aggregated Data Transfer

Technology (ADXT

) to merge the performance of multiple ATA drives to achieve sustained, full bandwidth data transfer rates. ADXT provides end users with the power and sophisticated data control needed to take moderately priced ATA disk drives, combine them in a disk storage array, and power them to the performance levels of SCSI or Fibre Channel disk arrays.

2.0 Diamond-VT Technical Overview

The Diamond-VT uses Aggregated Data Transfer Technology (ADXT) to achieve the high data transfer performance you need. ADXT sustained, full bandwidth Fibre Channel data transfer rates.

merges the performance of multiple ATA drives together to achieve

Unlike other storage arrays which use expensive SCSI or Fibre Channel disk drives to achieve performance, the Diamond Series uses lower cost ATA disk drives combined with an intelligent midplane to create a storage array with exceptional price and performance characteristics.

The intelligent midplane contains hardware and software which provide the proprietary ADXT

switched data management and data movement

technology, to create a higher performance storage solution.

Using this technology, we are able to provide a storage array that delivers faster sustained data transfer rates as well as impressive I/Os per second at a new price point in the storage market.

The Diamond Array is made up of dual SCSI or Fibre Channel host interface cards, the intelligent

midplane, a system management card, and 12 independent disk drive sleds containing up to 24 ATA disk drives.

ADXT Powers ATA to New Levels

The original notion of RAID was to build high capacity, reliable storage subsystems using large numbers of inexpensive disk drives. Thus its original definition:

Inexpensive Drives

became

Redundant Array of Independent Drives

Redundant Array of

. Over time that definition

and the inherent cost advantage in a RAID system was lost. The Diamond Series provides a high capacity, high performance and highly reliable disk array that uses the merged power of many inexpensive ATA disk drives.

Intelligent Midplane

The heart of the Diamond Series storage array is the intelligent midplane with ADXT

to sum or

aggregate

the data rates of individual ATA disk drives to create high data transfer rates. This technology enables features such as serverless backup, advanced error protection, metadata storage techniques, virtualization software, thermal management and advanced enclosure services.

The midplane contains a combination of custom Application Specific Integrated Circuits (ASICs), processors and proprietary embedded software. It is divided into three main processing sections which handle the data being read or written to the ATA disk drives from the Fibre Channel or SCSI host interfaces. The Virtual Device Manager (VDM), Data Routing Fabric (DRF) and ATA

VIRTUAL DEVICE MANAGER

Interface Engines (AIE) organize data streams for storage or retrieval.

Virtual Drive Manager

Data is accessed through Virtual Drives using an implementation of the standard SCSI protocol controlled by the Virtual Device Manager. The VDM adds capabilities such as RAID, data management services, enclosure management services, serverless backup, data replication using SCSI Extended Copy and LUN mapping.

Data Routing Fabric

Incoming or outgoing data is routed between the ATA Interface Engines (AIE) and the Fibre Channel or SCSI interface by the custom Data Routing Fabric ASIC, a high speed, low latency transfer fabric with more than 2 GB/sec. of bandwidth supported by up to 512 Megabytes of memory.

ATA Interface Engine (AIE)

The interface to each pair of drives is through a custom ATA Interface Engine ASIC. The AIE implements the typically software-intensive ATA interface completely in silicon. Each AIE contains a dedicated ATA protocol processor to completely automate command and protocol processing. Automated command overlapping and queuing maximizes the performance of multi-threaded I/O. The AIE transfers data using double-clocking technology at 66 megabytes per second. The Diamond-VT contains 12 AIEs for a parallel transfer rate of 792

megabytes per second. In

3.2 Diamond-VT Physical Setup

The Diamond-VT is shipped completely assembled with two 120 VAC power cords for use in the United States and Canada.

Immediately upon receipt, check the shipping carton for damage from mishandling. Contact us at once by the means easiest for you (see

Warranty

on page A-xv) if the carton has been mishandled or displays any signs of damage.

Floor Model

The Diamond-VT is heavy (about 92 pounds fully loaded) and requires two people to lift and carry it safely. Place the Diamond-VT on a level surface and make sure there is adequate space in the front and back of the unit for proper cooling and airflow. Continue with the general instructions.

Rack Mount

The Diamond-VT fully loaded is heavy (about 86 pounds). The unit should be handled with care and requires two people to lift, carry and/or install it safely.

The Diamond Array can be mounted via several different methods in a 19” rack with 3U (5.25”) of vertical space required. Air flow should not be restricted in any way.

Installation in a rack may create a differential between the room ambient temperature and the internal ambient temperature in the rack. While the maximum internal operating temperature of the Diamond-VT is 47°C, you should not run the system at the maximum temperature for extended periods. Therefore, ensure that the room ambient temperature is kept below 30°C for best operation.

Each side of the rack mount Diamond-VT chassis has three pairs of mounting holes. One is located near the front of the rack, one near the unit’s center of gravity, and one near the rear of the rack. The holes accommodate 10/32 screws but the screws can protrude no farther than .375 inches into the rack.

