  • Page 17: Introducing The Controller Enclosure

    Chapter Introducing the Controller Enclosure The Compaq StorageWorks Model 2100 and 2200 Ultra SCSI controller enclosures use Ultra SCSI buses to transmit and store data within up to six storage enclosures. This chapter describes the enclosure and its major elements, called customer replaceable units (CRUs), and various enclosure options.

  • Page 18: Product Description

    Figure 1–2. Model 2200 controller enclosure Product Description The Compaq StorageWorks array controllers process host data and distribute this data (at the same rate) over six buses to storage enclosures. The controller enclosure is connected to the storage enclosure with single-ended, 16-bit (wide) Ultra SCSI bus cables. Table 1–1 lists the elements (devices) this enclosure accommodates and their functions.

  • Page 19: Prerequisites

    Always install a blank panel in any bay not currently in use. NOTE: Compaq recommends using blank panels at all times for any empty enclosure element location to prevent a potential overtemperature condition. Since only two ECB bays are used at any one time—one per cache module—install a blank in any vacant ECB bay.

  • Page 20: Figure 1-3. Major Element Mounting Locations (Front And Rear)

    1–4 Model 2100 and 2200 Ultra SCSI Controller Enclosures User Guide All of these elements (except the redundant power supply and the EMU) are essential elements for normal enclosure operation. Without the EMU, the enclosure loses some features and functionality, but data storage capabilities continue as normal. Any empty element bay requires the installation of a blank assembly.

  • Page 21: Enclosure Power

    CAUTION: Proper cache module operation requires an ECB module for each cache. Refer to the array controller documentation for information about using controller sets and ECBs. The following Compaq StorageWorks array controller types function properly within the enclosure, using controller-compatible cache memory and a supported array controller software (ACS) version: Model 2100 enclosures —...

  • Page 22: Ultra Scsi Buses

    1–6 Model 2100 and 2200 Ultra SCSI Controller Enclosures User Guide Ultra SCSI Buses Array controllers receive data from a host, process this data, and through ports, distribute the data over single-ended, 16-bit, Ultra SCSI buses to the storage enclosures. Each bus has 16 possible SCSI bus addresses (IDs): 0 through 15.

  • Page 23: Options

    Introducing the Controller Enclosure 1–7 Options This section describes additional elements that can ordered by the user to maximize enclosure capabilities. Upgrading a Model 2100 Enclosure to a Model 2200 Enclosure A Model 2100 enclosure can be upgraded to a Model 2200 enclosure by installing additional hardware.

  • Page 24: Ultra Scsi Bus Cables

    AC_FAIL CXO6772A Ultra SCSI Bus Cables Compaq recommends using the shortest cable length possible to connect storage enclosures. The maximum supported cable length is 3 m (9.8 ft). Table 1–3 lists the available bus cables. Table 1–3 Ultra SCSI Bus Cables...

  • Page 25: Operating The Enclosure

    Chapter Operating the Enclosure This chapter describes configuration rules for the enclosure, startup and shutdown procedures, and fault detection. The Ultra SCSI configuration rules apply to the storage device side of the enclosure, but do not apply to the host side of the array controller. Other chapters in this guide contain detailed information about individual element functions, operations, and error conditions.

  • Page 26: Raid Controllers

    Controller B is the redundant controller and always uses SCSI bus ID 6. No other device on the bus can use this address. Compaq RAID array controllers support Ultra SCSI (40 MB/s) 16-bit (wide) storage devices. CAUTION: If a conflict exists between array controller configuration information and this document, use information in the array controller documentation.

  • Page 27: Power Application And Removal

    Operating the Enclosure 2–3 Power Application and Removal To turn O the enclosure, apply power to the AC power supply. Shutting down the enclosure involves quiescing the controllers and disconnecting the AC power cords from the enclosure power supplies. Turning the enclosure O causes the following actions to occur: Power supplies output +12 VDC and +5 VDC for enclosure operations.

  • Page 47: Figure 7-1. Fan Locations

    Chapter Fans This chapter contains information about the fans, including product description, configuration, functionality, and status indications. Proper enclosure operation requires establishing and maintaining the right operating environment as specified in Appendix A. This operating environment involves establishing and maintaining the correct ambient temperature. Failure to maintain a proper operating environment might cause the elements to malfunction and compromise data integrity.
  • Page 48 7–2 Model 2100 and 2200 Ultra SCSI Controller Enclosures User Guide Temperature is monitored by the EMU (see Chapter 3) using an intake air temperature sensor and stored high-limit temperature settings. If an overtemperature condition is detected by the EMU, the EMU directs all operational fans to function at high speed, increasing air flow and cooling throughout the enclosure.
