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 37: Raid Controllers

    RAID Controllers RAID Controllers Each TP9300 controller enclosure can contain one or two 2882 or one or two 2822 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.

    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 40: 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 41: 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.

  • Page 44: 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 45: 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.