Spaced rail pairs in some rackmount cabinets.

You can mount the Diamond-VT using two sets of rail pairs spaced to accommodate the overall length of the unit (approximately 23 inches). Mount using the rack mount brackets on the front and rear of the unit fastened to the rail pairs using 10/32 pan head screws with lock and flat washers.

Rack mount cabinets with stationary shelf or tray system.

The shelf or tray must be able to support at least 125 pounds. The shelf or tray must be installed and secured to the rack before installing the Diamond-VT. Secure the front of the array to the rack with 10/32 screws, locks and flat washers.

Sliding shelf or tray type systems

should never

be used under any circumstances.

Two point open rack system.

The rack must be strong enough to support the Diamond Array properly. Mounting brackets should be moved to the centermost mounting holes and secured using 10/32 screws.

CAUTIONCAUTION

Do not mount multiple Diamond-VT units on a two-rail rack or mount the array above the midpoint of a two-rail rack system.

Do not mount the Diamond-VT on any kind of rail-type system. The array is too heavy and does not have the proper hole pattern for rails.

Insure the Diamond-VT has adequate air flow and continue with the general instructions.

Physical setup

3.2.1 Connecting a Fibre Channel Array

The Diamond-VT supports up to two Fibre Channel Host Interface Cards (HIC). Physical connections and CLI commands contribute to the Fibre Channel topology.

The Diamond-VT may have two Fibre Channel Host Interface Cards (HIC). Each

2 Gb HIC uses

2 SFPs to connect up

to 2 FC cables

HIC is connected by a Fibre Channel cable via an SFP (small form factor pluggable) module into a

point-to-point or loop Fibre Channel topology.

1 Install the SFP according to the manufacturer’s

instructions.

2 Insert the SFP into the Fibre Channel Host

Interface Card in the back of the Diamond-VT.

3 Insert the correct cable.

The cable you use depends upon your application, the environment and the distance required for your storage area network.

To comply with FCC and CE EMI for the 2gigabit Host Interface Card, use fiber optic cables.

Each HIC has two ports and an on-board hub. Each port has an SFP module to connect to Fibre Channel. Each HIC is independent of the other, so that one may be connected into a point-to-point topology and the other into a loop. However, if

one port in a HIC is connected into a point-topoint topology, the other port cannot be used.

One of the advantages of using loop topology for Fibre Channel connections is that it allows Diamond-VT units to be daisy-chained together. See Exhibit 3.2.1-2.

Autoconfiguration

The Diamond-VT automatically determines if the Array HICs are in loop or point-to-point topologies.

If you wish to see how the unit has been set up, go

CLI: Interface via ASCII-

Fibre Channel topology for both HICs on a Diamond-VT. Options are loop only (loop), pointto-point only (ptp), loop preferred (loop-ptp) or point-to-point preferred (ptp-loop).

Loop connects to either an FC-AL arbitrated loop or a fabric loop port (FL_Port) on a switch.

Point-to-point (ptp) connects to a direct fabric connection, such as an F port on a switch.

Loop-ptp allows the Diamond-VT to determine what kind of connection to use, but tries to connect in loop mode first, then point-to-point mode.

Ptp-loop allows the card to determine what kind of connection to use, but tries to connect in point-topoint mode first, then loop mode.

Accessing the array

4.1 In-band CLI Over Fibre Channel

In-band Command Line Interface (CLI) configures and manages the Diamond-VT using SCSI-based CLI commands over a Fibre Channel port connection.

In-band CLI allows a programmer to configure the Diamond-VT while it is moving data. Using a programmer’s interface, CLI commands as described previously in this manual may be implemented.

In-band CLI is implemented as part of LUN 0. It uses a different LUN than the Diamond-VT, and reports as a Storage Enclosure Services (SES) device (device type 0x0D).

LUN 0 is visible on all Fibre ports but is actually a single unit. The default value for LUN 0 is 0x00.

LUN 0 must be reserved for each Write Buffer/Read Buffer pair, using the SCSI Reserve command to insure integrity of the in-band CLI session.

1 An initiator (host) sends a SCSI Reserve

command to LUN 0.

• If LUN 0 is not reserved by another initiator, LUN 0 is now reserved and ready to begin a new CLI session.

• If the Diamond-VT configuration is reserved by a different CLI session (i.e. serial or Telnet), the in-band session is not allowed to modify the Diamond-VT configuration. If you try, the results buffer of LUN 0 returns:

Process X has the configuration reserved.

ID of this session = Y

Ready.

2 The initiator issues a SCSI

command to LUN 0. A must be accompanied by an ASCII buffer representing the CLI command string such as

set DiamondName Omega1

LUN 0 executes the command line and create feedback in the form of ASCII characters into a buffer. This buffer is 8 KB and circular. Retrieve the results by issuing a Read Buffer command before issuing another Write Buffer command.

