Preface This guide will take the technology-savvy user through the installation and maintenance of the Diamond Storage Array-VT. The Diamond-VT was designed to meet your need for large amounts of easily accessible storage using proprietary Aggregated Data Transfer Technology (ADXTJ) to merge the power of multiple, high performance ATA disk drives with the sustained data transfer rates required by sophisticated computer users. Your comments help us improve and update our products.
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.
• Aggregated Data Transfer Technology (ADXTJ) for high performance/scalability • Ultra ATA 100 megahertz (Mhz) • RAID Level 10 and RAID Level 5 configurable • Zoning capability compatible with third party servers, switches and with deliverables from industry standards organizations.
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 merges the performance of multiple ATA drives together to achieve sustained, full bandwidth Fibre Channel data transfer rates.
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: Redundant Array of Inexpensive Drives. Over time that definition became Redundant Array of Independent Drives and the inherent cost advantage in a RAID system was lost.
3.0 Installation Instructions If you are familiar with the Diamond-VT, Fibre Channel, SCSI and RAID configurations, you may set up and configure the Diamond-VT using these instructions. Find details, illustrations and other guidance for more involved operations and special cases in the rest of this manual. CAUTION Before configuring the Diamond-VT, ensure that any computer data to be stored on the array is properly backed up and verified.
6 Follow the screens to find information about the array or to configure the array from the factorydefault settings. The Diamond-VT may be set up in a RAID Level 5 or RAID Level 10 configuration with or without Hot Spare sleds and/or set up in a zoned configuration. If the Diamond-VT is not attached to a DHCP server and you wish to change the defaults 1 At the Ready prompt after POST (see above), type set IPAddress [desired IP address].
3.1 Diamond-VT Components The Diamond-VT has been designed to be easy to use, maintain and upgrade. It features a durable steel outer case and modular components in either a floor or a rack mount model. Immediately upon receipt, check the shipping carton for damage from mishandling. Contact us at once via the means that is easiest for you (see Warranty on page A-xv) if the carton has been mishandled or displays any signs of damage.
Rack mount model The system management card is at the left front of the case. Intelligent midplane (internal) At its center is a DB-9 serial System Management Card RS-232 port which allows a connection for setup, monitoring and upgrade of the unit from any computer system with an RS-232 interface. The optional 10/100 BaseT Ethernet management services card enables Telnetbased monitoring and Disk drive sleds (12) management. It also provides the ability to update the firmware in the array via FTP.

Immediately upon receipt, check the shipping You can mount the Diamond-VT using two sets of carton for damage from mishandling. Contact us rail pairs spaced to accommodate the overall at once by the means easiest for you (see Warranty length of the unit (approximately 23 inches).
General Instructions 1 Insert the proper connector into the Host Interface Card in the back of the Diamond-VT. (See Connecting a Fibre Channel Array on page 11 or Connecting a SCSI Array on page 13). 2 Connect the cable (Fibre Channel or SCSI) from your host system to the Host Interface Card connector on the back of the DiamondVT. The cable you use depends upon your application, the environment and distance.
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 HIC is connected by a Fibre 2 Gb HIC uses Channel cable via an SFP 2 SFPs to connect up to 2 FC cables (small form factor pluggable) module into a point-to-point or loop Fibre Channel topology.
Exhibit 3.2.1-2 Possible 2 gigabit Fibre Channel physical connections depending on which Fibre Channel connection mode has been selected.
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. or connect a cable between the second connector and the next device on the SCSI bus. To connect the SCSI Diamond-VT 1 2 Insert a SCSI VHDCI connector into the Host Interface Card in the back of the Diamond-VT.
14 SCSI connections
4.0 Accessing the Diamond-VT Communicate with the Diamond-VT through the Fibre Channel link, the RS-232 port or the Ethernet port using Command Line Interface commands or ATTO ExpressNAV, an integrated user management console. You may configure and tune the Diamond-VT for different environments and applications, update the firmware, monitor internal power and temperature status, report on hardware diagnostics and log failures.
SNMP SNMP, or Simple Network Management Protocol, is an application layer protocol that allows network devices to exchange management information. Through a combination of standard and custom MIBs (Management Information Base), the Diamond-VT provides status and error indications to an SNMP server, allowing the Exhibit 4.0-1 Array to be managed with other devices in a complex system through a common interface. You use CLI commands to configure up to six unique Trap addresses.
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. 3 A subsequent Write Buffer command In-band CLI allows a programmer to configure executes the new command line and overwrites the Diamond-VT while it is moving data. Using a the previous results in the buffer with new programmer’s interface, CLI commands as results.
to an initiator that specifies an incorrect Buffer ID, Mode, Length or Buffer Offset. The Mode is Exhibit 4.1-2 always Data (0x2), the Buffer ID is always 0 and the Buffer Offset is always 0. The SCSI command process: reserve the Diamond-VT, send the command, release the Diamond-VT.
4.2 Serial Port Access The Diamond-VT provides remote service operations over the RS-232 serial port using standard terminal emulation software available with most systems. The Diamond-VT supports service operations over the RS-232 serial port using standard terminal emulation software available with most systems. • 8 bit ASCII 1 • flow control none Connect a DB-9 null modem serial cable between the port marked RS-232 on the front of the Diamond-VT and one of the computer’s serial ports.

