  • Page 23: Array Controllers

    RA8000 and ESA12000 Storage Subsystems 1.2.1 Array Controllers Either an HSG80 Fibre Channel array controller or an HSZ80 UltraSCSI array controller can be used. The array controller presents the storage devices to the host system as another device connected to one of its I/O buses. The array controller then processes the I/O requests to the storage devices of the subsystem.

  • Page 26: Single-Ended I/O Module (Se I/O)

    Chapter 1. Product Description The subsystem enclosure supports single-ended, Ultra Wide storage devices. The configuration rules for the SCSI buses are as follows: • All devices and ports in the same column are on the same SCSI bus or port •...

  • Page 27: Expanding The Ultrascsi Bus

    (see Figure 1-9). These connectors are wired in parallel and act as a tri-link connector. In an expansion configuration, Compaq recommends that maximum cable length not exceed 1.5 m (4.6 ft.) between enclosures. Compaq supplies a cable kit, DS-BNK37-IE, containing the necessary cables to connect an expansion unit.

  • Page 28: Controlling The Internal Scsi Bus

    Chapter 1. Product Description 1.2.3.2 Controlling the Internal SCSI Bus The I/O module controls the internal SCSI bus in the following manner: • Isolates the internal SCSI bus from the external SCSI bus. • Provides single-ended SCSI bus termination. • Disconnects the internal SCSI bus from the external SCSI bus when the EMU so directs.

  • Page 29: Maximum Bus Length

    RA8000 and ESA12000 Storage Subsystems 1.2.3.6 Maximum Bus Length The maximum bus length, including external cables (distance from the I/O module terminator to the last terminator on the bus) is a function of the bus speed and the number of devices. If the external bus is configured point to point (from SE I/O module-to-SE I/O module with no devices installed in between), the cables may be extended to 20 meters due to the isolation and re-timing circuitry of the SE I/O module.

  • Page 30: Environmental Monitor Unit (Emu)

    Chapter 1. Product Description 1.3.2 Environmental Monitor Unit (EMU) The primary function of the EMU (see Figure 1-10) is to monitor, process, report, and display enclosure and array controller environmental status information for the power supplies, temperature, blowers, configuration, SCSI addressing, I/O modules, communications, and the EMU microcode version.

  • Page 33: Power Verification And Addressing (Pva) Module

    RA8000 and ESA12000 Storage Subsystems 1.3.3 Power Verification and Addressing (PVA) Module Proper operation of the subsystem, whether it be a master or an expansion enclosure, requires both a PVA module and an EMU module. The PVA (Figure 1-11) and its associated EMU ensures that all major UltraSCSI components are functioning properly.

  • Page 34: Monitoring Power Supply Operation

    1) Ensures that there is a minimum of four operational power supplies in the enclosure. If the PVA senses less than four power supplies, it notifies the EMU. 2) Allows the user to select the Compaq-supported device SCSI bus addresses for the master and each expansion enclosure.

  • Page 35: Master Enclosure Controlled Power Shutdown

    RA8000 and ESA12000 Storage Subsystems Therefore, both the EMU and PVA monitor all of the power supplies (a maximum of eight) to ensure that at least four are operational. An error condition is indicated by one of the following conditions: •...

  • Page 36: Expansion Enclosure Initiated Power Shutdown

    Chapter 1. Product Description 4) A controlled power shut down is completed on all the subsystem cabinets. NOTE If the master EMU is not communicating with the array controller or the array controller does not support a controlled shut down, the master EMU commands all enclosures to perform an immediate power shut down.

  • Page 39: Power Supply Sbbs

    RA8000 and ESA12000 Storage Subsystems Power Supply SBBs CAUTION The subsystem requires power supply SBBs rated for at least 180 W such as the DS-BA35X-HH. You cannot use lower rated supplies, such as the 131 W (DS-BA35X-HA), the 145 W (DS-BA35X-HD), or the 150 W (DS-BA35X-HF).

  • Page 40: Standard (4 + 1) Power Configuration

    It is not used for the redundant (4 + 4) configuration. This standard power configuration (Figure 1-15) is the minimum configuration Compaq recommends. If a power supply SBB fails you might be able to replace it before a second fails.

  • Page 41: Redundant (4 + 4) Power Configuration

    Redundant (4 + 4) Power Configuration A full redundant power configuration requires two separate power sources, two ac entry power controllers, and eight shelf power supplies (Figure 1–16). Compaq recommends this configuration to provide complete power system redundancy. Any one of the following error conditions will cause the subsystem to cease operation: •...

  • Page 42: Figure 1-16 Redundant Power Configuration (4 + 4)

    Chapter 1. Product Description The second, or redundant, ac source provides power to ac power entry controller B. The four power supply SBBs on the right end of each shelf are connected to power bus B with the four gray power cords. Figure 1–16 Redundant Power Configuration (4 + 4) SHR-1152 EK–SMCPR–UG.

  • Page 43: Ecb Sbbs

    The external cache battery (ECB) SBB provides power to the RAID array controller cache module if system power fails. The cache module in turn provides power to the ECB during normal operation. Compaq supplies two versions of ECBs: a single-battery ECB for single-array controller configurations and a dual-battery ECB for dual-redundant array controller configurations.

  • Page 44: Product Description (Continued)

    In the RA8000, the ECB SBB is mounted at the top of the pedestal. In an ESA12000 cabinet, the ECB SBB is mounted in the middle front of the cabinet between the BA370 enclosures. A Y-cable connects the ECB to the array controller cache module. The cache is mounted under the array controller and is identified by the single plug in the middle of the module (Figure 1–18).

  • Page 47: Setting The Pva Scsi Address

    The second expansion cabinet (if used) address is 3. In an expansion subsystem, no two enclosures can have the same address. 3) Compaq does not support any PVA address that assigns SCSI bus device addresses 6 or 7 to any storage device.

  • Page 48: Compaq Supported Master Pva Address

    Chapter 1. Product Description 1.11.1 Compaq Supported Master PVA Address Compaq supports PVA address “0” only for the master enclosure. Figure 1–21 defines the SBB device IDs for a master enclosure, first expansion, and second expansion units. The device addresses are denoted to the right of Figure 1–21.