Write Buffer

command

3 A subsequent Write Buffer command

executes the new command line and overwrites the previous results in the buffer with new results.

4 LUN 0 can be released by issuing a SCSI

Release command to the LUN after each Write/Read Buffer pair, or multiple Write/Read Buffer pairs.

Initiator (Host) Diamond-VT

Reserve LUN 0 return: “ok”

Write Buffer LUN 0 bid ‘AA’ “get Temperature”

Read Buffer LUN 0 bid ‘AA’

Release LUN 0 return: “ok”

executes the CLI command, stores output in buffer

return:”Temperature=28 C\r\n\Ready.\r\n\0”

I/O details

The buffer sent to the Services LUN during the data out phase of a Write Buffer command must be:

• ASCII data

• maximum 80 bytes length

• terminated with either a carriage return character (0x0D), line feed character (0x0A) or NULL character (0x00)

• Characters following the first carriage return character, line feed character or NULL character are ignored.

The buffer retrieved from the Services LUN during the data-in phase of a

Read Buffer

command:

• ASCII data

• 8 KBytes (8192 bytes) in length

• terminated with a NULL character (0x00)

• Characters following the NULL character are meaningless.

A CHECK_CONDITION, INVALID_PARAMETER_IN_CDB is returned

Serial port access

4.3 Ethernet Access: Telnet and SNMP Protocols

The optional 10/100 BaseT Ethernet port provides Telnet- or SNMP-based monitoring and management.

The 10/100 Base T Ethernet management services card provides Telnet-based monitoring and management, including firmware update using FTP.

Remote system monitoring is also available using Simple Network Management Protocol (SNMP). An agent resides in the Diamond-VT which takes information from the Array and translates it into a form compatible with SNMP. If certain conditions arise, the agent sends asynchronous notifications (traps) to a client.

To connect to the Ethernet port

1 Connect a cross-over cable (for a direct

connection to a PC) or regular network cable from a network device to the optional RJ45 Ethernet port on the Ethernet management card on the front of the Diamond-VT.

2 If using a direct connection, power on and boot

up the host computer.

3 Attach a DB-9 null modem serial cable (the

cable must be no longer than three meters) from the RS-232 port of the Diamond Array to a host computer and open a terminal emulator program on the host to set the Ethernet parameters.Turn on the Diamond-VT.

4 First time use: Upon successful power up and

diagnostics, set the host computer with the appropriate settings.

The host computer must have appropriate network settings to allow it to communicate with the Diamond-VT. Please see your system administrator for more information.

To use Telnet

1 If you have not already done so, change the IP

address from the default by first accessing the serial connection and using the CLI.

You may change the IP address to a network specific value or, if the local network uses DHCP, you may enable automatic IP addressing (set IPDHCP enabled) using the CLI.

2 Open a Telnet session on the host computer.

• IP address

• Port type: telnet

• Terminal type: vt100

3 If you make any changes to the network setting

on the Diamond Array, use the

SaveConfiguration Restart

4 Username/password: You are prompted for a

username and password, up to eight characters each, case insensitive. Only one username/password combination is available per Diamond-VT.

• You may change the telnet username and/or password after entering a CLI session using the commands

set TelnetUsername [username] set TelnetPassword [password]

• Or you may change the telnet username and/or password using the Configuration page of the ExpressNAV interface.

• The default username is telnet and default password is diamond

7.0 Configuring the Diamond-VT

The Diamond-VT can be configured as RAID Level 10 or RAID Level 5 with zones and/or Hot Spare sleds. Partitions are created automatically during configuration of Virtual Tape emulation. The default is a single zone which includes all LUNs (devices), all ports and all hosts. RAID is a storage configuration which uses multiple disk drives to increase capacity, performance and/or reliability.

You may configure your Diamond-VT in several different ways depending on your needs although the Diamond-VT makes some choices for you. The following elements must be considered when you are configuring your Diamond-VT:

• RAID level

• Interleave

• Number of tape volumes

• Number of tape drives

• Hot Spare sled option

• Zoning

Using the ExpressNAV browser-based interface is the easiest way to set up your Diamond-VT. You may also use the Command Line Interface commands.

CAUTIONCAUTION

Changing these parameters causes all previous drive data on the Diamond-VT to be erased. Make sure you back up all information before setting up a different configuration.

RAID Level 10

RAID Level 10 (mirroring with striping) increases data transfer rates while ensuring security by writing the exact same data simultaneously to two or more different drives. RAID Level 10 is used in applications requiring high performance and redundancy.

other end to make sure the transmission has not had any errors.

In the Diamond-VT, transmitted data with the added parity data is striped across disk drives. A hardware XOR engine computes parity, thus alleviating software processing during reads and writes.

The Diamond-VT will operate in degraded mode if a drive fails unless you have Hot Spare sleds enabled (see below).

Virtual Tape Volumes

When the Diamond-VT is configured as a Virtual Tape, it is divided into several tape volumes and tape drives based on your choice and the RAID level you choose. See

Virtu al Tape

on page 49.