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.
8 Call technical support (see Warranty in the Appendix, page xv) to get the appropriate MIB file for your Diamond-VT. 14 The SNMP management software contacts the agent in the Diamond-VT. The screen displays system information. 9 For each client, copy the MIB file to the directory containing the SNMP management software. 15 Status is monitored and reported through the SNMP management software. 10 From within the SNMP management software, compile the file attodmnd-mib.
5.0 ATTO ExpressNAV: Browser-based Interface The easiest way to communicate with the Diamond Storage Array is to use ATTO ExpressNAV, a user-friendly GUI interface accessed through a browser to control the most common capabilities of the array. Access ATTO ExpressNAV from any browser that supports the latest standards for XHTML 1.0 and CSS1. To take full advantage of the ExpressNAV interface you should have Java script enabled through your browser. Minimum requirement is for Internet Explorer 5.

46 CLI: configure drives
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.
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. Interleave The interleave size sets the amount of data to be written to each drive in a RAID 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.
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 Hot Swap Operating Instructions on page 69. If you have not enabled AutoRebuild, you must also start a manual rebuild. However, Hot Spare sleds may be designated as replacements for faulted sleds without intervention by you or a host.
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. A zone is a collection of devices which can access each other.
the Active configuration will be copied into the Planned configuration. To determine what is in the Planned configuration, type ZoneInfo Planned. Active configuration is persistent and establishes the Diamond zoning configuration after powerup. The Planned configuration becomes the Active configuration after successful execution of the ZoneCommit command. The Active configuration is replicated as the Planned configuration after the successful ZoneCommit, after power-up and after ZoneRetrieve.
Configuring Zoning CAUTION Be careful when changing Diamond-VT zoning configurations. Internal validation logic cannot detect misconfigurations An unrestricted zone configuration, exactly mimicking the LUN configuration, is created internally after the first power-up or restart after installation of the Diamond-VT. No special operating modes are required and Zoning can be easily installed with no impact on previous configurations.
Errors 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.
8.0 Updating Firmware Engineers, technicians and/or system administrators/integrators may update the firmware of the Diamond-VT using the Command Line Interface (CLI) (See Accessing the Diamond-VT on page 15) via the RS-232 serial port or the optional Ethernet management services card. Updating firmware via the RS-232 serial port To update the firmware via a connection to the RS-232 serial port, you will need 5 In the Send File box, enter the current Diamond flash (“...”.
3 The Diamond should acknowledge receiving the file and display a message not to interrupt power for 90 seconds. Copy the latest Diamond-VT image file (“...”.ima) onto the host computer and note its directory c:\diamond\flash\“...”.ima 4 CAUTION Change directories to the place where you copied the “...”.ima file Do not interrupt the flash process. If the process is interrupted, the Diamond-VT will become inoperable and will have to be returned to the factory for repair.
9.0 Diagnostics, Upgrade and Maintenance The Diamond-VT provides a number of visual, audible and computer system-generated indicators to identify the operational status of the array. System status and error information is readily available. Various methods are available to correct problems or to upgrade equipment and firmware. RS-232 Monitoring Port and CLI One tool to support a Diamond-VT is a host computer with an RS-232 port and terminal emulation software.
midplane temperature were to reach a higher point, the temperature warming alarm will report Critical, the Array will be taken off line, and all disk drive activity will be disabled.

9.1 Troubleshooting The Diamond-VT provides a number of indicators to identify the operational status of the array. System status and error information is readily available. If your situation is not defined here or elsewhere in the manual, if these solutions do not help, or if you have any questions or concerns about any aspect of operating the Diamond-VT, contact technical support.
• Follow the instructions in the appropriate chapters of this manual to remove, replace and reconfigure the drive such as Hot Swap Operating Instructions on page 69. • You may copy drives by using Command Line interface commands. Refer to Drive Management Commands on page 41. If a power supply fails • Verify the power cord is correctly plugged and there is power at the power receptacle. • If there is power, the cord is secure and the blower and power supply LEDs are off, replace the blower unit.
9.2 Resetting Defaults Resetting the Diamond-VT to defaults will not alter the RAID configuration, zoning configuration, IP configuration or Telnet information. However, resetting the Diamond-VT to factory defaults is a last-ditch effort to recover from corrupt configurations or complete failure. All data will be lost, but the zoning configuration will remain. CAUTION Data will be lost if you follow these procedures. Make sure you have no other choice before resetting the Diamond-VT to factory defaults.

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.
To synchronize mirrored drives manually The most efficient method to synchronize Virtual Tape configurations is to enable Hot Spares or the auto rebuild feature. 1 2 3 Connect to Diamond Storage Array services via the RS-232 port or the optional Ethernet management services card (see Accessing the Diamond-VT on page 15). You should now be in CLI. Access the RAID page of the ExpressNAV interface (see ATTO ExpressNAV: Browser-based Interface on page 23).
10.0 Hardware Maintenance The disk drive sleds, blower assemblies, power supplies, host interface cards, and system management card may be replaced with identical or upgraded parts. CAUTION 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.
