1 Introduction Welcome Congratulations on the purchase of your new ST8000 Disk Expansion Unit (DEU). The DEU provides a superior fault-tolerant network storage solution in a subsystem-based SAF-TE compliant RAID enclosure. The SAF-TE compliant interface provides a standard, non-proprietary means for the RAID subsystem to automatically integrate with peripheral packaging that supports status signals, hot swapping drives and enclosure monitoring.
Hot Swap Power Supplies — Dual hot swappable power supplies expandable to three, all with current sharing circuitry. Power supply system provides monitoring and sequencing. Cooling — Dual high capacity cooling fans. Notifications — LEDs and audible alarms provide failure notifications. Inside door panel Fault LEDs provide drive failure identification.
Storage Management Solution — Enterprisewide managing and monitoring software. Where to Find Answers When you have questions about your DEU there are several places you can look to find answers. Refer to the following: In this guide: This user’s guide provides detailed information for installing and using the DEU disk array subsystem. The manual assumes that the reader is already familiar with the operating system environments where the DEU will be installed.
Front Panel Components The DEU front panel comprises seven major components: Operator Control Panel, Power-On Indicator LED, Status Indicator LEDs, Alarm Speaker, Door Lock, Status LEDs, and Activity LEDs. Operator Control Panel (OCP) Speaker Status Indicator LEDs Channel Mode LED Door Lock Power Supply LED Fan Status LED Power-On LED Status Indicator LEDs Note: LEDs normally visible only when illuminated, shown here for identification.
The OCP provides a four line by twenty character display. There are five function keys for a menu driven interface. An animated icon will appear on a static display and provides an “at-a-glance” look at system status. When a “happy” animated face appears, all systems are indicating a nominal state. When the animated face changes to a “sad” face, the system indicates that a problem has been detected and requests your attention.
Ch an n el Mo d e The Channel Mode LED indicates the status of the array subsystem by changes in its color and state. When illuminated steady green, the LED indicates normal array activities. When the LED changes to amber (flashing or steady) it indicates abnormal activities, for more information see LED Descriptions described later in this guide. Po w er Su p p l y Statu s The Power Supply Status LED indicates the condition of the power supplies by changes in its color.
Door Lock The front door has an integral lock that also serves as a door handle. In addition, the door lock provides security to deter unauthorized access to the internal components. Two keys are provided with the system. To unlock the door, insert the key and turn it in a counterclockwise direction. To lock the door, turn the key in a clockwise direction.
Rear Panel Components The DEU rear panel comprises four major components: I/O Interface cards, power cord connector module, fuse, and access doors to power supplies and fans.
The I/O Interface card incorporates built-in automatic SCSI termination. When the data cable is plugged in, the system automatically senses the connection and provides the required SCSI termination. Two sets of jumpers are provided on the card. One set routes Term Power in the event that the host controller is not providing it. The next set of jumpers addresses a specific set of controllers that use the DEC Fault Bus protocol.
Optional Bay for Ultra S2S RAID Controller SAF-TE Card Fault LEDs Power On/Off Switch Hard Disk Drive Drive Rails Note: Cover shown cut-away to illustrate recessed power switch. I/O Interface Card Cooling Fan #2 Power Supply #3 with PSU Cover Plate Cooling Fan #1 Power Supply #2 I/O Interface Card “DC Good” LED Power Supply #1 Hot Swappable Disk Drives The DEU uses high performance, 3.5-inch form factor hot swappable disk drives.
The drive mounting design incorporates a rail system with built-in connectors making it possible to “hot swap” a drive without shutting down the system. This design allows for easy installation with minimal force and latching clips to secure the drives into place. Note: All drives in an array should be of the same capacity. If the drives are mixed, all of the drives in the array are assigned the capacity of the smallest size drive.
Located in the tower-based systems’ top bay or the rack-mount systems’ far left bay are two card slots. The Ultra S2S RAID Controller (optional) and the SAF-TE card are installed in these two slots. The Ultra S2S RAID Controller will be installed in the upper most (or furthest left) slot. The SAF-TE card is installed in the next slot down or to the right. Hot Swappable Cooling Fans The cooling system consists of two high-performance fans fitted to the rear panel.