Hot Spare sleds

In most configurations, if a member of a virtual device becomes degraded, you must swap out the faulted sled as defined in

Instructions

AutoRebuild

on page 69. If you have not enabled

, you must also start a manual

Hot Swap Operating

rebuild.

However, you may designate Hot Spare sleds as replacements for faulted sleds without intervention by you or a host. These sleds, once designated as Hot Spares, are not available for other use.

RAID Level 5

RAID Level 5 increases reliability while using fewer disks than mirroring by using parity redundancy. Distributed parity on multiple drives provides the redundancy to rebuild a failed drive from the remaining good drives. Parity data is added to the transmitted data at one end of the transaction, then the parity data is checked at the

ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual

See

Optional Hot Spare Sled

on page 50 for more

information.

Zones

Zoning is a collection of related Diamond capabilities supporting flexible Diamond-VT configuration management configurable via CLI commands in the Command Line Interface or the

Advanced CLI configuration page of the ExpressNAV interface. Zoning supports security by granting or denying access between initiators and devices as defined by an administrator.

A zone is a collection of devices which can access each other. The devices in a zone usually include one or more initiators, one or more devices, and one or more paths between the initiators and the devices.

The CLI command

RAIDInterleave

allows you to change the size of the sector interleave between RAID groups. The value will depend upon the normal expected file transfer size. If the normal file transfer size is large, the interleave value should be large, and vice versa.

The value entered for the

RAIDInterleave

command refers to blocks of data: one block is equivalent to 512 bytes of data.

Interleave

The interleave size sets the amount of data to be written to each drive in a RAID group. This is a tunable parameter which takes a single stream of data and breaks it up to use multiple disks per I/O interval.

• The default sector interleave in RAID Level 10 is 128 blocks (64k).

• The default sector interleave in RAID Level 5 is 256 blocks (128k).

Valid entries are 16, 32, 64, 128, 256 and SPAN. SPAN, not available in RAID Level 5, indicates that interleave size between the drives in the group will be the minimum drive size of all members in the group.

7.1 Virtual Tape

When the Diamond-VT is configured as a Virtual Tape, it is divided into several tape volumes based on your choice and the RAID level you choose.

Virtual Tape provides increased performance by reducing the time needed to backup and restore data. Virtual Tape volumes reside on Virtual Drives. The Diamond-VT appears to hosts as a tape library, allowing ISV packages to issue a set of tape library commands to perform backup and restore operations to the Diamond-VT.

The underlying storage used for Virtual Tape is specified using the

QuickTape

command.

The simplest way to set up Virtual Tape configurations is to use the ExpressNAV interface. See

Interface

If you use the CLI, the command

ATTO ExpressNAV: Browser-based

on page 23 for more information.

QuickTape

sets

up Virtual Tapes using the following format:

set QuickTape [RAID5|RAID10] [# tape volumes] [# tape drives] <enabled> <Barcode Prefix>

Note

The maximum number of tape volumes and tape drives for RAID Level 5 is 30.

The maximum number of tape volumes and tape drives for RAID Level 10 is 15.

Configuration examples

You may specify the first four to six alphanumeric characters of a tape bar code, used by

ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual

7.2 Optional Hot Spare Sled

To maintain array up time with minimal risk of data loss, individual sleds which fail may be replaced with a spare sled.

In most configurations, if a member of a virtual device becomes degraded, you must swap out the faulted sled as defined in

Instructions

AutoRebuild

on page 69. If you have not enabled

, you must also start a manual

Hot Swap Operating

rebuild.

However, Hot Spare sleds may be designated as replacements for faulted sleds without intervention by you or a host.

Each configuration requires a certain number of Hot Spare sleds. These sleds, once designated as Hot Spares, are not available for other use.

• RAID Level 10: 10 drive sleds and two Hot Spare sleds (sleds 11 and 12).

• RAID Level 5: 10 drive sleds and two Hot Spare sleds (sleds 11 and 12)

• RAID Level 5: five drive sleds (sled positions 1 through 5) and one Hot Spare sled (sled 12).

Note

All arrays using RAID level 10 and Hot Spares options must be fully populated.

If a sled becomes degraded and a Hot Spare sled has been designated:

• the Diamond will replace the degraded sled with the Hot Spare sled, simulating a hot swap of a sled with intervention

• any sled with a Faulted drive will not be used. Faulted sleds maintain their faulted status until they are removed and re-inserted or if the system is restarted.

• Hot Spares are handled as sleds, not as individual drives

• the Hot Spare sled replaces the Faulted sled in the Virtual Device

• a rebuild will automatically start after the Hot Spare is switched into the Virtual Device, even if

AutoRebuild

• the DriveInfo command will list the number of Hot Spare sleds currently in the system

• you can replace the faulted drive or sled later. However, faulted is a non-persistent state. After a power cycle, the faulted sled will display on the DriveInfo screen as having no type, i.e, the type field will be blank. The sled cannot be accessed but must be removed and replaced. If it is replaced, it will become part of any open Virtual Disk in this order:

hot swapping a sled, the new sled becomes part of the existing Virtual Device.

