    Enclosure variants The 2U chassis can be configured as a controller enclosure (DS6200, DS4200, or DS2200) or an expansion enclosure (DS EXP) as shown in Table 3 Table 4. The 5U chassis can be configured as a expansion enclosure (DS EXP) as shown in Table IMPORTANT: The 2U and 5U core products–including key components and CRUs–are described herein.
  • Page 26: 2U Enclosure Core Product

    IMPORTANT: DS Series and DS EXP/D3284 storage enclosures support dual-controller configuration only. If a partner controller fails, the storage system will fail over and run on a single controller module until the redundancy is restored. For RBODs and EBODs, an IOM must be installed in each IOM slot to ensure sufficient air flow through the enclosure during operation.
  • Page 27: 2U Enclosure Rear Panel

    2U enclosure rear panel Numeric designators on PCMs and alphabetic designators on IOMs indicate slot sequencing for modules used in 2U enclosures. PCM and IOM modules are available as CRUs. The DS6200 and DS4200 RBODs use 4-port controller modules, whereas the DS2200 RBODs use 2-port controller modules. The DS Series RBODs support the DS EXP EBODs for optionally adding storage.

    IMPORTANT: Drawer sideplanes—also known as side cards—can be hot-swapped as field-replaceable units (FRUs). However, these FRUs require a special tool, and replacement should be performed by qualified service personnel. For additional information, contact support.lenovo.com, select Product support and navigate to Storage Products.
  • Page 35: 5U Enclosure Chassis

    The 2U enclosures use a redundant PCM that integrates a power supply and cooling fan within the same CRU module, as shown in Figure 22 (page 30). Conversely, the 5U enclosures use separate CRU modules for power supply and cooling/circulation, respectively. Figure 28 shows the power supply module, which provides the enclosure with power connection and a power switch.
  • Page 36: Operator's (Ops) Panel

    Opening a drawer does not interrupt the functioning of the storage system, and DDICs can be hot-swapped while the enclosure is in operation. However, drawers must not be left open for longer than 2 minutes, or airflow and cooling will be compromised. IMPORTANT: During normal operation, drawers should be closed to ensure proper airflow and cooling within the enclosure.

    Power cooling module – 2U enclosures AC-DC power is provided by up to two auto-ranging Power Cooling Modules (PCMs) with integrated axial cooling fans. The IOMs control fan speed. Also see “System airflow” (page 40) for optimal cooling within the enclosure(s).
  • Page 40: System Airflow

    PCMs are hot-pluggable, and replacement should only take a few seconds to do. Replacement must be completed as soon as possible after the removal of the defective PCM to avoid a thermal exception. The replacement procedure should be completed within an absolute maximum of 2 minutes. IMPORTANT: Operation of the enclosure with any modules missing will disrupt the airflow, and the disks will not receive sufficient cooling.
  • Page 41 Dual PSUs provide redundant power for the 5U system: if one PSU fails, the other keeps the system running while you replace the faulty module. PSUs are hot-swappable. Replacement of a PSU can be performed while the enclosure is running, but the procedure must be completed within two minutes of the removal of the defective module.
  • Page 42: Fan Cooling Module - 5U Enclosures

    Fan cooling module – 5U enclosures The five fan cooling modules (FCMs) at the rear of the enclosure maintain all system components below their maximum temperature, assuming the ambient temperature is below 35ºC. Fan speed within the FCMs is governed by the controller modules.