If a failure occurs, the Power Supply Status LED will illuminate amber and the audible alarm will sound. The user can identify the failed component by accessing the OCP and viewing the “Hardware Status.” The PSU “DC Good” LED will not be illuminated on the failed power supply, see Replacing a Power Supply described later in this guide. PRINTER NOTE: Page size 9” x 9.25”. Align this page to top, right hand corner. Back box bleeds off top and right edge. Left side of page extends to 9.25 inches.
Configuration Modules The DEU is available in two bus configurations which is determined by the configuration module installed. The Dual-Bus module provides for a split bus design, while the Single-Bus module connects both SCSI buses together that can be used when all drives are required on one SCSI bus. The Single-Bus module is larger in physical size than the Dual-Bus module and is easily identified by a description silk-screened on the module card.
SAF-TE The DEU is designed to be compliant with SAF-TE (SCSI Accessed Fault-Tolerant Enclosure) specification version 1.0. Under this specification, the enclosure is implemented as an assignable SCSI target ID. This allows standardized alert detection and status reporting using the SCSI bus as the underlying transport mechanism. Disk drives, power supplies, cooling fans and temperature are continually monitored and these conditions are then reported over the SCSI bus to the host system.
2 Installation Setup The installation of your DEU disk array subsystem is essentially a three-step process: the subsystem is setup and its components installed, the cabling is completed based on the supported configurations, and the array is then configured. The DEU is designed with an open architecture that allows for many possible combinations of cabling schemes.
Guidelines Before installation, you will need to consider the following: ■ When referencing a component on the rear panel it is assumed the user is facing the rear panel and when referencing the front panel components the assumption is that the user is facing the front panel. ■ Interior temperature of the rack cabinet should be maintained at ambient temperatures but must not exceed 117°F (47°C) during normal operation.
Rack-Mount Subsystem Assembly Install the DEU into any standard IAE 19" rack cabinet. Caution: Ensure that the location of the DEU does not create an unstable condition when installed in the rack cabinet enclosure. Note: Mount the subsystem into the rack enclosure before installing the disk drives. This will reduce the weight required to support during installation. 1 Select an appropriate location in your rack cabinet for the DEU.
2 Locate the two support brackets. Mount the two brackets to the rack cabinet verticals using the four screws, two washers, and caged nuts provided. The bracket has a slotted hole and a countersunk hole. Mount the slotted hole on the rear vertical. The slotted hole receives a “pan head” screw with a washer and the countersunk hole receives a “flat head” screw.
Component Installation Caution: Disk drives and printed circuit board components are sensitive to electrostatic discharge. To prevent operating failure or damage, observe the following: Establish a ground for yourself by using the wrist grounding strap, or by touching the metal chassis prior to handling or installing the drives or printed circuit board components. 1 Down your server or power off your computer system in preparation for installing the controller.
Populate drive bays from the lower (right) slot first. Upper (left) bay, four drive slots Drive Label Component side Lower (right) bay, four drive slots Single-Bus module: Begin populating the drive with the far right slot or lowest slot and work to your left or up. 6 Fully seat the drive by applying light pressure with your thumb to the front of the drive. 7 Press the Drive Latching Clips until they ‘snap ‘ into place. The drive is now locked into position.
Installing the Third Power Supply If you will be installing five (5) or more disk drives you will be required to install the third power supply. Note: There is no need to power off the DEU or the computer system. The power supplies are hot swappable. 1 Loosen the two screws on the Power Supply #3 cover plate using a flat-blade screwdriver and remove the cover plate. 2 Remove the power supply from its shipping package.
Cabling Configuration This section provides the recommended cable configurations when operating the DEU in a specific mode. The Ultra Wide SCSI mode provides enhanced performances with data transfers up to 40 MBs per second (20 MHz). Note: Be sure to enable the Ultra SCSI (Fast-20) mode in the SCSI Adapter Setup. The DEU supports the American National Standard Ultra SCSI (Fast-20) parallel interface standards, referred to as Ultra Wide SCSI.
JP3 and JP4 Fault Bus Protocol Jumpers (Add to disable termination) Ch an ne l 0 Ch an ne l 1 Channel 0 and 1 Term Power Jumpers I/O Interface Card Cables Cable length is another consideration when configuring the subsystems. When considering the total length of your cabling requirements, the internal length of cables and printed circuit board traces (known as the internal cable length) must be subtracted from your total cable length. The DEU internal cable length is 36 inches.