2 if a Hot Spare sled is missing, the new sled will

7.3 Zones

Zoning is a collection of related Diamond-VT capabilities supporting flexible Diamond configuration management configurable via CLI commands in the Command Line Interface mode or in the Advanced CLI Configuration page in the ExpressNAV interface. Zoning supports security by granting or denying access between initiators and devices as defined by an administrator.

To set up zones, use the Command Line Interface

Accessing the Diamond-VT

(see

on page 15) or the Advanced CLI page in the ExpressNAV interface. Zone CLI commands only take effect after you enter the ZoneCommit command.

The individual elements are referred to as device_lun, host_name, port_number and zone_name as defined in Exhibit 7.3-1.

Exhibit 7.3-1 Definitions of zone configuration entries.

zone_name Alphanumeric or ‘_’, character string less

than or equal to 16 characters long

Principles of Zoning

Zoning provides a validation filter for each SCSI command.

Each zone entry includes a named zone, a host portion, a port portion and a device portion. The components of a valid path from a host to a device satisfy the following conjunction:

<host_name> AND <port_list> AND device_list>

The zone

The process:

in this manual.

Each command received by the Diamond-VT is parsed to determine its host/HBA identifier, its port number and the target LUN, forming the zone nexus. This zone nexus is looked up in the defined zones table. If the zone nexus is present, the operation continues; if it is not found, the command is rejected with the appropriate status and sense data.

Two zone configurations accessed through the Command Line Interface regulate zoning:

The Planned configuration

is a work-in-process configuration used to build or edit the desired configuration. The Planned configuration does not control I/O access until it is transformed into the Active Zone Configuration via successful completion of the

ZoneCommit

command.

Other than as a site for zone configuration editing, the Planned configuration has no impact on the Active configuration or the Diamond-VT. Changes to the Planned configuration may be made without considering synchronization with other configuration commands.

Use the

ZoneClearAll

command to clear the

Planned configuration. If, while working in the Planned configuration,

you decide you want to negate that configuration and edit the Active configuration, use the

ZoneRetrieve

command. The information from

Several factors must be considered when configuring a Diamond-VT with zones:

• Be careful when changing Diamond-VT zoning

configurations. Internal validation logic cannot detect misconfigurations.

• The Diamond-VT zoning may be driven by

external applications which handle considerations such as aliasing of parameters.

• Stopping or pausing I/O operations during

zoning changes is the responsibility of the host computer, external to the Diamond-VT.

• You must refer to a device by a consistent LUN

across zones in accordance with Fibre Channel specifications.

• RAID configuration changes require planning and preparation independent of whether any zones are enabled. Such changes affect data integrity, and any write to an incorrect LUN may result in data corruption.

• Degraded operation and RAID rebuilding occur at a lower level than the Zoning features. SCSI command operation continues to operate, and you can modify the Zoning configuration via the ZoneCommit command at any time.

• Zone validation of switch/fabric routing is not supported. The Diamond-VT operates within a SAN environment including host systems, host bus adapters, switches and other devices. The Operating System you use may limit zoning flexibility in your SAN.

• You may create up to 32 zones. Each zone may have up to two ports, up to 24 devices and up to 32 hosts.

Status and Sense Data

Commands sent to a device may be rejected with sense key, code, qualifier as follows:

LOGICAL UNIT NOT CONFIGURED: 68 00 00 No such LUN exists; the initiator does not have access

to this LUN

LOGICAL UNIT NOT SUPPORTED: 25 00 00 The Logical unit is not in an accessible zone

LOGICAL UNIT NOT READY: 04 03 00 The Logical unit is in an accessible zone, but is not

ready; it may be offline or busy

If the logical unit inventory changes for any reason, including completion of initialization, removal of a logical unit, or creation of a logical unit, the device server generates a Unit Attention command for all initiators, telling them a server sets the additional sense code to

internally after the installation of the Diamond-VT. No special operating modes are required and Zoning can be easily installed with no impact on previous configurations. The unrestricted zone can be considered an all/all/all zone: all hosts, all ports and all devices.

Errors

Zone definition tables:

The Zone commands manage entries in the Zone definition tables which manage the overall zoning process. Definition tables are indexed by unique keys

zone_name

(

). All definition tables are repositories for their respective data and participate in establishing the configuration by executing the

ZoneCommit

command.

The integrity of these tables is essential to the data integrity of the Diamond-VT. If the Zone definitions are faulty problems can occur. Although Zone command processing provides a level of command and configuration validation, you must be very careful managing configurations with any zoning system.

Validation of the command line is performed before the command is deemed acceptable to be executed.

These descriptions are generalizations.

• Configuration inaccuracies occurring before

application or operating system data is written to the drives may have no impact on the DiamondVT, but results after an operating system or application have written to the drives are unpredictable.

