  • Page 28: Controller Enclosure Interface Components

    2: The Controller Enclosure Controller Enclosure Interface Components The rear of the controller enclosure can accommodate up to eight minihub canisters: Up to four front end (host) and up to four back end (drive) minihubs (Figure 2-3). Each minihub has two Fibre Channel connectors. You connect the host- or drive-interface cables to the respective minihubs.

  • Page 29: Minihub Types

    Controller Enclosure Interface Components Minihub Types The TP9400 uses two types of minihubs: GBIC and SFP. GBIC Minihubs GBIC minihubs are used with 1 GB interface controllers. Each minihub requires 2 GBIC modules, which are installed in the Fibre Channel connectors, as shown in Figure 2-4. GBIC minihubs have a maximum data transfer rate of 1 GB/s.

  • Page 30: Figure 2-5 Sfp Minihub With Sfp Transceiver

    2: The Controller Enclosure SFP Minihubs SFP Minihubs are used with 2 GB interface controllers. Each SFP minihub requires 2 SFP transceivers, which are inserted in the Fibre Channel connections. Refer to Figure 2-5. Note: You may be required to remove the lower SFP from the minihub in some configurations.

  • Page 31: Controller Enclosure Components

    Controller Enclosure Components Controller Enclosure Components The controller enclosure has owner-removable and replaceable components called “canisters.” Following are descriptions of each of these components. Controller Canister Each controller comes in a removable, portable unit, called a controller canister (Figure 2-6). The controller canisters slide into one of two controller slots on the front of the controller enclosure and attach to hosts via Fibre Channel connections.

When using a single-controller array, the controller must be installed in slot A.
  • Page 33 Controller Enclosure Components If a controller canister fails, the Controller Fault indicator on the affected controller canister will glow. For more information about indicators, see “Checking the Controller Enclosure Indicator Lights” on page 36. When you replace a failed controller, and if certain NVSRAM bits are set, the firmware on the new controller is automatically synchronized with the firmware on the second controller (the one currently managing the array) controller.

  • Page 34: Battery Canister

    2: The Controller Enclosure Battery Canister The battery canister houses rechargeable batteries and a battery charger board. The battery canister plugs into the front of the controller enclosure (Figure 2-7). The battery provides backup power only to the controllers’ cache memory. All data stored in memory will be preserved as long as the batteries can sustain power to the cache memory.

  • Page 35: Controller Fan Canister

    Controller Enclosure Components You can hot swap the battery canister, replacing it while the controller enclosure is in operation, however, use the TPSSM7 storage management software to make sure that there is no data in cache and that all caching is stopped before you remove a battery canister.

  • Page 36: Figure 2-8 Controller Fan Canister

    2: The Controller Enclosure Controller Fan Canister Side Lever Indicator Lights Lower Handle 54067-f Controller Fan Canister Figure 2-8 To prevent cooling problems, the controller enclosure must have proper air circulation throughout the chassis. Cooling problems include any malfunctions or obstructions that impede air flow and cause one or more components in the controller enclosure to overheat.

    Controller Enclosure Components Rear View Front View 54082 Controller Enclosure Air Flow Figure 2-9 Both fans failing simultaneously in the controller fan canister is unlikely. Such a failure would cause either one or both controllers to overheat. Under these circumstances, the amber controller indicator on the front may turn on.

  • Page 38: Fan/Communications Canister

    2: The Controller Enclosure If a fan fails, the fault indicator on the fan canister will glow. For more information about indicators, see “Checking the Controller Enclosure Indicator Lights” on page 36. If you replace the fan canister and continue to experience problems, the controller enclosure may have defective components or connections.
  • Page 39 Controller Enclosure Components You can hot swap the fan/communications canister, replacing it while the controller enclosure is in operation, as long as you complete the exchange within 15 minutes from the time you remove the failed unit until you seat the new one. It is unlikely that both fans in the fan/communications canister would fail simultaneously.

Minihubs 1 and 3 correspond to the top controller (controller A) and minihubs 2 and 4 correspond to the bottom controller (controller B). Each minihub provides host loop capability and self-diagnostic features.

    5: The Drive Enclosure Air Vent Locking Lever Latch 48099-a Figure 5-4 Drive Sleds and Drive Numbering Fan Canister The drive enclosure’s cooling system consists of two fan canisters, each containing two fans. The fan canisters circulate air inside the drive enclosure by pulling air in through the vents on the front of the drive sleds and pushing the air out the vents in the rear of each fan canister (Figure 5-5).

    Drive Enclosure Components canister fails, the second fan canister continues to provide sufficient cooling to operate the drive enclosure. To prevent cooling problems, the drive enclosure must have proper air circulation throughout the enclosure. Cooling problems include any malfunctions or obstructions that impede air flow and cause one or more components in the drive enclosure to overheat.
