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
J
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

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.

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

Components
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.

page of the ExpressNAV interface.
CLI command specifies the
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.

3.2.2 Connecting a SCSI Array
The SCSI Diamond-VT uses a VHDCI connector and SCSI cables to connect to a host. It automatically detects the type of Host Interface Card it is using without any intervention.
To connect the SCSI Diamond-VT
1 Insert a SCSI VHDCI connector into the Host
Interface Card in the back of the Diamond-VT.
2 If the SCSI Diamond-VT is the last device on
the bus, you must attach a VHDCI terminator to one connector of the SCSI Host Interface Card

In-band SCSI over Fibre Channel
In-band SCSI commands (Write Buffer and Read Buffer) may be issued to the Diamond-VT Fibre Channel port to manage configuration via two mechanisms:
• In-band CLI over SCSI, where ASCII CLI
commands, may be issued via CLI commands except
• ID/value, where the application program uses a
SCSI CDB (command descriptor block) to select the buffer ID of the configuration parameters to be affected, and the new value of the parameter. Most configuration options are available.

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
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”

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.