• Incorrect Zone entries can include misspecification of resources to a zone.

• Verify each command line is properly formed (number of parameters, proper spelling of keywords).

• For commands defining entities, the name being defined must not already be defined.

• If you want to undefine an entity, the name being undefined must already be defined. (A warning will be displayed if the name to be undefined doesn’t exist.)

• World wide port names are validated according to basic format rules. Content verification of WWPN occurs at runtime.

• LUN must be in the range defined by the RAID<n> configuration.

• Errors detected in the CLI command line are described in Exhibit 7.3-1.

• Errors detected while writing the Active Zone Configuration result in an error message and no change to the zoning configuration. The Active configuration continues to match the persistent configuration.

• Errors detected while reading the Active Zone Configuration result in an error message and the zoning configuration remains unchanged.

One tool to support a Diamond-VT is a host computer with an RS-232 port and terminal emulation software. Using this computer, you can hook up a null modem serial cable to the RS-232 port on the Diamond-VT management card and control the array via the Command Line Interpreter (CLI) management software built into the array. The CLI can be used to configure the unit, modify key parameters and read back key system information. (See

Accessing the Diamond-VT

Ethernet Monitoring Port and CLI

on page 15)

If the optional Ethernet management system card has been installed, you may use the RJ45 Ethernet port and Telnet to access the CLI software on the Diamond-VT. Use the same CLI commands to configure, modify or read key systems information (see

Accessing the Diamond-VT

on page

15) or the ExpressNAV browser-based interface. If you restart the array, the Telnet session will end and the session cannot be re-established until the array completes its Power On Self Test.

At power up, the green Diamond Array Ready (RDY) LED is disabled until successful completion of the POST (Power On Self Test) indicating the array is ready for normal operation. If a host computer is hooked to either Fibre Channel or SCSI port, the Ready LED will momentarily blink and then stay lit if the connection is good. If that host is rebooted, the Ready LED will blink again and stay on once the connection is reestablished.

Audible Alarm

The Diamond-VT audible alarm warns of potential problems or faults. It beeps twice at power up to indicate it is operational and will beep repeatedly when the System Fault (FLT) light on the system management card is activated. The alarm will turn off when the fault condition is cleared or the alarm can be disabled by issuing an

AudibleAlarm disabled or PowerAudibleAlarm disabled

Maintenance Services Commands

command via CLI as described in

on page 38. Disabling the alarm for a specific error will not silence the alarm for other errors.

Power On Self Test (POST)

Diamond-VT array is powered up, it will perform a series of internal tests called POST (Power on Self Test). The POST sequence takes from 1 to 2 minutes to complete.

The Diamond-VT LEDs will blink at various points in the test sequence and, if the RS-232 system management port is connected, a list of tests and test results will scroll across the screen. When the POST is nearly complete, all the LEDs on the array will flash simultaneously twice in a row. If the system is fully operational, the ready LED will be lit and the unit is ready to be accessed. If the POST fails, the System Fault LED will be lit and an error code will be flashed.

Power Supply Monitoring

The Diamond-VT monitors the operation of its power supplies and blower assemblies every 30 seconds. If the status changes, the system reports it visually with an LED and a message in the CLI.

If a power supply or blower fails, the management system sends a CLI message and turns off the corresponding power supply LED.

The blower assembly directly adjacent a power supply must be functioning properly for the power supply to work properly. If a blower assembly fails, the power supply will shut down and the management system will send a CLI message. The corresponding power supply LED on the system management card will also turn off.

If a good replacement power supply or blower assembly is inserted into the array, the management system will send a CLI message and the corresponding system management card LED will go on. It may take up to 30 seconds for the system to note these changes.

System Fault LED and Error Codes

If a serious hardware or software error occurs in the Diamond-VT, the System Fault LED will display a series of flashes or blink codes. Error information will be reported via the Command Line Interface if it is operational.

At power up, the green Diamond Array Ready (RDY) LED turns on after successful completion of the POST (Power On Self Test) indicating the array is ready for normal operation.

During operation, the Ready LED will stay lit even if the amber Fault (FLT) LED lights.

If a serious error occurs in the array, the amber Fault LED will flash repeatedly in a blink code pattern:

• an initial series of blinks indicating the system problem

Number of blinks Problem area

4 Fibre Channel interface

5 SCSI interface

8 general internal processing

9 SCSI Enclosure Services

• a two second pause

• another series of blinks providing more detailed information for technical personnel.

• a four-second pause

• the blink code sequence will repeat from step 1 until the error is cleared.

In general, any fault will require notification of Diamond Array technical personnel for resolution or for further debug instructions. When you report

Monitoring, reporting

an error code, please provide both the first and second blink code values.

During a fault condition, more detailed information about the fault may be available via the CLI or the ExpressNAV interface over the RS232 interface port or the optional Ethernet port. These error messages should be reported to technical personnel to assist in debugging the problem.