Note: Shielded data cables, such as those provided with the subsystem, must be used to prevent radio frequency interference. It is recommended that you use the cables provided with your system. These cables have been tested and meet stringent guidelines set forth by SCSI-3 ANSI specifications. Ultra Wide SCSI Mode Several possible configurations exist for the DEU in Ultra Wide SCSI mode.
1 Connect one end of a one meter data cable to the Channel #1 connector on the Ultra SCSI Controller. 2 Connect the other end of the data cable to the Channel 0 SCSI connector on the right side or upper I/O Interface card. 3 If required, connect one end of the second one meter data cable to the Channel #2 connector on the Ultra SCSI Controller. 4 Connect the other end of the second data cable to the Channel 1 SCSI connector on the right side or upper I/O Interface card.
7 After setting the cabinet identifications you must power cycle the subsystem. Observe normal power cycling precautions by waiting a minimum of five (5) seconds before adding power again. This will reset the SCSI IDs to a default setting that prevents a SCSI ID conflict under normal conditions. 8 Power up your computer system and run the configuration program. This completes the hardware installation.
Single-Bus Cabinet Configuration Ultra Wide SCSI Data Cable (1 meter) TOP Ultra SCSI Controller Host Computer Ch 0 Ch 1 I/O Interface Card I/O Interface Card Ch 1 Ch 0 Ch 1 Note: SCSI termination in the DEU is automatic and requires no user configuration. Refer to “Cabling Configuration” described earlier for information on systems using DEC Fault bus protocol. 3 Turn on the power to the DEU. After the power-on self-test has completed, Status and Channel Mode LEDs will be solid green.
Other Configurations There are many possible combinations of controllers and cabling schemes when configuring the DEU subsystems. The sample configurations in the previous sections provide the basic configurations. However, the DEU is based on an open-architecture expandable subsystem and allows for customization to fit your current or future needs. Note: For additional configuration options while operating under the Ultra Wide SCSI mode, refer to Appendix D. PRINTER NOTE: Page size 9” x 9.25”.
3 Using the DEU Power-On Self Diagnostics When the DEU is powered on, it will perform a power on self-test (POST) procedure. If no errors are detected, all of the Status Indicator LEDs will illuminate solid green. During the diagnostic self-test a continuous tone will sound and the following will be observed: The Operator Control Panel will display “Testing ROM”, “NVRAM”, and “SCSI Access” followed by the startup mode screen and the Status OK (default) screen, provided no errors are detected.
Any of these failures will generate the following: Channel Mode LED will blink amber eight times and the speaker will sound eight tones. The Channel Mode LED will change to green and normal operations will be attempted after the tones are sounded. These failures indicate that the LEDs and audible alarm functions may not be reliable. RAM Read/Write Failure - This indicates that one or more bytes of the microprocessor RAM failed a write/read test.
SCSI Bus Access Failure The Channel Mode LED will blink amber four times and the speaker will sound four tones. This indicates that either the SCSI controller failed to respond to a reset command or another device has control of the SCSI bus. Note that this may be caused by other devices having control of the bus at the time the DEU is powered ON. After the tones have sounded, there will be a two second delay, and the microprocessor will again attempt to initialize the SCSI controller.
LED Descriptions Use the following LED description matrix to determine the status of the DEU LEDs when the SAF-TE card is installed and the RAID controller is powered on.
Operator Control Panel The Operator Control Panel is used to control and monitor the power supplies and fans. The user can also change SCSI IDs for the drives and SAF-TE processor, monitor the cabinet temperature or change the temperature threshold for the monitoring system. Other menu functions provide for viewing component system status, silencing the alarm, establishing a passcode to protect SCSI ID options, and reading the firmware.
Startup Screens The following are sample screens that could occur during the startup POST operation for normal conditions and abnormal conditions: STARTING DUAL-BUS CONFIGURATION STATUS : OK MENU MENU ENTER ESCAPE Startup Screen ENTER ESCAPE Status OK Screen Normal Screens STATUS : HARDWARE ¸ ERROR STATUS : HEAT THRESHOLD EXCEEDED MENU MENU ENTER ESCAPE Temperature Exceeeded Screen ENTER ESCAPE Hardware Error Screen Abnormal Screens If one of the errors occur during the startup, you will hav
If you install five (5) or more drives with only two (2) power supplies installed, an alarm will sound, the Power Supply LED will illuminate steady amber, and the OCP display will indicate “Non-Redundant Power.” Install a third power supply and the display will clear followed by the Power Supply LED will return to steady green.

