  • Page 29: Storage Enclosures

    Chapter 2 Storage Enclosures The storage enclosure is the basic building block of the TP9300. Each storage enclosure provides redundant power and cooling to its individual components. The storage enclosures also house the I/O components of the storage system. There are two types of storage enclosures: controller enclosures and expansion enclosures.

  • Page 30: Overview

    Important: Several references are made in this chapter to the storage management software (TPSSM). For complete information on the operation and use of this software, see SGI TP9400 and SGI TP9500 Software Concepts Guide (007-4305-00x) Figure 2-1 shows a front view of the storage enclosure.

    2: Storage Enclosures Disk Drives Each storage enclosure can contain up to 14 low-profile Fibre Channel disk drives. Controller enclosures can be cabled to as many as seven expansion enclosures for a total capacity of 112 disks in one storage system. Each disk is mounted in a sled for ease of installation and removal.

  • Page 35: Raid Controllers

    RAID Controllers RAID Controllers Each TP9300 controller enclosure contains two 2882 RAID controller modules. These controllers slide into the same opening that the ESMs occupy on the expansion enclosures. Each controller contains RAID logic, cache memory, a rechargeable battery for the cache, and additional environmental monitoring circuitry. Each controller also has two labels on its rear panel: one shows the MAC address of the controller and one shows the battery service date (see Figure 2-4).

  • Page 37: Environmental Status Modules (Esms)

    Environmental Status Modules (ESMs) Environmental Status Modules (ESMs) The expansion enclosures contain environmental status modules instead of 2882 RAID controllers (see Figure 2-5). Each environmental status module contains an environmental services monitor board and two slots for SFPs (small form-factor pluggables).

  • Page 38: Fans

    2: Storage Enclosures Fans The storage enclosures each have two fan units. These fan units are mounted in the rear of the enclosure (see Figure 2-6). They pull air through the front bezel to cool the internal components of the enclosure. The air is exhausted out the rear of the fan units. The fans provide redundant cooling of the enclosure.

  • Page 39: Power Supplies

    Power Supplies Power Supplies Each storage enclosure contains two power supplies. These power supplies provide power to the other components in the enclosure by converting incoming AC voltage to DC voltage. The power supplies are redundant: if one supply fails, the other power supply can keep the enclosure running until the failed unit can be replaced.

This switch assigns a unique identifier to every enclosure in the system. The controller enclosure should always have its tray ID set to “00.” The first expansion enclosure should be set to “01.”...

  • Page 42: Link Rate Switch

    2: Storage Enclosures Link Rate Switch The link rate switch is located on the same panel as the enclosure ID switch, between the power supplies on the rear of the enclosure (see Figure 2-9). The link rate switch controls the speed of the Fibre Channel connections to the enclosure. This switch should always be set to 2 Gbit/s.

  • Page 43: Sfp Transceivers

    SFP Transceivers SFP Transceivers An SFP (small form-factor pluggable) transceiver is a module that fits into the interface connectors on the RAID controllers and the ESM modules (see Figure 2-10). Every Fibre Channel cable that connects to a RAID controller or ESM module requires an SFP transceiver.

  • Page 46: Figure 3-1 Turning The Power On And Off

    3: Operating Storage Enclosures To turn on the enclosure after a normal shutdown (as described in “Turning the Power Off” on page 32), turn on both power switches on the rear of the enclosure (see Figure 3-1) or the main circuit breaker, whichever is applicable. You must turn on both power supply switches to take advantage of the redundant power supplies.

  • Page 47: Turning The Power On After An Unexpected Shutdown

    Turning the Power On after an Unexpected Shutdown Turning the Power On after an Unexpected Shutdown The enclosure (and the entire storage array) may shut down unexpectedly under the following conditions: • If the internal temperature of the enclosure exceeds the maximum operating temperature (an overtemp condition).

  • Page 48: Turning The Power On After An Overtemp Shutdown

    3: Operating Storage Enclosures In the expansion enclosures, the overtemp indicator on the environmental status module º º illuminates if the temperature reaches 40 C (104 F). If both power supplies shut down, the overtemp indicator cannot come on. See Figure 3-3 on page 37 for the location of the overtemp indicators on expansion enclosures.

  • Page 49: Turning The Power On After An Emergency Shutdown

    Turning the Power On after an Unexpected Shutdown Turning the Power On after an Emergency Shutdown To restart the enclosure after a power failure or emergency shutdown, follow these steps: After the emergency situation is over or power is restored to the site, turn off all power switches (see Figure 3-1 on page 28).

  • Page 50: Turning The Power Off

    3: Operating Storage Enclosures Turning the Power Off The enclosure is designed to run continuously, 24 hours a day. However, you may need to turn the power off for maintenance, such as upgrading the drives or replacing certain modules.To turn the power off, follow these steps: Use TPSSM to determine the status of your system components and any special instructions before proceeding.

  • Page 51: Monitoring Status With Software

    TPSSM provides these procedures. Caution: If the software recovery procedures are not followed, data loss can result. Note: For more information on the storage management software (TPSSM), see the SGI TP9400 and SGI TP9500 RAID Administration Guide (007-4306-00x), the SGI TP9400 and SGI TP9500 Software Concepts Guide (007-4305-00x), and the SGI Storage Area Network Installation Instructions (108-0252-00x).