The blink codes are also saved internally by the array to NVRAM (Non Volatile Random Access Memory) and will be displayed at power up if the power to the array is recycled.

Disk Drive Activity and Disk Fault LEDs

Each dual disk drive sled assembly contains two green activity LEDs and an amber disk fault LED. Once the system has successfully powered up and passed POST, the green activity LEDs are full on and the disk fault LED off.

The Drive 1 and Drive 2 activity LEDs will stay full on when the system is operational and no disk drive activity is present. As the disk drives are accessed, the green LEDs will flash. If the disk drives are heavily accessed the green activity LEDs will appear to flash at a high rate or may even appear to be completely turned off.

The amber disk fault LED will be off under normal operation. If either of the disk drives on a dual disk drive assembly reports a disk error of

any kind, the amber disk fault LED will come on. The disk fault LED can be activated by minor issues such as a disk drive writing to a bad sector (which is usually corrected by the disk drive the next time it writes) or major issues such as a head crash or complete drive failure.

When the disk fault LED is turned on, the system will issue a detailed message via the CLI. These messages are not written permanently to the error log file but should be recorded to help assess the disk problem.

If the disk drive error is a non fatal error and the drive is still functional, the array will continue to read and write data to the disk drive but the disk fault LED will remain on. If you repeat a drive command or action and it completes successfully, the disk fault LED may have been set by an anomaly in the disk drive. You can clear the Disk Fault LED by either power cycling the array or issuing the

Maintenance Services Commands

SledFaultLED

command in CLI as per

on page 38

If you repeat a disk command or action and the disk fault LED remains on, the disk error may be serious. You should write down the error message issued by the CLI and contact technical support via the means easiest for you for assistance (see

Warranty

on page A-xv). If you choose to replace the suspected faulty dual disk drive sled assembly, follow the appropriate procedures.

9.3 Rebuilding RAID Level 5 and 10 Configurations

If a sled must be removed and a new sled inserted into the Diamond Storage Array while it is configured in a RAID Level 5 or 10, you must rebuild the RAID Level using CLI commands or the ExpressNAV interface.

WARNING

Selecting RAID parameters causes all previous drive data on the Diamond Storage Array to be erased. Make sure all of your information is backed up before setting up RAID groups.

When you initially set up RAID groups using the

QuickRAID

command, groups are synchronized automatically because there is no pre-existing data on the drives. However, drives may display as “degraded, and you need to set all LUNs to OK status.

The simplest method to check RAID group status is to access the

10.1 Hot Swap Operating Instructions

To maintain array up time, individual disk drive sled assemblies, power supplies and blower assemblies can be replaced with the unit fully operational. Special instructions need to be followed to perform these operations.

Disk Drives

CAUTIONCAUTION

• Individual disk drive sled assemblies may be replaced while the array is operating with no other intervention only if there is absolutely no activity on that drive.

• Failure to ensure no activity may destroy any data on that drive and possibly stop the entire Diamond-VT operation. Please follow the instructions below using CLI commands to replace drives.

• Do not leave empty openings on the front or rear of the Diamond-VT under any circumstances. Empty openings affect airflow and may cause the unit to overheat and shut down.

• All modular components must be replaced by qualified personnel only. Components are electrostatic sensitive. Use a static wriststrap when handling any of the cards inside the Diamond-VT. Use proper grounding methods. Always store spare components in proper ESD containers when not in use.

Follow your backup procedures before removing a sled. You may copy drives using the appropriate CLI commands (See

41).

The following method is the safest way to perform a hot swap of a drive.

The general approach: identify the disk drive sled to be replaced, take it offline using the appropriate CLI commands, turn off its power using CLI commands, remove and replace with a new disk drive sled, power up the new sled, and place back on line.

1 Connect to Diamond-VT services (see

Hazardous voltage and stored energy hazard when removing power supplies.

In a system with at least one operational power supply, the other power supply can be successfully removed and replaced without powering the system down and with no loss of array functionality. The green activity LED on the front of the system management card identifies the operational status of each power supply (Green means the power supply is operating correctly).

Note

System command overlap is discontinued across some drives when only one power supply is operational.

Labels on the rear of the Diamond-VT point to the appropriately related A and B power supplies.

1 Identify the power supply to be swapped on the

rear of the unit. 2 Turn off the power supply on/off switch. 3 Disconnect AC line cord. 4 Unscrew the two screws on the power supply

with the appropriate tool. 5 Pull power supply out of chassis using the

power supply module handle. 6 Install new power supply in chassis with proper

orientation (Power supply is keyed and can only

be inserted one way). 7 Tighten the two screws on the power supply

with the appropriate tool. 8 Connect AC line cord 9 Turn on power supply switch. 10 Verify correct operation by observing that the

on page 57).

Blower Assemblies

CAUTIONCAUTION

Do not leave empty openings on the front or rear of the Diamond-VT under any circumstances. Empty openings affect airflow and may cause the unit to overheat and shut down.