B Glossary The following terms are used throughout this manual and may be helpful background information on the technology. Asynchronous Operations Operations that bear no relationship to each other in time and can overlap. The concept of asynchronous I/O operations is central to independent access arrays in throughput-intensive applications. Cache Flush Refers to an operation where all un-written blocks in a Write-Back Cache are written to the target disk.
fault tolerance. This rebuild operation will be carried out by the controller automatically when a SCSI disk drive fails. Logical Drive A set of contiguous chunks of a physical disk. Logical disks are used in array implementations as constituents of logical volumes or partitions. Logical disks are normally transparent to the host environment, except when the array containing them is being configured.
3 and 5, all data and parity blocks are divided between the drives in such a way that if any single drive is removed (or fails), the data on it can be reconstructed using the data on the remaining drives. (XOR refers to the Boolean “Exclusive-OR” operator.) SAF-TE Is the acronym for SCSI Accessed Fault-Tolerant Enclosures. It is a monitoring and communication specification developed by Conner (nStor) and Intel for sending and receiving server and storage system status information via the SCSI bus.

D Option Cards Introduction The Ultra Extender and Differential Converter Option cards provide a single solution allowing the extension of device connectivity and/or cable length of the SCSI bus for the DEU subsystems. When the Ultra Extender card is used, the circuitry functions as a SCSI bus repeater for multiple singleended to single-ended cabling schemes while being electrically isolated from each other.
Features The following are major features of the Option Cards: Dual Configurations — Both cards available in single and dual channel models. High Speed Transfers — Asynchronous or synchronous data transfer rates up to 40 MBs with Ultra Wide SCSI. No Required SCSI ID — Does not consume a SCSI ID on the SCSI bus. Fast-20 Support — Complete support for SCSI-3 (Fast-20) and backwards compatible with SCSI-2 standards. Active Negation — Employs TolerANT active negation technology.
Quick Install The following procedures outline the steps necessary to setup your DEU subsystems. These guidelines are generally for those individuals who don’t like to read manuals. Install the Disk Drives — Open the front door of each cabinet and insert the disk drives. Be sure each drive seats properly and the drive latches are secured. Install the Option Cards — Install the correct Option cards in the correct slot for your configuration. Connect the Cables — Connect the data and jumper cables.
DEU Subsystem Installations Setup This section contains the procedures to install and configure the Ultra Extender and Differential Converter Option cards in your DEU disk array subsystems. The installation is essentially a three step process: the cards are installed in the DEU subsystem, the cabling is completed based on the supported configuration, and the array is then configured. Several rules will apply when cabling and configuring multiple cabinets in a “master/slave” environment.
Cabling Configuration The cabling configuration is divided into two subsections in this section, configurations pertaining to Single-ended Ultra Wide SCSI and those for Differential Ultra Wide SCSI. These two sections are divided into groups describing the cabinet/cabling scheme and provide the recommended cable and termination configurations when operating the DEU in a specific mode. Cable length is a primary consideration when configuring the subsystems.
Di fferen ti al SCSI According to SCSI-3 ANSI specifications for Differential Ultra Wide SCSI, the total SCSI cable length is 25 meters (984 inches). The internal SCSI bus of the DEU is a Single-ended bus and therefore a conversion is required when interfacing to an external differential SCSI bus. The DEU supports Differential SCSI by using the Differential Converter Feature card. This card provides the termination and drivers necessary to interface to a differential SCSI bus.
Note: Shielded data cables, such as those provided with the subsystem, must be used to prevent radio frequency interference. It is recommended that you use the cables provided with your system. These cables have been tested and meet stringent guidelines set forth by the SCSI-3 ANSI specifications. G u i d el i n es Before installation, you will need to consider the following: Identify which DEU subsystem will be the “master” subsystem and which will be the “slave” subsystem(s).
I n stal l ati o n Precau ti o n s Please observe the following cautions and notes prior to and during installation: Printed circuit board components are sensitive to electrostatic discharge. To prevent operating failure or damage, observe the following: Establish a ground for yourself by using the wrist grounding strap, or by touching the metal chassis prior to handling or installing the printed circuit board components. Exercise care when handling any electrical component.
Single-Ended Ultra Wide SCSI Prior to beginning the cabling, identify the configuration for your installation. Note the card locations in the illustrations for each configuration. Install your cards and connect the cables based on the procedures and diagrams shown. The diagrams depict the configuration using the minimum number of controller channels.