The Diamond-VT contains two blower assemblies. The blowers are critical to proper array cooling operation. However, the array can operate with only one functional blower within certain ambient temperatures. The blowers are electronically connected to the power supplies and a power supply will not run without its corresponding blower assembly operating. This means if the blower adjacent to power supply A is removed, the ‘A’ power supply will shut down, turning off the corresponding LED on the system management card. The CLI will issue a message about the power supply being turned off.

To replace a blower assembly

1 Unscrew the two screws on the blower

assembly with the appropriate tool. 2 Pull the blower assembly out of chassis. 3 Install new blower assembly in chassis with

proper orientation (Blower assembly is keyed

and can only be inserted one way). 4 Tighten the two screws on the blower assembly

with the appropriate tool. 5 Verify correct operation by observing that the

green light is lit on the rear of the power supply,

and that the appropriate power supply green

light on the system management card on the

front of the unit is also on.

Fibre Channel technology

Fibre Channel (FC) is a serial communication interface designed to transfer large amounts of data among a variety of hardware systems over long distances. It is becoming a key technology for applications that require shared, high-bandwidth access to storage.

Fibre Channel provides a logical point-to point serial channel for the transfer of data between a buffer at a source device and a buffer at a destination device. It moves buffer contents from one port to another, without regard to the format or meaning of the data, allowing different upper level protocols to run over the Fibre Channel connection.

The Fibre Channel architecture is a hierarchical set of protocol layers. Defined within these layers are rules for signal interfaces, serial encoding and decoding, error control, frame format and communications protocols. Fibre Channel provides a range of implementation possibilities and purposely isolates the transmission medium from the control protocol so that each implementation may use the technology best suited to the application.

Fibre Channel arbitrated loop (FC-AL) technology allows 127 systems and devices to be distributed over

a range of up to 10 kilometers running at speeds of 1 gigabit/sec. Multiple FC-AL loops can be connected via a fabric switch topology to extend the range.

SAN technology

A Storage Area Network (SAN) is a shared storage architecture. SANs connect computers and storage devices for online data access. Each connected system can directly access any attached storage device. A SAN maintains greater fault tolerance and load balancing by supporting server clustering and fail-over (the ability for one server to take over for another in the event of a failure.

SCSI protocol

SCSI (pronounced scuzzy) stands for Small Computer System Interface, a processor-independent standard for system-level interface between a computer and SCSI devices such as hard disks, CD-ROM and printers, and to other computers and local area networks.

The protocol has many standards specifying data transfer rates, data width and speeds which allow SCSI devices to exchange data and control signals with a computer's CPU. Each device connected to a SCSI bus must have a different SCSI ID.

Term Definition

arbitrate process of selecting one L_Port from a collection of ports which ask for use of the arbitrated

loop at the same time

arbitrated loop a loop topology in which two or more ports are interconnected, but only two ports can

communicate at one time

ATA Advanced Technology Attachment: A disk drive interface standard, formerly called IDE; the

ATA specification deals with the power and data signal interface of an integrated disk controller and drive

auto negotiation hardware senses and automatically responds depending on configuration

CLI Command Line Interface: used by applications and advanced users to perform diagnostic

or configuration tasks; access is available through a computer terminal or terminal emulator via connections to the RS-232 port or the optional Ethernet management services card via the local area network using Telnet

fabric A FC switch or two or more FC switches interconnected to physically transmit data between

any two N_Ports on a switch or switches

Appendix B ATA Disk Technology

ATA is the dominant disk drive technology today and will be for the foreseeable future. It offers all the cost advantages of a mass produced, consumer-driven technology which is rapidly being driven forward. Today ATA also offers all the performance and reliability features needed to create high performance ATA-based disk storage arrays.

We view ATA as the perfect disk drive technology for “in-the-box” disk storage array solutions.

Aggregated Data Interface Technology (ADXT

™

) with its built-in Virtual Device Manager (VDM), Data Routing Fabric (DRF) and ATA Interface Engines (AIE) smoothly and efficiently organizes Fibre Channel data streams for storage or retrieval on ATA disk drives. ADXT provides end users with the power and sophisticated data control needed to take moderately priced ATA disk drives combine them in a disk storage array and power them to the performance levels of SCSI or Fibre Channel disk arrays

ATA disk drives are used in the enormous PC marketplace and an estimated 85% of all disk drives sold today contain an ATA interface. Shipments of ATA drives are expected to grow rapidly over the next five years with increasing consumer and business demand. In general, ATA disk drives are the “driver” of all disk storage technology as the costs, volumes and demands of the PC marketplace are the primary focus of the world’s largest disk drive manufacturers.

ATA disk drives today offer capacities comparable to SCSI and FC disk drives – although at a tremendously lower cost. Advances in platter and head technology will push drive capacity along a very steep curve in the next five years. The chart below summarizes ATA and other disk interface standards. It clearly indicates that ATA drive technology offers characteristics that ideally suit it for “in the box” usage in high capacity, high performance disk arrays.
